Chapter 2 Introduction
2.1
DESCRIPTION
PESA’s Enterprise DRS (EDRS) Audio Router is a high channel capacity implementation of the
traditional DRS Distributed Routing System for audio and time code signals. Using modular system
integration, EDRS systems may be configured up to a system maximum of 7680 inputs x 7680 outputs.
Functionally, Enterprise DRS is virtually identical in hardware interface, set-up, configuration and
operation to the traditional DRS router. This EDRS User Guide is intended as a supplement to PESA
publication 81905905890, Technical Manual , DRS Distributed Routing System, covering the traditional
DRS router. If you are not familiar with the traditional DRS system, PESA recommends that you take
the time to read the aforementioned manual and establish a solid understanding of the DRS system
before proceeding with this guide. Configuration, set-up and operation are all done through user
interface screens of PESA’s Cattrax software control application.
The key difference in the two systems lies in the Data Exchange Engine frame. Enterprise DXE (EDXE)
frames offer a much higher signal handling capacity and can interface with up to 24 DRS I/O signal
frames to support a maximum of 1536 input signals and 1536 output signals; whereas traditional DXE
frames can interface with up to 8 signal frames and support a maximum of 512 input signals and 512
output signals.
When expanding a system beyond the 1536 x 1536 signal handling capacity offered by a single EDXE
frame, each Enterprise DXE frame can interface with up to 4 additional EDXE frames for a system total
of 5 data exchange frames and a total signal handling capacity of 7680 x 7680.
Both EDXE and traditional DXE frames interface to the same input and output signal frames. All
information, pin-outs and hook-up data for signal frames presented in the traditional DRS Technical
Manual is applicable when interfacing a signal frame to an EDXE frame.
Both traditional DRS and EDRS incorporate high-speed time division multiplex (TDM) technology for
signal distribution, rather than a crosspoint matrix array; allowing input signal, output signal or
combination input/output signal frames to be distributed remotely from one another as needed for a
particular installation. Figure 2-1 is a front view of a typical DRS rack frame with the front cover in
place.

Chapter 3 System Architecture
3.1
OVERVIEW OF SYSTEM ARCHITECTURE
Just as with a traditional DRS router, there are basically three different types of chassis frames used in
an EDRS system: audio signal frames, time code signal frames and Enterprise Data Exchange Engine
(EDXE) frames. Figure 3-1 illustrates component layout for a typical signal frame (top illustration) and
EDXE frame (bottom illustration).
Figure 3-1 Frame Component Layout (Typical)
EDRS routing systems are implemented in terms of signal blocks. All audio signal frames process 128
audio channels – either as a single block of 128 channels (dedicated input or output frames), or two 64
channel blocks (split frames). Each audio block supports one signal type (input or output) and one signal
format (AES digital or analog). Time code frames support 64 physical input or output channels, but
occupy a single block of 128 signals. Signal types and formats can not be mixed within a block.
Dedicated input frames are configured as a single 128 channel block and accept 128 input channels of
one signal format – AES or analog. Dedicated output frames are also configured as a single 128 channel
block and provide 128 output channels of one signal format – AES or analog.
Split frames process 128 audio channels as two blocks of 64 channels each and may be configured as
mixed signal inputs, mixed signal outputs or as one input block and one output block. Figure 3-2
pictorially illustrates the concept of dedicated and split audio frames.
This concept of channel blocks is key to configuring a DRS router and connecting signal frames to
EDXE frames. Numerous frame variations are possible using channel block architecture – these are
introduced in Paragraph 3.2.

AUDIO FRAMES
Audio frames are the DRS system components that interface with external input or output audio signals.
Regardless of the variant, all audio frames have the capacity of processing 128 audio signals. Audio
frames are available in the following channel block variants:
•
•
•
•
•
•
•
•
128 input channels of one signal format - AES or analog
128 output channels of one signal format - AES or analog
128 total input channels, divided as two 64 channel blocks – AES and analog
128 total output channels, divided as two 64 channel blocks – AES and analog
64 input channels – AES, 64 output channels - AES
64 input channels – analog, 64 output channels - analog
64 input channels – AES, 64 output channels - analog
64 input channels – analog, 64 output channels – AES
All audio signals are processed by the DRS as digital data. Analog inputs are converted to digital data
for routing and AES signal pairs are decoded and routed as two independent mono channels. Any audio
input signal to DRS, whether derived from an AES or analog input block, may be routed to an analog
output block channel where DAC circuitry converts the digital signal to an analog output. AES outputs
are always paired channels and each signal of the pair may be individually selected from any decoded
AES input signal or from any mono analog signal. Depending on the choice of frame signal-handling
capacity and distribution, it is possible to use the DRS as a format converter. For example, routing an
analog input to an AES output channel provides not only a router function but also analog to AES
conversion capability. In similar manner, routing an AES input to an analog output channel provides
AES to analog conversion.
Every audio frame is composed of a rear panel, circuit board, and up to two power supply/controller
modules. Each audio frame is configured with one of the following rear panel types, depending on
signal handling requirements and the type of connector(s) used in the installation. Available connector
types and signal handling capabilities of each are presented in the chart below. An illustration of each
rear panel is shown in Figure 3-3.

BNC connectors are used only for connection of AES audio signals, each of
which contains a pair of audio channels. In order to accommodate 128
signals, only 64 connectors are required; and to accommodate 64 signals,
only 32 connectors are required.
There are several variations of circuit boards, depending on the signal type and I/O mix of the frame.
Only one circuit board is used in any given frame, and the type of card used determines the signal
handling characteristics of the frame.

Each frame also contains a mid-plane assembly which routes signals and voltage sources between the
rear panel, the power supply/controller module and the circuit card. There are no active components on
the mid-plane board, and the only component of interest to the user is a sixteen position rotary switch
mounted to the circuit card side of the assembly. This switch is for possible future product
implementations and is not used in DRS applications covered by this manual. Setting position of this
switch on an audio frame has no effect on DRS system operation.
3.3
REAR PANEL CONNECTIONS – AUDIO FRAMES
Regardless of the rear panel or circuit card used, the intra-system connectors are the same for each audio
frame variation. These connections are shown and identified in Figure 3-4 using the ELCO/EDAC
connector rear panel for example only. Connectors identified by Figure 3-4 are identical for all rear
panel styles.
Figure 3-4 I/O Frame Rear Panel Connections (Typical)
TDM Bus Connector There are two TDM bus connectors (RJ-45) located on the rear panel of each
signal frame. These are the LOWER connectors located on each side of the frame rear panel. When
viewed from the rear of the frame the left-hand connector is the Primary DXE Connector and the
right-hand connector is the Redundant DXE Connector. These are interface point(s) for the signal
frame TDM bus to the DXE Frame. When only one DXE frame is used, connect a CAT-5E cable
between the Primary DXE connector and the DXE. In a redundant system, connect the Redundant DXE
connector to the second (redundant) DXE frame.
Power Cord Connector Access Each power supply/controller module is fitted into a chassis slot
(either slot 1 or slot 2). When a power supply is installed, its 3-prong power receptacle is accessible
through this opening on the frame rear panel. Each power supply carries its own dedicated power
receptacle. Input power is not bussed between modules. When two power supplies are used (for
redundancy) a separate power cord must be attached to each receptacle through its access port. Each
access port is equipped with a harness device that secures the cord to help prevent accidentally
disconnecting the frame from its power source.
There is a second RJ-45 connector located above the TDM bus connector on each side of the frame rear
panel and also a pair of BNC connectors located on the lower right-hand side of the rear panel. These
connectors are intended for future product implementations and are not used in DRS applications
covered by this manual.

TIME CODE FRAMES
DRS Time Code frames contain a specially designed circuit card to route 64 channels of time code data.
For all practical purposes a time code frame may be considered identical to an audio frame with respect
to frame component layout and connections between frames. Time code signal frames are available with
BNC, 6-pin detachable or ELCO connectors. Pin-out data for time code is different for ELCO and 6-pin
detachable connectors from audio pin-outs for the equivalent connector, and is provided in Chapter 5 of
this manual. Time code and audio frames may be mixed within a system, provided input signals of each
format are only routed to an output block of the same signal format.
3.5
ENTERPRISE DATA EXCHANGE ENGINE FRAMES
Enterprise Data Exchange Engine (EDXE) frames process and distribute data on the TDM bus between
signal frames. Each DXE frame interfaces with up to 24 signal frames through one of the 24 I/O Frame
Port connectors on the rear panel using CAT5x cable. A signal frame and EDXE may be separated by
up to 100 meters in length when CAT5E cable is used. Each I/O Frame Port connector interfaces to a
single signal frame, and supports the 128 channels of the frame – either as a dedicated block of 128
channels, or two 64 channel blocks. A single EDXE can interface with up to 24 frames, for a maximum
signal handling capacity of up to 1536 input signals and 1536 output signals. In the case of a system
expanded beyond 1536X1536, multiple EDXE frames are used; up to a system maximum of five EDXE
frames, for a total system signal-handling capacity of up to 7680 inputs and 7680 outputs.
Each EDXE frame contains at least one frame controller device, co-resident with the power supply on a
specialized component called the Power Supply/PERC1500 Controller Module, which communicates
with the router system controller, such as a PERC2000. As with any PESA router installation, the
system controller communicates with the various router system components and control panels, and
orchestrates unified operation of the system through the frame controllers contained in each individual
router frame. PESA’s PERC2000 is available in a stand-alone rack frame with power supply, or the
system controller circuit card may be mounted in a Cheetah video matrix switcher chassis. In either
application, the system controller is connected to EDXE frames over a 10/100 Ethernet link. All
operational parameters, adjustments and configuration of the Enterprise DRS system are made through
PESA’s Cattrax control software application.
In DRS system architecture, the two power supply/controller slots are identified by the nomenclature
primary (slot 1) and redundant (slot 2); and the controller device installed in slot 1 is identified as the
“primary” controller, the controller in slot 2 is identified as the “redundant” controller, refer to Figure 31 for slot locations. Note that this is a naming convention only and in systems with redundant control
capability does not indicate whether a controller is operating as the “active” device or the “standby”
device. For systems with only one power supply/controller module, the single module is always
installed in the primary controller slot, and is the active controller for the frame. Redundant power and
control systems have a module installed in each slot. One of the modules is always active, and the
second module is operating as the standby controller – regardless of the slot in which each is physically
located. During redundant controller operation, the standby controller maintains contact with the active
controller in order to remain current with all operating status and parameters for the frame, and also to
monitor the health of the active controller. Should errors occur with the active controller, or if an
operator manually initiates a controller changeover command, the standby controller assumes active
control of the frame, and the previously active module becomes the standby controller.

Every EDXE frame is composed of a rear panel assembly, up to two power supply/PERC1500
controller modules, and an EDXE circuit board. There are no variations of the components comprising
an EDXE. The rear panel assembly provides all connectors needed for intra-system connection, and a
pair of loop-thru sync reference input BNC connectors. A mid-plane routes signals between the rear
panel and the circuit board as well as power rails and control signals between the power
supply/controller module and the circuit board. A rotary switch on the EDXE rear panel selects
configuration parameters for the frame, as discussed in Chapter 6 of this manual.

Figure 3-5 DXE Frame Rear Panel Connections
Frame Controller Ethernet Port There are two Frame Controller Ethernet Port Connectors (RJ-45)
located on the rear panel of each DXE frame. These are located on the lower edge of each side of the
frame rear panel. When viewed from the rear of the frame the right-hand connector, labeled
ETHERNET CTRL “A,” is the primary frame controller Ethernet port and the left-hand connector,
labeled ETHERNET CTRL “B,” is the secondary frame controller Ethernet port. Each frame
controller Ethernet port connector is dedicated to a particular power supply/controller module slot: the
Primary Port connector associates to module slot 1 (Refer to Figure 3-5) and the Secondary Port
connector associates to module slot 2.
In a non-redundant system with a single frame controller, install the power supply/PERC1500 module in
slot 1 and use the Ethernet Ctrl “A” port connector to connect the DXE to the facility local area network
(LAN) or closed-loop Ethernet interface for the router system. If a second (redundant) frame controller
is installed, use the Ethernet Ctrl “B” port connector to connect it to the LAN or to the closed
communication loop through an external Ethernet switch. In a redundant control system installation
each frame controller must have a direct connection to an Ethernet hub.
I/O Frame Ports There are 24 I/O Frame Port Connectors (RJ-45) located on the rear panel of every
EDXE frame – positioned as two groups of 12 connectors each. These connector groups are labeled 1
thru 12 and 13 thru 24, and are used to interface the EDXE frame with up to 24 signal frames through
the TDM bus. In most installations, signal frames will be attached to the EDXE I/O frame port
connectors in numerical sequence, beginning with I/O port 1. Connecting signal frames to an EDXE is
discussed further in Chapters 4 and 5 of this guide.
EDXE Links Located in the center of the rear panel are four fiber optic cable connectors denoted as
EDXE Links. These connectors are labeled A thru D and are used to interconnect EDXE frames in
expanded Enterprise DRS systems requiring more than one EDXE. All EDXE to EDXE connections are
made using LC to LC duplex fiber optic cable.

Sync Reference Connectors The EDXE rear panel contains a pair of BNC connectors, labeled SYNC,
for attaching a sync reference signal source to the audio router. Either connector may be used for signal
input, and the remaining connector used as a looping output for the signal if you wish to daisy-chain the
signal source to other equipment. If the EDXE is the last, or only, piece of equipment in the chain, a
terminator must be installed on the unused BNC connector.
Power Cord Connector Access Access port for attaching power cord directly to power supply portion
of controller module. Each power supply carries its own dedicated power receptacle. Input power is not
bussed between modules. When two power supplies are used (for redundancy) a separate power cord
must be attached to each receptacle through its access port. Each access port is equipped with a harness
device for the input power cord. The harness secures the cord to help prevent accidentally disconnecting
the frame from its power source.
3.7
POWER SUPPLY/CONTROLLER MODULES
Two variations of Power Supply/Controller Modules are used in DRS system architecture. Both supplies
are constructed as a modular unit that slides into either of the two available slots in the chassis frame. In
redundant power supply applications, a power supply/controller module is used in both slots of a chassis
frame.
A typical power supply/controller module is shown in Figure 3-6. The two modules are distinctly
different in controller function, even though the power supply portion is identical in function and
circuitry with both modules. They are identified as follows:
Figure 3-6 Power Supply/Controller Module (Typical)
Power Supply/PERC1500 Controller Module - This module contains power supply circuitry that
provides power to all frame components, a pair of fans used to circulate cooling air through the chassis
frame and control circuitry that monitors operation and reports status of the on-board cooling fans. In
addition it contains the PERC1500 Frame Controller circuitry used to communicate with the external
system controller over an Ethernet link. At least one module of this type is required in every EDXE
frame.
Power Supply/Fan Controller Module - This module contains power supply circuitry, a pair of fans
used to circulate cooling air through the chassis frame, and control circuitry that monitors operation and
reports status of the on-board cooling fans. This module is typically used in signal frames.

Chapter 4 Functional Description
4.1
DRS SYSTEM FUNDAMENTALS
Chapter 3 introduced the various types of frames in Enterprise DRS system architecture and provided a
brief introduction to the function of each frame. In order to interconnect these various components into a
working system a few key principles of system operation need to be discussed.
Unlike a traditional crosspoint matrix router where signal connectors are contained in a single chassis
and input and output cables must terminate at the same hardware unit, the DRS distributes input and
output connections over frames configured as signal blocks of various size and type, all interconnected
through a data exchange engine (EDXE) frame. Each input block contains circuitry necessary to convert
input signals to digital data, apply any desired DSP functions to audio signals and “packetize” the digital
data into a serial stream, the TDM bus, containing high speed samplings of every input signal in the
channel block. This data stream is routed to an interface port of the EDXE.
The EDXE frame performs the actual “routing” function by disassembling incoming data packets to
extract signal data for each input channel, constructing outgoing packets containing desired signal data
for specific output channels, and routing each outgoing data packet to the frame and channel block
containing the specific output channel. In the output frame, the TDM bus data is extracted, processed,
converted to the native signal format of the output block and routed to output connectors.
4.1.1 SINGLE EDXE SYSTEM CHANNEL ASSIGNMENTS
Signal frames and the signal channel blocks they contain are “assigned” their I/O channel number range
by the order they are connected to the EDXE I/O frame ports. For example, in a single EDXE system,
the input and output channel range is 1 – 1536; and the signal frame connected to I/O port 1 is assigned
the first 128 channels. Depending on the type and number of blocks in the frame, the channels may be
assigned as inputs 1 – 128, outputs 1 – 128, or inputs 1 – 64 and outputs 1 – 64. The frame connected to
I/O port 2 is assigned the next group of 128 channels, etc. The actual channel numbers assigned can
vary and depend entirely on the type and number of blocks attached to the previous frame port. For
example if port 1 is connected to a block of 128 input signals, and another 128 channel input block is
connected to port 2, the frame controller assigns input channel numbers 129 – 256 to these inputs; but if
a block of 128 output signals is attached to port 2, the frame controller assigns output channel numbers
1 thru 128 to these signals.
Signal frames always have a capacity of 128 channels. As long as the frame supports only input signals
or only output signals, it makes no difference whatsoever if the frame is a single block of 128, or is a
split frame with 64 analog signals and 64 AES signals, the EDXE port still assigns the frame as a range
of 128 input or output channels. If a split frame with one input signal block and one output signal block
is attached to a port, each block is assigned the next sequential range of 64 channel assignments. For
example, assume a frame with 128 input channels is attached to port 1 and a split frame with 64 inputs
and 64 outputs is attached to port 2. The frame on port 2 is assigned inputs 129 – 192 and outputs 1 thru
64. Channel assignments continue in numerical sequence by port until the 1536 input and 1536 output
channel maximum of the EDXE is reached.

March 2014
4.1.2 MULTIPLE EDXE CHANNEL ASSIGNMENTS
DRS installations expanded beyond a capacity of 1536 inputs or 1536 outputs require the use of
additional EDXE frames and their associated signal frames. If an EDXE and its signal frames is loosely
considered as a “complete” router for 1536 inputs and 1536 outputs; then with an expanded system,
each EDXE may be considered as a 1536 X 1536 “building block” of the total system capacity.
Each EDXE frame, and its associated input and output blocks, is called a channel group and assumes
the identity of the numeric channels it processes. In a single EDXE system, the frame is identified as I/O
range 1 – 1536, since this is the channel range a single EDXE would process. In multiple EDXE
installations, the second EDXE is identified as I/O range 1537 – 3072, and the third, fourth and fifth as
I/O range 3073 – 4608, 4609 - 6144 and 6145 – 7680, respectively. The EDXE naming scheme may
seem like a trivial point, but its importance will become clear during the discussion of system hardware
configuration.
Consider an example of a system with two EDXE frames where the first EDXE processes channel group
1 – 1536 and is identified by the nomenclature I/O range 1 – 1536 and the second EDXE processes
channel group 1537 – 3072 and is identified as I/O range 1537 – 3072. The first 128 input and output
signals supported by the second EDXE are assigned channel numbers 1537 – 1664, the second group
would be 1665 – 1792, etc. Just as with the first EDXE, channel numbers are assigned to audio blocks
connected to the I/O frame ports in sequential order; beginning with port 1.
The channel group a specific EDXE processes is assigned to the frame by the setting of the rotary
switch on its rear panel. This is discussed further in Chapter 6.
4.1.3 REDUNDANT FRAME CONTROLLERS AND REDUNDANT EDXE FRAMES
Previous text discussed that each EDXE must contain at least one PERC1500 frame controller, but it
may also contain a secondary controller for redundancy. Also, a given EDXE processes a specific
channel group of 1536 input and 1536 output signal channels, and a redundant EDXE, processing the
same channel group and sharing the same signal frames with the primary EDXE, may be added for
TDM bus processing redundancy. This means that each I/O channel group must have a minimum of one
frame controller, but can have as many as four frame controllers – all configured for the same channel
group and frame-type assignments, as shown in the chart below.
Possible Frame Controller Assignments for any I/O Channel Group
• Primary DXE, Primary Controller
• Primary DXE, Secondary Controller
• Redundant DXE, Primary Controller
• Redundant DXE, Secondary Controller
DXE frame status, as to primary or redundant, is also assigned by the setting of the rotary switch on its
rear panel. This is discussed further in Chapter 6.
4.1.4 BASE IP ADDRESS OF A DRS SYSTEM
Previously, we discussed the interaction between the frame controller(s) contained in an EDXE and the
router system controller, such as a PERC2000. We know that the frame and system controllers
communicate over Ethernet, and that each component on any Ethernet network must be assigned a
unique IP address. IP addresses for all network devices are usually assigned by a facility IT
administrator or network manager.
4-2
ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
Each PERC1500 frame controller in an Enterprise DRS system must have a unique IP address;
therefore, a sequential group of IP addresses should be dedicated to DRS frame controllers on the
network. A fully expanded DRS with total TDM bus and frame controller redundancy would require a
block of 16 sequential IP addresses dedicated to the DRS router system. The numbers in the first three
octets of the address are always identical, such as 192.168.1.xxx; and the number in the fourth octet
determines the unique address for each controller device, such as 192.168.1.001 to 192.168.1.016. With
regard to a DRS installation, the IP address with the sequentially lowest number in the fourth octet
assigned to the router is called the base IP address, and becomes the network name for the entire
Enterprise DRS system, regardless of how many frames or controllers it contains. A unique IP address
for each individual controller in the system is derived at system boot-up by adding a defined address
offset to the assigned base address. The notion of the base IP as the network identity for the entire DRS
system is very important and will become much more important as we discuss expanded and redundant
systems.
4.1.5 INTRODUCTION TO HARDWARE AND ROUTER CONFIGURATION
From previous text, we see that every EDXE frame in a DRS router can be uniquely identified by three
characteristics – the base IP address assigned to the DRS system, the channel group it processes and
whether it is the primary or redundant EDXE frame for the channel group. If the frame is equipped with
redundant frame controllers, they can further be identified as the primary or secondary controller. EDXE
and frame controller identification characteristics play a key role in performing system configuration.
Every PERC1500 frame controller in the system is programmed with the assigned base IP address
in its’ flash memory. On system start-up each frame controller performs a boot-up procedure on its
processor circuitry. As part of initialization, each frame controller reads the setting position of the rotary
switch on the rear panel of the EDXE in which it is installed; and it also determines in which module
slot it is installed. Based on these criteria an individual controller can identify whether it is installed and
initialized as the primary or secondary controller in the primary or redundant EDXE frame, and it
determines the channel group it is processing based on the setting of the rotary switch. An individual
controller also determines and assumes it own unique operating IP address by adding an offset value,
defined by its identity determined in the previous steps, to the programmed base IP address of the
system.
On completion of boot-up, every frame controller in the system assumes an individual identity based on
the following characteristics:
•
•
•
•
Its unique IP address on the network
Channel group it processes
Whether it is installed in the primary or redundant EDXE frame of the channel group
Whether it is functioning as the primary or secondary controller in the frame
In Paragraph 4.1.3 we discussed that each channel group must have a minimum of one frame controller,
but can have as many as four, if the system is equipped with full control and TDM bus redundancy.
Since a channel group consists of one (or two) EDXE frame(s) connected to the primary (or primary and
redundant) TDM bus connectors of the signal frames, then any controller in the group is a candidate to
potentially assume control of the channel blocks; and therefore all controllers for the channel group
must be programmed with the same data as to the type of frames and channel blocks connected to the
EDXE I/O ports. This is done through the hardware configuration file.
4-3
ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
During installation of an Enterprise DRS system there are two configuration operations that must be
performed – hardware and router configuration. Hardware configuration defines the number and type
of channel blocks attached to each EDXE frame in the system. It is performed through the EDXE Frame
Port Configuration Screen of Cattrax, and the resulting configuration file is downloaded to the frame
controllers. Router configuration is where the actual signal switching functions, such as signal
input/output assignments, signal names and aliases, switching levels, components and other special
router functions are written as a configuration file and downloaded to the system controller.
These are two very distinct operations with an Enterprise DRS installation, although both are performed
through screens of the Cattrax system control application. Hardware configuration is performed from
Cattrax simultaneously for all frame controllers in a specific channel group, whether there is one
controller or four controllers. When you perform hardware configuration the frame type, signal type and
signal format attached to each EDXE I/O port is entered; and the input/output channel number range for
the audio blocks in each frame is calculated and assigned by the configuration application. Once all the
audio block and frame parameters for the channel group are entered on the configuration screen, the
configuration file is downloaded simultaneously to all frame controllers in the channel group.
The procedure for generating a hardware configuration file is presented in Chapter 7 of this guide. For
purposes of this discussion, you need to be aware that every frame controller in the system assumes a
unique personality based on the identity it determines and assumes on boot-up and the hardware
configuration file downloaded to it from Cattrax. Hardware configuration data for a specific channel
group is written to flash memory on each individual frame controller module in the group, and is
retained by the module until it is overwritten by another configuration file.
4.2
SYSTEM CONFIGURATION AND EXPANSION
4.2.1 BASIC SYSTEM CONFIGURATION
Through the remainder of this chapter, the term audio frame, or
frames, is used in the configuration examples. Time code frames are
interfaced to other system components in the same manner as an audio
frame and can be considered as interchangeable in these examples, with
the following exceptions: Time code frames support a maximum of 64
physical input or output channels, regardless of rear panel connector
type. Split frames are not available for time code routing.
Basic System Configuration Using Dedicated 128 Channel Audio Frames
Audio signals enter and leave the router system through signal blocks and the EDXE receives, processes
and distributes serial data between audio blocks. A simplified block diagram of a basic router
configuration is shown in Figure 4-1. In this illustration, frame 1 provides a block of 128 input channels,
and frame 2 provides a block of 128 output channels for one specific signal format.

ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
Figure 4-1 Basic DRS Router Configuration
For this example, assume both signal frames contain circuit boards for AES audio signals. Each frame
must be connected to the EDXE I/O frame port connectors in numerical sequence by the range of signal
channels you wish to assign to it, beginning with frame port 1. In our example configuration, the frame
containing a dedicated input channel block for AES signals assigned as inputs 1 thru 128 is connected to
frame port 1. Each frame port can interface with up to 128 channels from a single audio frame, so this
frame fills the entire capacity of port 1 with input signals. In similar fashion, the frame containing a
dedicated output channel block for AES signals assigned as outputs 1 thru 128 is connected to frame
port 2. This frame fills the entire capacity of port 2 with output signals.
When configuring an Enterprise DRS system, regardless of signal handling capacity, number of signal
frames, or number of EDXE frames, a hardware configuration file must be generated and downloaded to
the frame controller(s) contained in the EDXE, as discussed in Paragraph 4.1.5.
Hardware configuration is executed through the DRS Port Configuration Screen of Cattrax; and the
procedure for generating a hardware configuration file is presented in Chapter 7 of this manual.
However, in order to better understand the concept of assignable frame ports, we need to look at a few
of the columns present on this screen. An example screen showing configuration for the basic system
just discussed is shown in Figure 4-2.

Figure 4-2 Example EDXE Port Configuration Screen
The DXE (channel group) being configured is identified at the top of the configuration box by the base
IP address of the DRS system and the numerical I/O range of the channel group. In this example, we are
configuring I/O ports for the system at IP address 10.100.43.20 and the DXE that processes channel
group 1 thru 1536.
Notice from the figure that DXE frame ports 1 thru 24 are listed vertically on the left side of the
configuration box. The next column displays the audio block by signal type and format supported by the
circuit board installed in the signal frame attached to the indicated port. The user may select and enter,
or modify, the type of audio block connected to the port. The next two columns indicate the numerical
range of input and output signal channels supported by the audio block. The user does not select or enter
the channel numbering sequence. The sequence is automatically assigned by the software application
beginning with port 1 and increments based on the number of input and output channels supported by
the signal frame interfaced to the I/O port, until the maximum of 1536 input and output channels is
reached. Once 1536 input channels are assigned, regardless of the frame port number, the control
software does not allow any more frames with input channels to be configured. Likewise, when 1536
output channels are assigned, no more output channels may be configured. The remaining columns are
discussed in later text.
Operationally, it would make no difference whatsoever if the output block were connected to frame port
1 and the input block to port 2 – since both are the first numerical blocks of each signal type. An
example Cattrax configuration screen showing this connection is shown by Figure 4-3.

Figure 4-3 Alternative EDXE Port Configuration
Expanding on this basic configuration, suppose a second input and output block were added to increase
the channel capacity of the system to 256 inputs and 256 outputs, as shown in Figure 4-4. In this
application the blocks in frames 1 and 2 are connected to the DXE just as in the previous example, with
port 1 processing inputs 1 thru 128 and port 2 processing outputs 1 thru 128. Frames three and four
connect to the next two DXE frame ports in numerical sequence as shown in the previous figures.
Using this same principle of adding and configuring audio frames and blocks in numerical sequence, the
single DXE system can be expanded to a maximum configuration of 1536 inputs and 1536 outputs.

System Configuration using Split Frames
Split audio frames, just as dedicated frames, process 128 audio channels. In a split frame, however,
these channels are split into 2 blocks of 64 channels each.
Figure 4-5 is a simplified block diagram of a system configured using one split input frame, one split
output frame and an EDXE. This configuration allows routing a mix of analog and AES signals through
the same frame. Figure 4-6 shows the Cattrax configuration screen for this split frame system. Notice
that the configured board type entry identifies the audio blocks as being split analog/AES inputs or
outputs, but the channel numbering indicates a port capacity of 128 total inputs or 128 total outputs, just
as with a dedicated frame. In the case of both frames, the first 64 channel block (1 – 64) processes
analog signals and the second block (65 – 128) processes AES digital audio signals.

One of the most versatile applications for split frames allows a single audio frame to support both input
and output signal blocks. As an example, consider a two audio frame system for AES signals - each
frame with a block of 64 input signals and a block of 64 output signals. As shown in Figure 4-7, the
audio frame identified as frame 1 is assigned audio input channels 1 through 64 and audio output
channels 1 through 64. Frame 2 is assigned audio input channels 65 through 128 and audio output
channels 65 through 128.

block diagram of a DRS system with one dedicated input frame, one dedicated output frame and two
split input/output frames. The Cattrax configuration screen for this example system is shown in Figure
4-10.

Notice in Figure 4-10 that the numerical sequence of audio channels increments in blocks of 128 or 64
depending on which frame type the port is configured for. As frames are added to the DXE ports, this
numbering sequence will continue until a maximum of 1536 inputs or 1536 outputs is reached.
Unused inputs or outputs in a channel block can not be re-assigned. For example if only 80 of the 128
input channels of frame 1 are used, the next block of input channels on frame 3 still begins with channel
number 129. Channels 81 thru 128 are available on frame 1 for future use. Likewise, if only 40 of the 64
input channels of frame 3 are used input signals to frame 4 still begin at 193, etc.
SYSTEM CONTROL AND SYNC CONNECTIONS
Figure 4-11 illustrates system control and sync connections for a single EDXE. For simplicity, signal
frames are not shown in this illustration.
The single EDXE frame must have a Power Supply/PERC1500 Controller Module (Primary Controller)
installed in module slot 1. Communication between the frame controller and the system controller is
over an Ethernet connection either in closed-loop communication with the system controller or over the
facility local area network (LAN).
Each EDXE frame in the DRS Routing System must be connected to an in-house timing
synchronization reference signal. Loop-thru BNC connectors for sync reference input and output are
provided on the rear panel of every EDXE. Sync may be routed in a daisy-chain configuration through
the EDXE to another piece of equipment, or the chain terminated at the second BNC with a 75 Ohm
terminator. Remember, if the EDXE frame is the only, or the last, piece of equipment on the chain the
open connector on the rear panel pair must be fitted with a 75 Ohm terminator.

Even in the most basic configuration, it is possible to have full power supply and controller redundancy
simply by installing a second power supply/controller module in the secondary module slot of all system
frames. Audio frames should have a second Power Supply/Fan Controller Module installed; and each
EDXE frame must have a second Power Supply/PERC1500 Module installed in module slot 2. As
shown in Figure 4-12, an Ethernet switch is used to provide a direct network connection to each frame
controller module. When a second controller is installed in a EDXE, the IP address of the second
controller is automatically assigned by the frame controller circuitry as determined by the setting
position of the rotary switch.
Figure 4-12 Single EDXE with Redundant Power & Controller
With both controller types, several operating parameters of each power supply module in frames with
redundant power capability are constantly monitored for status. Should a failure of the active power
supply ever occur, the standby supply automatically and seamlessly becomes the active supply for the
frame.
In addition to power redundancy, EDXE frames equipped with two Power Supply/PERC 1500 modules
also operate with redundant frame controller capability whereby one of the modules is always acting as
the “active” controller, while the second module assumes the role of “standby” controller. Should errors
occur with the active controller, or if an operator manually initiates a controller changeover command,
the standby controller assumes active control of the frame, and the previously active module becomes
the standby controller.
By installing a second TDM bus interconnection using the second TDM bus port on each signal frame
and an additional EDXE frame to perform exchange of the redundant bus data, a second TDM bus is
established. Should either TDM bus connection between frames be broken or data become corrupted,
the second (redundant) bus will keep the system fully functional without interruption of audio signals.
The process of adding a second EDXE to a channel group is identical to adding a second DXE to a
channel group with a traditional DRS router. Refer to the DRS Technical Manual for further
information.

4.2.2 SYSTEM EXPANSION
It is possible to expand either the input or output capacity, or both, of the EDRS system, up to a
maximum configuration of 7680 x 7680. Expanded systems use multiple signal frames and one or more
EDXE frames. Any combination of analog and digital channel blocks is allowed in an expanded system.
Single EDXE Frame System An example of a 1536 input x 1536 output expanded system using 24
split I/O frames and a single EDXE frame is represented in the chart below. Analog audio and AES
digital audio sources may be mixed within an expanded system, and mixed within audio frames using
split frames. Audio frames are identified as frames 1 thru 24, and each provides a block of 64 input
channels and a block of 64 output channels. I/O channels are assigned to audio frames in the following
numerical sequence:

Publication 81-9059-0699-0, Rev. B
March 2014
Multiple DXE System Systems requiring greater than a single channel group of 1536 inputs or 1536
outputs are configured using two or more EDXE frames and the required number of audio frames to
provide the desired I/O capacity. Any number of audio frames may be used, up to the system maximum
of 120 frames, providing up to 7680 input and 7680 output channels. Since each EDXE supports up to
24 signal frames - up to 5 primary DXE and 5 redundant DXE frames may be used in a system to link
the signal frames.
The previous section introduced and discussed system expansion for a 1536 X 1536 router using 24
audio frames and a single EDXE; and interconnecting the I/O frames to the EDXE in an ascending
numerical sequence. Building a system greater than 1536 X 1536 expands the same principle and is
accomplished by interconnecting EDXE channel groups to one another in an ascending numerical
sequence, using fiber optic cable.
Remember that an EDXE frame and its associated signal frames together form a channel group, and the
channel group assumes the nomenclature of the I/O channel range it contains. If each channel group is
considered a 1536 input by 1536 output “building block” of the overall expanded system, then in an
expanded system the EDXE frames process the following input and output channel groups:
DXE
1
2
3
4
5
System Channel Groups
Inputs
Outputs
1 - 1536
1 - 1536
1537 – 3072

3073 – 4608
3073 – 4608

6145 – 7680
6145 – 7680
Group Nomenclature
I/O Range 1 - 1536
I/O Range 1537 – 3072
I/O Range 3073 – 4608
I/O Range 4609 – 6144
I/O Range 6145 – 7680
Signal blocks are interconnected to each EDXE in the system in exactly the same way as for a single
EDXE configuration. Each EDXE, along with its input blocks and output blocks, is then interconnected
as a channel group with all the other EDXE frames (channel groups) in the system by fiber optic links.
Just as with audio blocks, unused input or output channels in a channel group can not be re-assigned.
For example if only 1400 of the 1536 input or output channels of group I/O Range 1 -1536 are used, the
next block of audio channels in group I/O Range 1537 - 3072 still begins with channel number 1537 for
both inputs and outputs. Channels 1401 thru 1536 are available in group I/O Range 1 - 1536 for future
use.
EDXE frames are interconnected via the EDXE Links connectors (fiber optic) labeled EDXE 1 thru
EDXE 4 located along the top edge of each EDXE rear panel. Just as with DXE frames in a traditional
DRS installation, each EDXE frame is interconnected with other EDXE frames in the system using a
“star” networking arrangement whereby each frame has a direct connection with every other frame.
More information on proper cabling of a multiple DXE system, and a hook-up table, is presented in
Chapter 5 of this manual.

Chapter 5 Installation
5.1
MOUNT EACH ROUTER FRAME IN AN EQUIPMENT RACK
Make sure the frame power cords are disconnected from the power source
before installing the frame into an equipment rack.
Fans that are mounted inside of this equipment provide forced-air cooling. Do
not block airflow around these fans.
All frames comprising an EDRS router system are designed for installation in a standard 19" equipment
rack. Provide sufficient space behind the equipment racks to allow for control, signal, interconnect and
power cables; and around all sides for cooling. Use all chassis mounting holes, and tighten mounting
hardware securely by using the rack equipment manufacturer’s suggested torque settings.
Installation of signal frames in an EDRS system is identical to a traditional DRS router. Refer to the
DRS Technical Manual for more information and detailed frame installation procedures.
Every EDRS chassis frame is shipped with a Rear Rack Rail Kit. It is important that this kit be installed
as part of the mounting procedure for the frame. Refer to the DRS Technical Manual for more
information and detailed installation procedures.
5.2
CONNECT EQUIPMENT CABLES
Use the following guidelines when connecting equipment cables:
Install equipment in rack before connecting cables.
Relieve strain on all cables to prevent connector separation.
To the greatest extent possible, separate control, signal, and power cables to minimize crosstalk and
interference.
Once each system frame is installed in an equipment rack, associated system connections can be
completed. Order of completion of installation steps is not critical, however, DO NOT apply power to a
frame until all signal, sync, TDM bus, fiber optic and Ethernet network cables have been installed and
their connections verified for proper placement and accuracy.
PESA recommends that you create a chart or list of signals attached to router connectors identifying the
source and destination of the signal, cable number (or other identification designation) and router
channel number assigned to the signal. When connecting cabling with BNC connectors, it’s a good idea
to make a sketch of the rear panel of every audio frame equipped with BNC I/O connectors and note
cable numbers (or other identifier) attached to each I/O connector. When connecting cabling with
ELCO/EDAC or 6-pin detachable connectors, PESA recommends that you make a sketch or a pin
layout table for each connector identifying connector number, signal source and destination, cable
numbers (or other identifier) attached to each set of I/O pins and the router channel number associated
5-1
ENTERPRISE DRS AUDIO ROUTING SYSTEM

with each cable. Prepare this sketch or table BEFORE attaching wires to connector blocks or male
mating plugs, and use it as a reference guide when performing connector assembly. Carefully follow
connector pin-out data provided in this manual when assembling connectors to prevent inadvertent
signal swapping. If at all possible, use a continuity measurement device to verify cable connections
before attaching mating connectors to DRS rear panel connectors. Retain all of your sketches, cabling
diagrams and connection lists, and keep it with your other DRS documentation for future reference.
Use the following guide to insure that all connections are made properly and that power, system
interconnect and signal cables are correctly installed.
1. Connect an external sync source to the Sync Reference Input (REF) of each EDXE Frame using
75 Ohm coaxial cable such as Belden 8281, or equivalent. Be sure to properly terminate external
sync sources into a 75Ω terminator.
2. If using shell connectors such as the ELCO/EDAC or 6-pin, prepare each connector with its
associated input or output signals using connector pin-out data provided in the following
paragraphs. Installation will be much smoother if all connectors intended to mate with rear panel
connectors on DRS I/O frames are pre-wired and tested. If possible, use an Ohmmeter or audible
signal tracing device to verify continuity of each connection prior to attaching the external
connector to the DRS system.
3. When installing cabling between various frames of the DRS system, use high quality CAT5E
cable for interconnecting the TDM bus between frames. Use high quality LC to LC duplex fiber
optic cable for interconnecting EDXE frames in an expanded system.
4. You must configure each EDXE frame, using PESA’s Cattrax, for the signal frames attached to its
I/O frame ports. For more information on I/O frame ports and configuration, refer to the system
configuration discussion presented in Chapter 7 of this manual.
5. Before the EDRS system can be used to make signal switches, a router configuration file must be
loaded into the system controller. This file is generated using the router control application and
contains I/O signal configuration data, level and component assignments and all operational data
for the EDRS audio router as well as all other switching components of the installation.
5.3
CONNECTOR PIN-OUT DATA – INPUT OR OUTPUT FRAMES WITH 128 CHANNEL DEDICATED
SIGNAL BLOCK
Each 128 channel, dedicated signal frame in a DRS system is configured with a rear panel equipped
with one of the connector types listed below. The type of rear panel used is dependent on the type of
signal connected and type of connector used in the installation. In the following paragraphs, each type of
connector is illustrated and pin-out data is provided as a guide when wiring mating connectors to
interconnect with the DRS frame.

Publication 81-9059-0699-0, Rev. B
March 2014
Each AES input or output channel contains a pair of audio signals, therefore the full 128 channel
capacity of the signal frame is realized with 64 AES audio ports. In the case of the BNC rear panel there
are 64 physical connectors for I/O and all inputs or outputs are AC coupled to router circuitry. With the
6-pin and ELCO/EDAC connector rear panel there are actually 128 physical connections (2 sets of
connection pins per connector) for input or output signals. When connecting AES digital audio signals
to the router, this equates to two sets of physical connection pins for each I/O signal. DRS is designed
such that connecting an audio signal to one set of input pins on a connector AC couples the signal to
router circuitry and the other connector pins DC couple the signal. Pin-out charts contained in the
following paragraphs identify how to connect an input source or an output signal for AC or DC
coupling.
5.3.1 BNC CONNECTOR REAR PANEL
There are 64 BNC I/O connectors on a BNC rear panel; each connects to a source of unbalanced AEScompliant digital audio. Figure 5-1 illustrates a BNC rear panel and identifies I/O channel layout.
Carefully follow the connector layout and channel identification chart when completing connections to
the DRS router to prevent inadvertent signal swapping.
Channel pairs of each AES input signal applied to a BNC connector are de-muxed and each individual
audio channel is assigned a source number through the router.
Likewise, the two router destination signals that form the pair for each output channel are multiplexed
into an AES compliant signal available at the BNC connector indicated in the table.
There are 64 BNC connectors on the backplane; however, there are 128
data channels used in the configuration. Since the BNC backplane is used
for connection of AES Audio sources, each input actually carries a pair of
audio signals.

When connecting AES digital audio inputs and outputs to the router, the 128 input connections equate to
two physical connection points for each digital audio signal. One input allows input sources or output

Wiring errors within connectors can be both frustrating and time consuming. Carefully check pin-out
and I/O channel data provided here and verify proper cabling and connector hook-up BEFORE
completing connection to the audio frame.
5.3.3 6-PIN DETACHABLE CONNECTOR REAR PANEL
There are 64 6-Pin I/O connectors on the rear panel; each connector provides 2 physical input or output
connections for a total of 128 I/O connections on a rear panel. Figure 5-5 illustrates the 6-pin connector
rear panel and shows in detail the orientation of rear panel connectors and pin-out connections of mating
plugs.
The mating plug used with the on-board connectors is a solder-less type and uses a spring clamp to
securely hold input or output cable wires. Connections are made by inserting the wire end into the round
receptacle on the plug. The small square hole beside each wire receptacle contains a spring release that
loosens the clamp and allows the wire to be removed from its associated receptacle. To remove a wire,
simply insert the blade of a small flat tip screwdriver into the release hole adjacent to the receptacle
containing the wire you wish to remove, and gently pull the wire from the receptacle.

ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
When connecting AES digital audio inputs and outputs to the router, the 128 input connections equate to
two physical connection points for each digital audio signal. One input allows input sources or output
signals to be AC coupled to the router and the other allows signals to be DC coupled.
When connecting analog input or output signals each of the 128 input connections is used for a separate
single-channel, balanced audio input or output. Analog Audio Outputs MUST be connected to a highimpedance load, >10K Ohms. When wiring UNBALANCED analog output signals to external loads,
NEVER connect the negative (-) output terminal to any external connection point or to ground. The
negative terminal MUST be left floating.
Connector orientation and pin identification diagrams are provided by Figure 5-5. Figure 5-6 provides a
detailed view of I/O connector numbering layout and Figure 5-7 illustrates channel I/O pin arrangement
for a typical 6-pin connector. Table 5-2 is a detailed I/O channel pin-out chart.

CONNECTOR PIN-OUT DATA – SPLIT INPUT OR OUTPUT AUDIO FRAMES
Split frames, regardless of connector mix, are configured as two blocks of 64 input or output channels
with connectors for each channel block, referred to as a connector bank. Connectors may be all of the
same type, such as two banks of BNCs, or may be a mix of BNC and either ELCO/EDAC or 6-pin
detachable. Connectors available for split frames are the same as those used with dedicated frames and
are compatible with the signal types identified in paragraph 3.2.
Connector population for a split frame rear panel is dependent on the type of signals connected and type
of connectors used in the installation. In the following paragraphs, each rear panel variant is illustrated
and pin-out data is provided as a guide when wiring mating connectors to interconnect with the DRS
frame. Split frames are available where both connector banks are inputs or outputs; or where one bank is
for input signals and the other is for output signals. Each split frame rear panel is shipped from the
factory with a rear panel label identifying each connector bank as input connections or output
connections. Regardless of whether the connector bank is used for input signals or output signals, the
connector pin-outs and channel number assignments presented in the following paragraphs are the same.
5.4.1 SPLIT FRAME BNC CONNECTOR REAR PANEL
Figure 5-8 illustrates a split frame BNC rear panel and identifies I/O channel layout. Carefully follow
the connector layout and channel identification chart when completing connections to the DRS router to
prevent inadvertent signal swapping.
There are 32 BNC connectors in each connector bank on the rear panel
used for connection of AES audio sources. Since each AES audio signal
carries a pair of monaural audio channels, each bank of 32 BNC connectors
actually carries 64 channels, for a frame total of 64 input channels and 64
output channels.

5.4.2 SPLIT FRAME ELCO/EDAC CONNECTOR REAR PANEL
There are four ELCO/EDAC 120 pin connectors on the split frame rear panel, divided into two banks of
two connectors, each providing 32 input or output connections, for a total of 64 connections per bank.
Figure 5-9 illustrates the split frame ELCO/EDAC rear panel and identifies I/O connection layout.
Connector pins associated with the first numerical input of each connector (1 or 33) are located on lower
left side of connector.
ELCO/EDAC rear panels are manufactured using EDAC Part Number
516-120-520-202 connectors from the 516 Rack and Panel Connector Series.
Choose mating connectors from this series (or equivalent) that best fit your
installation. Mating connectors are available in many styles from the
manufacturer and may be viewed at their website: www.edac.net
When connecting AES digital audio inputs and outputs to the router, the 128 input connections equate to
two physical connection points for each digital audio signal. One input allows input sources or output
signals to be AC coupled to the router and the other allows signals to be DC coupled.
When connecting analog input or output signals each set of connector pins is used for a separate singlechannel, balanced audio input or output. Analog Audio Outputs MUST be connected to a highimpedance load, >10K Ohms. When wiring UNBALANCED analog output signals to external loads,
NEVER connect the negative (-) output terminal to any external connection point or to ground. The
negative terminal MUST be left floating.
Detailed pin-out diagrams are provided by Figure 5-3 and Figure 5-4; and a pin identification chart is
provided by Table 5-3.
Carefully follow connector pin-out data provided by Table 5-3 when assembling connector blocks to
prevent inadvertent signal swapping. If at all possible, use a continuity measurement device to verify
cable connections before attaching mating connectors to DRS rear panel connectors.

5.4.3 SPLIT FRAME 6-PIN DETACHABLE CONNECTOR REAR PANEL
There are 64 6-Pin I/O connectors on a rear panel, divided into two banks of 32 connectors per bank,
each of which provides 2 physical input or output connections for a total of 64 I/O connections per
bank. Figure 5-10 illustrates the split frame 6-pin connector rear panel and identifies connector layout.
The mating plug used with the rear panel connectors is a solder-less type and uses a spring clamp to
securely hold input or output cable wires. Connections are made by inserting the wire end into the round
receptacle on the plug. The small square hole beside each wire receptacle contains a spring release that
loosens the clamp and allows the wire to be removed from its associated receptacle. To remove a wire,
simply insert the blade of a small flat tip screwdriver into the release hole adjacent to the receptacle
containing the wire you wish to remove, and gently pull the wire from the receptacle.
AES digital channels contain a pair of audio signals, therefore each AES signal cable is connected to
only one set of connector pins on each 6-pin connector. Thus, the 64 input connections of each bank
allow for two physical connection points in each physical connector for each AES digital audio signal.
One set of pins allows input sources or output signals to be AC coupled to the router and the other set
allows signals to be DC coupled. The AES Digital column in the pin-out chart identifies the pins that
provide DC coupling to the signal and the pins that provide AC coupling; you may use either set of
connector pins, depending on how you wish to connect the signal to the router.
When connecting analog input or output signals each set of connector pins is used for a separate singlechannel, balanced audio input or output. Analog Audio Outputs MUST be connected to a highimpedance load, >10K Ohms. When wiring UNBALANCED analog output signals to external loads,
NEVER connect the negative (-) output terminal to any external connection point or to ground. The
negative terminal MUST be left floating.
Depending on the system configuration, each connector bank may support input or output signals. The
following connector pin-out data is applicable for either signal type. Carefully follow pin-out data
provided in this text when assembling male mating plug connectors to prevent inadvertent signal
swapping. If at all possible, use a continuity measurement device to verify cable connections before
attaching mating connectors to DRS rear panel connectors.
Connector orientation and pin identification diagrams are provided by Figure 5-5. Figure 5-10 provides
a detailed view of I/O connector numbering layout for the split rear panel and Figure 5-7 illustrates
channel I/O pin arrangement for a typical 6-pin connector. Table 5-4 is a detailed I/O channel pin-out
chart.

5.4.4 SPLIT FRAME MIXED ELCO/EDAC AND BNC CONNECTOR REAR PANEL
There are two ELCO/EDAC I/O connectors and 32 BNC I/O connectors on the mixed rear panel,
divided into two banks of 64 channels. Figure 5-11 illustrates the mixed rear panel and identifies I/O
connector layout. Carefully follow the connector layout and channel identification when completing
connections to the DRS router to prevent inadvertent signal swapping.

March 2014
ELCO/EDAC Connector Wiring
Figure 5-11 illustrates the mixed rear panel and identifies I/O connection layout. The bank 1
ELCO/EDAC connectors follow the same pin-outs and channel numbering as bank 1 connectors 1 and 2
provided in Table 5-3.
ELCO/EDAC rear panels are manufactured using EDAC Part Number
516-120-520-202 connectors from the 516 Rack and Panel Connector Series.
Choose mating connectors from this series (or equivalent) that best fit your
installation. Mating connectors are available in many styles from the
manufacturer and may be viewed at their website: www.edac.net
When connecting AES digital audio inputs and outputs to the router, the 64 input connections of each
bank equate to two physical connection points for each digital audio signal. One input allows input
sources or output signals to be AC coupled to the router and the other allows signals to be DC coupled.
When connecting analog input or output signals each of the 64 input connections is used for a separate
single-channel, balanced audio input or output. Detailed pin-out diagrams are provided by Figure 5-3
and Figure 5-4.
Carefully follow connector pin-out data provided by Table 5-3 when assembling connector blocks to
prevent inadvertent signal swapping. If at all possible, use a continuity measurement device to verify
cable connections before attaching mating connectors to DRS rear panel connectors.
BNC Connector Cabling
Follow the connector layout diagram, Figure 5-11, and the channel assignment chart, Table 5-5, when
attaching cables to the BNC connectors on the mixed rear panel.
There are 32 BNC connectors for connector bank 2 on the mixed rear panel,
however, there are 64 data channels used in the configuration. Since BNC
connectors are used for connection of AES Audio sources, each input
actually carries a pair of audio signals.

ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
The mating plug used with the on-board connectors is a solder-less type and uses a spring clamp to
securely hold input or output cable wires. Connections are made by inserting the wire end into the round
receptacle on the plug. The small square hole beside each wire receptacle contains a spring release that
loosens the clamp and allows the wire to be removed from its associated receptacle. To remove a wire,
simply insert the blade of a small flat tip screwdriver into the release hole adjacent to the receptacle
containing the wire you wish to remove, and gently pull the wire from the receptacle.
When connecting AES digital audio inputs and outputs to the router, the 64 input connections equate to
two physical connection points for each digital audio signal. One input allows input sources or output
signals to be AC coupled to the router and the other allows signals to be DC coupled. When connecting
analog input or output signals each of the 64 input connections is used for a separate single-channel,
balanced audio input or output.
Carefully follow connector pin-out data provided in this text when assembling male mating plug
connectors to prevent inadvertent signal swapping. If at all possible, use a continuity measurement
device to verify cable connections before attaching mating connectors to DRS rear panel connectors.
Connector orientation and pin identification diagrams are provided by Figure 5-5. Figure 5-12 provides
a detailed view of I/O connector numbering layout for the mixed rear panel and Figure 5-7 illustrates
channel I/O pin arrangement for a typical 6-pin connector. Table 5-4 is a detailed I/O channel pin-out
chart.
BNC Connector Cabling
Follow the connector layout diagram, Figure 5-12, and the channel assignment chart, Table 5-5, when
attaching cables to the BNC connectors on the mixed rear panel.
There are 32 BNC connectors for connector bank 2 on the mixed rear panel,
however, there are 64 data channels used in the configuration. Since BNC
connectors are used for connection of AES Audio sources, each input
actually carries a pair of audio signals.
5.5
CONNECTOR PIN-OUT DATA – TIME CODE FRAMES
Time code frames, regardless of connector type, are configured as a single, dedicated input or output
block of 64 physical input or output channels. Each time code channel is routed as two signals, so 64
physical inputs equate to 128 routing signals; and therefore the single, dedicated block fills the capacity
of the frame and the DXE port to which it is attached. Time code frames may be fitted with any of the
connector-type rear panels used for dedicated audio frames; however, connection pin-outs for the
ELCO/EDAC and 6-pin detachable connector rear panels are different than with audio signals.
DRS rear panels, with the exception of the BNC rear panel, provide 128 physical input connections,
only 64 of which are used with a time code input or output frame. Both single-ended and differential
time code sources may be connected to a router with ELCCO/EDAC or 6-pin detachable connector rear
panels. Pin-out charts contained in the following paragraphs identify how to connect input sources and
output channels for single-ended or differential hook-up schemes. In the case of a BNC rear panel, all
inputs and outputs are connected as single-ended sources.

5.5.1 BNC CONNECTOR REAR PANEL FOR TIME CODE
There are 64 BNC I/O connectors on a rear panel; each connects to a source of single-ended time code.
BNC rear panel I/O channel layout for time code is identical to the audio layout as shown in Figure 5-1.
Carefully follow the connector layout and channel identification chart when completing time code
connections to the DRS router to prevent inadvertent signal swapping.
5.5.2 ELCO/EDAC CONNECTOR REAR PANEL FOR TIME CODE
There are four ELCO/EDAC 120 pin connectors used on a rear panel, each providing 16 input or output
time code connections, for a total of 64 connections. Figure 5-13 illustrates the ELCO/EDAC rear panel
for time code signals and identifies I/O connection layout. Notice that the set of pins associated with the
first numerical input of each connector (1, 33, 65 and 97) is located on lower left side of connector.
ELCO/EDAC rear panels are manufactured using EDAC Part Number
516-120-520-202 connectors from the 516 Rack and Panel Connector Series.
Choose mating connectors from this series (or equivalent) that best fit your
installation. Mating connectors are available in many styles from the
manufacturer and may be viewed at their website: www.edac.net
When connecting time code inputs and outputs to the router, the 64 connections may be single-ended or
differential. Detailed pin-out diagrams are provided by Figure 5-3 and Figure 5-4; and a pin
identification chart is provided by Table 5-6.

5.5.3 6-PIN (WEIDMULLER) CONNECTOR REAR PANEL FOR TIME CODE
There are 64 6-Pin I/O connectors on a 6-pin connector rear panel, each connector provides both singleended or differential connections for a single time code signal for a total of 64 time code I/O
connections on a rear panel. Figure 5-5 illustrates a typical 6-pin connector rear panel and shows in
detail the orientation of rear panel connectors and pin-out connections of mating plugs.
The mating plug used with the on-board connectors is a solder-less type and uses a spring clamp to
securely hold input or output cable wires. Connections are made by inserting the wire end into the round
receptacle on the plug. The small square hole beside each wire receptacle contains a spring release that
loosens the clamp and allows the wire to be removed from its associated receptacle. To remove a wire,
simply insert the blade of a small flat tip screwdriver into the release hole adjacent to the receptacle
containing the wire you wish to remove, and gently pull the wire from the receptacle.
When connecting time code inputs and outputs to the router, the 64 connections may be single-ended or
differential. Connector orientation and pin identification diagrams are provided by Figure 5-5. Figure 56 provides a detailed view of I/O connector numbering layout and Figure 5-7 illustrates channel I/O pin
arrangement for a typical 6-pin connector. Table 5-7 is a detailed I/O channel pin-out chart for time
code signal connection.

DRS INTERCONNECT CABLES
Ethernet Connections and TDM bus interconnects between frames are made using common CAT5x
cable and RJ-45 connectors. Two types of Ethernet cables are commonly available: those that are
“straight-thru” pin-for-pin and “crossover” cables that have transmit leads (TX+ and TX-) and receive
leads (RX+ and RX-) exchanged between the two connector ends according to a specified pin-out
standard. All DRS connections, both TDM bus and Ethernet, can use either type of cable. Auto-detect
circuitry determines the type of cable used and makes proper internal connections accordingly. This
operation is totally transparent and requires no operator input or action.
Pre-assembled Ethernet cables, in various lengths, with connectors attached are readily available from a
number of sources. In some installations it may be necessary, due to routing requirements or other
constraints, to run bulk cable and attach connectors once the cable is in place. PESA recommends that,
unless you have training in proper crimping techniques and the necessary equipment, you purchase preassembled cables if at all possible for your installation
If you do choose to make your own interconnect cables, always use high quality cable and connectors,
use a good crimping tool and follow proper technique when installing connector ends to the cable run.
An improperly installed connector end can seriously degrade performance of the DRS system. For
consistency, PESA recommends that you wire all cables as pin-for-pin “straight-thru” (no TX/RX
crossover) using the EIA/TIA 568B "standard" color code scheme shown in Figure 5-14. Pin numbering
for a standard RJ-45 connector is also provided in Figure 5-14 for reference.

INTRA-SYSTEM CABLING AND CONNECTIONS
From the simplest to the most complex system, each installation requires some degree of intra-system
cabling between the various frames comprising the DRS router. The number and type of intra-system
cables will vary by system and depends on the number of signal frames, number of DXE frames and
whether or not system redundancy is incorporated. Regardless of the number and length of cables
ultimately used for configuration, there are three types of intra-system connections possible for a DRS
installation: TDM data bus, DXE Fiber Optic Links (if used) and Ethernet connection. Each connection
type is identified and discussed in the following paragraphs.
5.7.1 TDM DATA BUS
Installation of TDM data bus configurations for EDRS systems is identical to traditional DRS
installations. Refer to the DRS Technical Manual for further information.
DO NOT CONNECT THE TDM BUS
CONNECTORS TO AN ETHERNET NETWORK!!
Even though the TDM bus connections are made using RJ-45 connectors
and CAT5E cable, they SHOULD NOT attempt to be made through the
facility LAN. The TDM bus operating parameters require dedicated, pointto-point connections, and WILL NOT function over a network!!
5.7.2 EDXE FIBER OPTIC LINKS
When multiple EDXE frames are used in an expanded system, all of the frames must be interconnected
using an optical cabling method analogous to the “star” networking topology. There are a few
constraints on connecting and routing the optical cables. You will obtain best performance and highest
signal integrity by using high quality fiber optic cable for interconnection. Plan your installation by
determining the location of the DXE frames and use the shortest, most direct path possible for running
optical cables between frames.
5-28
ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
You will find it very helpful in installing and working with any fiber optic system to take time to
familiarize yourself with some basic knowledge of optical data transmission principles and fiber optic
cable characteristics. It is not the intent of this manual to provide a tutorial on optical data systems;
however, to insure the best DRS router installation possible there are a few points in dealing with optical
cable that should be discussed:
1. Duplex fiber optic cable with a type LC connector on each end is required for connection of
DXE frames. Duplex cable actually consists of two separate optical conductors in each run of
cable. Since light is not bi-directional, two conductors, transmit and receive, are required for a
two-way communication system. The two conductors attach to DXE rear panel receptacle
connectors.
The Transmit Port from one DXE MUST connect to the receive Port of
another DXE. In order to accomplish this, each duplex cable MUST be
configured as “Cross-Over.”
2. Fiber optic cable, like any other cable, is available in bulk spools of varying lengths without
connectors attached. Be aware that some degree of specialized training, skill and equipment is
required when installing connector ends to fiber optic cable, or when splicing two cable ends
together. In some installations it may be necessary, due to routing requirements or other
constraints, to run bulk cable and attach connectors once the cable is in place. For easier and
quicker installation, pre-assembled fiber optic cables, in various lengths, with connectors
attached are readily available from a number of sources. PESA highly recommends that, unless
you have training in working with optical cable and the necessary equipment, you purchase
pre-assembled cables if at all possible for your installation. If using pre-assembled cabling is
not feasible for your installation, consider procuring the services of a trained fiber technician,
certified for fiber terminations, to install connectors and verify cable continuity before
proceeding with DXE interconnection.
3. One final point on dealing with optical cable - be sure that the optical connectors are clean and
dust free. Each end of a fiber cable connection is fitted with a small lens to direct the light
source. Dust, even small amounts, can greatly degrade performance of an optical data
transmission system. Always keep dust caps on cable connector ends and optical receptacle
connectors when cables are not attached. NEVER touch the end of the optical connector or
receptacle with your bare skin. Grease and dirt, even minute amounts, can seriously degrade
performance of the optics.
The dual conductors of fiber optic cable are usually attached to a connector equipped with two fiber-end
lenses, one for each conductor. This assembly mates to rear panel DXE Link receptacles on the DXE
simply by inserting the connector end into its mating receptacle with very slight pressure. A snap latch
secures the end into the receptacle. To remove cable-end connector from a rear panel receptacle, gently
press the latch tab and pull cable from receptacle. Immediately replace dust caps on the end of each
fiber cable conductor and the DXE connector receptacle.
Multiple DXE frames must be interconnected to one another in a numerical sequence through the DRS
DXE Links connectors, labeled DXE 1 thru DXE 3, located along the top edge of each DXE rear panel.
DXE frames are interconnected with one another in a manner whereby each frame has a direct
connection with every other frame. Proper interconnection of a full capacity system is illustrated in
Figure 5-15. Table 5-8 is a hook-up chart providing quick reference for determining proper DXE to
DXE frame connection.

Interconnecting between the proper EDXE Link Connectors on each frame is critical for proper system
operation. Use the references discussed above when installing fiber interconnect cables to insure that all
cables are attached to the proper connectors. The system will not function properly and troubleshooting
could be a tedious task if these connections are not made correctly.
In planning your installation, consider carefully the placement of EDXE frames and how to route and
dress optical cabling between all frames. As with any wiring effort, using a chart or sketch greatly
simplifies final hook-up once all optical cables are in place. Make notes of cable numbers (or other
identifiers) and the name and number of the rear panel connector to which each cable is attached.
Always retain any installation data for future use should system troubleshooting ever be necessary.

Dust, even small amounts, can greatly degrade performance of an optical
data transmission system. Always keep the dust caps on the cable connector
ends and the optical receptacle connectors when the cables are not attached.
NEVER touch the end of the optical connector or receptacle with your bare
skin. Grease and dirt, even minute amounts, can seriously degrade
performance of the optics.
5.8
PESA CONTROL SYSTEM INSTALLATION
PESA router installations have two major control system components: frame controllers and a system
controller that interface through a communication protocol. A frame controller card is located in every
video routing chassis and every DRS DXE frame; and, as the name implies, is the control component
for functions within the particular frame in which it is installed. In a typical PESA installation, there is
only one system controller, or two for systems with control bus redundancy. The system controller
interfaces with all frame controllers, remote control panels and a host computer. Its function is to
oversee operation of the entire router installation through commands and communication with the
individual frame controllers.
With EDRS systems, PERC1500 (P1500) identifies the frame controller circuitry installed in each
EDXE frame. P1500 uses a 10/100 Ethernet protocol for communication and must be paired with a
PESA system controller, such as the PERC2000, to complete the DRS control system requirements.
Control layout and connection of the P1500 to the system controller is identical to the methods used
with a traditional DRS installation. Refer to the DRS Technical Manual for further information.
5.9
POWER CONNECTIONS
Power for all EDRS system frames is derived from wall receptacles. No special direct wiring or heavy
gauge wire is required for this equipment. There are two power connector access ports, one located on
the upper left-hand side and the other on the upper right-hand side of the rear panel of each EDRS
frame, regardless of frame type. These ports allow access to the power receptacle on the power
supply/controller module located in the slot associated with each. In a non-redundant power or control
system, only one of the slots will have a power supply module installed. Attach the power cord through
the proper access port to the receptacle on the power supply module. Each power supply carries its own
dedicated power receptacle. Input power is not bussed between modules. When two power supplies are
used (for redundancy) a separate power cord must be attached to each receptacle through its access port.
Each access port is equipped with a harness device for the input power cord that secures the cord to
prevent accidentally disconnecting the frame from its power source. To use the harness, slip the groove
on the power cord connector end horizontally into the opening of the harness. In planning your
installation, consider the location of each DRS system frame and how to route and dress power cords
from the power source to each frame.
Connecting the power cord to a source of power immediately applies power to the DRS frame. Do not
apply power for the first time until all signal, intra-system, sync and control connections have been
made and verified.

5.10 INITIAL POWER-UP
Before applying power to the EDRS system for the first time, please take time to go back over your
installation:
•
•
•
•
Check for electrically sound connections, proper connector placement and possible wiring
errors.
Ensure that each EDXE frame has a connection with a source of in-house sync reference and
that each loop-through connector is either daisy-chained to the next unit in the chain, or is
properly terminated into a 75Ohm load.
Check that all circuit cards and power supply/controller modules are securely installed in each
system frame.
Verify settings of the rotary configuration switches on each EDXE rear panel.
There are no power switches on the EDRS frames and each frame is powered-up simply by connecting
the main power cord to a source of primary power. Systems with redundant power supply/controller
modules have two main power cords per frame, each of which must be connected to source of primary
power.
•
•
•
•
Apply power to all frames in the system.
Wait a few seconds for each frame to perform processor boot-up, and observe status of the
RUN/ERROR LED located on front edge of each logic card as shown by Figure 5-16.
This LED will initially light red upon application of power, but should change to green after the
on-board processor has completed start-up.
Verify that the LED is green on all EDXE frames.
Figure 5-16 Run/Error LED Location
•
Once the initial power-up procedure is completed on all frames, replace front panels on each
frame by aligning front panel and tightening two thumbscrews, Figure 5-17.

Chapter 6 Introduction to DRS Operation
6.1
ROUTER SYSTEM CONTROL SOFTWARE
Control and set-up operations for the EDRS router system are done through the graphical user interface
(GUI) screens of PESA’s Cattrax software control application communicating with the individual frame
controller(s) located in each DXE frame, and the system controller hardware located external to the
DRS router.
In order to prepare a DRS system for operation, there are two distinct configuration procedures that
must be performed – hardware configuration and router configuration. Both types of configuration
procedures are accomplished by entering or editing configuration data through screens of Cattrax and
downloading data to the controllers.
When you select a status or control screen for any channel group, hardware configuration is read from
the active frame controller module for the channel group EDXE and the pertinent configuration data is
displayed by the screen or menu. Through Cattrax, you may view or modify existing configuration
settings or data. As configuration data is entered or modified on the GUI screen, it is stored by the
control application on the host PC – and only on the host PC. Changes entered do not get written to the
frame controller, or become active, until the operator issues a command from the control application to
download the hardware configuration data.
6.2
HARDWARE AND ROUTER CONFIGURATION FILES
Hardware configuration is where the PERC1500 (P1K) Frame Controller in each EDXE frame is
configured for the number and type of audio blocks under its control and a numerical input/output
channel range is assigned to each block. Although hardware configuration functions are performed
through Cattrax, the system controller hardware has no real intervention in this procedure.
Also as part of DRS configuration it is possible to set several audio characteristics for individual input
and output channels, such as gain, balance, phase inversion and stereo remedies. This configuration data
is not saved as a part of the router configuration file, however, it may be saved as a separate file onto
storage media for future modification or use. Refer to DRS Technical Manual for further information.
In order for the system controller to operate, a Router configuration file must be written and loaded into
controller memory. This file contains programming data for individual sources and destinations such as
where (frame and physical connector) each signal connects to the system, the type of signal and names
you wish to associate with each; as well as switching levels, components, source groups, destination
groups, and other system functions.
Router configuration procedures are typically performed when configuring an entire router system as a
function of installing the system controller. Procedural steps for creating or editing a router
configuration file are included with system controller documentation. If the router configuration file is
not already programmed into the system controller, or if you need to modify the configuration to include
audio signal assignments, please refer to the User Guide for your specific system controller device.
It is through router configuration that audio signals available through DRS can be paired with video
signals in a video matrix frame for AFV or breakaway switching as a group. In many installations,
remote control panels are located at operator stations or consoles; these are programmed through the
router configuration file and allow an operator to control designated functions of the router from a
remote station.
6-1
ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
A router configuration file may be named and saved allowing it to be retrieved to the host PC for future
modification or use. Multiple router configuration files may be written, stored and loaded to the system
controller as needed to allow quick access of different operational set-ups for the routing system.
Remember, however, that the act of generating, editing or saving a router configuration file does not
download the configuration data to the system controller.
With respect to the EDRS router, all control system components (system controller, host PC running
Cattrax, and up to 20 PERC1500 frame controllers) communicate over a standard 10/100 Ethernet link.
Any EDRS system must have a system controller interfacing with the PERC1500 frame controller(s)
located in each DXE frame to control operation of the router. Hardware and router configuration,
operation and monitoring functions of the DRS are all accomplished using tools available through the
Cattrax software control application. If the control system components are not set-up for either standalone network or LAN Ethernet communication, establish this connection before continuing. In order to
upload or download a router configuration file, modify operational parameters or perform
monitoring/diagnostic functions to the DRS system, the host PC and Cattrax must have an established
link with the system controller.
6.3
SETTING FRAME CONTROLLER IP ADDRESS AND DXE FRAME CONFIGURATION
Each EDXE frame in a DRS system must be configured for the control system to communicate with its
frame controller(s) and properly access its input and output channel assignments. This is done by setting
the rotary Frame I/D Selector switch located on the frame rear panel. Figure 6-1 illustrates the location
of the rotary switch.
In previous text we introduced the rotary switch present on each EDXE frame, and stated that the setting
position of this switch assigned the IP address offset from the base address to both the primary and
secondary controller slots in an individual frame; and also, based on the setting and address offset
assigned, determined whether the controller(s) is functioning in the primary or redundant EDXE frame
for the channel group.
Figure 6-1 Rotary Switch Location – EDXE Rear Panel
Three operational parameters for an individual EDXE frame are determined by the setting of this
switch:
EDXE I/O Range -
Assigns the input and output channel group processed by the EDXE.
Primary/Redundant EDXE - Assigns Primary or Redundant status to the EDXE.
IP Address -
Determines the IP Address increment of the PERC1500 Frame Controller
Module(s) installed in each EDXE. Notice from Table 6-1 the IP address
determined by each switch position to the various frame controller(s) is the
Base IP Address incremented sequentially in the fourth octet of the
address.
6-2
ENTERPRISE DRS AUDIO ROUTING SYSTEM
Publication 81-9059-0699-0, Rev. B
March 2014
Each PERC1500 module is factory configured to a Base IP Address of 192.168.1.201 and a Subnet
Mask of 255.255.0.0. The operating IP Address assumed by an individual frame controller module is
determined by the Base IP Address, the position of the rotary switch in the DXE frame and the module
slot within the DXE frame the module occupies.
Table 6-1 identifies switch settings and the associated parameters.

•
If you are configuring a 1536 x 1536, non-redundant system, the switch setting on the single
EDXE required for the configuration is One (1). This setting identifies the EDXE as Primary
with I/O channels 1-1536. A single Power Supply/Frame Controller Module is installed in Slot
1 (Primary Controller). Assuming a base IP Address of 192.168.1.201, the operating IP Address
for the frame controller is 192.168.1.201.
•
If a redundant Frame Controller is added to slot 2 (Secondary Controller) of this frame, the
operating IP Address assumed by this controller is 192.168.1.202.
•
As a final example, if a second EDXE frame is added to this configuration for system
redundancy, the rotary switch setting for this second frame is Six (6) – Redundant EDXE for
I/O Channels 1 – 1536. The primary controller assumes the operating IP Address of
192.168.1.211, and if a second controller (redundant slot) is added to this frame it assumes the
operating IP Address of 192.168.1.212.
The Frame I/D Select switches are set at the factory to order specifications, and should not require
resetting. If, however, a switch setting is accidentally changed, or if you should wish to reconfigure the
system, follow these examples and Table 6-1 to determine the proper switch setting for EDXE frames in
the system.
Before applying power to the system for the first time, PESA recommends that you verify the setting of
the rotary switch on every EDXE frame used in the configuration.

6.4
CHANGING THE DEFAULT IP ADDRESS OF A FRAME CONTROLLER MODULE
Remember the base IP address is the address programmed into flash memory of all PERC1500 frame
controllers in the EDRS system, and it becomes the nomenclature used to identify the entire EDRS
system on the network. On power-up of the EDXE frames in the system, each frame controller
determines and assumes a unique operating IP address as discussed in Paragraph 4.1.5.
In some applications it may be necessary to set the base IP address of the EDRS system to a value other
than the factory assigned address to accommodate your particular installation; this is easily
accomplished through the control application. Changing the IP address may be required for a number of
reasons; for example, in new EDRS installations the IP addresses of the frame controllers occasionally
need to be set differently from the factory ship configuration to avoid addressing conflicts with other
network hardware.
Assume you are installing a new EDRS system and wish to use the IP addresses 192.168.5.101 through
192.168.5.120 for the P1500 frame controllers, rather than the default values set by the factory. Using
the control application you would change the base address loaded into all frame controllers to
192.168.5.101. When the “new” address is saved to the controllers, it is simultaneously written to all
frame controllers in the system. Saving the new address will cause the frame controllers to re-boot and
thereby assume their “new” unique operating addresses derived from the changed base address.
The base IP address of the P1500 frame controllers may be set to a value that best suits your network,
with a few caveats:
•
You may set the first three octets of the IP address to any values needed for your installation.
•
You may assign any valid value (1 thru 254) to the fourth octet, keeping in mind that the
number you assign will be incremented when assigning IP addresses to each of the frame
controllers in the system. The numbers 0 (zero) and 255 are not valid for use in the fourth octet.
•
When determining the number for the fourth octet PESA recommends that you dedicate a block
of 20 sequential numbers even if your system has less than 20 frame controllers to allow for
future expansion.
Complete procedures for changing the system base IP address using Cattrax are the same as for a
traditional DRS router. Refer to DRS Technical Manual for further information.

DUAL (REDUNDANT) P1500 FRAME CONTROLLERS
When an EDXE frame is equipped with dual frame controllers, one is always functioning as the active
controller and the other is the standby controller. Installation position in the frame is not an indicator of
which is the active controller. During operation, the standby controller monitors the health of the active
controller and will automatically become active and take over control of the EDXE frame if it detects a
problem. A standby controller can become active for any of the following reasons:
•
User presses the “Active” button on the front edge of the circuit board in the frame.
•
User requests the standby P1500 become active by a command from Cattrax.
•
Standby P1500 loses serial communication with the active P1500.
•
Active P1500 cannot make an Ethernet connection.
•
Active P1500 experiences communication failure with the EDXE.
•
Active P1500 controller is removed from its frame slot.

Chapter 7 EDRS Operation Using Cattrax
7.1
INTRODUCTION
Most functions and procedures of Cattrax used with the Enterprise DRS router are the same as for the
traditional DRS router as presented and discussed in Chapter 8 of the DRS Technical Manual.
This chapter presents and discusses the following operations that are unique to the Enterprise DRS:
•
EDRS Devices View Entries
•
EDXE Summary Screen Display
•
Channel Group Status and Set-Up Screens
•
Status Display Screen
•
Channel Group Port Configuration Screen
•
I/O Port Summary Screen Display
For an introduction to Cattrax, basic operation of the software application and operational procedures
for all DRS-specific Cattrax menus and operator screens not included in the following paragraphs, refer
to the DRS Technical Manual, Chapter 8.
7.2
EDRS DEVICES VIEW ENTRIES
When an EDRS router is discovered on the network, its assigned name is added under the Routers
parent header, shown by Figure 7-1 using the system name EDXE System as an example menu entry.
Expanding the menu entry reveals a listing of all channel groups and components in the system.
Clicking any entry in the listing opens a menu of control and status screens available for the component
in the Menu Tree window, and also displays operational properties for the selected assembly in the
Device Properties Window area.

EDXE SUMMARY SCREEN DISPLAY
With the top-level EDRS entry selected, the EDXE Summary window is displayed in the Main Window
area, as shown by Figure 7-2. This screen is a display-only window that identifies the operational
characteristics of each DXE in the EDRS system.
Figure 7-2 EDXE Summary Screen
7.4
CHANNEL GROUP STATUS AND SET-UP SCREENS
Locate and expand the Routers entry in the Devices View window, as shown in Figure 7-3, expand the
DRS router entry to reveal a listing of all channel groups in the system. Each entry in the listing
identifies a channel group by its DXE group identifier and the numerical output channel range of the
specified group.
Expanding the menu entry for any of the channel groups reveals entries for components that configure
that specific group. Selecting any of these entries opens a menu of status and control menus available
for the component under the Menu Tree window. Within the menu structure you will find entries under
the heading I/O Ports that correspond to control menus for each of the signal frames attached to the
EDXE I/O ports. At the same level as I/O Ports, there are entries for the EDXE frame(s), primary and
redundant, if present. Each EDXE frame is further identified by the IP address of the PERC1500 frame
controller that is currently active for the frame. Expanding the entry for either EDXE reveals an entry
for the PERC1500 Frame Controller. Clicking this entry opens a status and control menu listing in the
Menu Tree window for functions pertinent to the frame controller(s) within the indicated EDXE, and
also reveals entries that identify the active/standby status for each frame controller in the frame.
Selecting any EDXE channel group top level entry in the Devices View window displays the status and
set-up screen menu for the group in the Menu Tree window as shown in Figure 7-3. For this example
screen, channel group I/O Range 1 – 1536 supported by DXE1 is selected.

Figure 7-4 Status Display Screen
Looking at Figure 7-4, for each DXE frame in the channel group, the display provides real-time status
of frame power supply voltages, and the surface temperature and temperature status of the circuit board.
The Link box provides status display for the fiber optic links between channel group EDXE frames in
DRS systems expanded beyond 1536 x 1536. This box identifies, for each active link, the receive (Rx
Power) and transmit (Tx Power) power of the fiber optic laser module, the module temperature and the
current operating wavelength of the laser.
The next two boxes indicate status of certain communication connections between the signal frames and
the DXE. This information is not pertinent to daily DRS operation and is provided for use by
technicians when servicing the DRS system.

CHANNEL GROUP PORT CONFIGURATION SCREEN
As was discussed in Chapter 4, a channel group consists of at least one EDXE frame and its associated
audio frames, and is identified by the numerical range of I/O signals it can process. Audio frames and
blocks are connected to EDXE frames through the I/O Frame Port connectors on the DXE rear panel in
a numerical sequence, and the order of connection assigns the numerical range of input or output
channels handled by each block. Every I/O port must be configured through the Port Configuration
menu screen to identify the type of audio block(s) connected to the port and assign the numerical bank
of channels to the block. Figure 7-5 shows a typical port configuration menu screen.
Figure 7-5 Example Port Configuration Screen
The main display portion of this window contains a table with a row entry for each of the 24 frame ports
on the EDXE. Each row is composed of columns that identify certain operational and configuration
parameters about the frame port. Before continuing to the procedure for entering hardware configuration
data, we need to closely look at each of the columns. Refer to the example DXE Frame Port
Configuration Screen shown by Figure 7-5. You might also find it helpful to have a “live” port
configuration screen open on the host PC for reference.
When the Port Configuration entry is selected from the Menu Tree listing, data for the channel group is
refreshed as follows prior to display:
•
Each EDXE, primary and redundant, if present, polls its frame I/O ports to determine the type of
audio block(s) currently attached to each port.
•
The hardware configuration data loaded into the primary frame controller in the primary EDXE
frame is read to determine the type of audio block(s) programmed in the configuration file as
being attached to each I/O port.

At the top of the main window screen the channel group shown for configuration is identified as the
DXE, with the base IP address and its I/O range nomenclature displayed. The table in the main display
area contains 7 columns, and displays configuration data for the primary EDXE and, if equipped, the
redundant EDXE for the channel group. A brief explanation of the data displayed in each column
follows:
•
PORT - The left-most column labeled PORT, is a listing by port number of the 24 physical
EDXE input/output ports.
•
I/O Board Type – This entry displays for each of the I/O ports the type of signal frame that is
currently defined by the configuration file read from the primary frame controller in the
primary DXE for the indicated port. This column allows the user to modify the hardware
definition for any port using the pull-down menu in the cell.
•
Inputs Start/End – Indicates the numeric range of input channels assigned to the port. This
entry is determined by the frame type specified in the previous column and is automatically
assigned by the GUI application.
•
Outputs Start/End – Same as the previous column, except it displays the numerical range of
output channels assigned to the port.
•
Reserved – A check in the box indicates that the range of input/output channel numbers and
frame type have been reserved for future implementation.
•
Detected Board Type, Primary DXE – When the port configuration screen is selected the
Primary DXE frame for the channel group polls the audio block(s) attached to each of its I/O
ports. This column displays the results – and indicates the frame type of the actual hardware
connected to the indicated port. A comparison is then made between the actual detected
hardware and the frame type indicated in the I/O Board Type column. If the actual and
indicated frame types are the same, the cell is displayed with a green background. Should the
hardware configuration file indicate a different frame type from what is actually detected, the
cell is displayed with a red background.
•
Detected Board Type, Redundant DXE – When the port configuration screen is selected the
Redundant DXE frame, if present, for the channel group polls the audio block(s) attached to
each of its I/O ports. This column displays the results – and indicates the frame type of the
actual hardware connected to the indicated port. A comparison is then made between the actual
detected hardware and the frame type indicated in the I/O Board Type column. If the actual
and indicated frame types are the same, the cell is displayed with a green background. Should
the configuration file indicate a different frame type from what is actually detected, the cell is
displayed with a red background. If a redundant DXE is not used in the installation, the column
is grayed-out.
The Port Configuration screen also includes a graphic image of the EDXE rear panel with the I/O port
connectors color coded for a quick visual reference to port status.

•
•
•
7.7
When the screen is open from the GUI, the frame type for each frame attached to each I/O port
of the indicated DXE is detected.
For each I/O port, a comparison is made between the actual frame type connected and the frame
type programmed into the configuration file read from the primary frame controller in the
primary DXE for the channel group.
A comparison is made between the actual frame type connected to each port and the frame type
indicated by the configuration file.
Any comparisons not resulting in a positive match are indicated by a red background in the
display cell.
PORT CONFIGURATION PROCEDURE
Port Configuration for the Enterprise DXE frame is an identical process to configuration for the
traditional DRS router, with the exception that there are 24 ports to configure instead of 8. Refer to
Chapter 8 of the DRS Technical Manual for procedural steps.
7.8
I/O PORT SUMMARY SCREEN DISPLAY
With the top-level I/O Ports entry selected, the I/O Ports Summary window is displayed in the Main
Window area, as shown by Figure 7-6. This screen is a display-only window that provides real-time
readout of the operational characteristics for each signal frame attached to the DXE.
