Chapter 4 - Introduction to CAB 4n
Using a CAB 4n with a NION
The CAB 4n is designed to work in conjunction with a NION.
In the example below, a project is created in NWare, then deployed to a NION, so it can
control the CAB 4ns on the network.
Note: There is no fixed limit on the number of CABs that a NION can control, but adding
more CABs will consume more system resources on the NION.

2. FAULT LED Illumination of the Fault LED indicates an unexpected condition within
the CobraNet interface. Some fault conditions will also light the RX Error and/or TX
Error LEDs; this is to give more specific indication if the unexpected condition is in the
receive or transmit processes. The errors are reported by a series of flashes.
3. CONDUCT LED Indicates the CAB 4n is an active Conductor on the CobraNet
network. Only one Conductor is allowed per network.
4. LINK LED Indicates the physical layer connection has been established between the
CAB 4n and the network switch. This function is duplicated in the software control panel
(available via the
block in NWare).
5. RX LED Indicates the presence of data being received into the CAB 4n from the
CobraNet network.
6. TX LED Indicates the presence of data being transmitted from the CAB 4n onto the
CobraNet network.
7. HARDWARE BASE ADDRESS INDICATORS or AUDIO METERS. These LEDs
have a dual purpose.
a) Before a valid CobraNet control connection has taken place, these indicate the
hardware base address (ID). They are used in conjunction with the hardware base
address switches (see item #1 above) to set the Hardware ID, which allows NWare
and the NIONs to communicate with, and control, the CAB 4n.
b) Once the CAB 4n is being controlled by the NION software, these become peak
reading LED ladder displays, indicating audio input/output levels in the analog
domain. Signal level is displayed after the adjustable gain stage and before the A/D
converters.
8. POWER LED Indicates that the CAB 4n is powered from an AC mains power source.

Introduction
The CAB 4n is designed to mount in a standard EIA electronic equipment rack. Because the
CAB 4n includes forced air cooling, rack mounted vent panels are not required for most
installations. However, vent panels may be required in large installations where multiple
units are mounted in a single rack. It is generally accepted that a ratio of 2:1 usually provides
adequate performance. In installations where adverse conditions exist, and room
temperatures are likely to rise, additional vents should be installed.
This product should be installed so that its mounting position does not interfere
with proper ventilation. Do not block air intake or exhaust vents.
When dressing off wiring harnesses, take care with CAT 5 cables. Do not tie-wrap
bundles of CAT 5 wire too tight. Leave plenty of room for bends, allowing the
cable to progress naturally from the RJ-45 connector. Creating tightly wrapped
CAT 5 wire bundles can cause data transmission errors.
What you will need
ƒ

A MediaMatrix NION with CobraNet.
The latest NWare software. (Updates can be downloaded from the MediaMatrix
website.)
A computer running Microsoft Windows, with monitor, mouse and keyboard.
At least 1 CAB 4n with associated MM™ I/O 4 ch cards loaded.
A network switch connected to the CobraNet network.
Note: The selection of a proper network switch is critical for a successful
implementation. Although CobraNet is an Ethernet protocol, there are performance
issues that must be considered when selecting this switch for use in CobraNet audio
systems.

An assortment of CAT 5 cables.
An audio source, power amplifier and loudspeaker.
A small Phillips screwdriver and a T-15 Trox screwdriver.
In MediaMatrix, the minimum CobraNet network consists of a single NION, a CAB 4n
audio bridge loaded with appropriate MM™ I/O 4 ch cards and a single Ethernet switch.
Many systems will include more NIONs and CAB devices, but this is the most basic
configuration.

Connections
CobraNet network connections
The CAB 4n features a number of different types of connectors. The first priority is the
CobraNet™ network port. This RJ-45 connector is designed to connect with standard, offthe-shelf Category 5 (CAT 5) cable for use with standard Ethernet network switches.
Note: The network must be properly designed for each system. If networking is not a normal
part of your experience, we suggest that you partner with someone with networking
experience.
Configuration 1
A typical CobraNet system includes a CAT 5 cable from each CAB to a network switch. An
additional CAT 5 cable connects the switch to one or more MM-DSP-cn cards within the
MediaMatrix frame or NION CM-1 card.
Note: The example below is the most basic configuration. Large systems on managed
networks can get very complex. We recommend that you get this configuration working
before attempting a more complex one.

Configuration 2
Instead of using a switch, you can connect the CAB CobraNet port directly to the CobraNet
port on your NION. However, this type of direct connection requires a crossover cable. For
more information, we recommend that you search the internet.
Note: With this direct connection method, you cannot connect more than one CAB product
to NION CobraNet card. This type of connection is normally used for testing and
troubleshooting and has limited advantages in actual system installations.
Audio connections
Each audio connection on the CAB and NION products is a single, three-wire, balanced
analog circuit. The connections are identical for both microphone, line input and line output
connections. We recommend that audio connections are made with high quality shielded
wire.
Note: As with any electronic connection, care should be taken to ensure that the termination
is solid. There should be no stray wire strands, kinks or nicks in the wire jacket for a proper
termination.

CAB 4n Hardware Manual
RS-485 connections
All CAB series products include a powerful feature that enables you to bridge serial data
between CAB locations on the CobraNet network. You can think of this as a kind of subnetwork that travels across the CobraNet infrastructure independently of the audio data. This
feature has many uses, but is primarily for transporting control data. The CAB 4n supports
half-duplex, two-wire, balanced data transfer.
Note: Ensure that your termination is correctly installed and high quality shielded wire is
used.
The RS-485 connector has two sets of terminations that are wired in parallel. This allows
you to bus adjacent serial data connections at each network location. With this type of
connection, there is no input or output.
CAT 5 connections
Category 5 cable, or CAT 5 as it is commonly known, is a wiring standard that consists of 8
conductors, identified into 4 pairs, and although only two of these pairs are used, all four are
terminated.
It is a UTP (Unshielded Twisted Pair) configuration. The cable is coupled to in-line RJ-45
connectors, also a Bell/AT&T standard. Special crimping tools are required to make the
termination; these are widely available, as are the connectors.
Note: A single CAT 5 cable run must not exceed 100 meters.
Just like telco wire, there are stranded and solid varieties of CAT 5 cable. This is important
to know, because the RJ-45 connector is different for each type of wire. The standard bent
tine connector is intended for use with solid core wire, and the aligned tine connector is for
use with standard wire. The bent tine connector will generally work on stranded wire, but not
the other way around.
Note: Make sure your connector matches your cable type. If you are not sure, use the bent
tine variety.
Note: When terminating CAT 5 cable, it is important that the natural twist of each pair is
carried through as close as possible to the point of termination at the connector.

Chapter 5 - Installing the CAB 4n
The EIA standard requires no more than 1/2 inch be left untwisted. More than 1/2 inch of
untwisted cable will affect performance at high bit rates. Although only 2 of the 4 twisted
pairs are used for Ethernet, it is important that all pairs be terminated, and that the
conductors be twisted together in pairs. The illustrations should give you the basics for
getting your cables, and your audio system up and running. Although pre-made, molded
style cables are preferred, they are usually impractical, since your cabling route, distance and
locations are based on the jobsite conditions and not your test bench. Additionally, you will
need rack wiring, and bulk cable is the preferred way to dress off a wire harness.
Note: We recommend that you familiarize yourself with the wiring color schemes so they
are second nature to you. An error in the cabling of an audio network is often the primary
cause of system errors
Although the wiring standard used in CAT 5 cabling originates with AT&T, it is functionally
different for configuring Ethernet cabling. The Bell System uses a series of colors to identify
wire pairs. This color scheme identifies the pair numbers, and conductor polarity, and applies
to the wire, not the connector. It is important to know what pairs are which, and the function
of the pins on the RJ-45 connector. The colors are BLUE, ORANGE, GREEN and BROWN
for the first four pairs.
What is often confusing is that the pair numbers do not line up with the pin numbers on the
RJ-45 connector. In other words, conductor one of the cable (White w/Blue Strip) is not
terminated to pin one of the connector. The AT&T connecting standard always uses the
middle pins for the first pair. After that, they are staggered around, primarily to prevent
crosstalk between adjacent pairs. For Ethernet, only the ORANGE and GREEN pairs are
actually used.
Note: It is very important that you build the cable with all pairs properly terminated. This
will prevent any confusion later, and give your cable a solid mechanical connection.
For Ethernet, the BLUE and BROWN pairs are not used. The ORANGE pair is transmit
(TX), and the GREEN pair is receive (RX). There is a positive and negative conductor for
each pair, indicated by the color code. Notice on the chart that the order of the wire pairs
does not follow the connector pins. The first wire of a given pair is always the white wire
with a colored stripe and is the positive conductor. The corresponding colored wire with the
white stripe is the negative conductor for that pair.

Crossover cables
Normal CAT 5 cables are designed to connect the CAB to a network switch only. You
cannot use this type of cable to connect a CAB directly to a MediaMatrix MM-DSP-cn DPU
card or NION CM-1 card. For that you need a crossover cable.
Note: The pin assignments for a crossover cable, shown in parentheses on the chart, apply to
one end of the cable only.

Chapter 5 - Installing the CAB 4n
Crossover cables are used to connect switches to other switches or CABs directly to the DPU
card. Also, a crossover cable is what you would use if you were to connect a CAB to another
CAB, for use as a digital snake. A crossover cable is terminated the same way as a normal
cable, except that the TX and RX pins are swapped at one end to allow the transmit pair of
one device to connect to the receive pair of the other.
Normally, this crossover action is done within the switch, which is why you use a straightthrough cable most of the time. It is very easy to tell the difference between a crossover
cable and a straight-through cable by looking at the conductors in the RJ-45 connectors. If
the wiring is identical at both ends, you are looking at a straight-through cable. If it is
different, you most likely have a crossover cable, or possibly, an incorrectly terminated
cable. Look carefully at the color of the conductors. It is important to note that some
switches include uplink ports. These ports are intended to serve as a connection to another
switch. As such, the uplink port is wired to use a straight-through cable instead of requiring a
crossover cable. On some switches, uplink ports share their connection with an adjacent port,
so be sure to read the manufacturer's instructions for proper use.
Link connections
CAB 4n, 8i, 8o and 16 series products feature built-in Buddy Link functionality for creating
backup I/O configurations in mission critical systems.
Each CAB 4n Series product features rear panel, dual BNC connectors labeled LINK IN and
LINK OUT. These connectors enable you to connect adjacent CAB units for redundancy and
define the role of dual units.
28
Version 1.6.0.0
March 15, 2010
CAB 4n Hardware Manual
In this configuration, one CAB 4n is declared the primary and transmits data via its LINK
OUT connector. The other CAB 4n is the secondary, or backup, and receives data at its
LINK IN connector. A high quality, broadcast grade video cable, RG-59 with male BNC
connectors on each end, is used to make the connection between the primary and secondary
CABs. A single cable is used for dual CABs in this redundant configuration. The connection
is always LINK OUT (Primary) to LINK IN (Slave). Audio input or output signals appear at
both units, in parallel, so if one fails, the redundant unit will have the same connection.
By nature of the Buddy Link functionality, the secondary unit is always off-line until needed
and therefore the paralleling of the audio connections is of no consequence.
Note: Both units must be configured to use the same audio bundle numbers. For more
information, see Setting the audio bundle numbers.
As long as the primary unit is powered on, and it sees a good CobraNet connection (Ethernet
link status good), and it has not experienced a fault, it generates a signal from its LINK OUT
connector which inhibits the secondary unit from taking over until there is a failure or fault.
The action of the switch-over is different for each type of CAB. In the case of the CAB 4n,
input audio is present simultaneously at both units and both units will pass audio internally.
You can see this by the duplication of audio presence on the front panel meters. However,
relays on the output cards prevent audio passing out of the secondary (slave) CAB.
For input audio, the secondary CAB 4n is prevented from transmitting onto the CobraNet
network by the action of the Buddy Link. The fact that audio is present, but is muted by
relays for output, and by the CobraNet transmission being turned off by the Buddy Link,
means the quick response of the redundant CAB is greatly enhanced.
The Buddy Link feature also monitors the integrity of the link cable. When using dual CABs,
a cable failure will cause the secondary unit to take over transmission onto the CobraNet
network. The Buddy Link functionality can also be placed under software control and is used
in systems where remote access to the link is required.
Note: Using the link connectors for redundancy is limited to dual CAB units. Where
additional CABs are used, additional redundant units must also be added.
As a point of explanation, these are the CAB blocks that are configured in NWare. The
Hardware ID that allows software to control the hardware is set here.

Setting the Hardware Base Address ID
Once there is a physical connection to the network, you must assign a Hardware ID (also
referred to as a base address) to the CAB. This is done by selecting numbers using dials on
the front of the unit. This is an important step in the installation procedure as the ID will be
used to identify the unit on the network and allow audio to be passed through it.
The Hardware ID is also specified in the NWare software to allow communications between
).
the CAB and its control panel (the yellow CAB 4n icon
To set the Hardware Base Address ID on the CAB 4n
1. Remove the screws from the CAB face plate to gain access to the hardware base address
switches.
Tip: If you look carefully, there is a small arrow on each switch indicating the selected
number.
2. Using a small Phillips screwdriver, carefully set each rotary switch to the desired
number. You will feel a click as you move between digits.
A Hardware Base Address has 4 digits. Acceptable values are in hex and range from
0001 to 7FFF. From left to right, the four rotary switches represent your 4 digit
Hardware Base Address number.
Caution: Be careful not to damage a switch by using excessive force.
Note: Each CAB on the network must have a unique Hardware Base Address.
What to do next
The CAB 4n is managed and configured using NWare. Refer to the section Adding a CAB 4n
to your design in the NWare User Guide to see how to use a CAB 4n in your audio system
design.

GPIO overview
NION and CAB products include a versatile GPIO (General Purpose Input Output) system at
the rear for terminating external logic, controls, relays and other external systems. Each
control pin is supported by NWare for configuration, control and monitoring. Any
combination of control pins may be used simultaneously, regardless of the configuration.
Caution: The pin assignments for the GPIO ports on the NION and CAB devices are not the
same. Please be sure to check the documentation carefully when connecting devices to the
ports.
Configurable general purpose ports (8 control pins)
These ports represent the bulk of the GPIO functionality. Each of these ports can be
configured as follows:
Digital Output
3.0V TTL logic - Low: 0VDC - 0.4VDC;
High: 2.4VDC - 3.3VDC
Digital Input
3.0V TTL logic - Low: 0VDC - 0.8VDC;
High: 2.0VDC - 24VDC
Analog Input
Using external, regulated 24VDC supply.
Rotary encoder
Requires 2 pins and a common.
NC and NO relays (4 sets)
Four Form C relays are available for general purpose usage. These are user configurable
from within NWare.
Fault relay
A single system relay is configured for supervising project faults. This Form C relay
provides 1A contacts and is activated when the front panel fault LED is illuminated, which
indicates a muted condition.
The behavior of the fault relay is summarized below.

Connection
A 25-pin DSub connector (DB-25) is used for accessing the GPIO functions. Although you
can terminate GPIO functions directly to the DB-25 connector, we recommend that you use
the optional breakout accessory (GPIO-25: Peavey Part# 00510490).
The GPIO-25 is a convenient way to access each pin and facilitates easy rack wiring and
troubleshooting. The GPIO-25 is a DIN rail package and includes removable Euro
connectors for terminating the pins. A single DB-25 male/female cable connects the GPIO25 to the NION or CAB 4n.
