Introduction
The RAVE 520uz provides the digital audio transport and
signal processing needed to distribute audio throughout an
integrated functioning system. In conjunction with QSControl.net software, the RAVE 520uz enables the user to
design, test and deploy professional audio reinforcement
and distribution systems ranging in size from one to hundreds of channels.
A standard Windows computer is the principle user-interface for controlling the overall RAVE/QSControl system.
However, the RAVE 520uz also offers a front panel interface
for accessing critical functions.
A single QSControl.net server computer can support several
clients running QSC's latest Venue Manager software. Thus,
the sound system can be operated via several computers,
roaming wireless laptops, tablets, etc., all at the same time,
from anywhere a connection to the QSControl.net network
is available.

2- Diagnostic indicator
3- Network status indicators
4- Signal presence/clip indicators
5- Multi-function push buttons
6- Display
7- Rotary select/accept knob
8- Safe Mode switch (recessed)
The QSControl.net network can also be managed from a single computer running both the client and the server. Once all
RAVE devices in a system are configured, a computer is no
longer required on that system’s network. All basic functions of the RAVE 520uz continue to operate with or without
a control computer connected to the network.
The configurable DSP engine provides all of the functions
necessary to handle the input portion of a signal chain, such
as delays, equalization, compression/limiting, etc. Audio
output is exclusively via CobraNet .
Audio enters a RAVE 520uz either through analog universal
inputs (mic to line level with software-selectable +48V
phantom power) or from CobraNet source devices such as
QSC's line of RAVE digital audio routers. Any combination of
16 CobraNet channels (selected from up to 4 bundles of 32
channels) can be routed into the 24 x 24 DSP engine. Any or
all of the 24 DSP channels can also be routed to up to 32
CobraNet channels on the network.

Introduction (continued)
Unlike other configurable DSP boxes, the intrinsic processing latency of the RAVE 520uz is both short and fixed at
0.396 milliseconds. The delay does not change regardless of
the DSP configuration, unless the configuration intentionally adds more delay.
The RAVE 520uz also supports the new optional low-latency
CobraNet feature that provides transport at only 2.66 milliseconds delay.
Both software and firmware can be easily updated over the
network. In the future, QSC will be adding new capabilities
to both RAVE and QSControl.net. Our latest code releases

trol.net are available at www.qscontrol.net. We invite you
to visit us there.
We've applied our many years of experience in supporting
high-end installed sound with our previous system-building
products such as RAVE, QSControl, CM16a, DSP-3, DSP-4,
and DSP-30. The RAVE 520uz brings all that technology
together in one compact, powerful, easy to use system. We
are confident that your new RAVE 520uz will provide years
of dependable service and we hope it will help you, the system designer and implementer, to express your creative
audio system ideas.
Introduction - Networking the RAVE 520uz
The RAVE 520uz has two RJ-45 network connection ports on the rear panel. One port is labeled "QSControl" and supports standard
10BASE-T Ethernet. The other port is labeled "CobraNet" and supports 100BASE-TX, also known as "Fast Ethernet". In the following
sections we describe the use of these ports and show example network connection schemes.
The RAVE 520uz supports two distinct kinds of network activity; the first is audio transport via CobraNet, and the second is DSP setup
via QSControl.net. The user can choose to install one network for CobraNet traffic and a second separate network for QSControl.net
traffic. We call this the "Two Wire Interface". Alternately, it is possible to run both DSP setup data and audio traffic over CobraNet via
the CobraNet port. In this case the QSControl port is unused. We call this the "Single Wire Interface".
Under the most demanding real-time control conditions and when using the lowest latency CobraNet settings, users may experience
better QSControl.net performance using separate networks, especially when displaying a great many real-time meters. For most applications, separate networks won't provide any discernible benefits and will cost more. We therefore recommend using the Single Wire
Interface when running CobraNet.
Why CobraNet Needs Special Treatment:
Ordinary Ethernet traffic has no guaranteed time of delivery. Packets of information may arrive at their destination out of order and
some may be delayed more than others. This is fine for E-mail and even for downloading MP3 files over the Internet. Everything ends up
properly reassembled at the destination, but how long this takes will vary according to network loading, span, etc. In contrast, CobraNet is "real time" - it delivers audio with a minimal, consistent transmission delay. CobraNet is designed to use as much of conventional
networking technology as possible while providing both guaranteed time of delivery and isochronicity - maintaining a phase-locked
sample-accurate clock across the entire network. These requirements mean that ordinary unregulated Ethernet data cannot be freely
mixed with CobraNet information. The two can coexist on the same wire, but only by adhering to the proper rules.
To learn more about CobraNet and appropriate network topologies, please visit http://www.qscaudio.com/products/network/
resources.htm and http://www.peakaudio.com/CobraNet/background.html.
Notes on Network Systems Design:
As with any communications system, the reliability and performance of a local area network is intimately related to the designer's skill
and knowledge in implementing a topology that is robust, efficient and standards-compliant. Proper network design is even more critical in distributed multimedia systems. Therefore, it is important for the system designer to realize that some conventional network
practices must be avoided. Although each network design is unique and may carry its own performance requirements, compliance to
the following three points will assist in building an audio network that is trouble free and efficient.
First, audio and conventional data communications deliveries should not exist on the same LAN or VLAN. The exception to this is the
RAVE 520uz Single Wire Interface, which offers a solution for converging audio and QSControl.net onto the same LAN or VLAN. However, conventional communications, such as corporate networks, print services, e-mail and Internet access, should not exist alongside
CobraNet audio and QSControl.net on the same LAN or VLAN. Further, CobraNet audio and QSControl.net data should not exist
together on the same LAN or VLAN when implementing the Two Wire Interface. This is not to say that conventional communications
cannot share the same network hardware with a RAVE 520uz. In fact, common network hardware, such as managed Ethernet switches
and media converters, can service both RAVE 520uz products and conventional data communications equipment so long as the managed switch or media converter are partitioned into separate network domains. This is normally done by configuring a separate VLAN
for each data type. (Some switches may allow individual port assignments or support partitions through DIP switch selection.)
Second, CobraNet audio must traverse either a repeater domain or a network switch domain. The point here is that the CobraNet port
on a RAVE 520uz must connect directly to, and only to, either a repeater LAN or a switched Ethernet LAN. Hybrid networks containing
both repeaters and switches are not permitted on the audio segment. Connecting the CobraNet port to a repeater that is in turn connected to a network switch poses an illegal and non-compliant condition. We recommend always connecting the QSControl and/or
CobraNet port(s) directly to network switch ports.
5
Third, the RAVE 520uz and QSControl.net system are targeted at network switch deployments. The consumer costs of Ethernet
switches have continued to fall over the last several years and are now comparable with repeaters on a per port basis. In addition, the
sophistication and scalability of network switches make them ideal for new installations. However, we do realize that designers may
wish to add RAVE products to existing audio network installations that are built on repeater LAN topologies. This applies primarily to
existing CM16a and RAVE networks. For this very reason we continue to support connectivity to network repeater hardware with the
RAVE 520uz. Support for network repeaters exists only with the Two Wire Interface. That is to say that the QSControl port and the
CobraNet port must be connected to separate repeater LANs. Even when properly configured, audio channel capacity is severely limited and both audio and control network expansion is limited by the respective capacity of each segment. In other words, scalability
ceases to exist when bandwidth demands on the QSControl.net segment approach 10 Mbps and demand on the CobraNet segment
approaches 100 Mbps. Obviously, we recommend taking advantage of switch network technology whenever possible.
It should be noted here that while the CobraNet port on a RAVE 520uz is restricted to repeater LAN or switch LAN deployments, QSControl.net is a TCP/IP standards-compliant network system and therefore supports operation on network repeaters, switches and routers.
When implementing the Two Wire Interface, the QSControl.net segment does not require a single topology data path and therefore
repeaters, switches and routers may be assembled on the LAN in a hybrid fashion.

All of this may seem daunting if you are new to networking. However, it all boils down to connecting a few simple cables between various networking devices. Most of the time it "just works". QSC helped pioneer CobraNet with our RAVE ™ products and there are hundreds of installations all over the world, in theme parks, hotels, stadiums - everywhere. They run hum-free, sound great and are very
reliable.
The following examples will help get you started, but they just scratch the surface of what can be achieved with advanced networking…
Example #1 - QSControl.net X-over mode:
This is the simplest connection you can make between the RAVE 520uz and your computer. Use a CAT-5 crossover cable connected
between the RAVE ‘s QSControl port and your computer's Network Interface Card, (NIC). No network switch is required. With QSControl.net server and client software installed and running on your computer, you will be able to completely set up your RAVE 520uz.
6
Example #2 - CobraNet X-over mode:
This is the simplest connection you can make between a RAVE 520uz and a “destination” product such as the BASIS 922az/902zz/904zz
or the RAVE 522aa.The RAVE 520uz is the audio “source” in this example. Use a CAT-5 crossover cable connected between the CobraNet ports of each unit. No network switch is required. This connection allows audio to pass from the RAVE 520uz to the BASIS/RAVE
unit over CobraNet.
Combining example 1 and 2 lets you setup one unit at a time, much as you would have to do using a point-to-point RS232 connection,
while passing audio between them, all without a network switch. However, you would have to physically connect your computer first
to one unit and then to the other. With this elementary connection you don't have a true network. It is like making RS-232 connections - except that performance is much better.
All the other examples are of proper networks and all require a network switch. On a proper network, you have direct access to all
RAVE/BASIS units all of the time without having to physically switch between them. You still get the great performance of TCP/IP
over Ethernet. (And we believe QSC's advanced networking software provides the best performance of any networked audio control
system available today, including Ethernet based systems from competitors.)
7
Example #3 - Single Wire Interface:
Here all QSControl.net and CobraNet traffic shares the same single CAT-5 cable between the RAVE 520uz and an unmanaged Ethernet
switch. The QSControl.net system manages traffic flow efficiently and reliably so that all audio and control data is delivered to its
appropriate destination anywhere on the network. This configuration works well when CobraNet audio deliveries are point to point.
Though the example shows only one RAVE 520uz and one “audio destination” product (such as the BASIS 922az) as many devices may
be connected as there are available switch ports. All RAVE/BASIS units will be able to communicate simultaneously with the computer.
All will have CobraNet audio output capability, with the exception of source-only devices like the 520uz. Switches can be connected to
other switches to build larger networks; all of the normal networking principles apply. (Note: there must be at least two CobraNet
devices online (one source and one destination) for any data to come out of the CobraNet port.)
8
Example #4 - Two-Wire Interface (shared network hardware):
This example illustrates the Two-Wire Interface with a managed Ethernet switch. The switch is configured with multiple virtual
local area networks (VLANs). Ethernet deliveries can only reach destination ports belonging to the same VLAN from which it was
sourced. The figure shows a separate VLAN for QSControl.net traffic and a separate VLAN for CobraNet audio traffic. This configuration essentially provides a dedicated network for RAVE/BASIS management (including the system controller) and a second,
dedicated network for CobraNet audio. As with the previous example, as many RAVE or BASIS units may be connected as there
are switch ports available. All RAVE units will be able to communicate with the computer. All destination products will have
CobraNet audio, providing a CobraNet source (i.e. RAVE 520uz) is putiing audio data onto the network. Switches can be connected
to other switches to build larger networks; all of the normal networking principles apply.
9
Example #5 - Two-Wire Interface (separate network hardware):
Example #5 is conceptually similar to example #4. The difference here is that separate networks are created by providing each local
area network (LAN) with its own network switch. Therefore, traffic segmentation is physical rather than logical. Example #5 also provides an additional level of fault tolerance, although at the expense of additional network hardware. The figure shows a separate network switch for QSControl.net traffic and a separate network switch for CobraNet audio traffic. All of the previous comments regarding
network expansion still apply.

Unpacking
There are no special unpacking precautions. However, it is recommended you keep the original packing material for reuse in the rare
event that service be required. If service is required and the original packing material is not available, ensure that the unit is adequately
protected for shipment (strong box of appropriate size, sufficient packing material to prevent load-shifting or impact damage) or call
QSC’s Technical Services Department for packing material and a carton.

Mounting
The RAVE 520uz can be used in or out of an equipment rack. Rack mounting is optional. Adhesive rubber feet are included for non-rack
mount installations. Use them to prevent the unit from scratching or marring support surfaces.
Rack Mounting
Rack mount the RAVE 520uz by supporting it from underneath while aligning the mounting holes with the threaded screw holes in the
rails; install all four mounting screws and washers and tighten securely. Ensure use of all four mounting screws in order to minimize the
chance of bending or distorting the rack mount ears. If the RAVE 520uz is to be transported while in a rack, we recommend supporting
the rear of the chassis. This will help prevent the unit from being damaged from the increased mechanical stresses of portable and
mobile use. The RAVE 520uz’s chassis includes integral rear mounting tabs for securing to the rack mounting ears.
Be certain not to block
the cooling air ventilation openings on the
sides of the chassis.

General Information & Configuration Memories
Network
The network should be operable and QSControl.net software should be installed/running on the system controller computer.
CobraNet Connection Loss
If you are operating with a valid CobraNet network, and the connection to the network is disrupted, audio will momentarily mute, allowing the RAVE 520uz to synchronize with its internal clock. If CobraNet network connection is re-established, the audio will mute again
while the RAVE 520uz synchronizes with CobraNet.
Configuration Memories
The RAVE 520uz has non-volatile storage locations that contain settings for the device as well as DSP signal flow. The storage locations make it possible to set up the RAVE for different situations and quickly recall the setup with or without QSControl.net software
using the front panel controls.
13
Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC
power inlet on the back of the RAVE 520uz. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240
Volts AC, 47 to 440 Hertz, without any changes. If a different type of
IEC power cord is required than the one supplied with your 520uz,
contact QSC’s Technical Services Department.
CobraNet
Connect one end of a category-5 cable terminated with a RJ45 plug
into the CobraNet receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the RAVE
520uz and push firmly until the connector locks into place (usually
an audible “click” can be heard). Connect the other end to the
appropriate CobraNet network port.
QSControl
Connect one end of a category-5 cable terminated with an RJ45
plug into the QSControl receptacle. Insert the RJ45 plug into the
receptacle with the lock-tab oriented toward the bottom of the
RAVE 520uz and push firmly until the connector locks into place
(usually an audible “click” can be heard). Connect the other end to
the appropriate QSControl.net network port.
Analog Universal Audio Inputs
Eight balanced audio inputs are provided, CH 1 INPUT - CH 8
INPUT. They accept everything from mic level to line level signals
and are equipped with software-selectable +48V phantom power.
Plug the input signal terminal block connectors into the input receptacles. Connection pin-out is printed on the rear label for reference.
Refer to the illustrations for balanced and unbalanced connections.
Use balanced audio inputs whenever possible.
Each input has software-selectable +48V phantom power. Use caution when connecting equipment (particulary unbalanced equipment).
Omni In
The six Omni In connectors are two-pin terminal block connectors.
They accept contact closure, TTL logic signals, 0-5 VDC control voltages, or 10k ohm variable resistors. The contact closure and logic
devices accommodate on/off or state-change events; the variable
resistor input provides full 8-bit resolution allowing for incrementalchange events. Refer to the illustrations for connection recommendations. NOTE! +48 volts is the absolute maximum that can be
applied to the + pin without damage. Voltage is with respect to
chassis or the - pin.
Logic Out
The four Logic Out connectors are two-pin terminal block connectors. They provide CMOS logic level compatible signals for external
devices.

at left, for explanation.
RS-232
The RS-232 is a utility serial port for accessing diagnostic and setup
features. Connect to an available COM port on your PC and communicate using a terminal control program such as Windows Hyperterminal.
Use a normal serial data cable with a DB-9 male plug to connect to
the RAVE 520uz. To connect the cable, orient the connector properly,
then push into the receptacle until it is firmly seated; tighten the
retaining screws “finger tight”. Communications should be 9600
baud, no parity, 8 data bits, 1 stop bit, and flow control Xon/Xoff.
LED Indicators
When the RAVE 520uz is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD
display.
POWER Indicator- This blue indicator illuminates when the RAVE
520uz is plugged into a properly functioning AC source. There is no
power switch on the RAVE 520uz. This helps to prevent accidental
system shutdowns.
DIAGNOSTIC Indicator- This red diagnostic LED reports several
possible operational conditions. During boot-up, it is used to continually blink a “dot-dash” pattern if the power-on memory self-test fails.
During normal operation, if any non-recoverable system fault occurs,
the diagnostic indicator will remain on, requiring a power restart. If
this condition persists, contact QSC’s Technical Services for assistance.
The diagnostic LED is also used to indicate an update is in progress
during a remote firmware update cycle. First, the LED will blink
slowly, indicating the memory erase cycle, then it will blink rapidly,
indicating the memory write cycle. NOTE! During a firmware
update, it is critical the unit remain powered on for the entire
process in order to complete successfully.
The diagnostic LED may also be controlled by using the QSControl.net
software. This feature is particularly helpful for identifying a particular unit.
(continued, next page)
15
LED Indicators (continued)
QSControl and CobraNet Network Status (Port) Indicators- There is a group of LEDs on the front and rear panels
labeled RX, TX and LINK. One group is for the QSControl.net network port and the other for the CobraNet network port. Their
functions are described below. Note: Port indicators on rear panel are color coded to match the corresponding color-ring
around the QSControl and CobraNet RJ45s.
RX (receive)- This indicator illuminates any time the RAVE 520uz receives data from the corresponding network.
TX (transmit)- This indicator illuminates whenever the RAVE 520uz transmits data onto the corresponding network.
LINK STATUS- The corresponding indicator illuminates when the RAVE 520uz is connected to an operating network.
SIGNAL indicators- These indicators will illuminate green for input signals -40dB to -10dB below full scale; yellow for signals between -10dB to -2dB below full scale; red for -2dB to full scale (or clip).
LCD Display and Controls
The RAVE 520uz has a 2 line X 16 character LCD display. The display and the multi-function push-button switches on either
side provide data access and editing capability. The push-button switches on either side of the display are used to navigate
through the menus. The rotary select/accept knob is active for many displayed items allowing you to scroll through choices by
rotating the control, and accepting choices (entering) by pushing in on the control.
The accessible menus and sub menus may appear differently than the example shown. Software updates may occasionally
improve the interface. The basic navigation flow for the RAVE 520uz menu system is shown on the following page.
Front Panel Password Lockout
The password lockout provides the ability to restrict access to all of the editable parameters available on the LCD front panel.
This feature is enabled or disabled via QSControl.net software only (refer to the “General Tab” area and click on the “Front
Panel Password” button). When the lockout feature is enabled, all front panel LCD functions are readable, but editing of
parameters is now password protected. While in this mode, any attempt to edit a parameter will require the user to enter the
Front Panel Password. The default factory password is “qsc”. The password is stored in the RAVE unit and can be changed
using the QSControl.net software.
Once the password has been correctly entered, the RAVE will allow edits to the parameters.
After 5 minutes of inactivity, the RAVE will automatically reset the Front Panel Password lockout. Re-entry of the password
will be required to resume editing.
The lockout mode can be deliberately disabled via the “Disable Edits” check box in the Front Panel Password menu of the
QSControl.net software.
16
Use rotary data wheel to edit data. Rotate to
move cursor and push to accept change.
LCD Navigation Map
Left side buttons have screen dependent functions.
This read-only screen is the “out of the box” default
display after power up. This is the most desired
information when first setting up a network system.
Once user moves to a different screen, the last
screen accessed becomes the new power up
default.
Boot Screen
Right side buttons serve as up/down
navigation.
Arrow characters indicate right side
button context. If additional menus are
available, the arrow character will be
shown.
*Note: After successful password
entry, all screens with editable
parameters will have read write capability. Without password entry, these
screens will be read-only.

Getting Started
This section outlines one of the simpler methods of getting familiar with your RAVE and the QSControl.net software. The goal of this
procedure is to get your computer and the RAVE connected and communicating and the QSControl.net software installed and running.
After the software is installed and running, refer to the software’s Help file for all software related operation/issues. Note! The default
password for the RAVE is “qsc” (no quotes, lower case).
1- Turn off the computer and unplug the power cord from the RAVE 520uz.
2- Connect a CAT-5 crossover cable from the computer’s network interface card (NIC) to the RAVE QSControl jack (example 1, page 6).
3- Reconnect the power cord to the RAVE 520uz (turn it on). Using the RAVE LCD display and controls, navigate the menu to the IP
Address and make a note of it. In steps 12 and on, you will need to change the IP address of the RAVE or your PC.
4- Turn on the PC and start Windows. You must have Administrator rights and be signed on as Administrator in order to install the
QSControl.net program. Ensure you are signed on to the computer as the Administrator.
5- Place the QSControl.net CD-ROM in your CD-ROM drive. The install wizard should start. If not, you can also select Start, then Run
and browse for the file named setup.exe from the CD.
6- The installer queries the computer for available drive space and other information. If required MDAC library (Microsoft) files are not
already on the computer, the library files are installed. You must accept the Microsoft software agreement in order to install the MDAC
library. It may be necessary to reboot the computer after library installation.
7- At the prompt for “Client/Server” selection, keep both Client and Server selected. This will be appropriate for general use.
8- When prompted “Select Installation Folder”, specify the installation directory or accept the default location.
9- You will be prompted to select an installation accessible by everyone (non-secure) or an installation accessible only to you (secure).
Select the appropriate Everyone or Just Me box and continue. Installation proceeds.
10- Reboot only if your computer prompts you to do so.
11- Select Network Connections in the control panel. Select Properties. Right-click Local Area Connection, and view its properties. Highlight the Internet Protocol (TCP/IP) tab and view its properties. You will see an entry field for the IP address. Decide
whether you want to change the IP address of your computer to be similar that of to the RAVE (easiest if you have many RAVE units) or
if you want to change the IP address of your RAVE to be similar to that of the computer. This is a network management decision.
12- Change the IP address of the RAVE (or computer) to be compatible with that of the computer (or RAVE). Typically, this is done by
making the IP address of one of the devices 1 digit different in the last octet (group of digits in IP address). If changing the computer’s
settings, write down the current values, in case you want to revert later.
13- The subnet mask address should be exactly the same for both the computer and the RAVE. The Gateway address should not be
altered as it is not used.
14- After you are satisfied with all your settings, close all open windows and start the QSControl.net program. Select Start, All Programs, QSControl.net, Venue Manager.
15- The login screen should open. The default password is “qsc” (lower case, no quotation marks). Select “Log on to Local Computer”
and click OK.
16-The QSControl.net Venue Manager window will open. A Startup Tips screen will be visible the first time Venue Manager is
launched. Optionally, the Startup Tips screen may be disabled by un-checking the box in it’s lower left corner. It is highly recommended the user become familiar with each of the tips listed on this screen. After reviewing the tip(s), close the Startup Tips screen.
18
Getting Started (continued)
17- Select Device, Add Device, from the menu. A new window will open prompting you to name the device. Name it logically, such
as RAVE 1, or similar. Select the Device Type and select RAVE 520uz. At the Password prompt, enter “qsc” (lower case, no quotation
marks). This is the device password, separate from the software password. The default, in both cases, is “qsc”, but you are free to
change either or both. Enter the IP address of the RAVE and click OK.
18- The RAVE will now appear in the inventory root (left side of screen, first with a red “x”, then a yellow exclamation point, then a normal icon). If the RAVE does not eventually show in the inventory root, check that a crossover cable is used (only for RAVE connected
directly to PC), check the cable connections, verify IP addresses are set correctly, verify Subnet masks are set correctly, and verify AC
power is properly applied to the RAVE.
19- Click on the “+” sign of the RAVE 520uz in the inventory root, then the “+” sign of the Flashed Configs. Click on the config with the
loudspeaker icon. A view of applicable device tabs will open. Click the DSP tab and the current DSP configuration of the RAVE will be
displayed.
20- Right click on the Design Editor icon in the lower left of your display; select “New”. A new window opens; select RAVE 520uz for
the device type.
21- Click on Help to access the software’s Help system. All software operation is covered in the on-line help file.
Operation of the RAVE 520uz is accomplished with the included QSControl.net software. No software
operation is covered in this hardware manual. After installing your software, open the Help file and
follow its recommendations. The software Help file includes the most recent information available
for your RAVE 520uz.

Operation
QSControl Port
The QSControl port operates on a 10BaseT Ethernet network. This port is one of the primary means for connecting QSControl.net to the
RAVE. The port may connect directly to a PC's 10BaseT or 10/100 (auto-sensing or auto-negotiating) network interface card using a
crossover cable. Data from the QSControl port may also pass through network repeaters, network switches and routers. We strongly
recommend the use of network switches to facilitate higher bandwidth and dedicated connections.
CobraNet Port
The CobraNet port operates on a dedicated 100BaseTx (Fast Ethernet) network. The CobraNet port may connect directly to a PC's
100BaseTx or 10/100 (auto-sensing or auto-negotiating) network interface card using a crossover cable for the purposes of configuration when the RAVE 520uz is in the single-wire interface mode. During normal operation (passing audio) the CobraNet port must connect to a 100BaseTx or 10/100 or 10/100/1000 (auto-sensing or auto-negotiating) switch port. Optionally, the RAVE 520uz may connect
to another CobraNet port using a crossover cable. When the RAVE 520uz is operating in the two-wire interface mode (described in following sections), the CobraNet port may be connected to a network repeater. Regardless of the interface mode, all CobraNet audio data
must pass through only network switches or only network repeaters. Combinations of these devices will cause unreliable operation and
are not supported. Likewise, the use of routers, gateways and ATM devices are not supported for the CobraNet audio path.
CobraNet Channel Density
The RAVE 520uz will support the acquisition of up to 32 channels via up to 4 inbound bundles (from the network). Of these 32 channels,
any 16 may be selected to forward to the signal processing chain (DSP engine).
The RAVE 520uz will support the delivery of up to 32 channels via up to 4 outbound bundles (to the network). Of these 32 channels, up
to 24 may be unique (processed individually... or the result of mixed signals from the DSP engine). The remaining 8 channels (if used)
will be copies of other channels.
CobraNet Channel Resolution
All CobraNet audio will be processed internally within RAVE 520uz at 24-bit resolution. The RAVE 520uz may receive any valid resolution off of the network. This is currently 16-bit, 20-bit and 24-bit. Audio via inbound bundles may be in any combination of these resolutions and the RAVE will process the data accordingly. All DACs will process 24-bit audio, though the least significant bits may be zero
filled if the inbound audio format is less than 24-bit resolution.
The RAVE 520uz will support outbound (sourced onto the network) resolutions of 16-bit, 20-bit and 24-bit. The default outbound resolution is 20-bit.
CobraNet Terms and Conditions
Single-wire interface offers the best efficiency and ease of network configuration for most applications. The single-wire interface
requires fewer network ports and less cabling. Single-wire interface refers to CobraNet audio, CobraNet control and monitoring and
QSControl.net control and monitoring using the same network connection. This mode uses the CobraNet connection to provide all data
communications to the RAVE product. In this mode, the port must connect to a 100BaseTx or 10/100 or 10/100/1000 (auto-sensing or
auto-negotiating) link partner. Network repeaters will not be supported and all audio must pass through network switches only. A
QSControl.net Venue Manager PC may connect to the network via a repeater or router.
Two-wire or dual-wire interface offers the greatest versatility in network design. Separate connections allow discrete networks
and offer support for WAN topologies on the QSControl.net-side. Two-wire or dual-wire interface refers to CobraNet audio having a
dedicated network link and QSControl.net control and monitoring having a dedicated network link. In this mode, the two ports (CobraNet and QSControl) must be connected to separate networks. By separate networks, we mean either physically separate hardware or
the use of common hardware with partitioned or segmented network domains such as the use of VLANs, domain bubbles or separate
port clusters. The dual-wire interface may support dissimilar network hardware for the two port connections (see rules above for CobraNet and QSControl port connections).
1 Minute Autosave Timer and Power Cycling
The active configuration has a special feature associated with it. Any changes made to a parameter during operation will start an internal timer which will trigger an automatic save of the configuration data. The save procedure begins after 1 minute of parameter change
inactivity. If the RAVE 520uz is then power cycled, upon restart, the previous settings data will be preserved in the active configuration.

Utility/Diagnostic Functions
SafeMode Switch
Location of Safe Mode switch: The front panel has a small access hole on the left side, just left of the Power indicator. It is not
labeled to help prevent accidental use. The Safe Mode switch can be operated by using a paperclip (or similar item) inserted into
the access hole and pushing.
Safe mode: Use if the RAVE 520uz becomes inoperable (or behaves in completely unexpected ways) after updating
firmware.
If the RAVE 520uz operates in an unexpected way or is not responding to any communications after a new firmware file is
uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the RAVE 520uz that
will enable you to communicate with it.
How to put the RAVE 520uz into safe mode:
1- Turn off the power to the RAVE 520uz by unplugging it from the AC outlet.
2- Depress the Safe Mode switch and keep it depressed while plugging the unit back in (power on).
3- The RAVE 520uz is now in “safe mode”. You may release the switch.
You should now be able to re-establish limited TCP/IP communications with the RAVE 520uz. Once communication has been reestablished, the file transfer can be tried again or the old application file used until the source of the data transfer problem can be
found. Also, QSControl.net WILL NOT communicate with the RAVE 520uz if it is in “safe mode”. You may communicate only using
TFTP, Telnet, or RS-232.
RS-232 Serial Port I/O Interface
The RS-232 connector on the rear panel is used as a serial port input/output (I/O). This I/O port is used for accessing Ethernet/IP
settings, stand alone control capabilities, system “health” data, firmware version information and other related data.
Should any system problems arise, the data that may be accessed through this interface can help to track down the problem. The
most common items that might be used are “Display Network Settings” and “Enter Network Setup”. Many of the remaining selections would typically be used for troubleshooting purposes along with a QSC technical representative prompting you to access particular menu items so the data can be interpreted.
Connection is made using a normal serial cable between your computer’s serial port and the RS-232 port of the RAVE 520uz. Once
properly connected, a “dumb-terminal” program (such as Hyper Terminal, a widely used version on most Windows-based PC’s) is
started and communication established between the PC and the RAVE 520uz.
Following is the basic procedure for starting up Hyper Terminal, naming the connection, specifying the communications settings
and an example of “what you should see” for a text-menu once the communications link has been established. If programs other
than Hyper Terminal are used, you will need to follow your software’s instructions for establishing communications through your
PC’s COM (serial) port.
21
Utility/Diagnostic Functions (continued)
RS-232 Communications Procedure:
1) Connect the RS-232 port of the RAVE 520uz to an unused serial port (COM port) of a PC using a normal (straight-through) serial cable.
2) Open the HyperTerminal program. This program is usually started by clicking the Windows Start icon, selecting Programs, then
Accessories, Communications, and finally, highlighting the Hyper Terminal folder and clicking on its icon.
3) After starting Hyper Terminal, a Connection Description window will pop-up. It will require that you name your connection.
Enter a name for your new connection (example: RAVE 520uz) and click OK to continue.
4) Next, Hyper Terminal needs to know how to “talk” to the RAVE 520uz. This selection depends on which port on your PC the cable is
connected to. Ignore the first three entry fields (phone number information) and go directly to the Connect using entry field and click
on the down arrow for the drop-down menu selection. Select the port the RAVE 520uz is connected to and click OK to continue. The
Properties window should appear next.
5) The Properties window for the selected COM port should now be active. For the Port Settings, use the following information so
communication beteen the RAVE 520uz and the computer is in the same “language”.
Bits per Second: 9600
Data Bits: 8
Parity: none
Stop Bits: 1
Flow Control: Xon/Xoff
Once you have set the properties as outlined, click OK to continue. If all the connections and communications settings are correct, the
main Hyper Terminal window will open.
6) The Hyper Terminal main window will appear next, but blank. Type the letter “h” (for help) and then the “Enter” key. This will
prompt the RAVE 520uz to post its menu text. The “h” key is the Help prompt for the RAVE 520uz. A text menu will appear. This is sent
by the RAVE 520uz and will detail your options and instructions for changing the address information.
From this main-menu you will need to make your menu choices and follow the instructions in the following sub-menus or screens.
Although many of the instructions and tests may not pertain to a specific setup or troubleshooting situation, you may be asked to run
certain tests by a QSC technical representative. The results of these tests will help to troubleshoot any problems.
The most common user item that might require settings to be changed would be the IP address information. This would be useful if the
IP address was inadvertently changed to an unrecognized address and subsequently you were unable to “talk” to the RAVE 520uz over
the network. This situation would require the Display Network Settings and Enter Network Setup items to be accessed for reassigning a valid IP address.
IP ADDRESS ASSIGNMENT- ONLY REQUIRED FOR ATTACHING TO EXISTING NETWORKS! DO NOT CHANGE THE COMMUNICATIONS SETTINGS OF THE RAVE 520uz UNLESS CERTAIN OF YOUR ACTIONS. THE FACTORY-PROGRAMMED IP
ADDRESS CAN BE ACCESSED USING THE FRONT PANEL DISPLAY MENU SYSTEM. RECORD THIS IP ADDRESS SHOULD
YOU NEED TO RETURN TO THE INITIAL SETTINGS.
22
Utility/Diagnostic Functions (continued)
Telnet Access
The RS-232 features can also be accessed via Telnet. The Microsoft Telnet application is a Windows program. Consult Windows
documentation for Telnet information.
Basic procedure for opening a Telnet session:
1- To open the Telnet session- Click START, select RUN, type “Telnet” followed by a space, then the IP address of the RAVE 520uz
you want to communicate with in the text box and click OK.
2- If the address entered was correct and network communications with the RAVE 520uz are successful, the Telnet session should
open.
3- Now you have the same options that are available in the Serial Port I/O (RS-232) interface section.
