Introduction  
The RAVE 522ua provides the digital audio transport, and  
no longer required on that system’s network. All basic func-  
tions of the RAVE 522ua continue to operate with or without  
a control computer connected to the network.  
signal processing needed to bind a group of amplifiers and  
loudspeakers into an integrated functioning system. In con-  
junction with QSControl.net software, the RAVE 522ua  
enables the user to design, test and deploy professional  
audio reinforcement and distribution systems ranging in size  
from one to hundreds of channels.  
The configurable DSP engine provides all of the functions  
necessary to handle the amp/loudspeaker portion of a sig-  
nal chain, such as very flexible and precise crossovers,  
delays, equalization, compression/limiting, etc.  
A standard Windows computer is the principle user-inter-  
face for controlling the overall RAVE/QSControl system.  
However, the RAVE 522ua also offers a front panel interface  
for accessing critical functions.  
Audio enters a RAVE 522ua 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.  
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.  
Unlike many configurable DSP boxes, the intrinsic process-  
ing latency of the RAVE 522ua is both short and fixed at  
0.396 milliseconds. When analog input and analog outputs  
are used, the total delay is 2.354 milliseconds. The delay  
The QSControl.net network can also be managed from a sin-  
gle computer running both the client and the server. Once all

the configuration intentionally adds more delay.  
The RAVE 522ua also supports the new optional low-latency  
CobraNet feature that provides transport at only 2.66 milli-  
seconds delay. Thus the delay from analog to analog across  
the network can be less than 6 milliseconds, fast enough  
not only for large audio distribution but for the most critical  
real-time live performance work.  
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 522ua brings all that technology  
together in one compact, powerful, easy to use system. We  
are confident that your new RAVE 522ua will provide years  
of dependable service and we hope it will help you, the sys-  
tem designer and implementer, to express your creative  
audio system ideas.  
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

Introduction - Networking the RAVE 522ua  
The RAVE 522ua 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 522ua supports two distinct kinds of network activity; the first is audio transport via CobraNet, and the second is QSCon-  
trol.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 QSControl.net data and audio traffic 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 appli-  
cations, separate networks won't provide any discernible benefits and will cost more. We therefore recommend using the Single Wire  
Interface when running CobraNet.  
If your application uses only analog I/O without CobraNet, then you should use the QSControl port for QSControl.net traffic and ignore  
the CobraNet port.  
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, Cobra-  
Net 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.  
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 criti-  
cal 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 522ua Single Wire Interface, which offers a solution for converging audio and QSControl.net onto the same LAN or VLAN. How-  
ever, 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 522ua. In fact, common network hardware, such as managed Ethernet switches  
and media converters, can service both RAVE 522ua products and conventional data communications equipment so long as the man-  
aged 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 522ua 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 con-  
nected 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 522ua 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 522ua. 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 lim-  
ited 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 522ua 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 var-  
ious networking devices. Most of the time it "just works". QSC helped pioneer CobraNet with our RAVE ™ products and there are hun-  
dreds 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 network-  
ing…  
Example #1 - QSControl.net X-over mode:  
This is the simplest connection you can make between the RAVE 522ua and your computer. Use a CAT-5 crossover cable connected  
between the RAVE QSControl port and your computer's Network Interface Card, (NIC). No network switch is required. With QSCon-  
trol.net server and client software installed and running on your computer you will be able to completely set up your RAVE 522ua.  
6
Example #2 - CobraNet X-over mode:  
This is the simplest connection you can make between the RAVE 522ua and any of the other RAVE/BASIS models. Use a CAT-5 cross-  
over cable connected between the CobraNet ports of each unit. No network switch is required. This connection allows audio to pass  
between the two RAVE/BASIS units 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 connec-  
tions - 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  
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 avail-  
able 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 522ua 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 two RAVE/BASIS units, as many devices may be connected as there are available switch ports. All  
units will be able to communicate simultaneously with the computer. All will have access to CobraNet audio. Switches can be con-  
nected to other switches to build larger networks; all of the normal networking principles apply. (Note: there must be at least two  
CobraNet devices, one source and one destination, online 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 config-  
uration essentially provides a dedicated network for QSControl.net (including the system controller) and a second dedicated net-  
work for CobraNet audio. As with the previous example, as many units may be connected as there are switch ports available. All  
RAVE units will be able to communicate with the computer. All will have CobraNet audio. 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 pro-  
vides an additional level of fault tolerance, although at the expense of additional network hardware. The figure shows a separate net-  
work 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  
QSCs Technical Services Department for packing material and a carton.

Mounting  
The RAVE 522ua 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 522ua 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 522ua 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 522ua’s chassis includes integral rear mounting tabs for securing to the rack mounting ears.

Computer Requirements & Software Installation  
Installing QSControl.net is easy. All you need to do is choose the folder where the program is to be stored (the default setting is accept-  
able for most applications). We recommend your system meet the following minimum requirements:  
1- IBM PC compatible computer with a Pentium 4 processor.  
2- Processor speed of 1 GHz (2 GHz or faster recommended for systems with 30 or more BASIS/RAVE/DSP units).  
3- 512 megabytes of RAM (1 gigabyte recommended for systems with 30 or more BASIS/RAVE/DSP units).  
4- Hard drive with at least 500 MB of free space for the program and files you generate.  
5- Display resolution of 1024 X 768, 16-bit color.  
6- CD-ROM drive to install the software.  
7- 10BaseT/100BaseTx network interface card  
8- Windows XP Professional, XP Home, Windows 2000 SP2 (or better), or Windows NT4.0 SP6a operating system. Windows 95,  
98 and ME platforms are not supported.  
Note: If system is used for real-time adjustments and configuration of audio systems, we recommend all Windows Power Options  
(located in the Windows Control Panel) features be disabled. Display, hard drive, system standby and hibernation settings should be set  
to “Never”. This avoids waiting for the system to “wake-up” if adjustment is needed after an elapsed period of time.

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, allow-  
ing the RAVE 522ua to synchronize with its internal clock. If CobraNet network connection is re-established, the audio will mute again  
while the RAVE 522ua synchronizes with CobraNet.  
Configuration Memories  
The RAVE 522ua has non-volatile storage locations that contain settings for the device as well as DSP signal flow. The storage loca-  
tions 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 522ua. Plug the AC line connector into the AC out-  
let. 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 522ua, 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 522ua 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.

the lock-tab oriented toward the bottom of the RAVE 522ua 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 audio input and out-  
put- balanced connection.  
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.

Relay Out  
Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT  
2. Contacts are floating and rated for 30VDC, 1A. There is one common  
terminal, one normally-closed contact terminal and one normally-open  
contact terminal. These are labeled as C, NC and NO on the rear panel.  
When the relay is not energized, the C terminal is connected to the NC  
terminal and the NO terminal is not connected; when the relay is ener-  
gized the C to NC connection is opened and the C to NO connection is  
closed.  
Relay Out connections.  
Refer to text, at left, for  
explanation.  
RS-232  
The RS-232 is a utility serial port for accessing certain diagnostic fea-  
tures and setup. Connect to an available COM port on your PC and com-  
municate 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 522ua. 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 522ua is plugged into a properly functioning AC outlet,  
it will power up and briefly display a welcome screen on the LCD dis-  
play.  
POWER Indicator- This blue indicator illuminates when the RAVE  
522ua is plugged into a properly functioning AC source. There is no  
power switch on the RAVE 522ua. This helps to prevent accidental sys-  
tem shutdowns.  
DIAGNOSTIC Indicator- This red diagnostic LED reports several pos-  
sible operational conditions. During boot-up, it is used to continually  
blink a “dot-dash” pattern if the power-on memory self-test fails. Dur-  
ing 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.

LED Indicators (continued)  
QSControl and CobraNet Network Status (Port) Indicators- There are three 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 func-  
tions 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 522ua receives data from the corresponding network.  
TX (transmit)- This indicator illuminates whenever the RAVE 522ua transmits data onto the corresponding network.  
LINK STATUS- The corresponding indicator illuminates when the RAVE 522ua is connected to an operating network.  
SIGNAL indicators- These indicators will illuminate green for input signals -40dB to -10dB below full scale; yellow for sig-  
nals between -10dB to -2dB below full scale; red for -2dB to full scale (or clip).  
LCD Display and Controls  
The RAVE 522ua 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 522ua 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” checkbox in the Front Panel Password menu of the  
QSControl.net software.

Use rotary data wheel to edit data. Rotate to  
move cursor and push to accept change.  
LCD Navigation Map  
Boot Screen  
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.  
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 522ua.  
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 522ua (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 proper-  
ties. 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 Pro-  
grams, 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 recom-  
mended 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 522ua. 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 nor-  
mal 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 522ua 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 block 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 522ua 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 522ua 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 522ua.  
19  
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 configura-  
tion when the RAVE 522ua is in the single-wire interface mode. During normal operation (passing audio) the CobraNet port must con-  
nect to a 100BaseTx or 10/100 or 10/100/1000 (auto-sensing or auto-negotiating) switch port. Optionally, the RAVE 522ua may connect  
to another CobraNet port using a crossover cable. When the RAVE 522ua is operating in the two-wire interface mode (described in fol-  
lowing 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 522ua 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) in any one configuration.  
The RAVE 522ua 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 522ua at 24-bit resolution. The RAVE 522ua may receive any valid resolu-  
tion 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 resolu-  
tions 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 522ua will support outbound (sourced onto the network) resolutions of 16-bit, 20-bit and 24-bit. The default outbound resolu-  
tion 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 (Cobra-  
Net 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 Cobra-  
Net 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 inter-  
nal 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 522ua is then power cycled, upon restart, the previous settings data will be preserved in the active configuration.

Utility/Diagnostic Functions  
Safe Mode 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 522ua becomes inoperable (or behaves in completely unexpected ways) after updating  
firmware.  
If the RAVE 522ua 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 522ua that  
will enable you to communicate with it.  
How to put the RAVE 522ua into Safe Mode:  
1- Turn off the power to the RAVE 522ua 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 522ua 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 522ua. Once communication has been re-  
established, 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 522ua 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 selec-  
tions would typically be used for troubleshooting purposes along with a QSC technical representative prompting you to access par-  
ticular 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 522ua. Once  
properly connected, a “dumb-terminal” program (such as Hyper Terminal, a widely used version on most Windows-based PCs) is  
started and communication established between the PC and the RAVE 522ua.  
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 522ua 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 522ua) and click OK to continue.  
4) Next, Hyper Terminal needs to know how to “talk” to the RAVE 522ua. 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 522ua 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 between the RAVE 522ua 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 522ua to post its menu text. The “h” key is the Help prompt for the RAVE 522ua. A text menu will appear. This is sent  
by the RAVE 522ua 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 522ua over  
the network. This situation would require the Display Network Settings and Enter Network Setup items to be accessed for re-  
assigning a valid IP address.  
IP ADDRESS ASSIGNMENT- ONLY REQUIRED FOR ATTACHING TO EXISTING NETWORKS! DO NOT CHANGE THE COM-  
MUNICATIONS SETTINGS OF THE RAVE 522ua 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 522ua  
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 522ua 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.
