Introduction The RAVE 522ua provides the digital audio transport, and signal processing needed to bind a group of amplifiers and loudspeakers into an integrated functioning system. In conjunction 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.
Introduction (continued) does not change regardless of the DSP configuration, unless the configuration intentionally adds more delay. trol.net are available at www.qscontrol.net. We invite you to visit us there. The RAVE 522ua also supports the new optional low-latency CobraNet feature that provides transport at only 2.66 milliseconds delay.
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.
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.
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 crossover 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.
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.
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 QSControl.
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.
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.
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 acceptable 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).
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 522ua to synchronize with its internal clock.
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 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 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.
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 energized the C to NC connection is opened and the C to NO connection is closed.
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 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.
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. Use rotary data wheel to edit data. Rotate to move cursor and push to accept change. Boot Screen Right side buttons serve as up/down navigation.
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).
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.
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.
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.
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.
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.
