4 does not change regardless of the DSP configuration, unless the configuration intentionally adds more delay . The RA VE 522ua also supports the new optional low-latency CobraNet feature that provi des 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 [...]

5 Introduction - Networking the RA VE 522ua The RA VE 522ua has two RJ-45 network connection ports on the r ear panel. One port is labeled "QSControl" and supports standard 10BASE-T Ethernet. The other port is labeled "CobraNet" and supports 100BASE-TX, also k nown as "Fas t Ethernet". In the followi ng sections, we de[...]

6 Third, the RA VE 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 addit ion, the sophistication and scalability of network switches make them i deal for new installation[...]

7 Example #2 - CobraNet X-over mode: This is the simplest connection you can make between the RA VE 522ua and any of the other RAVE/BASI S models. Use a CA T -5 cross- over cable connected between the CobraNet ports of each unit. No network s witch is required. This connection allows audio to pa ss between the two RA VE/BASIS units over CobraNet. C[...]

8 Example #3 - Singl e Wire Interface: Here all QSControl.net and CobraNet traffic shares the sa me single CA T -5 cable between the RA VE 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 netwo[...]

9 Example #4 - T wo-Wire Interf ace (shared network hardware): This example illustrates the T wo-Wire Interface with a managed Et hernet switch. The switch is configured with multiple virtual local area networks (VLANs). Ethernet deliveries can only reach des tination ports belonging to the same VLAN from which it was sourced. The figure shows a se[...]

10 Example #5 - T wo-Wire Interf ace (separate netwo rk hardware): Example #5 is conceptually similar to example #4. The differenc e here is that separate networks are created by providing each l ocal area network (LAN) with its own network switch. Therefore, tra ffic segmentation is physical rather than logical. Ex ample #5 also pro- vides an addi[...]

11 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 or iginal packing material is not available, ensure that the unit is adequately protected for shipment (strong box of appr opriate size, suff[...]

12 Computer Requirements & Software Installation Installing QSControl.net is easy . All you need to do is choose th e folder where the program is to be stored (the default settin g is accept- able for most applications). We recommend your syste m meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor .[...]

13 General Information & Configuration Memories Network The network should be operable and QSControl.net software s hould be installed/running on the system controller computer . CobraNet Connec tion Loss If you are operating with a valid CobraNet network, and the c onnection to the network is disrupted, audio will mom entarily mute , allow- in[...]

14 Connections AC Power Cord Insert the molded receptacle of the AC power cord into th e AC power inlet on the back of the RA VE 522ua. Plug the AC line connector into the AC out- let. The power supply will accept from 100 to 240 V olts AC, 47 to 440 Hertz, without any changes. If a different type of IEC power cord is required than the one supplied[...]

15 Relay Out T wo sets of relay contacts are provided, RELA Y OUT 1 and RELA Y 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 connec[...]

16 LED Indicators (continued) QSControl and Cobra Net Network St atus (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 t[...]

17 LCD Navigation Map Left side butto ns have screen depe ndent functi ons. This read-only screen is the “out o f the box” default display after power up. Th is is the most desired informatio n when first setting up a network sys tem. Once use r moves to a differen t screen, the last screen accessed becomes the new po wer up default. Boot Scree[...]

18 Getting Started This section outlines one of the simpler methods of getting familiar with your RA VE and the QSControl.net software. The goal of this procedure is to get your computer and the RA VE connected and communicating and the QSControl.net software installed and running . After the software is installed and running, refer to the software[...]

19 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 RA VE 1, or similar . Select the Device T ype and select RAVE 522ua. At the Password prompt, enter “qsc” (lower case, no quotat ion marks). This is the device password, separate from[...]

20 Operation QSControl Port The QSControl port operates on a 10BaseT Ethernet network. This por t is one of the primary means for connecting QSControl.net to the RA VE. The port may connect directly to a PC's 10BaseT or 10/100 ( auto-sensing or auto-negotiating) network interfac e card using a crossover cable. Data from the QSControl port may [...]

21 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 in to the access hole and pushing. Safe Mod[...]

22 Utility/Diagnostic Fu nctions (continued) RS-232 Communications Procedure: 1) Connect the RS-232 port of the RA VE 522ua to an unused serial port (COM po rt) of a PC using a normal (straight-through) serial cable. 2) Open the HyperT erm inal program. This program is usually started by clicking the Windows Start icon, selecting Programs , then Ac[...]

23 Utility/Diagnostic Fu nctions (continued) T elnet Access The RS-232 features can also be accessed via T elnet. The Micros oft T elnet application is a Windows program. Consult Windows documentation for T elnet information. Basic procedure for opening a T elnet session: 1 - T o open the T elnet session- Click ST ART , select RUN , type “T elnet[...]
