4 Both software and firmware can be easily updated over the network. In the future, QSC will be adding new capabilities to both RA VE and QSControl.net. Our latest code releases and access to up-to-date information on RA VE and QSCon- trol.net are available at www .
5 Introduction - Networking the RA VE 522aa The RA VE 522aa 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".
6 Third, the RA VE 522aa 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.
7 Example #2 - CobraNet X-over mode: This is the simplest connection you can make between the RA VE 522aa and any of the other RAVE/BASI S models. Y ou use a CA T -5 crossover cable connected between the CobraNet ports of each unit. No network switch is required.
8 Example #3 - Singl e Wire Interface: Here all QSControl and CobraNet traffic shares the same single CA T -5 cable between the RA VE 522aa 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.
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.
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.
11 Unpacking There are no special unpacking precautions. However , it is recomm ended you keep the original packing material for reuse in the rare event that service be required.
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 Amplifier Setup The QSC DataPort-equipped amplifiers connected to the RA VE 522aa must have their power switches in the “on” position. For initi al testing, use the lowest useful gain setting until the system is operating as expected.
14 Connections AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the RA VE 522aa. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240 V olts AC, 47 to 440 Hertz, without any changes.
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.
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 network port and the other for the CobraNet network port.
17 LCD Navigation Map (typical) Left side buttons h ave screen dependent function s. This read-o nly screen is the “out of the box” defa ult dis- play after power up. This is the most desired inf ormation when first sett ing up a net- work system.
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 .
19 Getting Started (continued) 17- Select Device , Add New 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 sele ct RA VE 522aa. At the Password prompt, enter “qsc” (lower case, no q uota- tion marks).
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.
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.
22 Utility/Diagnostic Fu nctions (continued) RS-232 Communications Procedure: 1) Connect the RS-232 port of the RA VE 522aa to an unused serial port (COM port) of a PC using a normal (straight through) serial cable. 2) Open the HyperT erm inal program.
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.
