The diagram below illustrates the typical connections that are made for a single-unit XAP 800 system. The default routing settings in the G-Ware Matrix Screen allow the XAP 800 to work out of the box for this type of installation. CHAPTER 2: Installation Hardware Setup Figure 2.1. XAP 800 installation diagram 1100 Installation ~ Hardware Setup Figure 2.2. XAP 800 rear-panel connectors To connect the unit 1. Place the unit in a standard 19-inch rack and attach it securely. 2. If you are using a custom controller for control and status, plug it into the DB25 Control/Status A or B port [D]. If you are using an external RS-232 controller, connect it to the RS-232 port [I]. 3. Wire the inputs and outputs to the XAP 800 using the provided three- The three terminals in terminal Phoenix push-on connectors. These connectors are designed for the Phoenix connector easy wiring; simply insert the desired wire into the appropriate connector correspond with the rear- opening and tighten down the top screw. panel audio contacts (from left to right): + (positive), – (negative), • Inputs 1–8 [B] Mic or line level inputs and (ground). • Inputs 9–12 [F] Line level inputs only • Outputs 1–12 [E] Line level outputs 4. If you are using a ClearOne Remote Panel, wire it to the RS-485 port [C] using the provided four-terminal Phoenix push-on connectors. . 5. Plug in the XAP 800 to complete the installation. The power output [A] will operate at any level between 100–240VAC and 50–60Hz. If you are installing only one XAP 800 and are not connecting it to any other XAP Figure 2.3. Phoenix push-on connector or PSR1212 units, you have completed the hardware installation. Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760 Installation ~ Networking Units 11 Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760 Expansion bus connections Using the Expansion Bus ports (RJ-45), you can connect up to eight XAP 800/400s and 16 XAP TH2 units, where the total number of microphone inputs does not exceed 64. Make connections between units in daisy-chain fashion using the short RJ-45 jumper. If your units are further apart, use category five twisted-pair cable. The maximum distance between interconnected XAP 800/400 or PSR1212 units is 80 feet (24 meters). Expansion bus cable length is calculated between XAP 800s/400s and PSR1212s. The cable connecting a XAP TH2 to the network is included in the cable length between the XAP 800 or XAP 400. For example, if the cable from the XAP 800 to the XAP TH2 is 50 feet and the cable from the XAP TH2 to the second XAP 800 is 50 feet, then the total length between the two XAP 800s is 100 feet which is beyond the maximum 80-foot limit. To create an expansion bus network 1. Plug the expansion bus terminator in the Expansion Bus In connector of the first unit in the network. 2. Connect the RJ-45 jumper cable (or Cat 5 twisted pair cable) to the Expansion Bus Out connector of the first unit in the network and Expansion Bus In connector of the second unit. Continue connecting units in the same fashion. 3. Plug the expansion bus terminator in the Expansion Bus Out connector on the final unit to complete the network connections. If the E-bus network is not connected properly, the front panel LEDs will flash on the units that are physically connected to the network. To correct the problem, check for broken connections and reconnect the expansion bus cables. Figure 2.4. E-bus connection diagram Networking Units ClearOne recommends that the first unit in your E-bus network be a XAP 400 or XAP 800 rather than a XAP TH2. . RS-232 system-wide control can be provided by any unit in the network. . 12 Installation ~ Networking Units Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760 Device IDs Once your expansion bus connections are made (and if you have more than one XAP 800 at a site), you need to set up a unique expansion bus device ID number—a network address—for each XAP 800 on the network. As shipped from the factory, all XAP 800s are set to device ID 0. To assign device IDs 1. Press the front-panel Enter button, then scroll through the menu until the System menu is visible. 2. Press Enter, then scroll through the menu until Device ID is visible. 3. Press Enter, then scroll through the eight (0–7) options. When the desired device ID is visible, press Enter to select it. (You can also set the device ID in the Unit Properties window of G-Ware software see page 25.) 4. Repeat this process for each XAP 800 on the expansion bus network. Mixer mode There are two mixer mode settings: slave (default) and master. A master unit is not required in a networked system and in most installations, all units will be slaves. Master units ignore audio from upstream units. This prevents audio from being received from units above the master unit in the network. However, global control of the system is still maintained by whichever XAP 400/800 or PSR1212 unit is connected to a control device through its RS-...
