    XAP TH2 units, where the total number of microphone inputs does not exceed 64. The maximum distance between interconnected XAP 800/400 or PSR1212 units is 80 feet (24 meters). Insertion of a XAP TH2 must not increase the cable length between two PSR1212s, XAP 800s and/or XAP 400s beyond 80 feet. ClearOne recommends that category five twisted-pair (10BaseT LAN) cable be used.

    CHAPTER 2: Installation Hardware Setup The XAP TH2 is designed for easy installation and setup. All connections are made through rear-panel connectors. This section provides instructions on installing the units in the rack and making initial connections, assigning device ID numbers, and creating an expansion bus (E-bus) network.

  • Page 13: Assigning Device Id Numbers

    Assigning device ID numbers Before creating an expansion bus network, you need to set up unique expansion bus Device ID numbers for each XAP TH2 on the network. There are 16 expansion bus If more than one XAP TH2 network device locations that can be selected (0-F). As shipped from the factory, all is assigned the same device XAP TH2 units default as binary address 0.

    CHAPTER 4: Operation The XAP TH2 has four basic functions: make a call, answer a call, disconnect a call, and mute. This chapter explains how to perform these functions with the TH2 unit and a telephone handset (optional) and with the Dial interface in G-Ware. You can also use touch panels and custom control devices.

    CHAPTER 5: Optimization Adjusting Levels In order to optimize the audio levels, you will need to place a call on the XAP TH2. This will enable you to evaluate the levels for caller audio, audio being sent to the telephone, dial tone, DTMF tone, audible hook indication, and audible ring indication.

  • Page 27: Adjusting Transmit Audio

    To increase or decrease audio being sent to the telephone line, adjust the output gain on the XAP 800 output channel that is connected to the XAP TH2 Transmit Input. This will affect only the audio being sent to the telephone on that channel. See the XAP 800 manual or G-Ware help file for detailed instructions.
