Power requirements

The XAP TH2 automatically accommodates voltage requirements of 100–240VAC,
50/60Hz, 15W.

Telephone line requirements

The XAP TH2 model operates on a standard analog telephone line and connects to
the telephone system with a standard RJ-11C modular jack. If you do not have an
RJ-11C jack where you want to install your XAP TH2, call your telephone company
for installation.

The XAP TH2 can be configured to meet compliance requirements of different

countries via the G-Ware software. See page 12.

Equipment placement

The XAP TH2 models are designed for installation in a standard 19-inch equipment
rack.You can also purchase side panels for desktop placement.

Network requirements

The expansion bus (RS-485) lets you connect up to eight XAP 800/400s and 16
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.

Environmental requirements

The XAP TH2 can be safely operated in a room with varying temperatures between
32 °F (0 °C) and 110 °F (43 °C).

Before You Install

Warning: The country

code must be set

correctly in
G-Ware to ensure that the unit
operates properly when
connected to the telco network
and complies with the country’s
telco requirements. Changing
this code to a country other than
the intended country of
operation might cause the XAP

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

3. Plug your telephone set into the RJ-11C Set jack [C].

4. If you are using a custom controller for control and hybrid status, plug it
into the DB-25 Remote connector [I].

If you are using an external RS-232 controller, connect it to the
RS-232 port [H].

5. Wire the XAP TH2 to the XAP 800 using the provided three-terminal
Phoenix push-on connectors.These connectors are designed for easy wiring;
simply insert the desired wire into the appropriate connector opening and
tighten down the top screw.

• Transmit Input Audio connected to the Transmit Input [D] will

be sent down the telephone line.

• Receive Output Audio from the telephone participant is

passed to Receive Output [E].

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
network device locations that can be selected (0-F). As shipped from the factory, all
XAP TH2 units default as binary address 0.

Set Device ID numbers for each XAP TH2 unit at your site by manipulating

rear-panel DIP switches 1–4 [F], selecting/deselecting each switch to set up
address 0–15 in binary code.The table on the following page illustrates DIP switch
settings. DIP switch changes are read only when the unit is powered up, so you will
need to power cycle the unit to have the changes recognized.
