Antenna, Serial Cable, & Power
Voice/Data Switch
Be sure that the VOICE/DATA switch is in VOICE position before connecting the power cord. The
VOICE/DATA switch should always be in the VOICE position. The DATA position is for future potential
products.
Antenna
Connect a suitable antenna to the SMA connector. An antenna is supplied with each unit. See chapter one
of this manual for antenna/RF specifications; see chapter three of this manual for more details about
antennas.
Serial Cable
Connect the DB9-to-DB9 cable between the CallFinder’s RS-232 receptacle and a serial port on your
command computer.
Power
Plug one end of the power cord into the device and the other end onto a live power outlet.
Notes
• The PWR LED. The PWR LED lights after power-up.
• Serial-to-USB 2.0 adapters. If your command computer lacks a serial port, then you will need a serial-
to-USB2.0 adapter.
Antenna Power Supply & Connectors
Remove the protective
shipping cover. Attach the
appropriate interchangeable
blade piece to the power
supply module. Connect the
power lead from the power
supply module into the
power connection on the
CallFinder and tighten the
barrel lock. Now, plug the
power supply into your
power source.
Note: Use only the power
supply supplied with the unit.
Use of any other power
supply voids the warranty
and can damage the
modem.
