Transmit and Receive Antennas
The TNC transmit jack and receiver jack are both labeled on the
rear of the unit. The base station comes with two (2)
1/2-wave antennas. Always match the color dot on the rear
panel of the base station with the colored band on the antenna.
2-Wire Intercom Ports
The base station has the ability to interface with two (2)
2-wire external audio intercom systems. These XLR jacks are
designated intercom 1 and 2 on the rear panel.
They accept Telex, RTS, and Clear-Com types of intercom
systems. The pinouts of these standard types of intercom are
shown in Figure 19.
The base station does not require wet intercom lines for
operation. Wet intercom lines are those with D.C. voltages on
them for powering 2-wire devices. The base loops through wet
intercom lines with currents up to two (2) Amps.
WARNING:
Do not loop through more than two (2) Amps
of current. Damage to the base station may
result.
