Features and Functions
- Monitors "ready to transmit" parallel input signal from antenna
switch and generates "transmit inhibit" output signal to the transceiver
for maximum operating flexibility and anti-hot switching protection.
- Directly compatible with ACOM 2000A automatic HF linear amplifier and
ACOM 2000SW remote antenna switch. Control is compatible with other systems
via inverse BCD output code and RS232 serial input (for a PC or other device).
- Local network capability, compatible with ACOM 2000A automatic HF linear amplifier.
- Antenna number 7-segment LED indicator plus sound alarm.
