Most of the modern transceivers can be connected by CAT to the ACOM 1200S. This will allow the amplifier
to track the transceiver frequency without any transmission and change the bands automatically when in
OPERATE mode. The cable can be supplied optionally, ordered separately or home brewed according to

Table 2-1 Signals and pin out of the CAT/AUX connector

The CAT connection requires a cable made especially for the ACOM 1200S and your transceiver. If you need
cable wiring diagrams, please, contact your dealer (see Section
Note that some of the connections - to the transceiver's BCD band data outputs and
Band Voltage outputs do not provide an exact frequency data, but only band data. Those
connections cannot be used when ACOM 1200S works together with ACOM 04AT
because the tuner needs to know the exact frequency, not only the band.
