2.5. Connecting to External Devices (transceiver, computer, etc.)
a) Amplifier's CAT/AUX interface connector
Please, see Figure 2-3 | Amplifier rear panel - Connections, Pos. 1.
CAT/AUX interface is used for connecting and operating with various transceiver models (see Table 2-2 |
Signals and pin out of the CAT/AUX connector below and the respective menu in Section 5.3 Menu CAT
SETTINGS, Table 5-1 | Transceiver interface type and command set selection and Figure 5-7 | Menu CAT SETTINGS).
Most of the modern transceivers can be connected by CAT to the ACOM 2020S. This will allow the amplifier
to track the transceiver frequency without any transmission and change the bands automatically when in
OPERATE mode.
The CAT cable can be supplied optionally, ordered separately or home brewed according to Table 2-2 |
Signals and pin out of the CAT/AUX connector and also the transceiver's manual.
NOTICE
The CAT connection requires a cable made especially for the ACOM 2020S and your
transceiver. Using an inappropriate cable may cause a serious damage to the amplifier
and your transceiver!
If you need cable wiring diagrams, please, see our document ACOM CAT cables
Technical Information (freely available as PDF-file at www.acom-bg.com), or contact
your dealer (see Section 1.3 Owner Assistance).
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.
Besides the RS-232 and TTL compatible serial interface, the CAT connector also carries
the KEY-IN and KEY-OUT lines, which can be used instead of using separate cables for
those functions from the transceiver to the sockets of the same names.
