ARI-500 Automatic Band Switch for ALS-500

Interfacing to Kenwood Radios

The Computer port (CAT) is used to retrieve the frequency of the radio.
When the ARI-500 is first turned on, the "Auto Information" (AI)
command is sent to the radio. This command causes the Kenwood radio
to output the state of the radio (frequency, mode, etc) anytime the state
has changes. The ARI-500 then uses the frequency to determine the
appropriate band and then selects the correct antenna. The diagram
below shows how to connect a Kenwood radio with a DB-9 Com port to
the ARI-500. Note that pin 7 and 8 (RTS, CTS) on the Kenwood port are
connected together. This ensures that the Kenwood will send the status
information to the ARI-500. The Remote port is also found on the back
of the Kenwood which has the amp key line needed for the ARI-500.
There is one second delay from when the status of the radio changes until
it is sent out over the serial connection.
