Ameritron RCS-12 Instruction Manual

Interfacing to Yaesu Radios

Yaesu radios output band information using a 4-line BCD format. The band data lines can be found on the

Linear port on most Yaesu radios. Some radios share the CAT port with the Linear port. The radio must

be configured so that the port is in Linear mode or the band data information will not be sent to the RCS-

12. Check your radio's manual to determine proper configuration of the Linear port. The diagram below

shows the connection to the RCS-12. Double check with your radio's manual to ensure the correct

connections for the Band Data.

Interfacing to Kenwood Radios

The Computer port (CAT) is used to retrieve the frequency of the radio. When the RCS-12 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 RCS-12 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 RCS-12. 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 RCS-12. The Remote port is also found on the back of the Kenwood which has

the amp key line needed for the RCS-12. There is one second delay from when the status of the radio

changes until it is sent out over the serial connection.

Since the Radio Control Port is used to get the band information from the radio. The radio must be

switched on first before powering up the RCS-12. Upon power up, the RCS-12 sends the Auto Information

(AI) command to the Kenwood radio. This instructs the Kenwood to send the radio's status information

anytime it changes. Failure to do this will result in the radio not receiving this command and the RCS-12

not detecting a properly connected radio.

Anytime the status of the radio changes, there is a one second delay before the new information is sent

over the serial line to the RCS-12. This causes the switch to appear to respond slowly to the band changes.

This is a result of the delay from the Kenwood radio, NOT the RCS-12.
