Dual Icom IC706 and IC746PRO control
« on: 2014-05-17, 19:56:41 »
I have my remote site linked for a remote control head operation with the IC-706 radio. Everything is working perfectly. Just like being there.

However, I would like to add a secondary and independent CI-V control link for CI-V CAT control of a separate IC-746PRO at the same site. At first blush, it would seem that I could use either unused COM port (COM1 or COM2) in a "serial server" mode. In other words, connect a CAT program to COM1 locally and a Serial to CI-V adapter to the COM1 port at the remote site to provide CAT control of the IC-746.

I have tried both COM1 and COM2 without any success. I am asserting CTS/RTS in case the adapter needs power from those leads.

Is this mode of operation using a Serial to CI-V adapter even possible? Any hints or suggestions would be appreciated.

You must use a CI-V interface which is powered from a separate source like the CT-17. Pirate interfaces powered from the serialport cannot be used.

Thank you for that hint Mike. I will try that.

Since the connector on the RemoteRig unit is female and the CI-V to serial adapters are expecting a typical male connection, would I also need a NULL modem or Null modem cable to connect?

Thank you Mike. Just received my (self-powered) CT-17 and all is working fine now.

A null modem IS required for proper connection (at least for COM1).
