Refer to page 68 (rear panel connections) of the manual to locate them and page 72 for proper wiring of the data mode (ACC 1 and/or ACC 2) jacks.įor simple remote control of the rig, you can purchase a cheap patch cord for around $25 that plugs into the remote control jack of the rig and a standard USB port on your computer. When I spent time learning to decode the digital modes, I discovered the ICOM 746 has a few jacks on the rear panel for controlling the rig and sending data. The radio doesn't care what software you're using, its the software itself that has to be configured for the model radio so it knows which commands to send. I have an ICOM 746 (non pro) and it can be controlled with a PC but I'm not at all familiar with the RS-746 software.
