I have a brand new ICOM M-803 a dual role transciver (MARINE SSB and HAM). This unit has been designed to use any of a PACOR modems. I have no itentions to follow this road. I want to use WINLINK, PAT, VARA together with my LINUX box.
M-803 has a dedicated 9 pin serial port to connect with a computer. Its pins are as follow:
1 DCD Inputs terminal for carrier detection.
2 RXD Inputs terminal for receive data.
NMEA-OUT NMEA0183 ver 4.10 data output.
3TXD Outputs transmit data.
NMEA-IN NMEA0183 ver 4.10 data input.
4 DTR Outputs data terminal ready signal.
5 GND Connected to ground.
6 DSR Inputs terminal for a data-set-ready signal.
7 RTS Outputs request-to-send data.
8 CTS Inputs terminal for clear-to-send data.
9 NC No connection.
Hi, I am impressed with the speed you responded. This is very quick indeed.
Now, I have another question - how much will this cost digirig + the Serial CAT + ACC cables?
Mark,
Iβd recommend you try building the cable at home or with somebody at your local club.
You can also check with https://hammadeparts.com/ if you prefer to outsource this project.
building cables is OK but I have no idea what end connectors to use where. I assume one cable with have DB9 male and the other will have the round ACC 8 pins but what on the other end of each cable and how one end relates to the other? could you provide a diagram or a sketch?
Re. parts: for prototyping and small scale build I source the components from Amazon/eBay/Aliexpress. For the cable build I typically start with the cable that already has a correct connector on one side. You can look for DB9 cable that has all needed pins wired or TRRS cable.
Re. Digirig configuration: The serial connection being DB9 and using the standard RS-232 pinout I would go with RS-232 configuration for this radio
Mark, I also have an M803 and I am looking at the DigiRig and the Digirig Lite for the radio. I currently have a Pactor but want to switch to using VARA HF. How well did it work for you? Did you make your own cable or find someone to make it?
Thank you,

Thank you for the tip on the IC-736 cable. Since I am not a homebrew tech, what are the options for getting a cable made up for me? I would like frequency control from Vara/Winlink. My GPS signal for the radio is also acquired from the laptop, so I am trying to replicate as much of the Pactor modem connection features between computer and radio as possible.
@K0TX usually recommends https://hammadeparts.com/ for βone offβ customs.
they might be able to assemble a cable for the serial/remote control side.
I wonder if there is any chance to use the Pactor cables adapted to the Digirig plugs for that serial connection? I will be disconnecting the Pactor cables to connect the sound card for VARA use to the ICOM M802 control box.
