I'm trying to get RigSync working with my Icom IC-7610. There is no option in the settings for the IC-7610 so I selected the IC-7300 and change the CI-V address of my IC-7610 to 94h (the default value for the 7300). I then set the CI-V baud rate to match the setting in the IC-7610 (19200) and set SDC to 8 Data bits, no parity, and 1 Stop bit. When I try to start the connection, I get "Failed to open cu.usbserial-A906CZ01. Unknown error!" I have tested the serial port connection and settings with another application on my computer.
I am running the MacOS version of SDC on a Mac Mini running MacOS Catalina 10.15.7.
Here is a screen shot of my settings and error.
Thanks in advance for any assistance.
