I use a TS2000 remotely with Ham Radio Deluxe. You need to do the following:
1. Menu 56 set baud rate to 57600.
2. In your remoterig radio serial setting, use COM2. Set to Mode-4, baudrate 57600, data bit 8, stop bit 1, parity off (leave terminator 00 default), save and reset
3. Do the same on the remoterig control, and set the "use USB COM port as COM2" to yes, so you can use USB cable virtual COM port.
4. Connect USB cable from PC to remoterig control, and check to see you have virtual drivers installed. Reinstall the Microbit Setup manager if necessary again to install virtual drivers
5. In Windows 7 device manager, check to see what com port on your PC corresponds to COM2. You should see something under PORTS: RRC1258 COM2 (COM4) as an example
6. Connect an RS232 9 pin straight cable between the TS2000 and COM2 of the remoterig radio straight cable.
7. Turn on TS2000
7. On your PC, run Ham radio deluxe, and setup a new connection (Connect,new) and select Kenwood TS2000, COM4 (as example), speed 57600.
8. You should be able to connect
The above steps is exactly how mine is setup and in my case works perfectly.
