Hi Kirk, A couple of things.
The ModIO I sent you has a RS232-485 converter built in. With this you can run a serial cable from the ModIO to the PC, then run additional Modbus devices from the RS485 terminals on the ModIO. It saves from needing an external converter. When using RS485 I recommend using full duplex rather than 1/2 duplex. Some times there are issues with buffers in the PC and timing for switching the transmission direction Cheers, Peter.
