What you need is a RS232 to RS422 6 channel converter.
the 15 pin DIN connector on the PLC2 is RS422
the PLC2's don't have DH+ the are just DH Data Highway
they are different and can't be interchanged
you can bridge them with the right hardware.

the attached Doc is a pin to pin cable i made and have used for years
you do need all 6 channels on the RS422 cable
the DH communication module connects to the 15 pin programming port
and you can not program them over the DH network you must be connected directly to the programming port
i use the AB PLC2 software
I hope that helps
