Can my ProSoft or ProLinx DFCM module communicate through an Allen-Bradley 1747-AIC module?

The 1747-AIC module only converts the signal from RS-485 to RS-232. It does not convert the protocol from DH-485 to DF1, which the DFCM module requires. For DH-485 communications, check the ProSoft website for modules which support DH-485.
