Omron RS 232 Ports

Hi guys,

I am looking for a Omron PLC for an application where I have to use use 3 RS-232 ports. I have a CPM2A but it has only 2 ports(after I use the CPM!-CIF01). Is using a CS1 or CJ! my only option to have more than two ports. Can't I connect a port module(if they have anything like that) to the expansion slot of the CPM2A.

Please advice.
