Configuring the com ports on the IX / PCA is a little different that older models and make note that the Port that is configurable and the Pin-out of the port has changed.
The Configurable port is now Port 1
To configure port one, you must change both dip switch settings and set the port mode (RS-232 / RS-422 / RS-485) in the Bios settings. The unit is shipped with both Com 1 and 2 set to RS-232 mode. RS-232 uses the standard Pin-out but Com1 as RS-422 or RS-485 is different than older products.
