5.5.6COM1 And COM2 Connectors (MXP Version)

Four RJ-45 connectors are located on the panel of the MXP version of the CPCI-6115-MCPTM to provide the interface to the COM1 and COM2 serial ports originating from the CPCI-6115 SBC. The CPCI-6115 only supports two serial ports, COM1 and COM2.

The COM1DIR jumper is a two position (three pin) jumper which controls the origin of the serial port. In one position, COM1 from the CPCI-6115 is enabled (and thereby disabling it on the CPCI-6115 front panel connector). In the other position, the connector is redirected to the PMC I/O module 1. The COM2DIR jumper is a two position (three pin) jumper which controls the origin of the serial port. In one position, COM2 from the CPCI-6115 is enabled. In the other position, the connector is redirected to the PMC I/O module 2.

The pin assignments for this connector is as follows:
