Serial Port Interface
One serial port (RS-232) connector is present on the RTM. This connector provides access to the
COM1 serial port from the MPCBL0020 Single Board Computer, which is also routed to the front
panel of the SBC. Both connections are active, but only one can be used at any given time.

The line driver/receiver for the serial port resides on the SBC. The RTM only provides a connector
along with EMI/EMC filtering. The serial port uses an RJ-45 connector, which is located on the
RTM faceplate as shown in

and
provides the pin-out information for this connector.
Because this serial port is the COM port from the MPCBL0020 Single Board Computer, the port is
inactive when the Serial Over LAN feature is activated on the SBC (the serial port data from
COM1 is routed to the Base Interface Gigabit Ethernet adapter in this situation).
