TM-PIMC-0001 Transition Module COM1 Connector (J9)
An RJ-45 connector is located on the rear panel of the TM-PIMC-0001
Transition Module to provide the interface to the COM1 serial port. The
COM1DIR jumper (J11) is a two position (three pin) jumper that controls
the origin of the serial port. With pins 2-3 jumpered, COM1 from the
MCPN750A SBC is enabled (and thereby disables it on the MCPN750A
front panel connector). With pins 1-2 jumpered, the connector is redirected
to the PMC I/O module 1 (PIM1). Refer to the TM-PIMC-0001
Installation Preparation section of Chapter 1 for specific jumper placement
information. The pin assignments for this connector are as follows:
