10BaseT/100BaseTx Connectors
Two 10BaseT/100BaseTx RJ-45 connectors are located on the rear panel of the CPCI-6020-
MCPTM-01 to support Ethernet I/O from the CPCI-6020. One channel is always routed from
the CPCI-6020, the other is a custom-build option. Enabling this option requires that the proper
zero ohm resistors be installed on the CPCI-6020. The pin assignments for these connectors
are as follows:

COM1 Connector
An RJ-45 connector is located on the panel of the CPCI-6020-MCPTM-01 to provide the
interface to the COM1 serial port. This port is configured as DCE. The pin assignments for this
connector are as follows:
