5.5.5 10/100/1000BaseTx Connectors
Two 10/100/1000BaseTx RJ-45 connectors are located on the rear panel of the standard
version of the CPCI-6115-MCPTM to support Ethernet I/O from the CPCI-6115 SBC. The pin
assignments for these connectors are as follows:
5.5.6 COM1 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:
I2C_CLK - I2C Serial Clock for transition module EEPROM
I2C_DATA - I2C Serial Data for transition module EEPROM
