ONNECTORS
The pinout details for the industry-standard panel-mounted connector interfaces on the Rear
Transition Module are provided in the following sections.
RTM ENET A,
ENET B
Connectors
Ethernet ports A and B are available on RJ-45 connectors via the RTM. Both ports will
auto-select 10 Mbps, 100 Mbps or 1000 Mbps, depending on what they are connected to.
Ethernet port A is accessed via the J5 connector and Ethernet port B is accessed via the J6
connector. The pinouts for both connectors are identical and shown below in Table A.36.
RTM RS422
Connector
EIA-422 serial ports are available on an RJ-45 (J4) connector on the RTM. The pin-out for the
two EIA-422 ports follows a Gigabit Ethernet pin-out on an RJ-45, so that a 1000Base- T
Ethernet loopback cable can be used to loop each node's transmit data port to its respective
receive data port. The transmit signals are outputs from the RTM and the receive signals are
inputs to the RTM. The pin-out is shown below in Table A.37.
