Table 5.1 TMCM-3314 interface brick: connectors and mating connectors
5.1.1 RS485 connector
There are two RS485 connectors on the board with the same pin assignment – pins directly connected to each
other. The second connector may be used for attaching a bus termination resistor to the RS485 bus (there is no
termination resistor on-board) or for further distribution of the RS485 bus signals to other RS485 communication
nodes while maintaining a proper bus structure.
A three pin Molex MicroFit™ connector (Molex part no. 436500315) is used for RS485 connection. Mating connector
housing e.g. Molex 43645-0300, contacts Molex 43030-0007. Please note that there are alternative options available
from Molex for both, housing and contacts.

5.1.2 CAN connector
There are two CAN connectors on the board with the same pin assignment – pins directly connected to each
other. The second one may be used for attaching a bus termination resistor to the RS485 bus (there is no
termination resistor on-board) or for further distribution of the CAN bus signals to other CAN nodes while
maintaining a proper bus structure.
A standard RJ45 plug connector is used for CAN communication. Standard CAT cables (e.g. CAT 5, non-crossing)
might be used for connection. Pin assignment of the RJ45 is based on the CiA 303-1 recommendation.
