4.4 Connectors
The PDx-140-42-SE / TMCM-140-42-SE offers four connectors, a 5-pin power and serial communication
interface connector, an 8-pin input/output connector, a 4-pin motor connector (with PDx-140-42-SE already
connected to the attached motor) and a 5-pin mini-USB connector.

Table 4.2: Connector for power and communication
Mating connector from JST: PHR-5 (housing) and SPH-002T-P0.5S (crimp contact for AWG #30 to 24 / 0.05mm2
to 0.22mm2 wires).
For RS485 and CAN interface option the module contains a 120Ohm termination resistor:
open: no termination resistor
closed: 120 Ohm termination resistor
For early versions of the unit a zero Ohm resistor is already assembled in order to activate the 120 Ohm line
termination on-board. This has to be removed in case the unit is not connected as last / first node in a
network or there is already proper bus termination installed!
