Assembling and RS485 RS422 Signals
The modular plug connector can be assembled by us if pin assignments are provided. The pins of the 4P4C,
6P6C, 8P8C plug connectors are numbered sequentially 1 to 4, 1 to 6, 1 to 8. Pin 1 is on the left when the
connector is viewed with the retention mechanism on the bottom and the cable opening toward the viewer. An
integral 120 Ohm termination resistor can be installed if requested. RS485/RS422 signals are,
