NOTE
Connect the signal common pin (e.g. GND pin on the serial port pin assignment) between each of the
serial device units. For insulated wire (shielding cable) that is used to reduce electrical noise, connect the
cable shield drain wire to the chassis ground.
NOTE
To ensure that wires are securely connected to terminal block connectors, strip 7 to 9 mm of insulation off
the ends of the wires before connecting them to the terminal block.
