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.

Serial Console (Debug Port)

The serial console gives users a convenient way of connecting to the programmable controllers. This method
is particularly useful when using the computer for the first time. The serial console is also effective for
connecting to the Moxa programmable controllers when you do not know target network settings and IP
addresses.
