NOTE
1) Recommended maximum cable length is 15m (50ft.). Please note, RFI / EME noise should be
kept to a minimum, communication cable should kept apart from high voltage wires. If a
transmission speed of 38400 bps or greater is required, the maximum length of the
communication cable is 3m (9.84ft.) which will ensure the correct and desired baud rate.
2) The number shown in the pervious figure indicates the terminal number of each connector.
