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.
