supply from the RS-232C cable is OFF (while the host power supply is
OFF).
NT31/NT31C side for communications with the host, but in this case one
NT-AL001 Adapter is required for each NT31/NT31C. In this case, it is
convenient to use serial port A of the NT31/NT31C. +5 V is not output
from serial port B.
