You may use a male 9-pin D-to-bare-wire RS-232 cable or a universal
control cable (UC 50', UC 100', or UC 200') for the connection to a computer
or control system. One end of the UC cable is terminated with a female
9-pin D connector, and the other end is unterminated. The UC cable's
pin assignments are as shown in the following illustration. Refer to the
computer/control system's pin assignment guide to determine which of the
cable's wires to connect to which of the MLS's RS-232/MLC/IR port pins.
