If the MSW is to be used as a remote
control for a computer or host controller,
connect a 9-pin HD connector to a
computer, then connect a 5-pole captive
screw connector to the RS-232 port ( ) on
the mini switcher. Protocol for this port is
9600 baud, 8 data bits, 1 stop bit, no parity.
Wire the connector as follows: Pin 2 = Tx,
Pin 3 = Rx, Pin 5 = Gnd. Refer to figure
3 or see “Serial Communication” in the
user’s manual for more information.
