The CP-114 board has one female DB37 connector on the board. To
connect the board to your serial devices, you may make your own cable,
or use one of the two cables available from Moxa. In the following
figures, we give the pin assignments for the DB37 port on the board,
and the pin assignments for the serial device side of the two connection
options.
