DIP Switch Settings

CP-118U has three onboard DIP Switch arrays, each with 8 switches, referred to below and on the

board (see the above block diagram) as S1, S2, and S3. The switches are used to select one of four

serial interfaces—RS-232, RS-422, 4-wire RS-485, 2-wire RS-485—for each of the eight ports.

Note that S3 selects between RS-232 and RS-422/485, S2 selects between RS-422 and RS-485,

and S3 selects between 2-wire and 4-wire RS-485.
