DIP Switch Settings (CP-118EL only)

CP-118EL has three onboard DIP Switch arrays, each with 8 switches, shown in the table below

and on the listed 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 S1 selects between 2-wire and 4-wire RS-485.
