CP-132UL V1 (120 x 64.5 mm)

CP-132UL Series boards have four onboard DIP Switches, referred to below as S1-1, S1-2,

S2-1, and S2-2, that allow the user to choose one of three serial interfaces—RS-422,

RS-485 (2-wire), RS-485 (4-wire)—for each of the two ports. Note that S2-1 and S2-2

select between RS-422 and RS-485, and S1-1 and S1-2 select between 2-wire and 4-wire

RS-485 (S1 is only active when S2 is set to ON).

The figures on the following page show you how to use the switches to select one of the

three serial interfaces for each of the board’s two ports.
