CP-132UL/CP-132UL-I

Onboard termination resistors can be activated individually for each serial port using jumpers JP1 and JP2. JP1

corresponds to serial port 1. Short the jumper pins to activate the termination resistor; leave the jumper pins

open to bypass the termination resistor.

The onboard DIP switches, S1 and S2, are used to select RS-422 or RS-485 mode for each serial port. On each

bank, switch 1 corresponds to port 1 and switch 2 corresponds to port 2. S2 selects between RS-422 and

RS-485; S1 selects between 2-wire and 4-wire RS-485.
