Figure A-8. RS-285 2-wire Wiring
Verify that the dipswitch on the front of the device is in the down position, indicating RS-485
communications. When configuring for RS-485, termination resistors (120
) are needed at each end of
the network. Note the location of the resistor on the device. The ProTech has the termination resistor built
into the module, jumpers are necessary between terminals 14—15 and 18—19 to activate the
termination.
