FACTORY RS-485 TERMINATION SETTINGS
Each DIN-191 and DIN-192 contains internal pin strips for enabling the
internal termination and biasing resistors. Each pc board is clearly marked
with the jumper designators adjacent to each row of pins. The jumper
designators are +1K, 220 and -1K. To enable any resistor, place a jumper
over the pins next to the required designator. The factory switch and
jumper settings are outlined below.
