RS-485 TERMINATION & BIASING SETTINGS

Proper termination and biasing of any RS-485 based system can be performed by properly enabling the correct resistors inside each DIN-191 or DIN-192. Figures 3.0 and 4.0 show the location of the jumpers on the printed circuit board. The jumpers are shown in their factory set locations to enable the selected resistors. Insert or remove the jumpers as required to properly terminate any RS-485 system.
