Slc 500, Termibnate Resistor

Which terminals on the 1784 KXTD card I should connect the 82 ohms resistor to the DH 485 network for the SLC500. I am using 1747 AIC link coupler for the system, I want to add one more control station to the system. I mean the the CH1C 123456

Thanks!

Read the manual.

for sure if the manual has the answer, I know the terminal 6 is the one.

DH-485 is terminated with jumpers. You don't have to add your own resistors.

The user manual shows the proper termination jumpers between terminals 5 and 6 on both ends, and between 1 and 2 on just one end for the shield.
