#187989 - rs422 and termination resistance
Hi all,

I have a query about rs422 termination resistance at reclining end . Usually we use 120ohm for termination resistance. I have a circuit in this value of termination resistance is 5.1k. The distance between driver and receiving end is about 11m and using DB25 connector and only one receiving circuit.

My question is that 5.1k is big. How we will justify 5.1k ohm resistance

Thanks
