Paul i am working on encoder mount now and will mount it the same way as resolver is mounted. Now since i have open collector A, B, Z signals i will have to pull them up to 5V with resistors. Can you suggest R value? I see you use 1K resistors to protect micro pins. Do i use 1K also, or could i use 4.7K. Or should i rather use 470R to make ports react faster? Or would you recommend changing input resistors from 1K to 470R?
RLS has 20mA draw limit for their encoder chip.

tnx

Arber
