need help hooking up encoder

hi all, just got my 2000 series drives and want to hook up my encoder. My encoders are HEDS-9140 encoders. Do i need to use the R2210 - Single ended or TTL, encoder interface or can i just wire the encoder straight to a piece of cat5 cable just for testing? newbie at servos here and getting confused fast...

thats a good question i'd like an answer to that also

check out the r991h datasheet on the rutex site.

according to Tom at rutex you need the R2210 to convert the encoder signals to differential signals, just ordered mine.....
