does mag encoder work on jag speed mode?

[mbushroe]

I am trying to set up a Black Jaguar running firmware version 101 using a direct computer serial connection and BDC-COM so that the Jaguar will operate a CIM motor in speed control mode. Currently, I only have an AS5304 magnetic encoder to provide the feedback. I can interface to the Jaguar over the serial interface fine. I can command it to run forward in Voltage mode (reverse seems to through it immediately into error mode). But neither position nor speed mode seem to have any reading. I tried initially connecting A to A, B to B, Index to Index. Then I tried disconnecting B and Index, and connecting the magnetic encoder index to the A encoder input. Still no joy.

The KOP digital encoders are for 1/4 inch shafts, and the CIMs are 5/16ths. I have ordered a larger unit, but all I have right now is the AS5304. I would like to prove out the concept before trying to program the Jaguar into speed mode through the cRIO, so I would rather get the whole thing running on my test set up with direct PC control before complicating the interface side.
