I've got a loaner cFP-QUAD-510 and connected it today to see how it will work with the cFP_1804 module.
I've got external power wired to the cFP-CB-1 V and C terminals as prescribed.
The first thing I do in my simple VI is to send the Command = 1 to reset the count. This does not appear to be working.
The next read of the counts taken shows 1616969568. This does not change when I do not rotate the 60 PPR encoder.
When I rotate the encoder the counts seems to wrap to 4294967136 and then only the last 4 digits change count, but not steadily and I get 4294967136 showing up quite bit after the encoder counts down by a couple hundred.
What could be causing this? Does the cFP-QUAD-510 work with the cFP-1804 backplane?
