How do I hook up a encoder to a PCI-6220 daq

[bmfuller]

I have an encoder with 12 pins:
Ua0
Ua0_
Ua1
Ua1_
Ua2
Ua2_

Up
Up Sensor
0V
0V Sensor

UaS
Vacant
Vacant

I am not sure how the encoder signals get tied to the Daq board and how or if I need to connect something to a clock type input. The Linear encoder company (Heidenhain) is also asking what the measuring step i desire (1 microsec or 5)

Can someone help?

Hi Bmfuller,
That looks like a differential encoder. I would take a look at this KB:

Once you get that working, you'll just need to set up a linear encoder task and use the counters. Here is a good starting point for the connections:

I'm not sure what they mean by "measuring step" especially in terms of microsec - did they mention what effect that had on measurements?
Hope this helps,
