How to connect incremental encoder to NI9411?

[byrd]

Hi,
 
I have to connect an incremental encoder to a NI-9411 digital input module on a cRIO chassis to use for high speed triggering.  I am having some trouble figuring out how to hook the necessary wires from the encoder up to the 9411 correctly.

The wires carry the following signals:
 
A-Red
B-Green
Z-Brown
+V-Blue
OV-Orange

I'm pretty inexperienced with connecting sensors to LabVIEW gear, so please let me know if I can supply more info about my setup.

Also, attached is the datasheet for the encoder. 

Thanks a lot!

Hi Byrd,

Thanks for the post and I hope your well today.

I am afraid Im not fully sure what your issue is.

The NI 9411 Manuals can be found here:for extra reading.

The operating instructions  covers how to connect Single-ended devices to the 9411.

page 12: 

"An example of a single-ended device is a single-ended encoder. Connect each of the signals of the encoder (phase A, phase B, and
index) to one of the pins in a pair of DI pins. Figure 5 shows the connections for one single-ended encoder."

In labVIEW you can then create a DAQmx task to read all the digital lines.

Hope this helps to get you started,

Thanks for the reply.  Looking at the diagram you noted helped a lot and I got the encoder working!

Thanks again,

Alex
