USB 6210 - how to divide down counter input for analog timing source

$

Hi all,

 

I've got a problem with my USB-6210 configuration.

I'm kind of new to DAQMX, thus I don't know how to handle this.

 

I've got a setup running, which uses CNT0 from the USB-6210 to read an encoder (A and B)

This Counter signal is used as the timing clock for reading two analog values. So I get two analog values each time the counter value changes.

 

This works fine till now.

 

Our new machine setup has a new very fine resolution encoder (now 1µm, it was 20µm) and is faster then the old one (nearly twice as fast).

 

That leads to problems, because the USB 6210 isn't fast enough to aquire analog values for each counter change.

 

My suggestion is to divide down the encoder signal by using the second (available) counter of the USB 6210.

 

As a result I would like to get the 2 analog values and the counter value each (lets say) 20µm.

 

Could someone point out what I have to do to get this running, please ?!?!

 

I attached my DAQ Handler as it is now. The missing VIs are:

1. a functional global containing the Command Queue

2. a functional global containing the Results Queue

3. an Errorhandler

 

the values recieved for init are stored as default values in the "setup values" control now.

 

Thanks in advance, best regards


Balze
