NI USB-6351 X Series and encoder question

[Kiraly]

Hello, I read documents and threads about encoder integration with NI devices, however I would like to have a confirm. Can I connect a Line Driver encoder to a USB-6351 X Series board? The encoder is from Lika http://www.lika.it/eng/prodotti2.php?idprod=44&ID=1. Should I use the push-pull type? Still I've to buy the encoder so I can choose the proper one. Thanks in advance for any answeer. Franco.

Hi Kiraly,

yeah that seems good for your USB device!

Have a nice day!

I've another question about the above encoder. The max output current is 40 mA for each channel. Can I connect directly the A e B channels to the USB-6351 terminals or I must use some resistor? Looking at the "Connect Quadrature Encoders to a DAQ Device" article it seems they can be connected directly. One more question, why the article doesn't connect +VDC to the encoder? I want to power the encoder using +5VDC terminal from the USB-6351 so I should connect both GND and +5VDC.
