    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    So would I need to use another Led driver which has enough current to drive the leds?, or would I be better of changing the Leds? Thanks

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    Well I was planning to power the LED driver through the DAQ, but if that won't work how can I power the LED driver? Yes that is what I am planning to do have two outputs for each LED,as it is a bi-colour LED so current will run through each leg of the LED to determine which colour should be...

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    DAQ is being used so that the LEDs can be controlled through LabVIEW, so DAQ works well with that so that is why the DAQ is being used. How will the LEDs receive current in this case which they need to be able to work? I thought the DAQ might provide current as well but maybe I am mistaken, I...

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    here is the datasheet for the DAQ http://www.mccdaq.com/PDFs/manuals/USB-1208FS.pdf Doesn't it say if it's connected through a usb to pc there is 500mA ( under power subheading page : 25 )

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    sorry where exactly on the datasheet does it say it's 20mA ? So is there anything I can do to get the current to drive the 13 Leds? but not all of them will be on at the same time only 1 will be on as the next on in line blinks here is the datasheet for the LED driver...

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    Sorry here is the link for the LED datasheet http://www.rapidonline.com/pdf/55-0168e.pdf is that output current of the analog output from the DAQ? which is 6mA

    Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?

    USB-1208FS supplies 5v I believe so can it supply that much to the LED driver which is running 13 Bi-colour LEDs Thanks
