Issue with Analog Discovry connection

[dritech]

Hi all,

I just bought a new AD2 and am having trouble connecting it to my laptop. After installing Waveforms 2015 and connecting the device, the attached error message is popping. Any suggestions please? (Note: I am not using external power, but the USB that I am using is high power - black USB port)

I tried the following:

* Re-booted the laptop

-Re-installed Waveforms 2015

*Used another USB cable

*Used different USB ports

Any kind of help would be highly appreciated.

Hello,

Such error indicates insufficient power.

Try using powered USB hub or external 5V supply.

Hi. Is the external supply of the AD2 internally regulated?

The supply that I have is the one with veriable output voltages, which has no regulatod 5v output,

Connected an external supply and problem solved

Can someone please tell me the exact size of the external power jack so I can buy a dedicated power supply?

i know that Digilent have their own power supply, but I am not willing to spend another $45 on shipping alone. Thanks in advance for your help.

For the Analog Discovery 2 auxiliary power supply you need 5V DC voltage supply with at least 2A max current, 5.5/2.1mm connector, positive inner pin.
