Problem with wavelength using HR2000

[charleslyj]

Hello everyone,

I'm using Labview 2010 professional development system with academic lite license with HR2000 from Ocean Optics to get Spectra data.

But when I run the example from driver package, the vi displays spectra data but it cant't get wavelength data.

The PC is very old. The os is Windows XP SP3 in German. I only install Labview 2010, NI-VISA and other requird software.

I think the problem is that "Read from EEPROM.vi" didn't come out the right data. What ever the input "EEPROM Index" is, the output "ASCII Data" is "□□0.00000".

But I don't know how to fix it. And it seems that other users work just fine with "Read from EEPROM.vi". Could you help me with that?

hi

when did you download the driver.

It was updated last week.

But probably your problem has nothing to do with the update.

I once had the same problem and it was due to a bad usb port and once for a win7 pc that let the usb bus goto sleep to save power.

For the first one, change the bus to another usb connector

for the second one change the power settings of the pc to not use powersave on the usb ports.
