How do I get my HP 9852A to work with my GPIB-USB device

[MSU Researcher]

I have an HP 3852A DAQ, and recently I purchased a NI GPIB-USB-HS with NI 488.2 in order to connect it to my laptop.  My problem is I am not able to see or communicate with the device.   I am able to recognize the cord, and I can use the cord successfully with other instruments, but it does not see the HP DAQ.  I was trying to communicate in MAX. Any suggestions??

Hi MSU Researcher,

Many times, problems with finding instruments can be due to settings on the instruments preventing external communication, so check in the 3852A manual to see if there are any settings such as "allow GPIB communication".  Also, check if the instrument has settings for it's address - if so, make sure that this is different from the address of the GPIB-USB-HS.

Thank you very much for the help. I am now able to communicate with the 3852A. I was able recognize the device but could not ID it at first.  I had to use "communicate with instrument" in MAX and adjust the ID command to the 'IDN?' in order to get it to identify itself. 

I unfortunately am still struggling with getting the drivers to run I've downloaded from the NI website below.  I am not able to get a response from the machine when runnin them in labview. If you have any ideas or places to look for a solution I'd appreciate it, thanks.

Hi MSU Researcher,

Try using a simple VISA write and VISA read to see if you can do simple communication with the instrument.  If this works, I would recommend looking at the examples that come with the driver (they will be either in the driver pallette or in the example finder, located in help»find examples).  If the VISA calls do not work, make sure that all of the settings are configured correctly in MAX as specified in the instrument documentation. Good luck!
