Currently I'm using the NI GPIB-USB-HS to communicate with a YK1600 PM via custom VI's. Last time I used this(2 weeks ago) everything worked well. However, yesterday all communication attempts were unsuccessful. Today, the GPIB device is no longer lided in my VISA resource dropdown in any of my VI's It's listed in MAX and scanning for instuments switches the PM to remote mode. This would lead me to believe the GPIB-USB and PM are still functional.
Any ideas???
