Dear All,
I am fairly new to the labviw. I have written a program (in labview 7.1) to communicate with Princeton Reserch Systemes Delay generator DG-535 using GPIB. It works fine! however, I have a small problem here. Once I establish the communication to DG535 using labview program it blocks the manual operation of the DG535. Even after I stop the program, I can not access any channels. I have to restart the DG535 to operate it manually and it repeates everytime I try to communicate through GPIB using my vi. I tried closing the labview to see whether the communication is terminated and I can access the DG535 maually but it did not work. Anyone in this forum had the similar problem? whether it is normal or not. If it is not normal then what is the solution to terminate the communication to DG535 via GPIB and reactivate the manual access without retarting the DG535.
Thank you very much in advance.

Dear Dennis Knutson,
Thak you very much for your kind reply and suggestion. I have added GPIB GTL command in my vi and it works fine.
With best regards

What's that GTL command ? My DG535 does not understand it. And theSRS documentation doesn't mension it either.
[Edit] Ok, I understand : the GTL command is not sent to the instrument, instead, it is an adaptator command thet the NI layer intercepts, and that makes it clear the REM line of the GPIB bus.
