Has anyone ever worked with communicating through GPIB to the HP 1100 Series (I'm working with the pump but that is not critical.) Do you know the chain of commands in order to Query the instrument? Do they have to be in HEX?
You should be able to either find a driver for this, or go to HPs website (good luck navigating it, its not even close to as easy to use as NI's) to find the answers you are looking for.
Alternatively, you may have to find or request from HP a copy of the programming manual if a driver doesn't exist. It is always good to have the programming manual even if you have the drivers, as the commandset in drivers (especially for HP) is usually incomplete and sometimes even inaccurate.
