Thanks for the responses. Tomasz, I am currently trying to get an 82357B USB/GPIB adapter working, but I am having some problems. I posted this issue as a separate thread, but here's the situation in case you have some insight:
I am trying to use an Agilent 82357B USB/GPIB adapter to connect a desktop PC running WinXP SP3 with an old HP1050. ChemStation A.10.02 is installed on the computer. The IO library on the ChemStation installation disc is version L.02.01. After installing the L.02.01 IO library, and rebooting the computer with the 82357B connected, the computer cannot automatically find the driver, and the "Found New Hardware Wizard" pops up. The instructions that accompany the L.02.01 IO library state that I should install from a list or specific location, and that I should choose the driver to install myself. The problem is that the driver that was presumably installed along with the L.02.01 IO library is not recognized by the wizard and the 82357B does not show up as a device, so I cannot install it manually. The road ends there with L.02.01. However, when I install later versions of the IO libraries (v. 14, 15, 16) the hardware wizard automatically finds the relevant drivers and installs the adapter, and after proper configuration of the adapter (i.e. set card to hp82341, bus address = 30, etc.) and assigning the proper GPIB addresses to the HPLC modules in the ChemStation configuration editor, I get some communication between the computer and the HPLC machine but the system doesn't fully initialize - the autosampler begins initializing when I run ChemStation but then everything stalls without completing initialization, and the software gives me an ALS not found error (...which is odd, because it initialized). It's not clear to me that A.10.02 can even work with these later IO library versions, so it would be nice to try the L.02.01 version if I could just get the hardware installed. This HPLC was working perfectly a month ago before the computer died, and the modules are properly connected via daisy-chained HPIB cables and remote cables.
Any thoughts here would be greatly appreciated. Thanks.
