Hi Criss, I suggest you run the PAL directly from it's handheld and set your computer software to aquisition only.

My trouble is that I'd like to use 2 trays (1 with the Gasbench, another with the TC/EA). All else is well in that I have gone into configurator, etc. When running a sequence it communicates with the PAL. Unfortunately, I cannot use the predefined trayholder (to use with VT98) by redefining coordinates, as the position offset lies outside the y range. I hope that makes sense. Can anyone guide me as to script in say "Tray3" instead of Tray01 or another way around this?
