One other thing we ran into--the PAL has to be on Com1 for Isodat. We
tried to switch one to run off Com2 (changed it in config, etc.), but
couldn't get it to communicate. GC works ok on Com2. If you have two
Pal's on one instrument, use a switch box.
If PalLoader works, then the computer is talking to the Pal and there's
no wiring issue.
