Hello,
I've just seen your post about an ISA card. I know it was posted in 2003 but there
were no replies. The card is possibly a BMS (Building Management System) controller card.
It is installed in a PC and runs an operating system called OS9. It then communicates with
a BMS outstation via an RS244 interface. I hope this information will be of some use to
you.
Best regards,
Graham Harvey
