based computers. Starting with MOTIONEXE.EXE version 10.32.00, which is included in
Pewin 32 version 2.32 and newer, a PMAC2 PCI board plugged in a PCI bus slot will be recognized by
the operating system when the computer is boot up. The available PCI address, dual-ported RAM address
and Interrupt lines are set automatically by the operating system and can be checked (but not modified) in
the MOTIONEXE.EXE application.
The PMAC2 PCI board could have the optional on-board Dual Ported RAM circuitry, which is ordered
through Option 2. If the dual-ported RAM circuitry is not on-board, manually disable the automatically
assigned use through the setup page of MOTIONEXE:
The MOTIONEXE application will first look for PMAC PCI boards on the PCI bus and will sequentially
assign device numbers from Device0 to each PMAC PCI until all the PMAC PCI boards found have a
device number assigned. Then, manually add other devices for either ISA bus or Serial port
communications.
After each PMAC has a device number assigned to it, communications through the PCI bus are identical
to the ISA bus. Any application written for the ISA bus using the Delta Tau provided 32-bits
communication libraries will not require any further change and the process is transparent.
