COMMUNICATIONS SETUP
Delta Tau provides communication tools that take advantage of the PCI bus Plug and Play feature of 32-
bits Windows
®
based computers. Starting with MOTIONEXE.EXE version 10.32.00, which is included
in PEWIN32 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 booted 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.
Open MOTIONEXE
and press Setup for the
PCI device desired
The PMAC2 PCI board may 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 its automatically
assigned use through the setup page of MOTIONEXE:
MOTIONEXE
version number
Disable Interrupts
and Dual-ported
RAM if not used
The MOTIONEXE application will look first for PMAC PCI boards on the PCI bus and will assign
device numbers sequentially 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 provided will not require any further change and the process is transparent.
