Caution! * ESD
A single static discharge can damage your card and cause
premature failure! Please follow all reasonable precautions to
prevent a static discharge such as grounding yourself by touching
any grounded surface
prior to touching the card.
Hardware Installation
1.
Do not install card into the computer until the software has been fully installed.
2.
Turn OFF computer power AND unplug AC power from the system.
3.
Remove the computer cover.
4.
Remove the two (2) nuts retaining the strain relief brackets from the card, set one bracket
aside with the nuts.
5.
Select an available location to install the card in an available 5V or 3.3V PCI expansion slot
(you may need to remove a backplate first). DO not plug the card in
to the slot yet…..
6.
With the card in your hand or on the bench, feed ribbon cable(s) through the selected
computer backplate one at a time and plug onto the card header, starting closest to the
mounting bracket. When all cables are installed, re-install the strain relief bracket and nuts,
and tighten until snug. DO NOT OVERTIGHTEN!
7.
Carefully plug the card into the slot and inspect for proper seating and fit. Make sure that the
card mounting bracket is properly screwed into place and that there is a positive chassis
ground.
8.
Make connections from installed ribbon cables to the field equipment / wiring.
9.
Check all connections and installations to ensure the system is ready to be turned on.
Do not
turn on field power before turning on the computer as all outputs on the card will be
ON.
10.
Replace the computer cover and turn ON the computer which should auto-detect the card
(depending on the operating system) and automatically finish installing the drivers.
11.
Run PCIfind.exe to complete installing the card into the registry (for Windows only) and to
determine the assigned resources.
12.
Run one of the provided sample programs that was copied to the newly created card directory
(from the CD) to test and validate your installation.
13.
Once the card has been initialized and you’re sure the outputs are in a known state, external /
field power may now be turned on if desired.
The base address assigned by BIOS or the operating system can change each time new
hardware is installed into or removed from the computer. Please recheck PCIFind or Device
Manager if the hardware configuration is changed. Software you write can automatically
determine the base address of the card using a variety of methods depending on the
operating system. In DOS, the PCI\SOURCE directory shows the BIOS calls used to
determine the address and IRQ assigned to installed PCI devices. In Windows, the Windows
sample programs demonstrate querying the registry entries (created by PCIFind and
NTIOPCI.SYS during boot-up) to determine this same information.
