Introduction
The PCIDIO 24H/48H/96H series products are general purpose digital I/O cards.
This series includes three cards:
lPCIDIO 24H: 24-CH DIO card
lPCIDIO 48H: 48-CH DIO card
lPCIDIO 96H: 96-CH DIO card
The 48H series products are multi-function digital I/O boards used for
industrial PC with a PCI bus. The cards are plug-and-play,therefore it is
not necessary to set any jumpersfor configuration of I/O address or interrupt
PCIDIO 48H and PCIDIO 96H are 48-channel and 96-channel DIO cards
respectively. PCIDIO 24H is a reduced version of PCIDIO 48H, all the functions
are exactly the same as PCIDIO 48H except there are 24 channels only.
The PCIDIO 48H emulates two industry standard 8255 Programmable
Peripheral Interface (PPI) chips operated under mode zero configuration.
The PCIDIO 96H emulates four PPI chips. These two cards are compatible
not only on hardware connectors but also on software programming.
Every PPI connector offers has 3 ports: PA, PB, and PC. The PC can also be
subdivided into 2 nibble-wide ( 4-bit) ports -PC Upper and PC Low. Each
connector is corresponding to one PPI chip with 24 DIO points.

8•Installation
2.2 Unpacking
Your card contains sensitive electronic components that can be easily
damaged by static electricity.
The card should be put on a grounded anti-static mat. The operator should
wear an anti-static wristband, grounded at the same point as the anti-static
mat.
Inspect the card module carton for obvious damage. Shipping and
handling may causedamage to your module. Be sure there is no shipping
and handling damage on the module before processing.
After opening the card module carton, extract the system module and place
it only on a grounded anti-static surface with components side up.
Again inspect the module for damages. Press down on all the socketed
IC's to make sure that they are properly seated. Do this only with the
module place on a firm flat surface.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN DAMAGED.
You are now ready to install your 24H/48H/96H series product.

2.4 Hardware Installation
PCIconfiguration
The PCI cards are equipped with a plug and play PCI controller,
it can request base addresses and interruptsin accordance with the PCI
standard. The system BIOS will install the system resource based on the
PCI cards’ configuration registers and system parameters (which are set
by system BIOS). Interrupt assignment and memory usage (I/O port
locations) of the PCI cards can be assigned by system BIOS only. These
system resource assignments are done on a board-by-board basis. It is
not suggested to assign the system resource by any other methods.
PCI slot selection
The PCI card can be inserted to any PCI slot without any configuration for
system resource. Please note that the PCI system board and slot must
provide bus-mastering capability to operate this board properly.
PCI Installation Procedures
1. Turn off your computer
2. Turn off all accessories (printer, modem, monitor, etc.) connected to
your computer.
3. Remove the cover from your computer.
4. Set up jumpers on the PCI card.
5. Select a 32-bit PCI slot. PCI slotsare shorter than ISA or EISA slots, and
are usually white or ivory.
6. Before handling the PCI cards, discharge any static buildup on your
body by touching the metal case of the computer. Hold the edge and do
not touch the components.
7. Position the board into the PCI slot you selected.
8. Secure the card in place at the rear panel of the system.

12 •Installation
Once Windows 95/98/2000/XP has started, the Plug and Play function of
Windows system will find the new PCIDAQ cards. If this is the first
time you're installing a PCIDAQ card in your Windows system, you will be
prompted to input the device information source. Please refer to the
“Software Installation Guide” for the steps of installing the device.
