Introduction
The PCI-1750 offers 16 isolated digital input channels, 16 isolated
digital output channels, one isolated counter and one timer with PCI
bus interface. With isolation protection of 2500 VDC the PCI-1750 is
ideal for industrial applications where high-voltage protection is
required.
The card's 16 bits are divided into two 8-bit I/O ports. This makes the
PCI-1750 very easy to program. This card also offers dual interrupt
handling capability, providing the user more flexibility in using the
counter, timer, digital inputs or a combination to generate interrupts to
the PC. A user can easily configure the interrupts through software.
The PCI-1750 uses a PCI controller to interface the card to the PCI
bus. The controller fully implements the PCI bus specification Rev
2.1. All bus relative configurations, such as base addresses and
interrupt assignments, are automatically controlled by software. No
jumpers or DIP switches are required for user configuration .
Numbering Convention
All numbers given in this manual are in decimal format unless
specifically noted otherwise. In particular, where a register address is
given as (Base + 32), the decimal number "32" should be added to the
base value.
Features
• 16 isolated digital input and 16 isolated digital output channels.
• High voltage isolation on all channels (2500 VDC )
• High sink current on isolated output channels (200 mA/Channel).
• D-type 37-pin female connector.
• Supports dry contact or 5 to 48 VDC isolated input.

Initial Inspection
Before starting to install the PCI-1750, make sure there is no visible
damage on the card. We carefully inspected the card both mechani-
cally and electrically before shipment. It should be free of marks and
in perfect order on receipt.
As you unpack the PCI-1750, check it for signs of shipping damage
(damaged box, scratches, dents, etc.) If it is damaged or fails to meet
specification, notify our service department or your local sales
representative immediately. Also, call the carrier immediately and
retain the shipping carton and packing materials for inspection by the
carrier. We will then make arrangements to repair or replace the unit.
Unpacking
The PCI-1750 contains components that are sensitive and vulnerable
to static electricity. Discharge any static electricity on your body to
ground by touching the back of the system unit (grounded metal)
before you touch the board.
Remove the PCI-1750 card from its protective packaging by grasping
the rear panel. Handle the card only by its edges to avoid static
discharge which could damage its integrated circuits. Keep the
antistatic package. Whenever you remove the card from the PC,
please store the card in this package for its protection.
You should also avoid contact with materials that hold static electrici-
ty such as plastic, vinyl and styrofoam.
Check the product contents inside the packing. There should be one
card, one CD-ROM, and this manual. Make sure nothing is missing.

Location of Connectors
Figure 2.1 shows the names and locations of connectors on the board.
The PCI-1750 is a plug and play device. The PCI BIOS assigns the
system resources automatically at system start-up. All functions can
be set by software. No jumpers or switches are used on this card.
