PCI-1750/PCI-1750SO User Manual 2
1.1 Introduction
The PCI-1750/PCI-1750SO offers 16 isolated digital input channels, 16 isolated digi-
tal output channels, one isolated counter and one timer with PCI bus interface. With
isolation protection of 2500 VDC the PCI-1750/PCI-1750SO 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/PCI-
1750SO 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 combi-
nation to generate interrupts to the PC. A user can easily configure the interrupts
through software.
The PCI-1750/PCI-1750SO 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.
1.2 Features
16 isolated digital input and 16 isolated digital output channels.
High voltage isolation on all channels (2500 VDC)
Driving current capability on isolated output channels (200 mA/Channel).
D-type 37-pin female connector.
Supports dry contact or 5 to 50 VDC isolated input.
Dual interrupt handling capability
Timer / Counter interrupt capability generates watchdog timer interrupts
1.3 Applications
Digital I/O control.
Industrial ON/OFF control.
Industrial and lab automation.
Switch status sensing
BCD interfacing.

2.1 Initial inspection
Before starting to install the PCI-1750/PCI-1750SO, make sure there is no visible
damage on the card. We carefully inspected the card both mechanically and electri-
cally before shipment. It should be free of marks and in perfect order on receipt.
As you unpack the PCI-1750/PCI-1750SO, 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.
2.2 Unpacking
The PCI-1750/PCI-1750SO 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/PCI-1750SO 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 electricity such as plas-
tic, 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.

2.3 Location of Connectors
Figure 2.1 shows the names and locations of connectors on the board.
The PCI-1750/PCI-1750SO is a plug and play device. The PCI BIOS assigns the sys-
tem resources automatically at system start-up. All functions can be set by software.
One jumper and one switch are used on this card. .
Figure 2.1 Location of Jumper and DIP switch
The default configuration after the power is switched on, and the hardware has been
reset is to set all the isolated output channels to “open” (the current of the load can’t
be sinked) so that users do not have worry about damaging external devices during
system startup or reset.
When the system is hot reset, then the status of the isolated digital output channels
are selected by jumper JP2. Table 2-1 shows the configuration of jumper JP2.

Board ID (SW1)
The PCI-1750/PCI-1750SO has a built-in DIP switch (SW1), which is used to define
each cards board ID. When there are multiple cards on the same chassis, this board
ID switch is useful for identifying each cards device number.
After setting each PCI-1750/PCI-1750SO, you can identify each card in system with
different device numbers. The default value of board ID is 0 and if you need to adjust
it to other value, please set the SW1 by referring to Table 2.2.
