Introduction 1
1 Introduction
JYTEK'S PCIe-67432 for PCIe bus provides 32CH isolated DI and 32CH iso-
lated DO and robust 2,500V isolation protection, suitable for most
industrial applications.
All digital input channels are identical non-polar and opto-isolated. All
channels are isolated and suitable for collecting digital inputs in noisy
environments. Digital input channel 0 & 1 interrupt are supported.
Common input junction can be common ground or common power,
depending on the environment, such that digital input can be either cur-
rent source or current sink. When isolated digital output is ON, sink cur-
rent is through transistors, and when OFF, none is.
The extra connection is utilized for the flywheel diode, forming a cur-
rent-release closed loop, whereby transistors are protected from high
reverse voltage generated by the inductance load when output is
switched from ON to OFF.

1.7 DI/O Channels
Isolated Digital Input Channels
Isolated digital input has an open collector transistor structure with
voltage range 0V to 24V and input resistance of 2.4kΩ. Connection
between external signals and the PCIe-67432 is as shown in Fig A01.
Since input common junction can be common ground in the environ-
ment, digital input can be either a current source or a current sink.

Figure 1-3: Isolated Input Connection
Isolated Digital Output Channels
Common ground connection of the isolated digital output is as shown.
When isolated digital output is ON, sink current is through transistors,
and when OFF, none is. When the load is of an inductance nature, such
as a relay, coil or motor, the VDD pin must be connected to an external
power source. The extra connection is utilized for the flywheel diode to
form a current-release closed loop, whereby transistors are protected
from any high reverse voltage generated by the inductance load when
output is switched from ON to OFF.

2.1 Unpacking Checklist
Before unpacking, check the shipping carton for any damage. If the ship-
ping carton and/or contents are damaged, inform your dealer immedi-
ately. Retain the shipping carton and packing materials for inspection.
Obtain authorization from your dealer before returning any product to
JYTEK. Ensure that the following items are included in the package.
PCIe-67432 high-speed DI/O card
If any of the items is damaged or missing, contact your dealer immedi-
ately.
2.2 Installing the Card
Install the card driver before you install the card into your computer sys-
tem. See “Software Support” on page 3. for driver support information.
To install the card:
1. Turn off the system/chassis and disconnect the power plug
from the power source.
2. Remove the system/chassis cover.
3. Select the PCIE Express slot that you intend to use, then
remove the bracket opposite the slot, if any.
4. Align the card connectors (golden fingers) with the slot, then
press the card firmly until the card is completely seated on
the slot.
5. Secure the card to the chassis with a screw.
6. Replace the system/chassis cover.
7. Connect the power plug to a power source, then turn on the
system.
CAUTION:
The card must be protected from static discharge and physical shock.
Never remove any of the socketed parts except at a static-free work-
station. Use the anti-static bag shipped with the product to handle
the card. Wear a grounded wrist strap when servicing.

10 Getting Started
Configuration
All PCI/PCIE Express cards on your system are configured individually.
Because configuration is controlled by the system and the software, no
jumper setting is required for base address, DMA, and interrupt IRQ.
Configuration is subject to change with every boot of the system as new
PCI/PCIE Express® cards are added or removed.
Troubleshooting
If your system fails to boot or if you experience erratic operation with
your PCI/PCIE Express card in place, an interrupt conflict may have been
generated (such as when the BIOS Setup is incorrectly configured).
Refer to the system’s BIOS documentation for details.
