ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction
The DASP-52032 is a PCI-bus, 16 isolated D/I and 16 relay output
card. It supports not only optical isolation (2500VDC), but also
over-voltage protection (50VDC) to enhance the reliability of the
system. The DASP-52032 also supports two types of relay actuatorSPDT & SPST, making it suitable for controls and sensing
applications such as load switching, external switching detection, and
contact closure.
Easy to Troubleshoot Hardware Resource- PCI Scan
Utility
The PCI scan utility can scan all the DASP products within the system,
and can show users all system resources, such as serial numbers,
IRQ, and I/O addresses. This lets users clearly see through and
immediately know whether all DASPs are working normally,
decreasing the time of searching confirmation.

2.3 Jumper Setting
Each digital input channel of DASP-52032 can be configured to AC
type or DC type independently. Jumper 1 ~ Jumper 8 relates DI0~DI7,
and Jumper 9 ~ Jumper 16 relates DI8~DI15, as listed in the following
table. When the AC input type of a specific channel is configured, the
input path of the channel is automatically attached to an AC filter with
a time constant of 1.2ms (60Hz low pass).

2.5 Quick Setup and Test
To install a new DASP-52032 into an IBM PC compatible computer, at
first, power-off the PC and open its chassis, then plug the
DASP-52032 into a PCI slot of mother-board. The DASP-52032 is a
plug and play device for MS Windows, and the OS will detect your
DASP-52032 after you power on the PC. The detail of driver and
software installation is described in software manual of DASP-52032.
After the hardware and software installation, user can emulate and
test DASP-52032 step by step as follows.
To perform a complete test of DASP-52032, we can
route the input signals of DASP-52032 with a
specific input pattern for read-back. And the output
status of each channel can be observed directly
from the on-board led indicator of each channel, or
to estimate the mechanical movement of the SPDT
relay of each channel. And then, by following the
DASP-52032 test branch of the ToolWorkShop
which will fully test all the digital I/O channels of
the DASP-52032 as descried in the following
paragraphs.
Launch the ‘PCI Configuration Utility’ of
DASP-52032 to ensure that the resource of
DASP-52032 is properly dispatched by the OS.
Press the scan button in the toolbar of the ‘PCI
Configuration Utility’ to find the installed
DASP-52032, and then check the resource list.

3.2 Relay Output
The DASP-52032 provides 8 relay output. The low 8 bits (D0 - D7) of
the relay 0 ~ 7 outputs are stored in base address 0. For DASP-52032,
the high 8 bits (D8 – D15) of the relay 8 ~ 15 outputs are stored in
base address 0. A high bit turns the relay on while a low bit turns the
relay off. The 8 bits of relay output register are shown in the following.
