PCI-1737U/PCI-1739U User Manual 2
Chapter 1 General Information
The PCI-1737U/PCI-1739U is a 24/48-bit DI/O card with PCI bus. It pro-
vides you with 24/48 bits of parallel digital input/output. It emulates
mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driv-
ing capability than the 8255. The I/O bits are divided into three 8-bit I/O
ports: A0, B0, and C0.( Six for PCI-1739U, A0, A1, B0, B1, C0, C1) You
can configure each port as either input or output via software.
The interrupt handling capability provides users the flexibility to generate
interrupt to a PC. One pin in the connector can output a digital signal
simultaneously with the card's generating an interrupt. (Two pin for PCI-
1739U)
The other features give the PCI-1737U/PCI-1739U practical advantages
in an industrial setting. When the system is hot reset or power on, the I/O
port settings and output values of PCI-1737U/PCI-1739U will be deter-
mined by switch.
1.1 Features
• Function Compatible with PCL-724/731 (24/48 TTL digital I/O lines)
• Emulates mode 0 of 8255 PPI
• Buffered circuits provide higher driving capability
• Output status readback
• Programmable interrupt handling
• Pin compatible with Opto-22 I/O module racks
• PCI universal card (both 3.3V and 5V signaling)

1.4 Software Overview
Advantech offers a rich set of DLL drivers, third-party driver support and
application software to help fully exploit the functions of your PCI-
1737U/PCI-1739U card:
• Device Drivers (on the companion CD-ROM)
• LabVIEW driver
• Advantech ActiveDAQ
• Advantech ADAQView
Programming choices for DA&C cards
You may use Advantech application software such as Advantech Device
Drivers. On the other hand, advanced users can use register-level pro-
gramming, although this is not recommended due to its laborious and
time-consuming nature.
Device Drivers
Advantech Device Driver software is included on the companion
CDROM at no extra charge. It also comes with all Advantech DA&C
cards. Advantech’s Device Drivers features a complete I/O function
library to help boost your application performance. Advantech Device
Drivers for Windows 2000/XP works seamlessly with development tools
such as Visual C++, Visual Basic, Borland C++ Builder and Borland Del-
phi.
Register-level Programming
Register-level programming is available for experienced programmers
who find it necessary to write code directly at the level of the device reg-
ister. Since register-level programming requires much effort and time, we
recommend that you use the Advantech Device Drivers instead. How-
ever, if register-level programming is indispensable, you should refer to
the relevant information in Chapter 4, Register Structure and Format, or
to the example codes included on the companion CD-ROM.

ous APIs that support many development tools, such as Visual C++,
Visual Basic, Delphi and C++ Builder.
1.5.3 Troubleshooting Device Drivers Error
Driver functions will return a status code when they are called to perform
a certain task for the application. When a function returns a code that is
not zero, it means the function has failed to perform its designated func-
tion. To troubleshoot the Device Drivers error, you can pass the error
code to DRV_GetErrorMessage function to return the error message.
Alternatively, you can refer to the Device Drivers Error Codes Appendix
in the Device Drivers Manual for a detailed listing of Error Codes, Error

PCLD-782B 24-channel Opto-isolated Digital Input Boards
The PCLD-782B digital input daughterboards feature high-voltage (1500
V DC ) optical isolation on all inputs. The PCLD-782B provides either 16
or 24 channels, depending on the connector you use. The PCLD-782B’s
20-pin connector lets you access 16 channels, similar to the PCLD-782.
The PCLD-782B also provides a 50-pin Opto-22 connector with access to
24 channels. Both cards have on-board screw terminals for easy input
wiring. Opticallyisolated signal conditioning provides isolation between
separate channels, as well as between each input channel and the PC. This
isolation prevents floating potential and ground loop problems while pro-
tecting the input lines from potentially damaging fault conditions. A red
LED on each input channel indicates its status. If the input signal is high,
the LED is on. You can configure each channel to work in either isolated
or non-isolated mode. A variable resistor adjusts the threshold level for
all 24 isolated input channels simultaneously.

pin flat cable connector and an additional 50-pin Opto-22 connector (for
PCLD-785B only) compatible with the digital outputs of most I/O Cards.
The number of output channels available on the PCLD-785B depends on
the connector you use. The I/O card’s 50-pin connector accesses all 24
channels, while its 20-pin connector has access to 16 channels. The
PCLD-785B automatically selects the correct control logic for the con-
nector in use.

ignored.
Before removing the card from the antistatic plastic bag, you should take
the following precautions to ward off possible ESD damage:
Touch the metal part of your computer chassis with your hand to dis-
charge the static electricity accumulated on your body. Alternatively, one
can also use a grounding strap.
Touch the anti-static bag to a metal part of your computer chassis before
opening the bag.
Take hold of the card only by the metal bracket when removing it out of
the bag.
After taking out the card, you should first:
Inspect the card for any possible signs of external damage (loose or dam-
aged components, etc.). If the card is visibly damaged, please notify our
service department or our local sales representative immediately. Do not
install a damaged card into your system.
Also, pay extra caution to the following aspects during installation:
Avoid physical contact with materials that could hold static electricity
such as plastic, vinyl and Styrofoam.
