Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its prod-
ucts will be free from defects in materials and workmanship for two years
from the date of purchase.
This warranty does not apply to any products which have been repaired or
altered by persons other than repair personnel authorized by Advantech,
or which have been subject to misuse, abuse, accident or improper instal-
lation. Advantech assumes no liability under the terms of this warranty as
a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous test-
ing, most of our customers never need to use our repair service. If an
Advantech product is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you will
be billed according to the cost of replacement materials, service time and
freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, CPU speed, Advantech products used, other hardware
and software used, etc.) Note anything abnormal and list any
onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your man-
ual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
merchandize authorization) number from your dealer. This allows
us to process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for war-
ranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

Technical Support and Assistance
Step 1. Visit the Advantech web site at www.advantech.com/support
where you can find the latest information about the product.
Step 2. Contact your distributor, sales representative, or Advantech's
customer service center for technical support if you need addi-
tional assistance. Please have the following information ready
before you call:
- Product name and serial number
- Description of your peripheral attachments
- Description of your software (operating system, version, appli-
cation software, etc.)
- A complete description of the problem
- The exact wording of any error messages
Packing List
Before setting up the system, check that the items listed below are
included and in good condition. If any item does not accord with the
table, please contact your dealer immediately.
• 1x PCM-3718 series card
• 1x Companion CD-ROM (DLL driver included)
• 1x User Manual (this manual)
• 1 x Counter Cable (P/N:1700001437) (PCM-3718HO only)
Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the
products from damage.
1. To avoid electrical shock, always disconnect the power from your
PC chassis before you work on it. Don't touch any components on
the CPU card or other cards while the PC is on.
Disconnect power before making any configuration changes. The sudden
rush of power as you connect a jumper or install a card may damage sen-
sitive electronic components.

The automatic channel-scanning circuitry and the onboard SRAM let you
perform multiple channel A/D conversions with DMA and individual
channel gains.
These PC/104 modules are fully software compatible with the popular
PCL-818H and PCL-818HG. This puts rich software support and a wide
variety of external signal conditioning boards at your disposal.
The PCM-3718 Series is excellent for data acquisition, process control,
automatic testing and factory automation.

1.6 Software Support
The PCM-3718 Series comes with a powerful and easy-to-use software
driver. This driver makes application programming much easier, espe-
cially when you use sophisticated features like interrupt or DMA data
transfer.
For creating a high performance Human Machine Interface (HMI), you
may need other supporting software beside our included driver for the
PCM-3718 cards. Please consult your Advantech representative for
appropriate software packages. Some suggestions are listed below.
ADAQView
ADAQView is a Windows-based data acquisition, control, analysis and
presentation development software package. In addition to typical
Human Machine Interface (HMI) functions, ADAQView features a
Visual Basic programming environment, and it provides numerous graph-
ical control and display icons to assist you in developing HMIs.
ActiveDAQ
ActiveDAQ is a collection of add-on ActiveX controls which provides an
easy-to-use property sheet interface for configuring analog/digital input/
output, counter/frequency, high-speed data acquisition and controls. You
can use ActiveX control in Visual Basic, Delphi and Visual C++ develop-
ment environments for Windows 98/2000/XP.
LabVIEW Driver
The Advantech LabVIEW driver supports National Instruments Lab-
VIEW 7.1 and runs in Microsoft Windows 98/2000/XP.
