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.

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.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may
damage sensitive electronic components.

0.1% input range accuracy, or 4~20 mA inputs. Reliable and rugged
enough for industrial applications, yet inexpensive enough for home
projects, USB-4718 is the perfect way to add measurement and control
capability to any USB capable computer. The USB-4718 is fully USB
plug and play and easy to use. It obtains all required power from the USB
port, so no external power connection is ever required.

• Software configurable for thermocouple, low level voltage or current
inputs.
• Wiring burned-out detectable function (Thermo mode)
• 2,500 Vdc isolation
• Watchdog Timer
• Supports 0~20 & 4~20mA current inputs.
• Bus-powered
• Device status LED indicator
• Removable on-module wiring terminal
• USB 2.0 Support
• Hot swappable
1.2 Applications

1.3 Installation Guide
Before you install your USB-4718 module, please make sure you have
the following necessary components:
• USB-4718 DAS Module
• USB-4718 User Manual
• Shielded USB 2.0 cable (1.8 m)
• Driver software Advantech DLL drivers (included in the companion
CD-ROM)
• Personal computer or workstation with a USB port (running Windows
2000, or XP)
Some application software is also available for enhanced operation. USB-
4718 works with ActiveDAQ, ActiveDAQ Pro, and other third-party
software packages.
After you have the necessary components and maybe some accessories
for enhanced operation of your USB DAS module, you can then begin the
installation procedure. Figure 1.1 on the next page provides a concise
flow chart to give a broad picture of the software and hardware installa-
tion procedures.
