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.

MIC-3758DIO User Manual 2

Chapter 1 General Information

1.1 Introduction

Thank you for buying the Advantech MIC-3758DIO DAS card. The

Advantech MIC-3758DIO card is a powerful data acquisition (DAS) card

for the CompactPCI bus. It features a unique circuit design and complete

functions for data acquisition and control. The MIC-3758DIO card pro-

vide specific functions for different user requirements:

The following sections of this chapter will provide further information

about features of the DAS cards.

1.2 Features

The Advantech MIC-3758DIO DAS card provides users with the most

requested measurement and control functions as seen below:

Digital Output

• 64 isolated digital output channels

• High-voltage isolation on output channels (2,500 VDC )

• Wide output range (5 ~ 40 VDC )

• High-sink current for isolated output channels (90 mA max./Channel)

• Current protect for each port

• Output status read-back

• Digital output value retained after hot system reset

• Programmable Power-Up States

• Watchdog Timer

3 Chapter1

Digital Input

• 64 isolated digital input channels

• High-voltage isolation for input channels (2,500 VDC )

• Wide input range (5 ~ 25 VDC )

• High ESD protection (2,000 VDC )

• Digital Filter function

• Interrupt handling capability

• Robust Isolation

• BoardID switch

MIC-3758DIO features robust isolation protection for applications in

industrial, lab and machinery automation. MIC-3758DIO can durably

withstand a voltage up to 2,500 VDC, preventing your host system from

any incidental harms. MIC-3758DIO, if connected to an external input

source with surge-protection, can offer up to a maximum of 2,000 VDC

ESD (Electrostatic Discharge) protections for input channels.

1.2.1 Wide Input/Output Range

MIC-3758DIO has a wide range of input voltage from 5 to 25 VDC, and

it is suitable for most industrial applications with 12 VDC and 24 VDC

input voltage. MIC-3758DIO also features a wide output voltage range

from 5 to 40 VDC, suitable for most industrial applications with 12 VDC

/ 24 VDC output voltage. In the mean time, we are also ready to serve

your special needs for specific input/output voltage ranges.

1.2.2 BoardID Switch

MIC-3758DIO has a built-in DIP switch that helps define each card’s ID

when multiple cards have been installed on the same PC chassis. The

BoardID setting function is very useful when you build your system with

multiple MIC-3758DIO cards. With correct BoardID settings, you can

easily identify and access each card during hardware configuration and

software programming.

MIC-3758DIO User Manual 4

1.2.3 Programmable Power-Up State Function

User-configurable power-up states are useful for ensuring that MIC-

3758DIO powers up in a known state. Power-up states are programmed in

the EEPROM through the driver.

1.2.4 Watchdog Timer Function

The watchdog timer is a software configurable feature used to set critical

outputs to safe states in the event of a software failure. If there is loss of

communication between the application and MIC-3758DIO, if the watch-

dog timer is enabled and MIC-3758DIO does not receive a watchdog

clear software command within the interval time specified for the watch-

dog timer, the outputs go to a user-defined safe state and remain in that

state until the watchdog timer is disabled and new values are written by

the software. After the watchdog timer expires, MIC-3758DIO ignores

any writes until the watchdog timer is disabled. You can set the watchdog

timer timeout period through the WDT register to specify the amount of

time that must elapse before the watchdog timer expires. The counter on

the watchdog timer is configurable up to 232-1 x 100 ns (approximately

seven minutes) before it expires.

1.2.5 Reset Protection

If the system has undergone a hot reset (i.e. system power was not turned

off), MIC-3758DIO can either retain output values of each channel, or

return to its default configuration as power up status, depending on its on-

board jumper setting. This function protects the system from wrong oper-

ations during unexpected system resets.
