CHAPTER

1. Introduction
Thank you for buying the Advantech MIC-3716 CompactPCI (cPCI)
card. The Advantech MIC-3716 is a powerful data acquisition (DAS)
card which complies with PICMG 2.0 R2.1 CompactPCI
specifications. It features a unique circuit design and complete
functions for data acquisition and control, including A/D conversion,
D/A conversion, digital input, digital output, and counter/timer.
MIC-3716 provides specific functions for different user requirements.
The following sections of this chapter will provide further information
about features of the multifunction cards, a quick starting guide for
installation, as well as some brief information on software and
accessories for the MIC-3716 card.

1.1 Product Description
The Advantech MIC-3716 provides users with the most requested
measurement and control functions as below:
wCompactPCI bus specification 2.1 compliant
wPCI-bus mastering for data transfer
w16-channel Single-Ended or 8 differential analog input
w16-bit A/D conversion with up to 250 KS/s sampling rate
wProgrammable gain for each input channel
w1K on board samples FIFO buffer
w2-channel analog output
w16-channel digital input
w16-channel digital output
wProgrammable counter/timer
wAutomatic channel/gain scanning
wI/O address automatically assigned by PCI plug-and-play
wBoard ID
The Advantech MIC-3716 offers the following main features:
Plug-and-Play Function
The Advantech MIC-3716 is a Plug-and-Play device that fully
complies with the PCI Specification Rev 2.2. During card installation,
all bus-related configurations such as base I/O address and interrupts
are conveniently taken care of by the Plug-and-Play function. You
have virtually no need to set any jumpers or DIP switches.

4
Flexible Input Type and Range Settings
The MIC-3716 features an automatic channel/gain scanning circuit.
This circuit design controls multiplexer switching during sampling.
Users can set different gain values for each channel according to their
needs for the corresponding range of input voltage. The gain value
settings thus selected is stored in the SRAM. This flexible design
enables multi-channel and high-speed sampling for high-performance
data acquisition.
On-board FIFO (First-In-First-Out) Memory
The MIC-3716 provides anonboard FIFO memory buffer that can
store 1K samples. Users can either enable or disable the interrupt
request feature of the FIFO buffer. While the interrupt request for
FIFO is enabled, users are allowed to specify whether an interrupt
request will be sent with each sampling action or only when the FIFO
buffer is half saturated. This useful feature enables a continuous
high-speed data transfer with a more predictable performance on
operating systems.
16 Digital Inputs and 16 Digital Outputs
The MIC-3716 provides 16 digital input channels and 16 digital
output channels. This leaves you with great flexibility to design and
customize your applications according to your specific needs.
On-board Programmable Counter
The MIC-3716 is equipped with a programmable counter, which can

5
serve as a pacer trigger for A/D conversions. The counter chip is an
82C54 or its equivalent, which incorporates three 16-bit counters on a
10 MHz clock. One of the three counters is used as an event counter
for input channels or pulse generation. The other two are cascaded
into a 32-bit timer for pacer triggering.
Short Circuit Protection
The MIC-3716 is equipped with short circuit protection device
(polyswitch) on the +12VDC/+5VDC power supply pins.If any of the
power supply pins are shorted to ground (i.e. short circuit occurs), the
protection device will shut off the current output automatically. After
the short circuit has been released for about two minutes, the power
supply pins will return tooutput current.
Board ID
The MIC-3716 has a built-in DIP switch that helps define each card’s
ID when multiple cards have been installed on the same CompactPCI
system. The board ID function is very useful when users build their
system with multiple MIC-3716 cards. With the correct Board ID
settings, you can easily identify and access each card during hardware
configuration and software programming.
Note:
1. Pace trigger determines how fast A/D conversion will be done in pacer
trigger mode.
2. For detailed specifications of the MIC-3716, please refer to Appendix A,
Specifications.

1.2 What You Need to Get Started
Before you install your MIC-3716 card, please make sure you have
the following necessary components:
wMIC-3716 Multifunction card
wMIC-3716 User’s Manual
wDriver software Advantech DLL drivers (included in the
companion CD-ROM)
wWiring cable PCL-10168
wWiring board PCLD-8710, ADAM-3968
wComputer Personal computer or workstation with a
CompactPCI-bus slot (running Windows
95/98/NT/2000/XP)
Some other optional components are also available for enhanced
operation:
wApplication software ActiveDAQ, GeniDAQ or other third-party
software packages
After you get the necessary components and maybe some of the
accessories for enhanced operation of your Multifunction card, you
can begin the Installation procedure. Fig.1-1on the next page
provides a concise flow chart to give you a broad picture of the
software and hardware installation procedures:

1.3 Software Programming Choices
Advantech offers a rich set of DLL drivers, third-party driver support
and application software to help fully exploit the functions of your
MIC-3716 card:
wDLL driver (on the companion CD-ROM)
wLabVIEW driver
wAdvantech ActiveDAQ
wAdvantech GeniDAQ
For more information on software, please refer to Chapter 4, Software
Programming Overview.
Users who intend to program directly at the registers of the
multifunction card can have register-level programming as an option.
Since register-level programming is often difficult and laborious, it is
usually recommended only for experienced programmers. For more
information, please refer to Appendix C, Register Structure and
Format.

1.4 Optional Accessories
Advantech offers a complete set of accessory products to support the
MIC-3716 cards. These accessories include:
Wiring Cable
nPCL-10168 The PCL-10168 shielded cable is specially
designed for MIC-3716 cards to provide high
resistance to noise. To achieve a better signal
quality, the signal wires are twisted in such a way
as to form a “twisted-pair cable”, reducing
cross-talk and noise from other signal sources.
Furthermore, its analog and digital lines are
separately sheathed and shielded to neutralize
EMI/EMC problems.
Wiring Boards
nADAM-3968 The ADAM-3968 is a 68-pin SCSI wiring
terminal module for DIN-rail mounting. This
terminal module can be readily connected to
Advantech PC-LabCard products and allow easy
yet reliable access to individual pin connections
for the MIC-3716 card.
nPCLD-8710 The PCLD-8710 is a DIN-rail mounting
screw-terminal board to be used with any of the
PC-LabCard products which have 68-pin SCSI

10
connectors. The PCLD-8710 features the
following functions:
wTwo additional 20-pin flat-cable connectors
for digital input and output
wReserved space on the board to meet future
needs for signal-conditioning circuits (e.g.
low-pass filter, voltage attenuator and current
shunt)
wIndustrial-grade screw-clamp terminal blocks
for heavy-duty and reliable connections.
