The following sections of this chapter will provide further information
about features of the DAS cards, a Quick Start for installation, together
with some brief information on software and accessories for the PCI-
1711/1731card.
1.1 Features
The Advantech PCI-1711/1731 provides users with the most requested
measurement and control functions as seen below:
q16-channel Single-Ended A/D Input
q12-bit A/D conversion with up to 100 kHz sampling rate
q16-channel Digital Input
q16-channel Digital Output
q2-channelD/A Output (onlyfor PCI-1711)
qProgrammableCounter/Timer
qAutomatic Channel/Gain Scanning
TheAdvantech PCI-1711/1731offers the followingmain features:
Plug-and-Play Function
The Advantech PCI-1711/1731 is a Plug-and-Play device, which fully
complieswith the PCISpecification Rev 2.1. 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.
Flexible Input Types and Range Settings
The PCI-1711/1731 features an automatic channel/gain scanning
circuit. This circuit design controls multiplexer switching during
sampling. Users can set different gain values for each channel

www.advantech.com
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 (up to 100 KS/s .)
On-boardFIFO(First-In-First-Out) Memory
The PCI-1711/1731 provides an on-board FIFO memory buffer, storing
up 1 to 1K A/D 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.
Optional D/A Output for Cost Savings
The PCI-1711 goes further with 2 analog output channels, while the
PCI-1731 doesn’t. It is for users to differentiate between the PCI-1711
and the PCI-1731 according to what they really need as the best
solution with no extra cost.
16 Digital Inputs and 16 Digital Outputs
The PCI-1711/1731 provides 16 digital input channels and 16 digital
output channels. Users are left with great flexibility to design and
customize their applications according to their specific needs.
On-board Programmable Counter
ThePCI-1711/1731isequipped with a programmable counter, which
can 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.
Note:
✎Pace trigger determines how fast A/D conversion will be done in pacer
trigger mode.
