1.1 Introduction
The PCL-812PG is a high performance, high speed, multi-function
data acquisition card for IBM PC/XT/AT and compatible
computers. The high-end specifications fo this full-sized card, and
complete software support from third-party vendors makes it ideal
for a wide range of applications in industrial and laboratory
environments. These applications include data acquisition, process
control, automatic testing and factory automation.
1.2 Key Features
• 16 single-ended analog input channels
• An industrial standard 12-bit successive approximation converter
(HADC574Z) to convert analog inputs. The maximum A/D
sampling rate is 30 KHz in DMA mode.
• Software programmable analog input ranges.
• Bipolar: +/- 5V, +/- 2.5 V, +/- 1.25V +/- 0.625 V +/- 0.3125 V
• Three A/D trigger modes:
• Software trigger
• Programmable pacer trigger
• External pulse trigger
• The ability to transfer A/D converted data by program control,
interrupt handler routine or DMA transfer.
• An Intel 8253-5 Programmable Timer/Counter provides pacer
output (trigger pulse) at the rate of 0.5 MHz to 35 minutes/pulse.
The timer increment is 2 MHz. One 16-bit counter channel is
reserved for user configuration applications.
• Two 12-bit monolithic multiplying D/A output channels. An
output range from 0 to +5V or 0 to +10V can be created by using
the on-board -5V or -10V reference. This precision reference is
derived from the A/D converter reference. External AC or DC
references can also be used to generate other D/A output ranges.

• 16 TTL/DTL compatible digital inputs, and 16 digital output
channels.
1.3 Expansion Capabilities
To complement the powerful features of the PCL-812PG, the
versatility of the card can be enhanced by using the following
optional daughter boards:
PCLD-789 Amplifier/Multiplier Board
This powerful front end analog input signal conditioning card can
multiplex 16 differential inputs to one A/D input channel. A high
grade instrumentation amplifier provides switch selectible gains of
0.5, 1, 2, 10, 50, 100, 200, 1000 or any user-definable gain.
PCLD-787 Eight Channel Simultaneous Sample and Hold
Front-End Board
The board allows up to eight analog inputs to be acquired
simultaneously with less than 30 ns of channel-to-channel sample
time uncertainty.
PCLD-786 AC/DC Power SSR and Relay Driver Board
This board provides 8 channels of photo-couple isolated solid-state
relay modules, plus an additonal 8 external relay driver outputs.
PCLD-785/885 Relay Output Board
This board provides 16 SPDT relays driven by the 16-bit digital
output channels of the PCL-812PG.
PCLD-782 Isolated D/I Board
This 16-channel opto-isolated digital input board provides an easy
way to input digital signals to the PCL-812PG.
PCLD-780 Wiring Terminal
Wiring terminal board for easy analog and/or digital I/O
connections
PCLD-779 Eight Channel Isolated Multiplexer and
Amplifier Board
Offers multi-channel temperature measurements when connected

PCLD-770/7701/7702 Signal Conditioning Modules
PCLD-770 Signal Conditioning Module Carrier Board.
With the PCLD-770 board, you can configure your requirements
with a signal conditioning module such as the PCLD-7701 or
PCLD-7702.
PCLD-7701 Isolated Amplifier
PCLD-7702 Amplifier with I/V Source
PCLD-5B16 Module Carrier Board
This module carrier board is equipped with 16 channels of 5B
series input and/or output modules which provide a complete
solution for signal conditioning applications.
1.4 Software Support
The PCL-812PG also provides powerful and easy to use software
driver functions which can be accessed by referring a user-defined
parameter table. These driver functions simplify programming,
especially when you want to use some of the sophisticated features
available with the PCL-812PG, for example, interrupt or DMA
data transfer.
To provide PCL-812PG users with more application support, a
variety of excellent third-party application software packages have
been integrated with the PCL-812PG. At present, the PCL-812PG
is supported by the following software:
PC-LabsDAS
Turnkey, menu-driven, general purpose data acquisition package
from Advantech
Labtech Notebook, PC-Scope, PC-Streamer, SNAPSHOT,
etc.
A complete software product catalog is available free from your
local PC-LabCard representative.
