Introduction
The 12 bit data acquisition card is a high precision data
conversion/acquisition system for PC/XT, PC/AT, PC/386, Pentium or
compatibles. It contains 16 analog to digital channels with
unipolar or bipolar input and 4 digital I/O channels with 8 bit line
for each channel. The on board 8254 chip provides programmable interval
timer/counter functions to trig A/D conversion. The 12 bit data
acquisition card also provides interrupt driven for convention A/D
input. |
|
|
The features of the 12
bit data acquisition adapter are:
 |
Provides 16 A/D channels
and the resolution is 12 bits. |
|
Unipolar or bipolar
selectable. |
|
Input
voltage range from 0 to 10V or 0 to 20V for unipolar, and from -5V to
5V or -10V to 10V for bipolar. |
|
Provides 4 digital
input/digital output channels and the resolution is 8 bits. |
|
Provides three independent
16 bits counter to trig A/D conversion. |
|
I/O port address
selectable. |
|
ISA bus interrupt
programmable (IRQ3 to IRQ15). |
|
Gain control factor
selectable from 1 to 8. |

| System requirements |
|
Before installing your 12 bit
data acquisition adapter, make sure that:
|
|
The
host computer is an IBM PC/AT, PC/386, PC/486, and Pentium compatibles.
|
|
The
five jumpers' blocks are correctly configured to coincide with the
operating system you are using. |
|
| Hardware Installation |
|
Your 12 bit data acquisition adapter is
designed to be inserted in any available slot in your PC/AT, PC/386,
PC/486, Pentium or compatibles. In order to gain access to the
expansion slots, follow the steps listed below:
|
|
Turn
off all power to your computer and all peripheral devices before
installing your 12 bit data acquisition adapter.
|
|
Remove the cover of the
computer.
|
|
Insert
the pre-configured 12 bit data acquisition adapter into any available
slot. Make sure the adapter is firmly seated in the chosen slot. |
|
Replace the cover of the
computer. |
|
Note: |
1.
|
You
must adjust the A/D full scalar reference voltage by screwing the VR
resistor. (see R Full Scalar Adjustment). |
2.
|
You
must setup everything including the connection of the analog input into
the DB25 channel input before turning on the PC power, otherwise it may
damage the card |
