| Introduction |
The PCI bus
14 bit data acquisition card is a 32 bits PCI bus adapter with Plug and
Play (PnP) features, it is a programmable I/O interface for Pentium or
compatible computers. The PnP features let hardware configuration for
IRQ and I/O address is detected by BIOS automatically, you don’t need
set switch and jumper.
The PCI bus 14 bit data acquisition card is a high precision data
conversion/acquisition system. It contains 16 analog to digital
channels with unipolar or bipolar input, 2 digital to analog channels
with unipolar or bipolar output and 1 digital I/O channel with 16 bit
line. The on board 8254(71054) chip provides programmable interval
timer/counter functions to trig A/D conversion. The PCI bus 14 bit data
acquisition card also provides interrupt driven for convention A/D
input.

| UNPACKING INFORMATION |
|
Check that your
PCI bus 14 bit data acquisition package includes the following items:
|
|
PCI bus 14 bit data
acquisition adapter.
|
|
User manual. |
|
Software utilities. |
|
Warranty form. |
|
SYSTEM REQUIREMENTS
Before installing your PCI bus 14 bit data acquisition adapter, make
sure that:
|
The host computer is an
Pentium compatibles. |
|
The
seven jumpers' blocks are correctly configured to coincide with the
operating system you are using.
|
|
| HARDWARE
INSTALLATION |
| Your PCI bus 14 bit data acquisition adapter is
designed to be inserted in any available slot in your Pentium or
compatibles. In order to gain access to the expansion slots, follow the
steps listed below: |
|
1.
|
Turn off all power to your
computer and all peripheral devices before installing your 14 bit data
acquisition adapter. |
| 2. |
Remove the cover of the computer.
|
3.
|
Insert the
pre-configured 14 bit data acquisition adapter into any available slot.
Make sure the adapter is firmly seated in the chosen slot.
|
| 4. |
Replace the cover of the
computer.
|
|
|
| Note: |
| 1. |
You
must adjust the A/D full scalar reference voltage by screwing the VR
resistor. (see VR Full Scalar Adjustment).
|
| 2. |
You
must setup everything including the connection of the signal
input/output into the DB25 and J2 connectors before turning on the PC
power, otherwise it may damage the card.
