ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
!
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
!
Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps
to discharge any static electricity on your body.
!
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

iii
Unpacking
The AX5320P is packed in an anti-static bag. The PCI Bus
board has components that are easily damaged by static
electricity. Do not remove the anti-static wrapping until proper
precautions have been taken. Safety instructions in front of this
User's Manual describe anti-static precautions and procedures.
After unpacking the PCI Bus board, place it on a raised surface
and carefully inspect the board for any damage that might have
occurred during shipment. Ground the board and exercise
extreme care to prevent damage to the board from static
electricity.
Integrated circuits will sometimes come out of their sockets
during shipment. Examine all integrated circuits, to ensure that
they are firmly seated. The AX5320P PCI Bus interface analog
output board package includes the following:
! AX5320P Board
! AX5003 Extension Board
! Flat cable 40p 45cm x 1
! AS59099 DAC Driver CD
! Ax5320P user's manual
! Warranty card
Make sure that all of the items listed above are present.
What To Do If There Is A Problem
If there are damaged or missing parts, contact your supplier
and/or dealer immediately. Do not attempt to apply power to the
board if there is damage to any of its components.

Introduction
1.1
General Description
The AX5320P is a PCI card providing 6 channels analog output
and 8 digital inputs, and/or 8 digital outputs. The board
interface allows its plugging into any PCI slot of an IBM™
PC/AT or compatible computer with PCI bus.
The AX5320P features 6 channels of voltage output or current
sink, each channel is individually user selectable to any of the
following ranges: 0 to 5V, 0 to 10V, -5V to +5V, -10V to +10V, 0
to 20 mA or 4 to 20 mA current loop. There is one 12-bit D/A
converter per channel for maximum 33KHz throughput. Typical
applications for AX5320P include ON/OFF control, direct
control valve positioning, waveform generation and utilizing a
variable voltage output. The board can also be used for analog
control in process or laboratory application where material
transfer rates, fluid flow, power consumption, motor speed,
temperature levels, etc., are to be controlled. Optional AX851
universal terminal panel is available to help facilitate external
connections.

Code Format
There are three kinks of reference voltage input ( -5V, -10V and
external ) can be selected by the jumper JP2, JP4, JP6, JP8,
JP10, JP12. W hen the voltage reference (Vref) is selected, this
channel’s D/A voltage output range is from 0V to |Vref| for
unipolar (UNI), -|Vref| to |Vref| for biplar (BIP). The reference
signal can be DC or AC voltage. In this way, the D/A becomes a
programmable atenuator. The equation for calculating output is:
DAV = |Vref| *[code/4096]
W here code is the data written to the D/A register, the range is
between 0 to 4095.

Hardware Installation
The AX5320P board is shipped with protective electrostatic
cover. W hen unpacking, touch the board's electrostatically
shielded packing with the metal frame of your computer to
discharge the accumulated static electricity prior to touching
the board.
The following section summarizes the procedures when
installing the AX5320P:
WARNING:
Turn OFF the PC and all accessories
connected to the PC whenever installing or
removing any peripheral board including the
AX5425(0) series board.
2.5.1 Board Installation
The following lists the instructions to follow when installing the
AX5320P card.
1. Turn OFF the PC and all accessories power.
2. Unplug all power cords and entire cables from the
rear of the PC.
3. Remove the PC's cover (see your PC Operation
Guide if you are not skillful about it).
4. Find an unused expansion slot. Remove the blank
expansion slot cover and save the screw for affixing
retaining bracket.
5. Grab the upper edge of the AX5320P board. Align
the AX5320P board's retaining bracket with the
expansion slot rear panel, and straighten the
board's gold finger with the expansion slot. Gently
push the board into slot.
6. Restore the screw to the expansion slot-retaining
bracket.
7. Replace the PC's cover and connect the cables
you detached in step2.
8. Turn ON the power of the PC and other peripheral
device.

I/O Address Mapping
The AX5320P use some non-consecutive addresses in I/O
space. All registers are 8 bits wide. The base address (or
starting address) is determined during the installation by CPU
auto setting. This chapter describes each register's format and
functions. Each register can be accessed easily by using direct
I/O instructions of whatever application languages available
(Assembly, Basic, Pascal, C, etc.). Don't operate any other
I/O( NOT LISTED) , or else it happens errors.

3.2.2 Group_1 registers
NOTE:
When users program the registers in Group_1, they
must check if the I/O port Base address + 2 has an
output value 0x03(or 0x0f), and the I/O port Base
address + 3 has an output value 0x01 to enable the
functions in Group_1.

Calibration
4.1
D/A Calibration
D/A adjustment is executed for AX5320P D/A calibration.The
D/A output voltage can be measured by a DVM or directly to
other AXIOMTEK’s A/D cards.
Step 1:
Connect TP1(+) and AGND(-) to
multimeter(recmmend HP34401A). Trim VR1 to
measure the voltage equal +2.5000V.
Step 2:
Connect TP2(+) and AGND(-), trim VR3 to
measure the voltage equal –10.0000V.
Step 3:
Connect TP3(+) and AGND(-), trim VR2 to
measure the voltage equal –5.0000V.
Step 4:
Run the calibration program cal5320p.exe
and conform it.
