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

2.1 Initial Inspection
Inside the shipping container, you should find this operating
manual and the PCL-812PG card. The PCL-812PG is carefully
inspected and tested (mechanically and physically) prior to
shipping. It should be free of marks and scratches and in perfect
working order upon delivery.
When unpacking, check the unit for signs of shipping damage
(damaged box, scratches, dents, etc.). If there is any damage to
the unit or it fails to meet specifications, notify our service
departmet or your local sales representative immediately. In
addition, report the damage to the carrier. Retain the shipping
carton and packing material for inspection by the carrier. We
will then make arrangements to repair or replace the unit.
Remove the PCL-812PG interface card from its protective
packaging by grasping the rear metal panel. Keep the anti-
vibration packing. Whenever you remove the card from the PC
expansion slot, store the card in the protective package.
Discharge any static electricity by touching the back of the
system unit before you handle the board. You should avoid
contact with materials that create static electricity such as plastic,
vinyl and styrofoam. The board should be handled on by its
edges to avoid static electricity discharge which could damage
the integrated circuits on the PCL-812PG.
2.2 Jumper Settings
The PCL-812PG is designed for ease of use. There is one DIP
switch and nine jumpers on the PCL-812PG card and the
functions of the switch and the jumpers are discussed in this
section. You may want to refer to Fig. 2.1 for the physical
location 5 of the switch and the jumpers.

2.2.1 Base Address Selection
Switch name: SW1
Most PC peripheral devices and interface cards are controlled
through the input/output (I/O) ports. These ports are addressed
using the I/O port address space. Appendix A provides a PC I/O
port address map to help you locate appropriate addresses for
different devices.
The I/O port base address for the PCL-812PG is selectable via an
8-position DIP switch. The PCL-812PG requires 16 consecutive
address locations in I/O space. Valid addresses are from hex 200
to hex 3F0; however, you might have used some of these
addresses for other devices. Your PCL-812PG base address
switch setting is set to hex 220 in the factory. If you need to
adjust it to some other address range, the switch settings for
various base addresses are illustrated as below:
Note:
ON = 0, OFF = 1
A4...A9 correspond to PC bus address lines
* denotes factory setting
2.2.2 Wait State Selection
Some high speed PCs may require wait states to be added to the
bus I/O to achieve stable data transfer. The PCL-812PG can be
configured with 0, 2, 4 or 6 wait state delay for each transfer of
data. The length of the wait state can be selected with the
positions 7 and 8 on SW1, as shown below:
2.2.3 DMA Channel Selection
Jumper name: JP6, JP7
The PCL-812PG provides DMA data transfer capability. The
selection of DMA level 1 or level 3 is controlled by the jumpers.

the unit is facing you.
Remove the system unit cover (refer to your computer's
user's manual, if necessary)
Locate the expansion slots at the rear of the unit and choose
any unused slot.
Remove the screw that secures the expansion slot cover to the
system unit (save the screw to secure the interface card
retaining bracket).
Carefully grasp the upper edge of the PCL-812PG card.
Align the hole in the retaining bracket with the hole on top of
the expansion slot, and align the gold-striped edge connector
with the expansion slot socket. Press the board firmly into
the socket.
Replace the screw in the expansion slot retaing bracket.

The reference voltages of both D/A CH1 and CH2 are external:
The reference of D/A CH1 is internal and that of CH2 is external:
2.2.8 D/A Internal Reference Selection (JP8)
The internal reference voltage can be -5V or -10V. It is selected
by JP8. The reference voltage is -10V and the D/A output range
is 0 to +10V:
The reference voltage is -5V and the D/A output range is 0 to
+5V:
The internal reference is used only when the jumper JP3 or JP4 is
set to INT.
2.2.9 A/D Maximum Input Voltage Selection (JP9)
The A/D converter range can be +/- 5V or +/- 10V at it is
selected by jumper JP9. If JP9 is set in the +/- 5V range, the
analog input ranges of PCL-812PG are +/- 5V, +/- 2.5 V, +/-
1.25V, +/- 0.625V and +/- 0.3125V. If JP9 is set to the +/- 10V
range, the analog input ranges are then +/- 10V, +/- 5V, +/- 2.5V,
+/- 1.25V and +/- 0.625V. The default setting of JP9 is the +/-
5V range. The user can set JP9 to +/- 10V to double the input
range.
Some PC power supplies offer the bias voltage Vcc + with a
voltage less than +12V, e.g. +11.2V. In this case, the output
voltage swing range of the programmable amplifier cannot reach
+10V and the A/D converter CANNOT make correct
measurement if JP9 is set to +/- 10V range.
A/D converter maximum input range is +/- 10V:
2.3 Connector Pin Assignment
The PCL-812PG is equipped with two 20-pin insulation
displacement (mass termination) connectors, accessible from the
rear plate, and three other 20-pin insulation displacement
connectors on-board. All these connectors can be connected to
the same type of flat cables, or connected to 37-pin D-type
