1. Introduction
The PCI-822/826 Series cards provide 32/16-channel 12-bit (16-bit) Analog Input with a sampling rate
of up to 250 kSamples/second, and 2-channel 16-bit Analog Output with 32-channel programmable
Digital Input/Output.
1.1 Overview
The PCI-822/826 Series are high-performance multifunction cards that provide high-speed Analog
and Digital I/O functions. PCI-822/826 Series cards use a Universal PCI interface that supports both
the 3.3 V and the 5 V PCI bus. These cards feature a continuous, 250 kSamples/second, 12-bit
(16-bit) resolution A/D converter, an 8 k-Sample hardware FIFO, a 2-channel, 16-bit D/A converter,
and a 32-channel programmable Digital Input/Output and Digital Output readback. The PCI-822/826
LU provides either 32-channel single-ended or 16-channel differential Analog Input that is jumper
selectable, while the PCI-826LU is equipped with a high-speed PGA (Programmable Gain Amplifier)
featuring programmable gain controls (1, 2, 4 and 8).
PCI-822/826 Series cards contain an embedded Card ID switch and onboard pull-high/pull-low
resistors for the Digital Input, meaning that a unique ID number can be set for each card so that can
each card can be individually recognized when two or more PCI-822/826 Series cards are used in a
computer at the same time. The pull-high/pull-low resistors allow the status of the Digital Input to
be specified, meaning that when the Digital Input channels are disconnected, the status of the
Digital Input will remain as either high or low and will not be set to floating.
PCI-822/826 Series cards provide both a programmable software trigger and a pacer trigger, and
include an A/D channel scan function called MagicScan. The MagicScan controller eliminates the
majority of the effort required to acquire the A/D values, such as selecting the channel, setting the
Gain values and the settling time, triggering the ADC, and acquiring the data. Using the built-in
MagicScan and the interrupt features, these complex tasks are effectively offloaded from the CPU.
Even in channel scan mode, a different Gain code can be used for each channel, and the sampling
rate can still achieve a total of 250 kS/s, making the PCI-822/826 Series well-suited to the demands
of high-end applications.

2.5 Analog Input Signal Connections
PCI-822/826 Series cards can be used to measure either single-ended or differential type Analog
Input signals. Although certain signals can be measured using either mode, other signals, however,
can only be measured in one mode or the other. The most suitable mode for the measurement
must be determined beforehand, and is totally dependent on the prevailing measurement
conditions.
In general, there are four different methods that can be used for connecting Analog Input signals, as
shown below in Figures 2.5-1 to 2.5-5. The connection method illustrated in Figure 2.5-1 is more
suitable for grounding source Analog Input signals. The connection method depicted in Figure 2.5-3
is used to measure more channels than the method shown in Figure 2.5-1, but it is only suitable for
large Analog Input signals. The connection method shown in Figure 2.5-4 is suitable for
thermocouple input signals, while the connection method illustrated in Figure 2.5-5 is suitable for
floating source Analog Input signals.
Important Note: For the method illustrated in Figure 2.5-4, the maximum allowable common
mode voltage between the Analog Input source and the AGND pin is 70V
ensure that the input signal is below this level before continuing. If the common mode voltage is set
to above 70V
The easiest approach to selecting the most suitable configuration for the input signal connection is
outlined below:
1. Grounding the source input signal see Figure 2.5-1
2. Thermocouple input signal see Figure 2.5-4
3. Floating source input signal see Figure 2.5-5
4. If Vin > 1 V, and the gain is <=10 and more channels are needed see Figure 2.5-3
5. Current source input signal see Figure 2.5-6
, the input multiplexer will be permanently damaged.
p-p
, so care must be taken to
p-p
If the characteristics of the input signal are unknown or unclear, test the signal using the following
procedure to determine the most suitable method:
1. Measure the signal using the connection illustrated in Figure 2.5-1 and record the result
2. Measure the signal using the connection illustrated in Figure 2.5-5 and record the result
3. Measure the signal using the connection illustrated in Figure 2.5-3 and record the result
4. Compare the three results and select the most suitable connection method

6 I/O Control Registers
6.1 Determining the I/O Address
During the power-on stage, the Plug and Play BIOS will assign an appropriate I/O address to each
PCI-822/826 Series card installed in the system. Each PCI-822/826 Series card includes four fixed ID
numbers that are used to identify the card, and are indicated below:
The following functions are provided for the PCI-822/826 card:
1. PCI82x_DriverInit(&wTotalBoards)
This function is used to detect how many PCI-822 and/or PCI-826 cards are installed in the
system, and also records the I/O resource information for the card(s) in the library. The function
is implemented based on the PCI Plug and Play mechanism.
For example:
wTotalBoards = 1 there is only one PCI-822/826 Series card installed in the system
wTotalBoards = 2 there are two PCI-822/826 Series cards installed in the system

wConfigSpace[i][1]=wBaseDIO; // save all resource of this card
wConfigSpace[i][2]=wBaseDA; // save all resource of this card
wConfigSpace[i][3]=wBaseAD; // save all resource of this card
}
/* Step3: Control the PCI-822&PCI-826 directly */
outpw(wBaseDIO+0x0,wDoValue); // control the D/O states of card_0
wDiValue=inpw(wBaseDIO+0x0); // read the D/I states of card_0
outpw(wBaseDIO+0x0,wDoValue); // control the D/O states of card_1

6.4.3 Enable/Disable an Analog Output Channel
(Write)wBase+0x08 Enable/Disable an Analog Output Channel
D/A channel must be enabled or disabled before the voltage can be output to the channel. The D/A
channels are allocated as follows:
CH x = 1 Enable the channel
CH x = 0 Disable the channel
The following is an example of how to enable the Analog Output Channel:
//Set the AO Mode
outpw(wBaseDA+0x04,(WORD)(((wChannel/2)<<2)|(((wChannel%2)<<1)|(wChannel%2))));
//Write data to the D/A Port
outpw(wBaseDA +0x00,(WORD)(wValue&0xFFFF));
//Enable the D/A Port (only for the first D/A Output)
if((inpw(wBaseDA+0x08)&(0x1<<wChannel))==0)
{
outpw(wBaseDA+0x08,(WORD)(inpw((WORD)( wBaseDA+0x08))|(0x1<<wChannel)));

7 Calibration
Each PCI-822/826 Series card is already fully calibrated when shipped from the factory, including the
calibration coefficients that are stored in the onboard EEPROM, so it is usually unnecessary to
calibrate the board again unless the accuracy is lost. The procedure described below provides a
method that allows the board to be calibrated for a more precise application of voltages within the
system, so that the correct voltages for your field connection can be achieved. This calibration
method ensures that the effects of voltage drops caused by IR loss in the cable and/or the
connector can be eliminated.
Before beginning calibration, ensure that a precise multi-meter is available. Note that the calibrated
values for the Analog Input/Output channels are stored within three words in the address of the
EEPROM, as shown in the table below.
The calibration values stored in the EEPROM address are as follows:
Warning:
It is recommended that calibration is not performed until the process is fully understood.
Note: Ensure that a stable calibration source is used. An unstable calibration source will cause
calibration errors and will affect the accuracy of the data acquisition.
