Multifunction Boards

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.

2.2 Jumper Settings

PCI-822/826 Series cards include a number of jumpers that can be used to configure features such as

the Analog Input/Output Type, the Analog Output Range, and the Digital Input/Output mode, etc.

each of which is described in more detail below.

2.2.1 JP1 (Analog Input Type)

Jumper JP1 is used to configure the Analog Input type as either single-ended or differential. To

configure single-ended input, connect pin1 to pin 3 and pin 2 to pin 4, as illustrated in the diagram

below. The default configuration is single-ended.

2.2.2 JP6/JP7 (Analog Output Range)

Jumpers JP6 and JP7 are used to configure the output range for Analog Output channel 0 and 1,

respectively. Connecting pins 1 and 2 sets the output range to -10 V to +10 V or 0 to +10 V, while

connecting pins 2 and 3 sets the output range to -5 V to +5 V or 0 to +5 V. The default configuration

is ± 10 V.

2.2.3 JP3/JP5 (Analog Output Type)

Jumpers JP3 and JP5 are used to select the Analog output type. Connecting pins 1 and 2 sets the

output type to Bipolar, while connecting pins 2 and 3 sets the output type to Unipolar. The default

configuration is Bipolar.

2.2.4 JP4 (Digital I/O Mode)

The JP4 Jumper block is used to configure the Digital Input/Output mode as either Jumper

Selectable or Software Programmable Mode. Connecting pins 1 and 2 of DIO-S0 sets the DI/O

mode to Jumper Selectable Mode, while connecting pins 2 and 3 sets the DI/O mode to Software

Programmable Mode. The default configuration is Jumper Selectable Mode.

 Software Programmable Mode:

Refer to “Section 6.3 Bar1: Digital I/O Registers” for details of how to configure Port A (PA) and Port

B (PB) when the jumpers for DIO-S0 is set to Software Programmable Mode. The jumpers for DIO-S1

and DIO-S2 are not used when the DIO-S0 is set to Software Programmable Mode.

Jumper Selectable Mode. The default configuration is Digital Input.

2.2.5 JP8 (Digital Input Pull-high/low)

Jumper JP8 is used to set the Digital Input to either Pull-high or Pull-low, which allows the status of

the Digital Input to be predefined instead of remaining floating if the Digital Input channels are

disconnected or interrupted. Connecting pins 1 and 2 will set the Digital Input to Pull-high. To set

the Digital Input to Pull-low, pins 2 and 3 should be shorted. The default connected is Pull-low.

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

CAUTION: The maximum allowable common mode voltage between the Analog Input source

and the A.GND pin for the connection shown in Figure 2.5-4, is 70 V

Example: A 20 mA source current through a 125 Ω resistor (e.g. 125 Ω, 0.1% DIP Resistors) between

+ and – terminals and the board will read a 2.5 VDC voltage. You can use the I = V/R (Ohm’s law) to

calculate what value the source current should have.

Current (I) = Voltage (V) / Resistance (R)

Note:

As certain operating systems, such as Windows 2000 and Windows XP may require the computer

to be restarted after a new driver is installed, it is recommended that the driver is installed first,

which will reduce the time required for installation.

3 Hardware Installation

To install your PCI-822/826 Series card, follow the procedure described below:

Step 1: Install the driver for the PCI-822/826 Series card on the computer.

For more detailed information

about installing the driver for the

PCI-822/826 Series card, refer to

Chapter 4 Software Installation.

Step 2: Configure the Jumpers and the SW1 DIP Switch on the PCI-822/826 Series card

depending on the required configuration.

For more detailed information about the configuring the

Jumpers and Card ID (SW1), refer to Section 2.2 Jumper Settings

and Section 2.3 Card ID Switch.
