Chapter 1 Overview

1.1 Product introduction

PCI-1255 is a high-performance data acquisition product that is feature-rich and

cost-effective. Based on 32-bit PCI interface, PCI-1255 can provide 12-bit with max sampling rate

of 500kS/s, up to 32 channels analog data acquisition. Equipped with 16 digital input channels, 16

digital output channels, and 3 16-dit timer/counter channels, this is the best choice for you

weighing cost control and the speed of completion.

Figure 1.1 shows the block diagram of PCI-1255.

Chapter 2 Signal connection and configuration

2.1 Overview

Before installing the DAQ device, you need to know the functions and positions of all

connectors, tuners and jumpers on PCI-1255 device.

PCI--1225 is equipped with two signal connectors. The 37-pin D-type connecter on its front

panel is mainly used for analog input. The 40-pin IDC connector on its back panel is mainly sued

for digital IO signal connection.

There are specific tuners and jumpers for specific settings of analog input calibration,

channel input mode, and trigger. More detail about them are in later chapters.

Figure 2.1 shows relative connectors and their corresponding settings.

2.2 37-pin -type connection

The 37-pin D-type connector is used for connections to analog input channels and the 3 OUT

ports on 82C54. Figure 2.2 shows its pin details. In the case that no analog input channel is being

used, it is best to ground it to increase the measurement accuracy of the device as much as

2.5 Analog input range setting

Jumper JP1 is for the setting of analog input range, which can be set as 0~10V range or

-5~5V range as shown in Figure 2.5.

2.6 Analog input calibration

A new PCI-1255 DAQ card will be factory-calibrated as 32 channels singled ended input with

0~10V range. It can be deployed right after basic verification. If there is any change on channel

input or range, it must be calibrated once again to make sure the DAQ card can acquire the

correct data.

The analog input correction is divided into two steps: correcting the full scale and correcting

the zero point. The regulator VR1 is used to correct the full scale and VR2 is used to correct the

zero point.

Be aware that in the calibration process, do not touch any conductive parts on the DAQ card

to avoid damaging the card or the computer.

Correction steps：

1、Enter the maximum voltage value of the range you set to any one of the analog input

channels. Adjust the VR1 so that the DAQ card measurements just reach this maximum voltage.

2、Connect the analog input channel to the AGND, adjust the VR2 so that the measurement

value on the DAQ card is just 0V.

3、Repeat the above two steps a few times to get the best correction result.
