1. Introduction
The PCIe-862x User Manual contains information about using the ICP DAS PCIe-862x Series data
acquisition (DAQ) boards with UniDAQ. PCIe-862x Series boards feature up to 16 Analog Input (AI)
channels, up to two Analog Output (AO) channels, up to 24 lines of digital input/output (DIO), and
two counters. This chapter provides basic information you need to get started using your PCIe-862x
Series boards.
1.1 Overview
The PCIe-8620/8622 is a powerful
multifunction board based on the PCI
Express. With a FIFO of 2048 samples, the
maximum sampling rate of PCIe-862x
Series is up to 200 kS/s with 8/16 16-bit A/D
converters simultaneously sampling on
each channel. The PCIe-862x Series has two
16-bit voltage output (D/A) channels, 4/12
digital input channels, 4/12 digital output
channels, and two PWM output channels.
PCIe-8620/8622 supports more kinds of trigger modes for A/D conversion: software trigger, internal
pacer trigger and external pacer trigger. The software trigger can acquire a sample whenever
needed, while the internal pacer saves CPU loading by triggering the sampling at pre-programmed
frequency. An external pacer can be used for triggering by external frequency source.
The PCIe-8620/8622 also includes an onboard Card ID switch that can be used to set a unique ID for
each board so that they can be instantly recognized if two or more boards are installed in the same
computer.

On PCIe-8620/8622, each channel uses its own instrumentation amplifier and A/D converter to
achieve simultaneous data acquisition. The main blocks featured in the PCIe-8620/8622 Analog
Input block are as follows:
CON1:
User can connect Analog Input signals to the PCIe-8620/8622 through the CON1.
ADC:
The analog-to-digital converter (ADC) digitizes the AI signal by converting the analog voltage
into a digital number.
FIFO:
PCIe-862x Series can perform A/D conversion of a fixed or infinite number of samples. A large
first-in-first out (FIFO) buffer holds data during AI acquisitions to ensure that no data is lost.
PCIe-862x can handle A/D conversion operations with DMA or programmed I/O.

2.4.2 Analog Input Range
Input Range refers to the set of input voltages that an Analog Input channel can digitize with the
specified accuracy. The PGA amplifies or attenuates the AI signal depending on the input range. User
can individually program the input range of all channels on PCIe-862x Series board.
Input rage affects the resolution of the PCIe-862x Series for an AI channel Resolution refer to the
voltage of one ADC code. 16-bit ADC converts Analog Inputs into one of 65,536 (=216) codes –that
is, one of 65,536 possible digital values. These values are spread fairly evenly across the input range.
For an input range of -10 V to 10 V,
the voltage of each code of a 16-bit ADC is 10 V - (-10 V) / 65536 = 305 μV
For an input range of -5 V to 5 V,
the voltage of each code of a 16-bit ADC is 5 V - (-5 V) / 65536 = 152 μV

2.4.5 Analog Input Data Acquisition Methods
The following is an overview of the five trigger modes:
Trigger Mode
Description
Software
Trigger
No trigger signal is used
and all A/D operations
are initiated by software.
Post Trigger
DTRG0 trigger signal is
used to initiate the
A/D operations.
After the clock signal is generated, A/D data will be recorded and saved to the buffer or the FIFO.
Two clock sources are provided, a software command and a pacer clock.
The saved data can be transferred to the memory on the PC using either software polling, Interrupt
transfer or DMA transfer.
Different combinations of trigger mode, clock signal and data transfer can be used to create four
different types of A/D applications, which are summarized below:
