PCIE-1816_1816H User Manual 2
The PCIE-1816/1816H is a PCI Express multifunction card for IBM x86 or compatible
computers. It offers the five most desired measurement and control functions:
 16-bit AI conversion
 16-bit AO conversion
 Digital input
 Digital output
 Timer/counter.
A programmable-gain instrument amplifier lets you acquire different input signals
without external signal conditioning. An onboard 4k word FIFO buffer provides high-
speed data transfer and predictable performance under Windows. Automatic channel
scanning circuitry and onboard SRAM lets you perform multiple-channel AI conver-
sion and individual gains for each channel.
The following sections of this chapter will provide further information about features
of the multifunction cards, together with some brief information on software and
accessories for the PCIE-1816/1816H cards.
1.1 Features
 16 single-ended or 8 differential AI inputs, programmable
 16-bit AI converter, up to 1 MHz sampling rate for PCIE-1816
 16-bit AI converter, up to 5 MHz sampling rate for PCIE-1816H
 Double-Clock acquisition operation for analog input
 Start-, Delay to Start-, Delay to Stop-, Stop-event trigger capable
 Programmable gain for each input channel, automatic channel/gain scanning
 4K onboard ring buffer for analog input and output
 Two independent 16-bit analog output channels with continuous waveform out-
put function of maximum 3 MHz throughput rate
 Auto-Calibration for analog input and output channels
 24 digital Input or output channels, TTL compatible
 Two 32-bit independent full function counters
 BoardID switch
PCIE-1816/1816H offers the following main features:
PCIe-Bus Plug & Play
The PCIE-1816/1816H card uses a PCIe controller to interface the card to the PCI
Express bus. The controller fully implements the PCI bus specification Rev 2.2. All
configurations related to the bus, such as base address and interrupt assignment,
are automatically controlled by software. No jumper or switch is required for user
configuration.
Automatic Channel/Gain Scanning
The PCIE-1816/1816H features an automatic channel/gain scanning circuit. This cir-
cuit, instead of your software, controls multiplexer switching during sampling. On-
board SRAM stores different gain values for each channel. This combination lets
user perform multi-channel high-speed sampling for each channel.
Onboard Ring Buffer Memory
There are 4k sample ring buffers for AI and AO on PCIE-1816/1816H. This is an
important feature for faster data transfer and more predictable performance under
Windows.
