PCI-1711U/UL offers the following main features:
PCI-Bus Plug & Play
The PCI-1711U cards use a PCI controller to interface the card to the PCI
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
PCI-1711U/UL features an automatic channel/gain scanning circuit. This
circuit, 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
(up to 100 kHz) for each channel.
Onboard FIFO Memory
There are 1K samples FIFO for A/D (AI) on PCI-1711U/UL. This is an
important feature for faster data transfer and more predictable perfor-
mance under Windows system.
