Feature Details

PCI-Bus Mastering Data Transfer

PCI-1716 and PCI-1716L support PCI-Bus mastering DMA for high-speed data transfer

and gap-free analog input and analog output. By setting aside a block of memory in

the PC, PCI-1716 and PCI-1716L performs bus-mastering data transfers without CPU

intervention, setting the CPU free to perform other more urgent tasks such as data analysis

and graphic manipulation. The function allows users to run all I/O functions simultaneously

at full speed without losing data.

Auto-calibration Function

PCI-1716 and PCI-1716L provide an auto-calibration function by using a calibration

utility. The built-in calibration circuitry of the PCI-1716 and PCI-1716L corrects gain and

offset errors in analog input and analog output channels thereby eliminating the need for

external equipment and user adjustments.

BoardID™ Switch

PCI-1716 and PCI-1716L have a built-in BoardID™ DIP switch that helps deﬁne each

card’s unique identity when multiple identical PCI cards have been installed in the same

computer. The BoardID switch is very useful when you build your system with multiple

identical PCI cards. With the correct BoardID switch settings, you can easily identify and

access each card during hardware conﬁguration and software programming.

Plug & Play Function

PCI-1716 and PCI-1716L are Plug & Play devices, which fully complies with PCI

Speciﬁcation Rev 2.2. During card installation, there is no need to set jumpers or DIP

switches (Unless you are using several identical cards (See BoardID switch)). Instead,

all bus-related conﬁgurations such as base I/O address and interrupt are automatically

done by the Plug & Play function.

Automatic Channel/Gain/SD*/BU* Scanning

PCI-1716 and PCI-1716L feature an automatic channel/gain/SD/BU scanning circuit. This

circuit controls multiplexer switching during sampling in a way that is more efﬁcient than

software implementation. On-board SRAM stores different gain, SD and BU values for

each channel. This combination lets users perform multi-channel high-speed sampling

with different gain, SD and BU values for each channel.

SD: Single-Ended/Differential; BU: Bipolar/Unipolar

On-board FIFO Memory

PCI-1716 and PCI-1716L provide 1K sample on-board FIFO (First In First Out) memory

buffer for AD. This is an important feature for faster data transfer and more predictable

performance under the Windows system.

On-board Programmable Timer/Counter

PCI-1716 and PCI-1716L provide a programmable timer counter for generating a pacer

trigger for the A/D conversion. The timer/counter chip is 82C54, which includes three

16-bit counter 10 MHz clocks. One counter is used as an event counter for counting

events coming from the input channel. The other two are cascaded together to make a

32-bit timer for a pacer trigger time base.
