Overview and Applications

Pattern I/O and Handshaking I/O

With pattern I/O, you can input or output

patterns under timing control of a clock

BUY ONLINE!

The NI 653x devices are high-speed, 32-bit, parallel, digital I/O

interfaces for PCI, PXI, PCMCIA, and ISA. They incorporate the

National Instruments DAQ-DIO ASIC, speciﬁcally designed to deliver

high performance on plug-in DIO devices. The NI 653x devices perform

unstrobed I/O, pattern I/O, and handshaking at speeds up to

20 MHz, or 80 Mbytes/s for 32-bit transfers (NI 6534). The NI 6534

family delivers digital I/O coupled with large onboard memory for high-

speed pattern I/O at deterministic rates.

signal. When using handshaking I/O to interface your NI 653x to a

peripheral device, data is transferred when both the NI 653x and the

peripheral are ready. See page 376 in the Digital I/O overview and

page 787 in the Digital I/O tutorial for more information.

Change Detection

You can program the 653x devices to acquire data when one or

more user-speciﬁed digital input lines changes state. See page

377 in the Digital I/O overview and page 787 in the Digital I/O

tutorial for more information.

Features

Data Latches and Drivers

The 32 digital I/O lines are divided into four 8-bit ports. For pattern

I/O or handshaking, the ports can be grouped into two 8-bit or

16-bit groups, or a single 32-bit group. When conﬁgured for output,

each data line can sink or source up to 24 mA when set logic low or

high, respectively. When conﬁgured as inputs, the 653x data lines

are diode-terminated to dampen the input signals at TTL levels.

When performing static or unstrobed I/O, you can individually

conﬁgure each of the 32 I/O lines as input or output.

(for 6534 only)

With NI-DAQ driver software, you can conﬁgure your devices

interactively, write custom programs, and perform digital I/O

transfers easily. With NI-DAQ, the NI 6533 and NI 6534 devices

are software-compatible, providing a seamless upgrade path.

Sharing clocks and triggers between NI 653x and other

measurement devices is also greatly simpliﬁed. To get you started

with your application quickly, NI-DAQ includes numerous example

programs for LabVIEW and other ADEs.

Digital input/output lines

Handshaking, timing

You can develop event-driven application programs with NI 653x devices

by programming them to generate a message when conditions you

specify are met. The messages can be generated when a speciﬁed

number of bytes have been transferred, when a speciﬁed input pattern

is matched, or when a measurement operation completes.

Onboard Memory

Table 2. Signal Names and Descriptions

NI 6534 devices provide two groups of 32 MB of onboard memory, so

you can perform pattern I/O at deterministic high rates as long as the

patterns can ﬁt in one of these memory locations. To improve system

performance for repetitive pattern output applications, you can load

your patterns into the onboard memory once and then output them

repeatedly, without reloading them across the computer bus.
