software technologies such as multithreaded streaming technology for

dramatic improvements in I/O performance and ease of use.

• Use the DAQ Assistant to guide you to fast, accurate measurements

with no programming

• Use automatic code generation to create your application in

LabVIEW, ANSI C, Visual Basic .NET, or C#

• Take advantage of multithreaded streaming technology for

1,000X performance improvements

• Use automatic timing, triggering, and synchronization technology

to make advanced applications easy

jump-start your project

• Use NI-DAQmx functions for jumper-free software configuration of

all digital I/O features without hardware switches/jumpers

• Develop your application with easy and open programming in

LabVIEW, ANSI C, Microsoft Visual C++, C#, and Visual Basic .NET

Digital I/O Connector

The 100-pin high-density SCSI connector on NI 6509 devices connects to

100-pin ribbon cable or shielded cables. For low-cost unshielded connectivity,

use the R1005050 ribbon cable with two CB-50LP or CB-50 connector

blocks (a CB-100 kit). For shielded connectivity, use the SH100-100-F

shielded digital I/O cable with the SCB-100 connector block.

You can individually program each 8-bit port on an NI 6509 to

be input or output. The maximum input logic high and output logic high

voltage rating is -0.5 to +5.5 V with respect to GND. Pins 49 and 99 on

the I/O connector supply +5 V from the computer power supply through

a self-resetting fuse.
