Caution
This NI product must be operated with shielded cables and accessories to
ensure compliance with the Electromagnetic Compatibility (EMC) requirements
defined in the
Specifications
section of this document. Do not use unshielded cables
or accessories unless they are installed in a shielded enclosure with properly designed
and shielded input/output ports and connected to the NI product using a shielded
cable. If unshielded cables or accessories are not properly installed and shielded, the
EMC specifications for the product are no longer guaranteed.
The 100-pin high-density SCSI connector on the NI 6509 provides access to 96 digital inputs
and outputs. Use this connector to connect to external devices, such as solid-state relays (SSRs)
and LEDs. For easy connection to the digital I/O connector, use the SH100-100-F shielded
digital I/O cable with the SCB-100 connector block, or use the R1005050 ribbon cable with the
CB-50 or CB-50LP connector block.
Caution
Do not make connections to the digital I/O that exceed the maximum I/O
specifications. Doing so may permanently damage the NI 6509 device and the
computer. Refer to the
Signal Descriptions
and
Specifications
sections for
information about the maximum I/O specifications.
