I/O Connector

NI 6510 I/O Connector

The 37-pin D-SUB connector on the NI 6510 provides access to the digital inputs. The digital
I/O available on this connector includes 32 inputs. For easy connection to the digital I/O
connector, use the National Instruments SH37F-37M shielded digital I/O cable with the CB-37F
connector block. For more information on digital I/O connectivity options, refer to Chapter 5,
Cables and Accessories.
Caution
specifications. Doing so could permanently damage the NI 6510 and the computer.
Refer to the NI 651x Specifications, available at
about maximum input ratings.
The input lines on the NI 6510 consist of input photocouplers, which react to a voltage
differential rather than only to a voltage increase. If the voltage connected to a digital input is
either greater than or less than the voltage connected to COM by at least the logic threshold, the
reading on the digital line will be logic high, even though in one instance the digital line has a
lower voltage level than COM.

NI 6511 I/O Connector

The 100-pin high-density SCSI connector on the NI 6511 provides access to the digital inputs.
The digital I/O available on this connector includes 64 inputs. For easy connection to the digital
I/O connector, use the National Instruments 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. For more information on digital I/O connectivity options, refer to Chapter 5,
Cables and Accessories.
