Issue Details

I am creating a board to connect to a Digital Instrument like the PCI-6542, but would not like to use a VHDCI connector on the board. Would you have a cable with VHDCI at one end for connecting to the PCI-6542, and SCSI or something other than VHDCI at the other end?


The recommended option is using an NI 653x Cable Adapter with C68-C68-D4 or SHC68-C68-D4 cables to connect to SCSI accessories.

Refer to the Digital Instruments Accessory Guide for the 653x Cable Adapter for more information on the 653x Cable Adapter and the Digital Instrument Cable and Accessory Compatibility for more information about cables and accessories for the PCI-6542 and other Digital Instruments.

Additional Information

  • The NI 653x Cable Adapter does a direct pass through of the VHDCI pinout, except for the Trigger and Control lines. These lines will need to be connected by use of the Screw Terminals inside the backshell of the cable adapter.
  • The 653x Cable Adapter is designed for use with the PCIe/PXIe 6535/6/7, the PCIe 6535B/6B/7B, the 654x series and the 655x series. It has not been tested and is not recommended for use with other NI products.
  • Alternatively, you can use the SHC68-H1X38 Flying-Lead Cable to connect to header pins on male connectors. However, the SHC68-H1X38 Flying-Lead Cable was designed for applications that demand quick probing and analysis of digital components or for environments where the hardware configuration constantly changes. It is not recommended to use it as an adapter like the NI 653x Cable Adapter.
