M Series User Manual

68-Pin Cables

Cabling options differ between the 68-pin PCI/PCI Express/PXI/PXI Express devices and

modules and USB Mass Termination devices.

PCI/PCI Express/PXI/PXI Express Device/Module 68-Pin Cables

You can use the following cables with PCI, PCI Express, PXI, and PXI Express M Series devices

and modules:

• SHC68-68-EPM

—(Recommended) High-performance shielded cable designed for

M/X Series devices. It has individual bundles separating analog and digital signals. Each

differential analog input channel is routed on an individually shielded twisted pair of wires.

Analog outputs are also individually shielded.

• SHC68-68—(Recommended) Lower-cost shielded cable with 34 twisted pairs of wire. The

cable is recommended for PCI/PXI-6225/6255 Connector 1.

Note You must use the SHC68-68 cable on Connector 1 of PCI/PXI-6225/6255

devices and modules. The SHC68-68-EPM cable can be used on Connector 0 of all

M Series PCI, PCI Express, PXI, and PXI Express devices and modules, and on

Connector 1 of NI PCI/PCIe/PXI/PXI-6224/6229/6254/6259/6284/6289 devices and

modules.

• RC68-68—Highly-flexible unshielded ribbon cable.

USB Mass Termination Device 68-Pin Cables

You can use the following cables with USB devices with mass termination connectors:

• SH68-68-EPM

—(Recommended) High-performance cable with individual bundles

separating analog and digital signals. Each differential analog input channel is routed on an

individually shielded twisted pair of wires. Analog outputs are also individually shielded.

• SH68-68-S—(Recommended) Shielded cable with 34 twisted pairs of wire. Each

differential analog input channel on Connector 1 is routed on a twisted pair on the

SH68-68-S cable. The cable is recommended for USB-6225/6255 Mass Termination

Connector 1.

Note You must use the SH68-68-S cable on Connector 1 of USB-6225/6255

Mass Termination devices. The SH68-68-EPM cable can be used on Connector 0 of

all M Series USB Mass Termination devices, and on Connector 1 of

USB-6229/6259/6289 devices and modules.

• R68-68—Highly-flexible unshielded ribbon cable.

NI recommends that you use the SHC68-68-EPM cable; however, an SHC68-68-EP cable works with

PCI/PCI Express/PXI/PXI Express devices and modules.

NI recommends that you use the SH68-68-EPM cable; however, an SH68-68-EP cable will work with

USB Mass Termination devices.
