42-Pin Male Nano-Pitch to 42-Pin Male Nano-Pitch, Shielded OCuLink Cable—The SH42MNano-Pitch-42MNano-Pitch OCuLink Cable, sometimes referred to as OCuLink x4, 1M - Nano-Pitch, connects multisignal DIO connectors on RF and FlexRIO devices to other NI devices or accessories like the SCB-8 breakout connector. The cable acts as a data communication interface and provides access to FPGA multi-gigabit transceivers (MGTs) and/or general-purpose LVCMOS signals from the NI device.
