NI PXI-2584

The NI PXI-2584 is a high-voltage multiplexer switch module for the PXI platform. The NI PXI-2584 uses reed relays.

A number of factors can affect the life expectancy of reed relays. Refer to Reed Relay Protection for information about protecting the reed relays of the NI PXI-2584.

For certain applications, you may need to increase the default settling time. Refer to Adding Additional Settling Time for more information.

You can use the reference (REF) connections on the NI PXI-2584 to reduce noise and preserve signal integrity in 1-wire topologies. Refer to Signals Connections for more information about REF connections.

Operation Modes

The following table lists the supported topologies of the NI PXI-2584 and possible operation modes.

Topology	Software Name	Immediate	Scanning
1-Wire Dual 6×1 Multiplexer	2584/1-Wire Dual 6x1 Mux (NISWITCH_TOPOLOGY_2584_1_WIRE_DUAL_6X1_MUX)
1-Wire 12×1 Multiplexer	2584/1-Wire 12x1 Mux (NISWITCH_TOPOLOGY_2584_1_WIRE_12X1_MUX)
2-Wire 6×1 Multiplexer	2584/2-Wire 6x1 Mux (NISWITCH_TOPOLOGY_2584_2_WIRE_6X1_MUX)
Independent	2584/Independent (NISWITCH_TOPOLOGY_2584_INDEPENDENT)

Tip  Use the Independent topology to configure the NI PXI-2584 for interleaved functionality. The user-implemented interleaved functionality is useful when measuring stacked signals—for example, battery stacks.
