NI PXI-2501 1-Wire 48×1 Amplified Multiplexer Topology
When using the NI PXI-2501 as a 1-wire 48×1 amplified multiplexer, connect your signals using the NI TB-2605 terminal block. The following figure is a representation of the NI PXI-2501 in this mode.
The NI PXI-2501 in this topology operates the same way as the 1-wire 48×1 multiplexer topology except that an amplifier, indicated in the figure above, can be used.
