I need some wiring assistance. I have a PXI-2501 setup for 1-wire 48x1 with a TB-2065 terminal block. I have one analog signal coming into the block that I would like to switch between 5 separate LEDs. The incoming analog signal has two wires ( positive & GND ), and my LED bank has 6 wires ( 5 separate positives & one shared GND ). I have been examining the "NI Switches Help" documentation section "NI PXI-2501/2503 1-Wire 48×1 Multiplexer Topology," but have not quite figured it out. Should I tie my two ground wires together and then connect the rest as follows?
+1 -> terminal 27
output LED Bank
+1 -> terminal 67
+2 -> terminal 66
+3 -> terminal 65
+4 -> terminal 64
+5 -> terminal 65
Also, should I be connecting the GND wires to the block somewhere instead of to themselves?
Any help would be greatly appreciated...

Try moving the Analog Input + connection to terminal 61. You can a) tie your two ground wires together or b) can connect the ground wires to the TB-2605 terminal block.
The picture below shows the resulting configuration if you were to connect the ground wires to the terminal block:
Hope this helps!
