The UTP cab bus panel provides a low cost means of adding walk around capability to your layout. The panel has 4 RJ-12 connectors wired in parallel, two on the front and two on the rear. Your cab bus can be “daisy chained” from one panel to the next using the rear connectors. One or two cabs can then be plugged in to the front connectors. Please note the “Command Station” side versus the “More UTP panels” side in Figure 1 when wiring your panels. The UTP can also be used as a cab bus splitter. see the diagrams below
If any cab bus item is 30 feet of cable or more from the command station you will need to inject power into the cab bus to make sure a clean signal of minimum 8v gets out to the the devices on the cab bus.

If you have a regular UTP but want to add the P114 for added cab bus power, you will need to hack off the end and add the male 1/8inch (3.5mm) (Mono mini headphone plug) or solder the P114 directly to the board
5240234 UTP-Cat5 Additional power for the Cab Bus can be added to the socket in between the Cat5 sockets. We suggest a 1/2 to 2 Amp, 12 to 14Volt, Regulated DC power supply such as the NCE P114. (5.5/2.5mm plug center +)
