Technical Information

The E-MB1 from TCS is designed to replace the original lighting board in the any application where you can fit. Recommended fits include locomotives from InterMountain Railway, Bowser, LifeLike 1000 and 2000, Bachmann, and Broadway Limited. This motherboard will accept a 21-pin decoder and allow up to 12-function outputs.

The E-MB1 has been designed to meet NMRA standards, and is compatible with any NMRA-compliant 21-pin decoder with up to 8 lighting outputs, such as TCS’ WOW121 or EU821 decoders (sold separately). This motherboard can be used with LEDs thanks to on-board resistors. See the Lighting Wiring Instructions section below for detailed instructions.

Wiring Diagram

Shown below is the latest wiring diagram for the E-MB1. This diagram depicts the "Revision 1" version of the E-MB1, which is the current production version.

The wiring diagram above uses colors for inputs, outputs, and other functions as defined in the NMRA standards for Color Coded Wires.

Below is the wiring diagram for the adapter board that comes with the E-MB1

Wiring Instructions for LED Lights

Perform these steps below to connect LED lighting to the motherboard:

Step 1: Connect the Anode (+) wire from the locomotive to any available “V+” (BLUE) pad.
Step 2: Connect the Cathode (-) wire to the F0F (forward headlight), F0R (reverse headlight), or F1-F10 pads shown in the wiring diagram.

The E-MB1 comes with built in resistors on each function pad for LED lighting
