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.
