MTS
MTS is an acronym for Multi-Train System, the digital system of LGB. While this
system does not feature the NMRA Conformance Warrant, it is designed to operate
according to NMRA DCC standards and recommended practices (RPs).

NMRA
NMRA is an acronym for the National Model Railroad Association. The NMRA sets
standards and recommended practices for NMRA DCC systems. NMRA DCC features
standardized communication protocol along the rails, offering interoperability between
manufacturers. The standardization and interoperability does not extend to devices
designed to operate on the bus system.

PoM = Programming on the Main, a.k.a. Operations Mode Programming
Traditional programming methods require moving the affected locomotive to an isolated
programming track.
Programming on the Main
or
Operations Mode Programming
allows the user to program the decoders of locomotives still sitting on the main
operating track. When using PoM, the user selects the locomotive address of the
decoder he wishes to program. Typically, the locomotive address CVs cannot be
changed with PoM. Please note some decoders are not compatible with PoM.
Massoth eMOTION XL/XLS decoders are compatible with PoM. LGB 55020, 55021,
55022, 55027 and LGB onboard decoders are not compatible with PoM.

Protocol
Protocol
is a set of conventions governing the formatting of data in an electronic
communications system. In essence, the system protocol is the communication
language
spoken between devices on an electronic network.

Speed Steps
In order to control the driving speed of the locomotive motor, the central station sends
direction
and
speed step
commands to the mobile decoder. In simple terms, each
speed step equates to a pre-set drive voltage for the motor. The drive voltage for each
of the decoder’s speed steps can be programmed by the user. The higher the number
of available speed steps, the greater the resolution of motor speed control. NMRA
DCC allows the central station to send 14, 28 and 128 speed step commands to mobile
(locomotive) decoders. Basic decoders (e.g., LGB 55020) and central stations (e.g.,
LGB 55000, 55005) only support 14 speeds steps. Massoth central stations and
decoders support 14, 28 and 128 speed steps.
