PoM
Braking mode:
Bit 0 - 3 : always 0,
Bit 4 : DC voltage, polarity against the direction of travel
Bit 5 : DC voltage, polarity with the direction of travel
Bit 6 - 7 :
0 - 48
0
0 / 16
0 / 32
0

Braking subject to direction:
- only Bit 4 : normal DC properties
- only Bit 5 : inverse DC properties
Braking not subject to direction:
- Bit 4 + 5 : 3 rail properties

PoM
Configuration:
Bit 0 : reverses direction properties of the locomotive
0 = normal direction, 1 = inverse direction
Bit 1 : speed level 14 or select 28/128
0 = 14 speed levels, 1 = 28/128 speed levels
Bit 2 : turn analog operation off/on
0 = analog off, 1 = analog on
Bit 5 : select short / long address
0 = short address, 1 = long address

The direction properties refer to the
direction of travel and the lights. The
number of speed levels and the light bit
depend on the locomotive controller.
Either the short main address or the
long expanded address as a locomotive
address.
CV Table for DCC
PoM must be supported by the locomotive controller / central controller.
