CV
Explanation
19
Multiple unit address
21
PoM
Functions F1 - F8 when using multiple unit
22
PoM
Functions FL, F9 - F15 when using multiple unit
Braking mode:
Bit 0 - 3 : always 0,
PoM
27
Bit 4 : DC voltage, polarity against the direction of travel
Bit 5 : DC voltage, polarity with the direction of travel
Bit 6 - 7 : always 0
Configuration:
Bit 0 : reverses direction properties of the locomotive
0 = normal direction, 1 = inverse direction
Bit 1 : speed level 14 or select 28/128
29
PoM
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
PoM must be supported by the locomotive controller / central controller.

Notes
1 - 127 = multiple unit address
0 = no multiple unit
+128, Bit 7 = reverse polarity for direction
when using multiple unit
0 = func. # only for locomotive address
1 = func. # also for multiple unit address
Bit 7-0 = [ F8 F7 F6 F5 F4 F3 F2 F1 ]
0 = func. # only for locomotive address
1 = func. # also for multiple unit address
Bit 7-0 = [ F15 F14 F13 F12 F11 F10 F9 FL ]
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
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.
