10777 (international)

Signal-ID: 77 (hex: 0x4D)

Using this signal configuration, the following signals can for example be operated:

DB exit signal
DB block signal
DB entry signal
DB stop signal
DB main signal + Zs2
DB main signal + Zs3 with Hp2
DB main signal + Zs3 with Hp1

This signal configuration can also be used to partly replace the Roco 10777 signal decoder which is to be discontinued. In comparison to the old decoder, however, this signal configuration offers additional optional outputs for the direction and speed displays Zs2 and Zs3. In the Z21 signal DECODER, however, four turnout addresses are reserved per signal, whereas only two turnout signals respectively were reserved on the 10777.
