NMRA CV 28 - Bi-Directional Communication Configuration (RailCom®)

This CV is used to configure decoder’s bi-directional communication characteristics when RailCom is enabled in CV 29.
Note: If the decoder does not support a feature contained in this table, it shall not allow the corresponding bit to be set improperly. E.G. if a decoder does not support RailCom, this CV will read 0 and will not accept any values to be programmed to it.

Feature Description Default Value
Channel 1 If enabled, Channel 1 will broadcast the address. ON 1
Channel 2 If enabled, Channel 2 will send and receive data and provide acknowledgements. ON 2
Programming Address 253 Serves as a programming lock. If this setting is disabled, programming address 253 will be locked. ON 16
