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.
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. Additionally, the decoder should not allow you to enable a feature within the table below which is not supported.
| Bit | Feature | Description | Default | Value | Supported by TCS |
|---|---|---|---|---|---|
| 0 | Channel 1 | If enabled, Channel 1 will broadcast the address. | ON | 1 | YES |
| 1 | Channel 2 | If enabled, Channel 2 will send and receive data and provide acknowledgements. | ON | 2 | YES |
| 2 | Auto Channel 1 | Automatically Turn off Channel 1 | OFF | 4 | |
| 3 | (Reserved) | Not Used | N/A | 8 | |
| 4 | Programming Address 253 | Serves as a programming lock. If this setting is disabled, programming address 253 will be locked. | ON | 16 | YES |
| 5 | (Reserved) | Not Used | N/A | 32 | |
| 6 | Current Limit | If enabled, the higher current limit for RailCom will be enabled | OFF | 64 | |
| 7 | Automatic Login | If enabled, allows automatic login | OFF | 128 |
Note: The table above is based upon the RailCom Specification RCN-217 as of 12-12-2021 and as such is potentially subject to change. Additionally, the last column in this table "supported by TCS" is only true for current production decoders which support RailCom, and may be untrue for specific decoders and/or decoder versions (CV 7, or CV 110/CV 111) designed using an older revision of RCN-217.
