Some decoders, particularly certain sound decoders, draw so much current that the reply pulse isn't detected by the command station. It could also be that the decoder doesn't support readback. It could be due to poor electrical connections to the programming track or within the locomotive. If that pulse isn't seen, some command stations provide this error message. If you do see this message, please report the circumstances on the JMRI users Group.Īt the end of a CV read or write operation, the locomotive replies ('acknowledges') to the command station using a pulse of current. In general, JMRI is pretty good at deciphering what went wrong, and this message isn't very common. DecoderPro generally will retry it successfully in that case.Īn error has happened, but JMRI doesn't know enough about it to be able to report more detail.

Once JMRI is working properly, this error may occasionally happen due to a transient error.

Picking the wrong serial port is particularly common. This could be a problem with the cable(s) making the connection, or a problem with how the preferences are set. In that case, it usually means that the connection to the command station isn't correct. This is by far the most common error message when people first start using JMRI. The program did not hear back from the command station when it expected to. It's considered an error because if the values don't match, we know that we don't know the correct value for the CV contents. If the value in the CV doesn't match the expected value, this message is issued.

In general, this is faster than doing a complete read. Some command stations allow you to 'confirm' the content of a CV, rather that read the value from it. This is considered an error, because the program doesn't know whether the decoder actually saw the operation complete or not. The user has requested that the read or write operation stop early. If you do see this message, please report the circumstances on the JMRI users Group. This is not supposed to happen, as JMRI should disable programming modes that the command station can't provide. This means that JMRI has requested the command station do something that it doesn't support.

Some DCC systems can't do ops-mode programming (programming on the main) while also using the service mode programming track, in which case they'll return this error message.ģ03 - requested not implemented in command station This usually means that some other part of the DCC system is doing a programming operation, e.g. The command station has reported that it's busy doing something else, and can't do any programming right now. This can happen if the locomotive isn't making good electrical contact or if there's a wiring fault in the locomotive. The command station has reported that it doesn't see a locomotive on the programming track.
