On the flip side, this also means that a decoder will also always accept and ac upon any programming instruction(s) received, regardless of its ability to provide an effective acknowledgment. What does this mean? What this means, is that a command station or dedicated decoder programmer will always send programming commands, regardless of whether or not a decoder provides an acknowledgement. Service Mode instructions can be executed regardless of whether or not the acknowledgment mechanism is detected by the command station/programmer." Acknowledgment refers to the ability of the Digital Decoder to respond to a Service Mode instruction issued by a Programmer. "Service Mode operations provide for an acknowledgment mechanism from the decoder to the command station/programmer.

For instructions on how to check your motor connections, visit the Multimeter Troubleshooting Guide on our website.Įxcerpt from S-9.2.3, Section D of the NMRA Standards and Recommended Practices: Shorts across the motor at this point can damage your decoder's motor outputs making them permanently unresponsive or run away! Open circuits will result in a similar lack of acknowledgement, and will also display an error on your system, but will not damage a decoder.

Therefore, it is important to make sure your motor connections are made and that they are free of short or open circuits. Similarly, the decoder cannot communicate a CV value when requested that it be read. If no motor is connected to the decoder, the decoder has no means by which it can "acknowledge" that a programming command has completed. In order to communicate with the command station, a DCC decoder needs to generate a spike of current. Problem 2: The motor is not connected to the decoder. In our experience, the PTB-100 from Soundtraxx is a reliable option when used with our decoders and Keep Alive® devices.
This issue can be solved in most cases with a programming Booster. The system may report errors such as "No Decoder," "No Ack," "No D," "No CV," etc. This will result in erratic and periodic results of success or failure when reading or writing CV's on the programming track. This is an issue especially for sound decoders or decoders with Keep Alive® which require more "juice" to program. Some systems on the market do not supply enough power for enough time on the programming track to allow for a programming operation to successfully take place. Problem 1: Trying to program a sound decoder on a low-power program track without a booster. There are a few reasons why your command station may not be able to read CV values. Question: My command station says it cannot read, or has failed to write, the CV's in my TCS decoder. 2.1.2 Reason 2 - Decoder Definition Missing.2.1.1 Reason 1 - Technical/Electrical Issue.2.1 JMRI Cannot Identify Decoder Type/Model.1.4 Problem 4: The programming track is not physically connected to the programming track outputs from the command station.1.3 Problem 3: Locomotive is not on the programming track.1.2 Problem 2: The motor is not connected to the decoder.1.1 Problem 1: Trying to program a sound decoder on a low-power program track without a booster.
