Support - Resets

Question: My decoder is acting erratically/My decoder won't respond - How do I reset my TCS decoder to factory settings?

Factory resets on ALL TCS decoders are performed by programming CV 8 with a value of 2.

NOTE: CV 8 is what the NMRA defines to be a "Read Only" CV. What this means is that no value can be used to overwrite the value in this CV; however, TCS has defined several "macros," or sequences of operations which will be performed in the even specific vales are attempted to be programmed. For example, by programming a value of 2, a factory reset will be performed.

NOTE: Any TCS decoder manufactured on or after July 1st of 2019 support the use of values of 2 or 8 in CV 8 to perform a factory reset.

On TCS WOWSound Version 4 (and older) decoders, a "nuclear reset" can be performed by programming the following CV's:

• CV201 = 5
• CV202 = 0
• CV203 = 0
• CV204 = 8

A nuclear reset will change 100% of the configurations of the decoder. Due to time constraints in certain circumstances, a standard factory reset has been designed to ignore certain CV's and settings. The reset above will load User Preset 1, thereby overwriting everything. If no configurations were previously saved to User Preset 1, the decoder will be loaded will all default settings.

Before performing a factory reset, you may want to make you you have checked our section on Addressing first! In some situations, a full reset may not be necessary. If for example the issue(s) began after changing the decoder address, it is likely no other problems exist. To reset your decoder address only, ensure CV19 = 0, then Program CV1 to 3 on a Programming Track. Programming tracks ignore addresses and are the only way to resolve address issues. For other tiers of resets, such as resetting throttle buttons to their default sounds, Audio Assist can be used to reset certain parts of your configuration.
