WOW121-Diesel - UPGRADE

This upgrade program will update your WOW121-Diesel decoder to the latest production version available from TCS. Simply unplug the decoder from the motherboard/lighting board and ship your decoder in a small box along with the order confirmation you will receive via email.

Upon receiving your decoder, TCS will perform a hardware and software analysis including a Version check and will update and/or replace the decoder to bring it up to the latest version.
We will do our best to get your decoder(s) turned around as quickly as possible.

Never miss out on a new Prime Mover, Bell, or Horn!
