The WOW121 is a universal sound decoder designed for locomotives with DCC-ready 21-pin MTC connectors. It can also be used with any of TCS' motherboards. Please note: The WOW121 requires a motherboard to interface with the locomotive. The motherboard determines the number of lighting functions supported, as well as the type of lighting (LED or 12V/1.5V bulbs). A WOW121 decoder supports up to 8 lighting functions.

Important Note:

• Functions 5 and 6 are not programmable and will only output constant bright lights. Keep this in mind when wiring multiple lighting functions.
