The DT402/DT402 series throttles have displays which give you information about the performance of your railroad.
The decoder address selected on the L Throttle is displayed on the bottom line of the LCD to the left of the Mode Indicator. The decoder address selected on the R Throttle is displayed on to the right of the Mode Indicator. The address can show as either the 2-digit or the 4-digit decoder address. If no address is selected the display will show “SEL.” If a 2-digit address is selected (00-127), the display will show two or three digits. If a 4-digit address is selected (0128 - 9983), the display will show all four digits including the leading zero.
