DT402 & DT400 Series Throttle-Locomotive Recall

The DT402 & DT400 Series Throttles store the last 4, 8,or 16 unique loco addresses used by the throttle in a recall stack; your throttle defaults to a 4 address recall stack. 

Users often discover this feature when taking their throttle for use on another Digitrax railroad; they plug their throttle into the new LocoNet and discover their own locomotive addresses are still in their throttle.  The presence of stored locomotive addresses may make operations on your railroad easier.

For example if you have your throttle set up for an 8 deep recall stack and the last 8 addresses you selected were: 00, 1987, 52, 0678, 03, 8819, 25, and 2500, these addresses will be in the recall stack. If you have selected any of these addresses more than once, it will not be stored twice, only the addresses not already stored will be added to the stack. The recall stack is not stored in numeric order. This makes it convenient to select locos that you have used previously without having to dial up the address.

To Recall the last 4, 8, or 16 addresses on the R Throttle


1. Press and hold the R Throttle knob. The word Recall will appear in the text line.

2. When Recall appears in the display, release the knob. RE will appear in the mode indicator in the center of the bottom line on the LCD. The right side address display will begin to flash prompting you to select a locomotive.

3. Turn the R throttle knob to browse through the last 4, 8, or 16 addresses selected in the system. Whether you browse 4, 8 or 16 addresses depends on how you set up your throttle's options. As you browse through the addresses, the throttle will display their current speed on the bar graph and their status in the text line of the LCD. Addresses are displayed in the order they were used by the throttle (not in numeric order).

4. Press and release the R Throttle knob or the LOCO Key to select the desired loco address. Once the locomotive is selected the R Throttle knob will be able to control the speed control and direction
of that locomotive.

Follow the same procedure to Recall a locomotive on the L Throttle by using the L throttle knob.
