KB938: Programming with UT2 & DB150 Genesis II

This article was last updated on April 19, 2012, 4:10 p.m. | Print Article | Leave Feedback


To use the UT2 to program a decoder you must first put the UT2 in Programming Mode. To do this press and hold “RUN/STOP” and simultaneously press “PROG”. The Status LED will now turn a steady orange color indicating the UT2 is now in Programming Mode.

Set the locomotive you wish to program on an isolated programming track (See Section 5.2). Make sure that the DB150 command station is not connected to any other part of the layout. If you don’t have a programming track on your layout remove any locomotive you don’t want programmed at this time.

Decoders are programmed when the command station sends programming information to them through the rails. This information is sent as a broadcast message to any decoder that is listening. This means that you could reprogram all the locos on the track with one keystroke. To prevent this, it is useful to add an isolated programming track as described in Section 5.2.


Set Decoder Address

1. Set the rotary selectors to the desired address (01 – 98)

2. Press the “ADR” button to select and send that address to the decoder. The decoder will now answer to the new address.


Set Configuration Variables (CV’s)

1. Set the rotary selectors to the CV number that you wish to set, then press the “F1/CV#” button. This tells the decoder which CV you wish to change.

2. Once you have selected the CV you wish to change, use the rotary selectors to set the value of that CV. Now press “CV VL” to select and send that value for the CV previously selected. To change additional Configuration Variables, repeat steps 1 and 2 as many times as necessary.

3. To resume normal operation press “RUN/STOP” and “PROG” buttons simultaneously to take the UT2 out of Programming Mode.

4. Press "RUN/STOP" and "ON" to turn track power back on.
