2. Select the lowest possible voltage setting on your DB150. Select the N-scale setting on the "Scale" switch.

3. Set up your transformer to power the booster. Connect the power leads from the transformer to the DB150's "POWER IN" terminals but do not turn on the transformer yet.

1. Connect the protection resistor to the RAIL A output on the booster. Connect one end of the large resistor from the test kit to the BLACK output terminal labeled RAIL A. This connection protects your Digitrax decoder from ANY subsequent wiring errors as long as no other connection is made to the "RAIL A" terminal.

2. Connect the free end of the large resistor to the decoder's Right hand power input lead (RED).

3 Use a wire to connect the BLACK output terminal labeled RAIL B on the DB50 (or other compatible booster) to the decoder's Left hand power input lead (BLACK). This is the "protected" power input to the decoder. This arrangement limits the track power available that could cause damage to an incorrectly wired decoder.

1. Connect the RED/YELLOW lead of the LT-1 to your decoder's Motor + lead (ORANGE).

2. Connect the BLACK/GREEN lead of the LT-1 to the decoder's Motor - lead (GRAY). Make sure none of the decoder leads is shorted to ANY other lead.

3. We strongly recommend that you temporarily tape the other leads out of the way. These should be taped to a non-metallic bench or table top. This procedure will prevent unexpected results from leads shorting together.

4. Turn on the booster power. On the DB150, set the MODE switch to the RUN position. Connect the power leads to the power pack & switch the power pack on.

5. Turn on your command station. Connect the UT2 to either LocoNet A or B and the Track Status LED will come on. If it does not, then press and hold "RUN" and "ON" until it does.

7. Send speed commands to the decoder.

Turn the knob on the UT2 clockwise and one of the LED's on the LT-1 will glow if the decoder is functioning properly.

8. Send direction change commands to the decoder. Throw the toggle switch on the UT2 to change direction. The other LED on the LT-1 should glow showing that the decoder has received the change of direction command.

9. If the test LED does not light up, try programming the decoder to address 03 then re test the decoder. If this does not work contact Digitrax for a replacement.

1. Turn off track power. On the UT2 press "RUN" and "OFF" to turn of the track power.

2. Disconnect the GRAY & ORANGE decoder leads from the LT-1. Attach the BLACK/GREEN lead of the LT-1 to the wire that is connected to the decoder Left power lead (BLACK). Connect the RED/YELLOW lead of the LT-1 to the Forward light lead from the decoder (WHITE). Be sure that all leads not being used are secured and not touching each other.

1. Turn OFF the track power by pressing and holding down the UT2 "RUN" and "OFF" keys until the track status LED goes off.

2. Disconnect the decoder light leads from the LT-1 leads. Attach the BLACK/GREEN lead of the LT-1 to the wire that is connected to the decoder Left power lead (BLACK). Connect the RED/YELLOW lead of the LT-1 to the function output to be tested (Green=Function 1, Violet=Function 2, & Brown=Function 3). Test one function at a time. Be sure that all leads not being used are secured and not touching each other.

3. Use your command station to send function commands to the decoder. Use the UT2 to turn track power back on buy pressing the "RUN" and "ON" keys together. Then press the appropriate function button to test the lead selected. One LED on the LT-1 should glow when the function button is pressed.

4. Press and hold "RUN" and "OFF" on the UT2 to turn OFF track power each time you change the function lead to test a different function.
