7. Turn power to the system OFF. Disconnect the decoder’s white wire from the red lead of the test LED. Now
connect the red lead to the yellow decoder wire (reverse light).
8. Turn on power to the system. Using your DCC controller, turn on Function 0 and set the throttle direction to
reverse. The Bipolar LED should light. Turn Function 0 off and the LED should turn off
9. Turn power to the system OFF.
10.Disconnect the yellow lead of the decoder from the red wire of the test LED. Connect the red lead of the test LED
to the decoder’s green lead (F1 output). Make sure no other decoder leads are shorted to any other leads.
11.Turn on power to the system. Using your DCC controller, turn on Function 1. The Bipolar LED should light. Turn
Function 1 off and the LED should turn off.
12.Turn power to the system OFF.
13.Disconnect the green lead of the decoder from the red wire of the test LED. Connect the red lead of the test LED
to the decoder’s brown lead (F5 output). Make sure no other decoder leads are shorted to any other leads.
14.Turn on power to the system. Using your DCC controller, turn on Function 5. The Bipolar LED should light. Turn
Function 5 off and the LED should turn off.
Programming Test
The purpose of this test is to verify that the decoder correctly accepts programming commands.
1. Turn power to the system OFF.
2. Connect the red lead of the test LED to the decoder’s orange lead.
3. Connect the black lead of the test LED to the decoder’s gray lead. Make sure no other decoder leads are shorted
to any other leads.
4. If your DCC system requires the use of a programming track, disconnect the red and the black lead of the decoder
and reconnect to your system’s programming track outputs.
5. Turn on power to the system.
6. The DSD supports register, paged, and direct CV access modes. The mode you use will be entirely dependent
upon the DCC system you are using and you should refer to your owner’s manual for further information. Using
your system controller, reprogram CV1, decoder address, to an address other than 03 that is within the range of
your system’s capability. Write down the address that you select.
7. Turn off power to the system.
8. Reconnect the DSD’s red and black leads to your DCC system’s track outputs.
9. Turn on power to the system and reconfigure it to send commands to the address you programmed in step 5.
10.Now slowly increase the throttle. The Bipolar LED should now begin to glow. This indicates that the decoder has
accepted the address change. If the LED does not light, verify that the locomotive address is programmed to the
address you selected. If it still does not light, contact Throttle Up! For a replacement.
The Functional Decoder Test is complete. You have verified that your decoder is operating as it should and you can
now proceed to locomotive installation!
