Programming the SW-9 Gold-JST/DSX decoder combo - Detail

The overview on programming CVs on one of the decoders using Programming on the programming track is here.

To program a CV on one of the decoders in the Gold-JST/DSX combo using Programming on the Mainline (POM) and without effecting the CV on the other decoder, using a Lenz LH100, follow these steps:

  1. Set both decoders to their short addresses. To do this set CV 29 to 2.
    1. Select the loco long address on the LH100
    2. Press F then 7 to select the POM menu
    3. Page using - to get the CV display, press Enter
    4. Select CV29 - enter 29, press Enter
    5. enter 2, press Enter to set CV29 to 2, which makes short address active in both decoders.
    6. Press Esc 3 times to get back to the Loco Display
  2. Select the decoder you want to program by pressing Cl, then entering 3 for the Gold-JST or 4 for the DSX, press Enter
  3. Test to be sure you have the correct decoder selected: blow the horn for the DSX, turn on lights for the Gold-JST
  4. Change a CV on the selected decoder
    1. Switch to POM mode (F 7 Enter)
    2. select the CV you want to change, enter the new value, and store it
      1. Enter, (CV number), Enter, (CV value), Enter
    3. Esc 3 times to get back to Loco Display
    4. Test the change
  5. repeat step 4 for any other CVs you want to change on this decoder
  6. When all changes are done and tested, switch to POM, set CV 29 to 38, and exit POM.
    1. Switch to POM mode (F 7 Enter)
    2. enter 29, press Enter
    3. enter 38, press Enter
    4. press ESC 3 times to return to Loco Display
  7. Repeat 2-5 if you need to change any CVs on the other decoder
  8. Set the other decoder bachk to Long address
    1. Switch to POM (F 7 Enter)
    2. enter 29, press Enter
    3. enter 38, press Enter
    4. press ESC 3 times to go to Loco Display
  9. Select the original long address and test all changes

This sounds complicated and tedius, but once you have done it a few times it is very quick and easy.

Example: Setting Volume on the DSX using the Lenz LH100 handheld on Loco #335 (my MEC)

  1. Select 335 on the handheld
  2. Press F then 7 Enter to go to the POM menu
  3. Page with the - key until the CV display is shown. Then press Enter
  4. Now enter the CV number 29 and press Enter
  5. enter 2 for CV 29, and press Enter
  6. Press Esc 3 times to get back to the original locomotive display.

At this point, both decoders have there short address active. 3 is the Gold-JST, and 4 is the DSX. We want to modify the DSX, so select 4 on your handheld. At this time, you should be able to operate sounds using address 4.

  1. Press F 7 Enter to get back to POM
  2. Go to CV 61, and change it to 103, which increases the ehaust volume slightly.
  3. Press Esc 3 times to go back to the loco display for address 4
  4. Increase the speed to test the volume (the loco won't move)
  5. If you aren't satisfied with the volume, repeat steps 1-4 until you are. Exhaust volume can be set from 96-111
  6. Press F 7 Enter to get back to POM
  7. Set CV 29 to 38 (to make the long address active again)

Now you have the CVs set for the DSX. You still need to make the long address active on the Gold-JST. To do this select address 3 on your handheld, and perform steps 6-7 above.

Select the original long address (road number) on you handheld, and test your changes.
