Hello
I'm new to the list and the JMRI Decoder Pro program. I've installed Ver. 1 on a Win98 machine and I have inconsistant results with my easyDCC. When trying to read values from a Digitrax DH121, DN121 or Soundtrax LC100 it returns all 0s or times out reading each CV. A Lenz LE103XF works like a champ, the neatest thing I've ever seen. I would also like to install Decoder Pro on a Linux machine but I'm not Linux smart enough to do it without an RPM. Does any one have any ideas about the easyDCC interface? Thanks Stony |
I'm new to the list and the JMRI Decoder Pro program. I've installedIt's just a guess, but could you check the "mode" setting on the programmer? There's one on the screen where you select the decoder, and then another one at the bottom of the main programming screen. I usually use "paged mode" for Digitrax decoders. Since the Lenz decoder works fine, the various connections, speeds, etc are probably fine. So I suspect that there's something about the mode selected in the programming commands. I would also like to install Decoder Pro on a Linux machine but I'mI'd be happy to help anybody who wanted to create an RPM for Linux, but don't even know where to start. Hopefully somebody will volunteer to educate me... Bob -- -------------- Bob Jacobsen (Bob_Jacobsen@..., 510-486-7355, fax 510-495-2957) At CERN until August 10, replies may be slow. |

You may need to install a resistor between the CS and the programming track.

The comment from CVP was: A reading of all 0's means there is excess amount of current consumed ' by the loco being programmed. The CS can't distinguish the motor pulse from the idle current. Before moving to the programming track, turn off all lamps and mute the loco sound. If still unable to "read" then insert a series resistance as shown in the manual for MRC decoders. This may desensitize the programming track circuit so the motor pulse can be seen above the idle current. But this will be a trial and error determination of the value - try 75 ohms to start. I think I have a 100 ohm resistor in place now. I did not find that turning off the lights/etc before programming made any difference. Mike On Saturday 03 August 2002 11:13 pm, buchcty wrote:

Thanks for the tip. An 82 ohm resistor and it works great. Stony ----- Original Message -----

I may have spoken too soon. The 82 ohm resistor cured my problem with SoundTraxx decoders but I still can't read values from Digitrax decoders. I've tried resistors from 68 to 150 ohms with no luck on DH121s and DN121s. Any other ideas. Thanks Stony ----- Original Message -----

My 'vast' experience includes programming 2 SoundTraxx DSD-150 decoders so I can't offer expert advice. You may want to contact CVP and run this problem by them. There is no risk of damage with a resistor that is too large or too small so I would try a bit larger range. It may be the case, that some decoders need resistors and some do not. You may also want to verify that the operations work directly from the CS (wispering: since there could be a bug in DecoderPro, but don't tell Bob I said this). cheers, Mike On Monday 05 August 2002 07:20 pm, Rick C.
