I am running JMRI on an HP laptop connected to my PowerCab and SB5 via an NCE USB adapter.
I have set up all of my locomotives and can run them individually with no problems using the throttle in DecoderPro.
My problem is when I try to use the Consisting Tool.? I set up an advanced consist on my PowerCab with an address of 127 and the consist runs fine using the PowerCab as a throttle.? When I enter the same consist into the Consisting Tool and try to run it with the DecoderPro throttle everything works fine with the exception of the Horn functions.? As soon as I press the Horn or Short Horn buttons it kills the throttle.
Can anyone give me some suggestions as to why this is happening?
Thanks
Gary

Address 127?
Try address 70. (Anything under 100)
Odd and strange things with consist or short address between 100 and 127.

The JMRI Consisting Tool is not fully compatible with the Power Cab.

Set up your consists on your Power Cab according to the NCE consisting rules (see below). Then use a JMRI Throttle to select the Lead or Rear loco (never the consist address), just as you should with your Power Cab.

All will be well with the JMRI throttle - the routing of speed and function commands will be handled at the NCE command station level and JMRI doesn't need to know about the consist.

Since you are using an NCE system you need to read this document, which explains advanced consisting as handled by NCE systems:
<>

P.S. There is no problem with consist address 127 on any NCE system. There is a problem with consist address 100 on a Power Pro system. Valid consist addresses on various NCE systems are:
- Power Pro 1-127.
- Power Cab 112-127.
- SB3/5 112-127.

NCE philosophy is that you should always let the command station pick the consist address and that you never need to remember/use it. All subsequent operations (adding to, removing, breaking up) can be addressed to the lead or rear loco numbers, as should all speed, direction and function commands. Telling JMRI about the NCE consist address will lead to grief.

There is an NCE Edit Consist tool in JMRI. It used to work with the Power Pro, but my memory is that it got broken when a developer was trying to modify it to suit the Power Cab as well. I can't remember its current status. Better to use the Power/Pro Cab.

Thanks Dave Heap!
I am still trying to figure out this Consisting thing, and your discussion really does a good job of explaining it.

Hi Gary,
There was an issue, way back that I had, that when BEMF was on, it would cause that issue.
Hit horn & the engine would stop and restart the sound process.
Not likely anymore, but something that may be the issue.

That sounds like a decoder brand-specific problem. I have never experienced such problems or heard of it.

There are however some issues with the NCE Power Cab (and SB5) firmware that could conceivably cause problems:

1) If your Power Cab or SB5 firmware is not V1.65B (note the B) it is possible that Function Commands can be sent to the wrong Function when using consists.

2) There is an issue with the Power Cab firmware in that if you have been in Program Track mode during a session, there is a mixup of Horn/Bell keys until you unplug/replug the Power Cab. However, it won't be a problem when you are using the Power Cab in slave mode with an SB5.

Gary's problem may have also been caused by using the JMRI Consist Tool with NCE Systems.

The documents I suggested Gary read are the most accurate information available about NCE Consists. He needs to work through them. He also needs to avoid using JMRI consist tools with his hardware and just use a JMRI throttle addressed to the lead or rear loco address, just as he would/should with an NCE throttle. Trying to use the consist address or the Throttle buttons on the JMRI consist tools will interact badly with the NCE command station's implementation of consists, leading to frustration.

Hi Dave,
Yes, it was a Digitrax Sound decoder.
They fixed the problem.
But I threw that that out as an idea.
Sorry if that bothered you.
