Tim,
I had this issue prior so I printed out the pages of the manual so I could follow them carefully. I hope I don't lose my "guy card" for reading the instructions like that. When I bought the RailPro system, I used a CI-1 to load sounds because that was the first thing I had. When I received my HC-2, I ran into this problem but the engines worked fine and did not investigate. When Jeff first got his LM-3s units, we had a similar problem and used the CI-1 to load sounds. Last weekend I went down with the instructions I printed out and was able to download from the computer to the handheld. Jeff brought his Hand Held and engines tonight and we ran into the connection problem trying to get the sounds on the handheld. The engine already had the sound because I had loaded it last week with the CI-1. Because I have been doing this on a Digitrax layout that has JMRI on it, tomorrow I am going to set up a small test track and power it with an MRC power pack to get just DC and try again. This way, I will not have the JMRI interface started on the computer at all, perhaps they cause the driver issue. Tonight I did a computer restart but did not do a full off and restart. Perhaps that left some residual glitch in place.
Beyond this issue, the RailPro engine worked well, did all of the switching chores required, I had good reception and was able to operated the locomotive while moving around. There were both RailPro and DCC engines operating across the layout all evening.
Additional notes: We both noticed on different units that the battery charge indication does not update after charging unless you reset the HC-2. Then it show a full charge. This is not an issue for us, just a note.
I had an issue loading sounds from the HC-2 to the engine. I moved another engine that was right next to the unit being updated and the problem went away. There may have been other factors however it seems having an isolated download track cannot be wrong. I have two units with RailPro installed and another on the workbench, Jeff has three also so the system will be pushed a bit. Are you aware of any limitation to the number of RailPro engines that can be operated at the same time?
Thanks for your input, I will update tomorrow after I do the test track.
