Background:
- This layout is all TMCC - no Legacy.
- I recently replaced 5 flaky DZ-2500A switch machines with new DZ-2500C machines.
- These are located in my lower level hidden storage yard (naturally
). Switches are supposed to work via both CAB-1 and pushbutton (DZ-2502P). - The switches were all reprogrammed off the layout using a spare Command Base, 15 VAC tap from a K-Line PowerChief 120F transformer, and a brand new DZ-2001 Data Wire Driver. All programming went well and these switches (numbered 17-21) throw correctly via CAB-1. At the time, they were not tested using the pushbutton.
The Problem:
- I installed Switch No. 17 back onto the layout and added power. It would not throw using the CAB-1 remote but would operate via pushbutton (DZ-2502P). Some other switches (DZ-2500A's) that had been working for years would also not work via CAB-1. Some would. Pushbuttons seemed OK. After cycling the power and trying this again several times, all functionality returned to all switches (including the new No. 17).
- Feeling like the gremlins had been banished, I then installed Switch No. 18 back on the layout and added power. Same behavior. Works using pushbutton but not via CAB-1. All other switches (including No. 17) work fine both ways. This has still not resolved itself.
I've shot an e-mail off to Dennis Zander, but I would very much appreciate any thoughts on this bizarre behavior. Help!
Thanks,
George
