GRJ, I am interested in using the DZ2001 with my DZ2500 switch machines. Good idea or bad idea? I have read this entire post but want your opinion. If I do this I would take your advice put them in groups to make troubleshooting easier.
The DZ-2001 works fine with the DZ-2500 switch machines, that's what I'm currently using for mine.
Another question is does the CSM2, instead of the DZ-2001, solve or at least help this issue?
Actually, the CSM2 doesn't work properly with the DZ-2500, that's why I stopped using it and went with the DZ-2001!
I believe I've figured out what the issue is. Apparently either the CSM2 initializing it's serial outputs or the DZ-2500 seeing something it doesn't recognize on the serial data causes the issue. What happened to me is about every three or four times I'd power up the layout, all the DZ-2500 switch machines would be locked up solid! They didn't respond to local or serial data control. The best guess is that they were in manual control mode where you use them like a manual switch machine. I suspect that by simply delaying the power up of the DZ-2500's for a couple of seconds after the CSM2 boxes were powered up would solve it, but I haven't gotten around to changing things to do that. Since the DZ-2001 is working fine, I didn't see the urgency to change back to the CSM2 serial feeds.
