CSM2 and SER2?

The DZ-2001 works fine with the CSM2 boxes.  In truth, trying to use the serial data out of the CSM2 with the DZ-2500 is problematic, that's how I was first wired.  Every three or four times I powered up the layout, all the DZ-2500 switch machines would be frozen, no operation in command, and now even pushing the button on the switch machine!  If the switch machines didn't lock up, then all was well for that operating session until another complete power cycle.

I went back to using the DZ-2001 for all the serial data and the CSM2 for sensing, no sweat, and no more lockups.

I'm pretty sure I know what is happening and how to fix it, but I haven't gotten around to it.  I believe delaying the power up of the DZ-2500's for a couple of seconds to allow the CSM2 boxes to get their mind right will allow me to use that serial data.  However, since the DZ-20001 is working fine with them, it's not a priority.

Remind me, what is the purpose of the CMS2?

John, In your setup I am assuming you not connecting the blue wire to the CMS2, and using the dz2001 white wire to all the all the dz2500 blue wires. When you use the LCS app on the iPad can you change a switch direction on the layout screen?

Yep, the serial data doesn't have any direct connection to that operation, the CSM2 just monitors the switch position feedback and shows that.

To elicit silly questions like this!

OK, the CSM2 is the link from the DZ-2500 switch machine position indication and the LCS display on the iPad.  It shows you the actual position of the switch machine no matter what caused it to switch, TMCC, push-button, non-derailing, etc.

John, I must have something hooked up incorrectly. If a  switch is triggered by hand it doesn’t show any change on the ipad. I have the CMS2 wired with the blue data wire hooked up. I am also experiencing the same trouble with the switches not always working when I power up.

John, I think you have it right! When I read one of these threads on the CSM2 I am so glad I used ASC2's plus STM2's plus an auxiliary relay and power supply for my DZ2500 turnouts. They work first time, every time and all the iPads always show the current, correct positions.

Uh, given your own confusion and wasted time using this device, maybe it's not such a silly question.

I was always taught (and have taught myself) that the only really stupid question is the one not asked.

I'm guessing it's pretty dark where your head is.

George, it was a joke.  I hope you're not humor impaired.

Try the DZ-2001, I suspect that will fix the switches not working on power-up.  I know it was the "silver bullet" for me.

Thanks for the advice, I really appreciate it.  I am hooking up the dz2001 now.  John

Mine has worked flawlessly since I stopped using the serial data out of the CSM2 boxes.  Someday I plan on doing the power sequencing trick and trying the CSM2 serial data again, then I could eliminate one extra piece in the picture.

I'm not, you just caught me at a bad moment.  Sorry.

Seriously, what have you learned about this device?

George

The only thing that jumps out is the fact that the CSM2 needs time to initialize the serial data.  Obviously, before it is fully powered up and initialized, something comes out the serial port that the DZ-2500 doesn't like.  I don't know what "mode" the DZ-2500 is in at that point, but it's DEAD with the lights on, but no response to any outside signals.  Since that doesn't happen with the DZ-2001, I have to believe it's something coming out of the CSM2 before the microprocessor is initialized.

@gunrunnerjohn

Thanks John! You really are a wealth of information and I really appreciate that your share your knowledge with the fourm!

Again, thanks very much John!

John, When a DZ2500 switch is changed due to a derail or by hand does your LCS app update the switch position? Mine does not. I can change switch positions on the app and everything works fine, but if the switch is tripped bay a derail function there is no update on the app.
