Hi,
My work has a crestron cp2e unit that was installed around 2007. It was a rather large system with about 10 touch panels, three cp2e processors ( I assume in slave/master mode), a couple bipad8 units for audio control, a video switcher for three projectors in meeting rooms, and some other stuff. My boss consulted a reputable AV system company to install a new system for the meeting rooms with new projectors and HDMI support using quickmedia wall inputs. Well they claimed removing three touch panels and removing the processor associated with that floor wouldn't affect the rest of the system. Unfortunately after the install (their stuff works great) the rest of our system quit working, such as most all functions with our touch panels. On one of our processors on the second floor the error LED is flashing red. My question is, is it typical that removing three touch panels would cause a problem with the other units? Or could the system continue on without connecting to them/ finding them on the network. Also, if a slave was removed from the network, would the others continue to operate simply without whatever features were running off that slave?

I'm fairly technical and have done quit a bit of research on crestron units and how they communicate. But since I am not a dealer I cannot program them myself.

Any feedback is appreciated. Trying to save the company some money if its fixable without upgrading the other half.
Thanks

Does your company have the programs for all the processors? Without these programs there would be no way that this company that did the upgrades could know how the old system was running. If equipment stopped working after the upgrades I don't believe these processors were programmed as Master and Slaves instead programmed with intersystems. To save wiring a processor would have been installed on different floors/areas of the building and would communicate to each other over the network.

The error light could be a lot of different issues. However, if it wasn't on before the upgrades were completed I would guess that these systems were programmed as above using inter-system communication and now that one processor is missing an error will be reported as it has lost communication with the removed processor.

Again, without the actual programs (simpl files) there would be no way to know exactly what is going on.

Thanks for the reply. I wasn't there when the upgrade happened but from what I can tell I still have all three processors, two are still running and the one that was removed is offline. I could download the program off of each one...

Anyways, My other question is if it was in slave/master mode and a master couldnt connect to a slave, could the operations that are running on the other slaves that are still active run from the touchpads? Or if the system is missing a slave (or other component such as cnx-pad8) will the whole thing quit.
Just trying to see if i could do the fix myself ( if its not requiring reprogramming), to save $50k in upgrade costs.

Or if using intersystem comm, if one processor went down, would the other programs and other two processors still provide their services?

I managed to get crestron toolbox so i will be checking the error message tomorrow.

Also I went in and looked at the other devices.
3 - cnx-pad8a
3 - cp2e
1 - qm-md8x8
7- qmAE
1- qm-md4x2
8 - prodigy ptl4 touch screens
7 - QuickMedia connects throughout building.

You could but would be useless. Once the program is compiled, you can't work with it. Unfortunately, the other company that said you could remove it doesn't know what they're talking about.

Thanks for the response. If the program can't reach another device would the rest of the program and functions still work? ex, as in touchpad button presses to activate sound, etc.

update: I went in today and tested out the problems. I was able to get audio to play in some of the zones but wasnt able to get it to play in the most important two zones. For some reason, the tps-4l touchpad volume controls are sporadic and often slow. I also found that some devices have duplicate IDs ( A touchpad and a slave controller have ID of 0B, Two QM-AE have ID of 10), I suppose this is causing some problems... Would someone ever have two same IDs for any reason? Could that be causing slow response times? Or could the system just be old and slow...

I have a few jobs with multiple processors and some devices share the same ID BUT they're connected to separate processors/gateways so it doesn't matter. Did they have problems before?

With two devices having the same IDs it is looking more like each processor is running their own programs with intersystem communication to the other processors to access the programming of each other.

You would have to connect to each processor and look at the IP table as this will show you whether they are independent programs with EISC's by matching the IP ID's (masters/slaves) with the other processors.

-----------------------------------------------------------
I have connected to all two that are online. I have attached a screen shot of the slave processor. It looks to me that there is no ethernet communication devices on this and they're all communicating over cresnet typical Y Z wire. There is also no program listed as running on the slave ( which is correctly operating if thats the case). Would there be a way to see if the cresnet ID of each component is correct and matching one being used in the running program on the master (using toolbox)? I dont have the original smw file, just the compiled one that is running.

- Also found another touch panel that I did not know existed (CT-1550). It seems to show "Cresnet Error" sometimes when i'm trying to click things. Any advice on this? Could incorrect voltages be causing this?

Thanks for the support.
Tomorrow I am going to check if the installer put the smw file in the processor in the file manager. (If im lucky...)
