I have a pmc2+ locking up on every other upload. The error reads upload not completed. I have to power cycle and initialize the processor in order for it to load again. All the firmware is up to date. Anyone having the same problems with this processor. What a PITA !!!

Check the file size of the program... I had the same thing happen to me with an AMS to only find out that the program size was too large for the processor to handle.

It's a small system. 2- PTX3's which load to the remotes and 1 xpanel for mac controlling the 6- PDIMEX's and 2 Thermostats only

Are you using SB or toolbox to load the program? Toolbox is usually a good alternative when SB doesn't work.

I've been using SB. Tried to upload remotely earlier this evening. It locked on me again and lost communication to the processor. Will have to power cycle it again in the morning and re-load.....

Haven't had that problem at all.

I've had it randomly. Only a couple of times, never a repeated consistent problem. Now a shitty PTX3, different story all together.

There's not much info here to try to diagnose the problem. Usually you will see an X-Modem Aborting Upload type of message when the upload fails. Are you seeing this message when you try to load via Toolbox or just when loading via SB? Have you initialized the processor and then reloaded the processor? Are you loading USB or Ethernet to load? Do you get the same behavior when you load via USB and/or Ethernet? In other words, does it fail both ways of loading. What version of firmware? Latest is not a firmware version, nor is "up to date". How large is the compiled project? Have you tried renaming your project and loading that after compile? Does loading fail even when you load a blank program?

Sometimes you can create "digital junk" in the memory if you load the processor over and over again. I've seen weird behavior that I couldn't explain that was fixed simply by initializing the processor and re-flashing the firmware. In your case it is probably an issue with the compiled file. If you are having an issue like this with a piece of equipment you know it is not intended behavior. The best solution is to break the box down to factory state and start over. Every Crestron programmer will run into strangeness from time to time but it is generally rare and can be fixed by doing what I have suggested. I have read many of your posts here and would highly suggest that you partner up with a CAIP and have them help you with any system design questions as well as have them do your programming. (I would be happy to discuss the benefits of using a CAIP via PM with you, as well as pricing structures) Crestron can be a frustrating product to deal with because it is so alien to what A/V guys have dealt with for years. By the time you get to a Crestron solution you have likely been doing large RTI/URC systems for years. Since Crestron is nothing like RTI/URC/C4 in the programming department it can be frustrating as hell. Add a glitch into the project and it can feel like a nightmare. The good news is that it is actually very reliable product and once dealers become confident in the product the frustration goes away.

Today was the first time I tried loading via toolbox and no issues. I took the router out of the equation and loaded ethernet through the switch to see if the problem was with the router. No issues. On my last upload of the day ( with the router in the mix again) it began to fail again. Go figure!


Yes, I have to power cycle and re-initalized the processor. This is generally the only way to get the processor to load again. I did not re-flash the firmware though. USB loads fine. It's ethernet that is giving me problems. Internal memory usage is 1411kb. Renamed the project 3 times. Firmware version is 4.003.0015

Interesting. What kind of router? This is looking less like a program issue and more like an Ethernet issue, specifically the router doing something with the ports between you and the processor.


Try the firmware flash and see if the problems go away. Look through the router setup and make sure nothing is interferring with communication on ports 41794 and 41795 (TCP and UPD). Since USB loads without issue it is not a compiled file problem so we know the program is good and the processor is good everywhere but possibly Ethernet. I know there are some Ethernet issues with that version of firmware across all processors. You may want to roll back to 4.001.1027 if you can. If you have an iPad/iPhone/iPod in the project it can be rolled back but it will change the underlying code quite a bit and remove the native symbols for the Crestron Mobile interface. Not a big deal but that will mean no direct load to the iPad with the project and requiring the 2 ports for the iPad/iPhone/iPod project. I hope that makes sense. I have had some Ethernet issues with that firmware version and have been using a beta firmware to avoid problems. So far so good with the beta firmware.

I have an issue with my laptop when attempting to load wirelessly. Upload ALWAYS fails. Always works perfectly when wired. Other laptops work fine over wi-fi on site or over the internet. My issue is isolated to my computer.

Another/separate issue...

With a single zone prodigy system (simple theater) i get an error every time i upload. I don't remember what it is but its meaningless. The upload is always successful. If i had to guess i would say its from the remote not booting fast enough and System Builder not being able to get data from it so it spits out an error. I quit paying attention to the error so i don't know what it says exactly. Mentioning this because you might be seeing the same thing.

The router is a Linksys E3200. I also went as far as to turn off the UPNP in case the router was seeing the uploads as some sort of attack. No change


I did the firmware again on the processor and still had the same issues. I do believe it is a network issue but unable to pin down exactly where the problem lies.

Stamp - I recently read of a Crestron iPad wireless issue that was fixed with the disabling of the WMM feature of the router - Wireless Multimedia, tab under 'wireless settings' in the Linksys config browser setup page.

Probably not it, but worth a shot, for wifi troubleshooting.

I will see if I can bend the ear of a few internal tech people I know very well concerning that router.

So you downgraded firmware and still have the problem? If that is the case I am going to go out on a limb and tell you it is for certain a network/PC issue. Since you have not had this problem on other PMC2+ processors there is still a slim chance it actually is the processor itself but I would bet that it is 99.9995% a network issue. Managed switch(es) in the project? What does the network architecture look like?

You mentioned that it fails on remote loads and when the router is in place. No fails when you are just in a switch only environment. What firewall/anti-virus/spyware programs are you using and have you exempted all Crestron software? I remember an anti-virus issue a few years back but I cannot remember the name of the anti-virus software to save my life. If I were to see/hear it I would know that it was the one. That guy had to remove the software completely to get any Crestron software to work. Most programmers I know use AVG (free or paid) without any issues. It's what I use in my laptop for Win7Pro and the XP SP3 virtual machine.

One thing you may want to try, especially if you are on a Gigabit switch, is to set auto negotiation to off and then set the processor to 100/Full. If you still have problems set the processor to 10/Half. If you have problems past that and happen to have a spare processor you might wish to try a swap out. It could be the processor has some quirk in the Ethernet card. It would be great if you could swap processors for a test as we can then rule out, or in, the processor as an issue.

I haven't been back to test the downgraded firmware. No managed switches. Just standard Liksys 5 port 10/100 switches. Here is how the network is laid out.
