I have a client that has a 2 RF processor system installed around 2002 and has been running flawlessly (house is about 6,000 sq feet). I provided some minor programming changes in the 10/2013 time frame and they were fine. System is maintained using HomeWorks 5.4903
On Friday I went over to do a few minor programming changes and during the upload, "proc2.dat" failed to transfer to the processor. I had to power cycle the processors to get the system back online (luckily nothing transferred so it still had the original upload).
I "know" the processor(s) are OK since all of the loads/programming function properly and the during the upload, the OS rev check passed for both processors. I powered cycled the processors, rebooted my laptop, restarted HomeWorks, changed upload ports, tried different baud rates, etc...no luck.
I called into Tech Support and after going through the list of stuff I tried, the tech support guy noticed that the latest version of HomeWorks is 5.4905 and the release notes have an entry about a change that went in to 5.4904 about an issue concerning uploads via rs232 and suggested that I retry the upload using 5.4905.
While that does make sense, I am worried that if the upload failure is "something else", I could get a failure uploading the new firmware and/or the new project would fail to load, rendering the processor(s) unusable to the point that I would have to replace them with a P5 processor (Illumination) which is a conversation I really don't want to have with my client.
Anyone have any words of wisdom here?
thanks
