I am learning the KX-TDE as I go, and have a few questions re the software. First, I want to make sure that I can't accidentally do something that's going to leave me with an unworkable system. I believe that if I have a backup of all of the files on the SD card, then by copying all of those file back to the SD card I can get my system back to its original state at any time. Is that correct?
Are the license and activation files linked to the physical SD card, the EMPR board, or both? In other words if I take the SD card from system A and plug it into the EMPR card on system B, will it be operational, or are some of the files tied to a specific EMPR card? If I copied all of the files to a different SD card (say the SD card fails) would that card work (in the same system), or are some of the files linked to the specific serial number of the SD card?
is DKEYFR the only file (other than license files) that is tied to that specific system?
My immediate problem is that I have 2 KX-TDE600 systems, and one of them has firmware that's pretty new, (apparently newer than 6.0.1.1) and isn't compatible with my copy of Maintenance Console (7.4.1.0), so I can't connect to it. So, I either need to find a newer version of Maintenance Console or downgrade the firmware on that system to a version that I can connect to.
I'm thinking that I could downgrade the newer system by copying the files from the SD card of the older system to the SD card of the newer system (program files only, not license or activation files). I would leave LICxx files and DKEYFR intact. Would that work?
Is there a document that lists the differences between the various E600 firmware versions? I don't want to go the downgrade route if there are useful features in the newer firmware.
Probably enough questions for one post. Any help very much appreciated.
