How to Upgrade SEM Firmware

[schford]

Comfort is on latest 6x UCM Network again on latest 6x ..

New board is going in the attic so though I would be smart(hah) and upgrade it first :-)

Sticker on it says current firmware is SEM 5.139

Thought easiest way of doing it would be just to plug a 485 cable into it which I thought would give me 12v ov and the data bus.

Green light appears and then flashes.

I fire up Configurator go to modules then scan for new slave. - Get an error message \"Communication Error or Comfort or UCM Firmware does not support scan\"

Think to myself maybe as its such old firmware - so then I try to upgrade it from the UCM using the programmign cable but keep getting upgrade error.

So now am a bit stuck - anyone tell me how to do it?

Thanks

I tried removing the 485 cable to upgrade it - it didn\'t work but comfort did tell me slave one had lost communications.

I am really stumped now!

Incidentally I manually added Slave 1 to comfigurator and synced and now sem green light is solid.

yay all done I found http://www.comfortforums.com/view_topic.php?id=1782&forum_id=4&highlight=sem+upgrade

IS it worth making a link to it from the SEM firmware forum so no one else makes an idiot of themselves like I do :-)

You have just done the link!

To summarise, Slave and other modules with firmware less than version 6 need to be upgraded using the UCM programming cable, see http://www.comfortforums.com/view_topic.php?id=1782&forum_id=4&highlight=sem+upgrade

Once at version 6, the programming cable is not necessary, the modules can be upgraded using Comfogurator and UCM by Direct Connection if it is the UCM itself of By Comfort Bus see http://www.comfortforums.com/forum92/850.html
