STM 940 firware upgrade

My main module failed. I have a backup model 940 STM AN.
After the swap I notied that the backup module does not support merkers as it has an old firmware.
Does any-one knows if it is possible to upgrade the firmware of the STM module and where to find the firmware?
Looks like I need version v1.76

thanks! 

Hi,

I mean it was never possible to change firmware on 940 Series

Hello,

As far as i know it's not possible to upgrade the firmware on an 940 STM AN.
I might have the right one on stock, you also might upgrade to an 941 STM AN with the right firmware.
If you want you can sent me an email, info@rodenburg-projectleiding.nl

Hi Nijn02, there was never a 940 STM without a marker.
Furthermore, the firmware in the STM 940 cannot be updated.

you can only update the firmware if you change the built-in eprom. Many years ago I upgraded my controls to the new firmware. I have some used ones in stock
