Problems with the Set Position at a EKS36 / EKM36, in combination with the PGT-11-S, with STM32 controller

Why does the Set Position not work at a EKS36 / EKM36 at the PGT-11-S if the device uses the new STM32 controller?

EKS36 / EKM36 with a date code "jjww xxxxx" and later are using a new µ-controller. We changed from the ST08 to the STM32.
With this µ-controller change, we also had to write a new firmware for this encoder.

Due to security law, we had tho change the password management of the encoder.
The passwords 0 .. 4 are unchanged → this means, no change for the customer.

But there is a change in the higher password levels (5 .. 7).

At the start up, the PGT-11-S tries to enter the access level "7" in the encoder.
This is basically working at all current Hiperface DSL encoders.

But at the new EKS36 / ELM36 with STM32 controller (starting from date code "jjww xxxxx" and later) there is a difference.
The PGT-11-S can not enter the access level "7". And it stays in the access level "0".

The main problem is, that the "Set Position" is no more working, because this command requires the access level "4".

The user has to enter the access level "4" in the encoder manually.

The following video describes, how this is done.
