Data synchronisation between PC and MDU

Data synchronisation is required when terminals need to be programmed but the MDU does not contain any data.

1. Switch on the MDU.
2. Start from the main menu (press the Home button).
3. Navigate to ‘Terminal functions’ > ‘Configuration’.
4. Is ‘Serial commissioning’ available in this menu?
   1. If this item is missing, no terminal data is available.

1. Log in to the Personnel Software and open ‘Extras’ > ‘Dialock Service Software’.
2. Connect the MDU to the PC while it is switched on. There are two options here (please use the method that applies to your system/that you are familiar with):
   1. USB (for ES100 mini or Pyramid; ES100): Connect the MDU to the PC via USB.
   2. Infrared (only possible with ES100 coding station): Hold/place the MDU in front of the lower side (Häfele logo) of the coding station.
3. In the Dialock Service Software, click on ‘MDU’ at the top and then on ‘Data synchronisation between PC and MDU’. (Note: The date/time should be synchronised; MDU data may be overwritten.)
4. In the window that has just opened, select the required rooms or all rooms and confirm with the green tick.
5. Wait for the transfer to complete.
6. (For USB: Remove the MDU from the PC.)

If the MDU is connected via USB but cannot be detected, follow the instructions in this article:
