Short Description

This device is a Codelock with KNX connection which can send KNX telegrams on inserting codes/commands.

It also has some direct outputs to control a automatic lock (Like Abus CFA1000 or similiar).

There is a Keypad for inserting the codes, a piezo speaker for signaling key press and correct/wrong codes, a interface to a Motorlock remote controll (with 3,3V supply).

It fits into a case 40x80x20 (Hammond 1551KTBU) and can be placed in a "Elektronik-Unterputzdose".

  • FW V1.00 (supports Piezo sound transducer) Link
  • FW V1.01 (supports Piezo buzzer) Link

I plan to update the FW as soon there is a Konnekting Device Library V1.0.0 released, supporting FOTB - Firmware Over The Bus


There will no be a Layout or even PVB. The PCB is very simple, you can build it with a bread board (Lochrasterplatine). Have a look here for help.
