Summary
[edit]| Description |
English: MDT AKS-1216.03 operator panel board
You'd expect there to be another MCU on this board, but no, it's actually all dumb logic, all LEDs and switches are accessed through 74'595 and 75'165 shift registers. The membrane keyboard turns out to not be a membrane keyboard at all, instead it's membrane buttons under a foil. This might be driven by a requirement to maintain class II isolation of the KNX bus? |
