In this technical walkthrough, we take a focused look at the KM50014542G11 elevator shaft communication board from SULAB. You'll see how this critical PCB board functions as the communication hub within elevator shafts, collecting floor signals, managing bus communication between floors and the main board, and ensuring safety interlocks are properly maintained.
