The KNX module follow the KNX specification and includes powerful mechanism to avoid collision and ensure that communication goes to the right node. LBT (Listen Before Talk) is handled automatically by the module in the way that the module goes into RX mode and check if the channel is free before transmitting data. In addition you install the serial number into the address register to filter out incoming packets not intended for this module. This ensures that the module only accept packets form units with correct serial number.
