The ASK performs the role of network master for the MOST bus. The functions of the network master are the following:
- Wake-up, initialization, power-down - The network master wakes up the bus and has the task of achieving an orderly initialization of the network. The ASK can operate with KLR off. To turn it on, push in the volume/ON/OFF knob. Adjustments and control is carried out by using the Controller and Control Display. Another task of the network master is to control the power-down process. Each power-down is initiated and started by the ASK.
- Configuration control - The network master detects the exact system configuration each time that the network is started and compares it to the stored coded configuration.
- Control of the network operation - The network master controls the MOST transceiver of the slave equipment for correct operation. The equipment which is not operating properly will be released by a reset or switched to low power mode so that they do not affect bus communication.
- Fault code memory - The network master includes the fault code memory of the MOST network. It stores all the faults occurring during the network operation as well as deviations from the nominal configuration.
