Byteflight Master

The byteflight master has two tasks to perform:

• Generation of the synchronization pulses (Sync. Pulse)
• Setting the satellites in alarm mode (Alarm Pulse)

In the ISIS, the SIM is configured as byteflight  master (bus master). In principle, any satellite can be configured by software as bus master. However, there may only be one bus master in the system.

All other satellites (bus slaves) use the sync pulse for internal synchronization. Each slave can transmit telegrams between the sync. pulses on the byteflight.
