Method of synchronizing a plurality of devices, wherein each of the plurality of devices operates in sync with an internal clock signal such that actions performed by each device are timed based on time cycles defined by a periodicity of the internal clock signal, the internal clock signal of at least one of the devices being periodic at a first frequency, wherein the plurality of devices is mutually synchronized via a party line to which all devices of the plurality of devices is connected; the method comprising: providing, from a system clock to each of the plurality of devices, a system clock signal which is periodic at a second frequency smaller than the first frequency, the second frequency thereby defining a plurality of sequential system clock cycles; synchronizing, in each of the plurality of devices, the internal clock signal based on the received system clock signal; and triggering, by at least one device of the plurality of devices and in sync with the system clock signal, a system synchronization event comprising: changing, by the at least one device during a first time cycle, a signal status of a common party line signal on the party line such as to signal the synchronization event; and monitoring, by each of the plurality of devices during a second time cycle, the common party line signal on the party line for registering the change in signal status of the common party line signal; wherein the second cycle occurs later than the first time cycle and is separated therefrom by one or more further time cycles, wherein a duration from a start of the first cycle to an end of the second cycle is less than a duration of one system clock cycle. providing, from a system clock to each of the plurality of devices, a system clock signal which is periodic at a second frequency smaller than the first frequency, the second frequency thereby defining a plurality of sequential system clock cycles; synchronizing, in each of the plurality of devices, the internal clock signal based on the received system clock signal; and triggering, by at least one device of the plurality of devices and in sync with the system clock signal, a system synchronization event comprising: changing, by the at least one device during a first time cycle, a signal status of a common party line signal on the party line such as to signal the synchronization event; and monitoring, by each of the plurality of devices during a second time cycle, the common party line signal on the party line for registering the change in signal status of the common party line signal; changing, by the at least one device during a first time cycle, a signal status of a common party line signal on the party line such as to signal the synchronization event; and monitoring, by each of the plurality of devices during a second time cycle, the common party line signal on the party line for registering the change in signal status of the common party line signal; wherein the second cycle occurs later than the first time cycle and is separated therefrom by one or more further time cycles, wherein a duration from a start of the first cycle to an end of the second cycle is less than a duration of one system clock cycle.
