Starting with Firmware Version V1.10 B05, the Q.station can now be hardware synchronized with a simple digital I/O pulse signal.
Before it was necessary to apply a sync protocol like Q.sync, IRIG or AFNOR for precise hardware synchronization – with the disadvantage of expensive sync sources.
With this new feature, multiple devices that provide a simple rectangle sync signal can precisely lead the hardware synchronization on the Q.station.
The Q.station needs to know the sync frequency (configuration option) with an adequate pulse applied to the digital input, and it will correct the internal clock accordingly.
