I'm a synchronized clock manufacturer, it appears Rauland has left some of their customers dissatisfied. Do you have any information for the serial stream fed to secondary clocks?

The old Rauland system 21 master clock would update their digital wall clocks with a serial communication after a power outage to bring the secondary clocks back to the correct time.

The new Rauland Telecenter U does not output that serial communication.

Does anyone know of a device that can output that serial communication?
