Gossen Metrawatt DCF77 Radio Controlled Clock with Y Cable

The radio controlled clock is connected to the COM2 port at the summator with a COM1 / COM2 Y cable.

COM2 must be configured for use with the radio controlled clock.

Summator time is synchronized automatically as long as reception is good (always at xhxx:05).

Deviations < 1 second are corrected once per hour. An accuracy level of 1 second is obtained.

Switching to and from daylight savings and standard time is initiated by an H program (command: SUWI), because continuous reception is not assured, even with the radio controlled clock.

Time synchronization of several summators is controlled by the summator with the radio controlled clock.
