Error Relay - Meinberg LANTIME M300 Manual

5.3 Error Relay

On the back panel of the device you can find a DFK
connector labeled "Error". This relay output is con-
nected to the TTL TIME_SYNC output of the refer-
ence clock (GPS, PZF, TCR, ...). If the internal refer-
ence clock has been synchronized by its source (GPS,
DCF77 or IRIG) the relay will switch to mode "NO".
In case of bad antenna signal or the device has been
switched off the relay falls back to mode "NC".
