5.2.9 Frequency Output (Option)
When the System is extended with the Frequency Output Board, the frequency output can
be set between 1Hz and 10MHz in steps of 1Hz using this function.
The input mode is explained in the description of the Frequency Output Board.

The output behaviour of the Frequency Board can be defined with
TimeON
and
TimeOFF
.
The
TimeON
timer defines how long the System has to run in synchronization status
"R"
be-
fore the output is enabled. This setting can be used to ensure that the base System is in a
precisely regulated state.
The
TimeOFF
timer can be used to define how long the transmission should continue alt-
hough the System has changed synchronization status from
"R"
to
"C"
.
Timer
Input values
TimeON
0…255min.
TimeOFF
2…255min.
This function is not available via the Remote-Interface (
hmc
) in RC-
Systems.
5.2.10 Status and Pulse Output
A programmable output is available on the internal connector (pin
8C
) which can be as-
signed with status message, cyclical pulse or DCF77 pulse (1 Hz).
The setting must not be changed by 1U devices;
otherwise the status
output of the status LEDs and error relays will be faulty. Set value for 1U
Systems = 0000 0001
Programming takes place by entering a byte. The input is selected with the following selec-
tion frame:
