Bodet Sigma Mod - Option Board: 3 AFNOR Outputs

49
14.2 Option board with 3 AFNOR outputs
This option board does not require any software programming (by default the
time is the local time dened in the Sigma and the line is stopped). Only the
time zone differential and the state of the line (On / Off) is to be dened in the
“Time outputs” technician menu (see page 36).
Connect the clock lines on outputs A, B and C.
Each output allows up to 50 clocks to be synchronised over 30 km.
Remark: the 3 outputs supply the same time. To have time distribution lines
with different times, they must be programmed on different option boards.
If a short-circuit is detected on the line, an “AFNOR fault” error message is
displayed (if the programming permits) on the readout of the master clock.
If an AFNOR board occupies a slot, it takes the corresponding output numbers
(Slot number + 3 (3 corresponds to the rst 3 outputs already assigned)) with
a letter ABC. For example, if a board with 3 AFNOR outputs is placed in slot 1,
the outputs will be 4A, 4B and 4C (useful for alarm information).
Remark: in the “Time outputs” technician menu, “DEL” mode is used only to
uninstall an option board from the master clock.
