The 8-Digit Display and the LEDs

The 8-digit display generally displays the time information of the generated LTC as "hours
minutes seconds frames". With the operating mode "time E" (E key) one frame will be added
to the generated value. Pressing the set key or menu key the display switches to display
special data or text, pressing the enter key the status of the unit will be displayed (see chapter
"After power-on").
Whenever data are written into the non-volatile memory - by using the keys of this unit or via
commands from a connected MTD user console -, the display will indicate "Store" for a
moment. This indication will not disturb any current operation.
LED Function
menu Lights up while a menu line is displayed.
select Lights up while the start value or the trigger time (GPI) is displayed.
Goes out after pressing the set key.
Flashes if G30TTT does not generate the LTC(MTD), in that case the user bits are
used for example as date instead of transferring data for the MTD system.
free Lights up if the DCF77 or GPS receiver is not synchronised or not connected or not
built in. Will remain extinguished if the DCF77 or GPS receiver is synchronous to
the antenna signal.
mod. Flashes in the rhythm of data reception of a DCF77 or GPS receiver (once each
second).
field Only with built-in DCF77 receiver: indicates the field strength of the antenna
signal.
V4 Flashes if colour framing (cf key) has been activated, but can not be executed (e.g.
if no video is connected or the E key has been pressed). Lights up if the LTC is
locked according to the 4-field sequence. The 4-field sequence is derived from the
video signal or from the black burst at BNC Video In.
V8 Lights up if the LTC is locked according to the 8-field sequence. The 8-field
sequence is derived using the white flag at line 7 of the video or black burst signal.
jam Lights up as long as an LTC can be read, irrespective of the ltc key.
video Lights up if the LTC is locked to the video (connect video or black burst at BNC
Video In).
