2.7. Start-Clock Mode
This mode enables MLED Display to be used as a fully configurable start clock.
Different layouts with traffic lights, count-down value and text, can be selected according to
the user defined selections.
External Jack inputs 1 & 2 control the start/stop and reset functions. Full control is also
possible from our iOS App.
Guide line for a proper countdown sequence setting:
** For reference: TOD = Time of Day
1. Select whether a manual countdown or automatic start at a defined TOD value is
required. If TOD is selected, countdown will start before TOD value in order to reach zero
at the selected TOD.
2. Set the number of countdown cycles. If more than one cycle, the interval between cycles
has also to be defined. For proper operation, the interval value must be greater than
the sum of the countdown value and the « End of countdown time ». A value of ‘0’
means infinite number of cycles.
3. Set the countdown value, initial color and color change threshold, as well as audible
beep if required.
4. Select the desired countdown layout (see description below).
5. According to the selected layout, all other relevant parameters should be configured.
Before countdown:
After initial power-up, the display enters a “wait for synchro” state. The default synchro is
defined in the settings. Other synchronization methods can be initiated via our IOS
Application. Once the synchro completed, the state changes to “wait for countdown”.
According the selected parameters, the Countdowns will either be started manually or
automatically at a predefined time of day.
During the “wait for countdown” state, a predefined message can be displayed on the upper
and lower lines as well as TOD.
During countdown:
Depending on the selected layout, information like countdown value, lights and text will be
displayed. Countdown value and traffic light color will changes according to the following
rules:
When the countdown starts, the main color is defined by the parameter « Countdown
Color ».
Up to 3 color sectors can be defined. When the countdown reaches the time defined in a
sector, the color changes according to the sector definition. Sector 3 has priority over
sector 2 which has priority over sector 1.
Countdown will stop at the value defined by the parameter « Countdown end time» its
value can be set from 0 to 30sec after countdown reaches 0.
When the countdown reach zero, a time frame is sent on the RS232 together with a
synchro pulse.
When the countdown end time is reached, the TOD is displayed until the next
countdown.
