SL-PEL Series
Sectored Port Entry Light
FLASH CODE
In addition to being able to enter flash codes in the Flash Code Tab, flexibility is offered at the Advanced
Tab where individual LED flash codes may also be set for user customisation.
NOTE
: If a custom code has been selected (FFF), refer to the Flash Code tab for a description of the
character selected.
Flash Code settings for each individual LED may be entered in the Flash Code Column (as a
hexadecimal code). Enter the flash code for each LED and click ‘Write FC.’
Note: Although the PEL has the ability to use all and any character, the purpose of the light is for the
mariner to safely enter a port or pass through a difficult channel with restricted access. Accordingly the
marine will favour a character with a long viewing period with the light on i.e: Fixed, Occulting, Isophase,
or Long Flash. Since the mariner will generally be viewing the light against a port or town, a FIXED
character is generally not recommended as it is difficult to identify. Maintaining a flashing character also
saves power.
When selecting different characters for LEDS to provide a simulated oscillating boundary effect,
characters of the same total period should be selected. All characters with the same total period will
automatically synchronise.
For a list of flash codes, please refer to the ‘Flash Codes’ section of this manual.
SYNC OFFSET
The synchronisation offset is used to adjust the relative timing of the selected flash code for each of
the LEDs. When two LEDs have the same length flash code and the same sync offset, they will be
synchronised.
Since an observer can only see one LED at any one time or for a momentary period as they cross a
boundary it is unlikely that this facility will be utilised, but the flexibility is provided.
Writing LED Synchronisation
Sync Offset settings for each individual LED may be entered in the Sync Offset Column (in seconds, Max
Offset=5.1s). Enter the Sync Offset for each LED and click ‘Write Sync.’
