Custom character type 9YY.

5.2
Custom Flash Character.
When programmed the flash character code for the custom character is 999.
To program the custom character the details of the on and off periods of the flash character has to
be recorded.
The programming a custom character has its own Syntax and this needs to be followed correctly to
be able to program the character successfully.
Operation
=Custom Character
=2
Value
=Code for the character
The code is entered in a series of 3 digit values representing an on period or off period. Each 3-
digit value is a multiple of 0.05 seconds. The 3-digit code for a 1 second on or off period would be
020 (20 multiplied by 0.05 seconds is 1 second).
The following restrictions apply:
y
The minimum period that can be programmed is 0.1 second or the code of 002.
y
The maximum period that can be programmed is 12.75 seconds or the code of 255. For
longer periods than 12.75 seconds an ADD code can be entered
There are two special codes used as part of the custom character programming
y
The ADD code to get on or off periods greater than 12.75 seconds
= 001
y
The termination code when the programming of the custom character is finished = 000
Appendix C provides a work sheet, and an example, for programming a Custom Character
If an error occurs when entering a custom character the VLB-67 will flash the error code of 3 quick
flashes.
Programming a custom character creates a flash character with code 999. To get the VLB-67 to
use the custom character the value of 999 must be entered as the flash character.
5.3
Day/Night Use of the Light
The VLB-67 is capable of operation at night only or both day and night. The default setting when
the beacon is shipped is to operate at night only.
How the VLB-67 transitions from day to night mode and vice versa is determined by the
programmed day and night Lux levels. There are 12 different day/night transition light levels
allowing for a shorter or longer night.
Operation
=Program (or read)
=1 (or 9)
Feature
=Day/Night Control
=4
Value
=Select from Appendix A
=XYY
The first digit of the Day/Night Control value programs Day or Day/Night operation.
y
0YY
allows night time operation only
y
1YY
allows day and night operation
The YY digits of the Day/Night Control Value determine when the Day/Night transition occurs. The
Lux levels of the 12 settings are detailed in Appendix A. The accuracy of the light sensor is ±10%.
5.4
Intensity Settings
A different effective intensity can be programmed for both day and night operation. By having
different intensity settings the lights can be dimmed during the night. The programmable effective
intensity settings for the VLB-67 are provided in Appendix B.
