VLB-67 V1.0.17
It is the effective intensity of the VLB-67 that is programmed. The peak intensity is controlled
automatically according to the flash character (Schmidt-Clausen correction) to maintain the
required effective intensity.

Synchronising Options
The synchronisation options available are as follows:
Product
Hard wired
GPS
VLB-67 Self Contained LED
beacon
Factory Option
Internal GPS option or
External GPS using Vega VSU-29 If sync
wire available on beacon
VLB-67 Stand Alone beacon
Yes
Internal GPS option or
External GPS using Vega VSU29 If sync
wire available on beacon
For Vega LED products the sync pulse has a positive to negative transition.
The sync pulse will occur at the start of the flash character. Where the lights connected are all
masters the first light to send a sync pulse will control the other lights.
Each light can be set to be a sync master or sync slave. As a slave the VLB-67 will not operate
unless receiving sync pulses, however the slave will still generate a sync pulse when operating.
In slave mode the VLB-67 will operate on the basis of the sync pulses received and will stop
operating after a programmed number of flash cycles after the sync pulse is lost.
Operation
=Program (or read)
=1 (or 9)
Feature
=Synchronisation
=3
Value
=XYY (999 disables synchronisation)
X determines if the light is a master or slave unit.
y
0YY
Master
y
1YY
Slave
YY allows for the start of the flash character to be delayed from 0.0 seconds to 9.9 seconds in
0.1second increments. For example YY=25 would provide a delay of 2.5 seconds.
Where an internal GPS unit is used the flash character will always synchronise to the GPS time
pulse. The GPS synchronisation will not be accurate until the GPS has acquired a valid time
signal. When using GPS Synchronising the VLB-67 must be set for Sync Master (0YY)
When an external GPS sync unit is used, such as the VSU-29, refer to the manual for this device.
5.5.1 Additional Sync Options
To program a slave VLB-67 beacon unit to keep running for a number of flash cycles after the loss
of the master sync pulse.
Operation
=Program (or read)
=1 (or 9)
Feature
=Flash count on Loss of Sync
=7
Value
=0YY where YY is the number of
flashes (999 = never stops flashing)
To program the VLB-67 beacon to use the sync wire to turn the beacon off when the sync wire is
grounded.
