4.5 Master light mode
Any obstruction light can be set as a master of a light network. Only one light shall be the master in the
network. Master unit broadcasts time and illumination data to slave units via RS-485 / Modbus. Time is
typically received from GPS and illumination information comes from photocell
.
If the information flow from
the master unit to slave units is interrupted, the slave units will use local photocell setting and local time in
their operations. As the data flow resumes, the slaves automatically synchronise themselves with the master
unit.
Chain the lights as shown in section 3.2.5.
Set a lamp to master mode by switching its DIP7 on. Set DIP7 off in the slave lamps to put them to slave
mode.

Use configuration DIP switches 1-4 to give the slave lights RS-485 bus addresses. Duplicate addresses on
the same bus are not allowed. Give lights connected to the same communication bus an address starting
from one. RS-485 bus should be terminated with on-board 120 ohm resistors by turning on the termination
DIP switch on both ends of the communications bus.
In the master lights Web interface, configure:
► Data Tables -> Settings -> Slave Options
•
B0: Transmit Behavior Bits
► Data Tables -> Settings -> Slave behavior
•
B0: LI Red Twilight
•
B1: MI Red Twilight
•
B2: HI Red Twilight
•
B3: LI Flash (visible)
•
B4: LI Flash (IR)
► Data Tables -> Settings -> Options2:
•
B2: Do not use own photocell (will use default ToD, if no master connection)
•
B3: Use Default FPM if master connection lost
•
B6: Transmit FPM (Master mode only)
Then reset the lamps for the settings to take effect.
