MICROCONTROLLER BOARD (POWER SUPPLY)
Section 7: Control Inputs
Each input is active when the input terminal is connected to the negative of the
supply input (Common).
Input/Output
Sync Input
Synchronizes both White Strobe and Red Beacon.
When held steady (connected to Common) the Red
Beacon burns constant, and the White Strobe flashes
at 40FPM. To synchronize the white and preset red
flash rate, a 1 PPM signal may be provided.
Alternately, a synchronization pulse may be applied at
every flash to alter the flash rate. In both modes, the
synchronization signal must be asserted for at least
0.1s to ensure that it is properly detected.
Sync Output
Independent synchronization signal which may be
connected to the Sync input of other supplies when
multiple synchronized lights are required (leave all
other Sync Outputs unconnected)
In Day mode Sync output defaults to 40FPM
In Night mode Sync output defaults to 30FPM
