GPS Synchronization
GPS synchronization is enabled when the MaxiHalo II controller is fit with an
internal GPS receiver and antenna.
A GPS synchronized light flashes in synchronization with the Coordinated
Universal Time (UTC) of Global Position Satellites. Thus, all GPS-equipped
Tideland flashers with the same flash code flash in unison without having
interconnected sync terminals or additional radio links.
A GPS configured Nova-65 SC can be synchronized with other standard ASCII
sync lanterns by connecting MaxiHalo II controller sync terminals. In this case,
the Nova-65 SC acts as the synchronization master, producing the ASCII
character to synchronize other lanterns. The light retains its remote monitoring
capability.
Optional Real Time Clock (RTC)
The RTC is an integrated circuit interconnected to the main microcontroller. It
keeps twenty-four hour time and date information. The RTC can be set and
read using SignalView. When main power is removed from the light, a lithium
battery maintains date and time. The primary function of the RTC is to program
the light to disable during the seasonal period when there is no vessel traffic,
and to re-enable during the season when vessel traffic is active.
RTC Battery
The RTC lithium battery is used for power when main power is disconnected
from the MaxiHalo II controller. S3-2 is provided to disconnect the lithium
battery from the circuit when the flasher is in storage. Before deployment when
desiring to use the RTC, S3-2 must be turned on.
LED Voltage Monitor
The LED Voltage Monitor measures LED array voltage, which is displayed in
SignalView. LED voltage varies from color to color and LED array to LED array.
Fail Terminal
The Fail Terminal (Figure 5 Fail Terminal Diagram), used to signal a failure to an
external device, is electrically switched to ground under normal operating
conditions. This is the default mode in a fail-safe system where either lack of
power or a failure asserts a fail condition. In event of failure or loss of power, the
terminal is open. Signal current is limited to twelve milliamperes. The default
logic can be reversed (open during normal operation, switched to ground during
failure) using SignalView to unse
lect “Invert Fail Output”.
