MODEL 4380 MULTIBEACON
0014296_REV_B
Therefore at a 2 second interrogation rate, “H” = 39.7 hours of Transponder operation with an Omni
projector, BATS type reply pulse and Telemetry disabled.
For Transponder operation with Directional Projector:
(
eq.2
)
H hours = 30 Watt-Hours / (.0045 + 2.0/P)
Therefore at a 2 second interrogation rate “H” = 28.7 hours of Transponder operation with a Directional
projector, using BATS type reply pulse and Telemetry disabled.
For Responder operation with a directional projector:
(
eq.3
)
H hours = 30 Watt-Hours / (0.15 + 2.0/P)
Therefore at a 2 second interrogation rate “H” = 26.1 hours of Responder operation with a Directional
projector, using BATS type reply pulses and Telemetry disabled.
NOTES:
- Battery self-discharge is < 10% per month.
- Although the batteries used in the 4380 beacon are rated by the
manufacturer as having a nominal capacity of 2.4 A-Hrs, the charge circuit
is only charging them to 85% of capacity. This is deliberate, by sacrificing
15% battery capacity the cycle life of the batteries is significantly
increased.
- A discharged battery can be fully charged after a period of 5 hours when
the Beacon is externally powered by a 24v – 55v supply with a 1 amp
compliance.
- The 4380 contains two small Lithium ION batteries (<100 w-Hr)
therefore it is exempt from shipping restrictions as defined by IATA 967,
section II.

Configuring the Unit
The sub-sections below explain how to configure the unit.
3.1.2.1
Serial Port Operation
The 4380 series multi-beacons are equipped with a serial port connection that can be used to configure
the beacon. The serial port is available external to the beacon through the RS232 connection on the
