5. Insert the device into its ‘host enclosure’ while maintaining device in close proximity
to the Mag-Plate. This isn’t critical, but it minimizes the possibility of inadvertent
activation.
Device Operation, Standard Firmware
1. It is assumed that the device is on the Mag-Plate and is in Dormant-Standby state.
Separate the device from the Mag-Plate by at least 6 inches. The device will
activate after approximately 5 seconds (time integration).
Upon activation, the VHF transmitter starts and continuously outputs signal; the
cellular module simultaneously powers up (as evidenced by the Green LED).
The VHF carrier frequency, RF power output level, and ASK modulation are fixed
and continuous.
The cellular module’s ‘activated’ sequence includes: CDMA/PCS network
registration, DNS look-up, and initial notification messaging to WT Server via UDP.
The device then enters a location loop which successively receives location-fix
updates and messages them to the WT Server.
If the cellular network is not available to the device, it will repeatedly attempt cellular
module restart/registration while it remains activated. The VHF transmission
continues independently.
2. After test completion, place the device back onto the Mag-Plate. De-activation will
commence after approximately 5 seconds, as evidenced by termination of the VHF
signal. The device will complete its current pass through the location loop, transmit
a shut-down message to WT Server, and secure the cellular module (Green LED
extinguishes). Thus, a return to Dormant-Standby state requires 30 to 60 seconds
for completion.
