The power input, ground and GPIO signals that are present on the main 8 pin external
vehicle connector are also available on the 8 pin internal expansion connector. On the
internal connector, there is also a unique battery supply pin that supports connection of a
rechargeable battery.
Over The Air (OTA) program updates are supported through Firmware Over The Air
(FOTA) protocol. This server based update system is licensed from HP.
All inputs are electrically hardened against overvoltage and over current conditions
present in automotive environments. This includes transient electrical noise and Electro
Static Discharge (ESD). The power input is further protected against over current with
an internal, self resetting fuse.
The Arrow enclosure and its features are secured using M2 sized metal fasteners for
rugged mechanical performance. The daughter board expansion and vehicle interface are
achieve through robust, commercial grade, pin to wire header connections (in contrast
with leaf contacts commonly used in cell phones and other portable non-industrial
systems).
The Arrow is physically disguised to appear to an untrained observer to be a nondescript
part of the cabling system. It is a small black box with unremarkable features. Two LED
status indicators are provided to verify correct installation and initial operation. A unique
feature extinguishes those status indicators 24 hours after an initial power up sequence.
This feature further conceals the ion Tracker from untrained parties wishing to defeat its
operation. The status indicators resume normal operation after the primary power has
been removed for any length of time. This allows for maintenance to be initiated by
simply disconnecting and then reconnecting power. This feature may be disabled as a
factory option.
The Arrow Tracker uses a simple cabling arrangement and supports splicing into an
OBDII extension for power. Connection to the vehicle is made through a 3mm pitch
rectangular header connection common to the automotive market.
As with all GPS location devices, the ion should be installed in a vehicle such that it has
an unobstructed view of the sky during normal operation. Double sided foam tape can be
used to secure the surface not facing the sky if needed.
