1.1 Introduction
The TREK-550 is a dedicated box computer for industrial vehicle fleets, transport
trucks, buses and taxis. TREK-550 combined with variety of I/O connectors can be
connected to devices like OBD-II or TPMS (Tire Pressure Monitoring System). Dual
display/dual audio interfaces supporting different resolutions can deliver different
applications to different displays; eg: one application to a fleet driver and another to
a digital signage application.
Built-in wireless communications (WWAN, WLAN, BT) enable TREK-550 to send
important driver/vehicle/location/cargo information back to the control center.
TREK-550 can also operate in extreme environments with features like a wide
working temperature range (-30 to 70 degrees). TREK-550 also uses a special
design to handle the critical issue of in-vehicle power. Special power protection
(ISO7637-2/SAE J1455 Class A/ SAE J1113) and car power management software
(Ignition on/off, delay on/off, low battery monitor) prevent electrical noise and surges
from impacting the system, guarding against damage from transient car power.
TREK-550 also support rear view monitor through connecting video in port. With this
feature, driver can real time monitor the environment on two sides of the truck for
driving safety. TREK-550 can also support dead-reckoning feature, which means the
truck can still be traced even the driver is driving in a tunnel.
