1.1 Introduction
The TREK-520 is a dedicated box computer for industrial, transport trucks,
buses and taxis. TREK-520 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 driver and
another to a digital signage application.
Built-in wireless communications (WWAN, WLAN, BT) enable TREK-520 to
send important driver/ location/cargo information back to the control center.
TREK-520 can also operate in extreme environments with features like a
wide working temperature range (-30 to 70 degrees). TREK-520 also uses a
special design to handle the critical issue of in power. Special power
protection (ISO7637-2/SAE J1455 Class A/ SAE J1113) and 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 power. TREK-520 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-520 can also support dead-reckoning feature, which means the truck
can still be traced even the driver is driving in a tunnel.
