Chapter 1 General Information
1.1 Introduction
TREK-775/TREK-776 is fanless and is supplied with either Intel ULV
Celeron® M or LV Pentium® M CPU for higher reliability and perfor-
mance. The ruggedized aluminum enclosure is built without ventilation
holes and makes TREK-775/TREK-776 waterproof and dust proof.
A power source with wide input range suits vehicles such as forklifts and
trucks, which typically operate with 12 V, 24 V, or 48 V DC power.
When equipped with an adapter, it can operate with AC power. TREK-
775/TREK-776 provides 10/100Base-T Ethernet, and expansion options
for wireless transmissions such as 802.11b/g, GPS, GSM and GPRS, etc.
Embedded OS support (WinCE.NET, WinXP Embedded), using OS
images can greatly shorten system development and trouble-shooting.
