Many mobile applications require a small, rugged vehicle-mount computer for a variety of data entry and lookup, fare collections, decisionmaking, and other custom applications. Such computer must be simple to use and operate, ultra-reliable, and small enough to never get in the way. The QSI TREQ-L mobile data terminal was designed for such tasks, and it comes with a display that's significantly larger than those of handheld terminals.
The TREQ-L measures 7.9 x 6.3 x 1.5 inches and weighs 2.65 pounds in a typical configuration, still small enough to easily mount in any vehicle via standard RAM Mount hardware. The fairly large 7-inch touchscreen display with wide-format 800 x 480 pixel resolution. The display has an LED backlight. Operation is via touch or seven lighted, programmable function keys and a lighted 9-way cursor key.
The TREQ-L runs Windows CE 5.0 Core or Professional on the 416MHz version of the ubiquitous Marvell PXA270 processor that's been doing duty in millions of handhelds fo years. The device comes with 128MB of RAM and 2GB of non-volatile memory. The TREQ-L has two USB host ports, as well a serial port configurable as either RS232 or RS422. This being a vehicle-based terminal there is no battery; instead, the TREQ-L uses 8 to 32 Volt DC vehicle power (usually the 12 or 24-Volts that are available).
QSI designed the TREQ-L to withstand the type of handling and environmental conditions encountered in vehicle use. The device is rugged, with the housing made of a blended polycarbonate and polyester resin. It can operate within a very wide temperature range from -4 to 140 degrees Fahrenheit, which is probably more than a driver can handle. It is virtually immune to shock and vibration as well.
There is no integrated wireless connectivity here as the TREQ-L represents the low-cost offering of the platform (the TREQ-DX includes 10/100 Base-T LAN, 802.11g wireless Ethernet and a quad-band GSM/GPRS modem). The TREQ-L is mostly geared at tasks ranging from vehicle systems control and monitoring to Automatic Vehicle Location (AVL) and Computer Aided Dispatching (CAD) via 3rd party software and peripherals.
QSI began operations in 1983 as a manufacturer of low-power bus board computers. Today, the Salt Lake City, Utah based company designs and manufactures operator interface terminals for industrial, commercial and vehicle applications.
