The QTerm-G55 is a rugged, lightweight, handheld graphic operator interface terminal that is the latest in the vendor’s line of Qlarity terminals.
The QTerm-G55 can be equipped with two EIA-232, -422, or -485 serial ports; and an Ethernet 10Base-T or a Power-over-Ethernet (IEEE 802.3af) interface. The unit has a 320x240 pixel, grayscale, graphic LCD display. Other industrial-grade features include 24-key or 40-key membrane/steel snap dome keypad with LEDs; 2 Mbytes flash/16 Mbytes SDRAM; programmable speaker and real-time clock. The QTerm-G55 uses the vendor’s Qlarity object-based graphic terminal programming language that allows design of a simple control panel interface or a complete stand-alone application. The ability to use pre-defined objects, edit existing objects or author original objects provides flexibility for both novice and expert users, the vendor says.
