Qlarity-Based Terminal Hardware 1
CHAPTER 1
QTERM-G70 TERMINAL
1.1 Product Description
The QTERM®-G70 terminal is an Ethernet-enabled graphic terminal with object-based pro-
gramming. It features a robust list of industrial grade hardware features and options.
The QTERM-G70 features a QVGA, 320x240 pixel, LCD display available in STN color (256
colors) or optional grayscale (16 shades) or active-matrix TFT (256 colors). It uses a
cold-cathode fluorescent backlight (CCFL). The CCFL provides high contrast and easy read-
ability and is replaceable. On STN and grayscale units, the contrast is software-controlled and
compensated for temperature.
The analog-resistive touch screen covers the full viewable area of the display as well as the
pre-labeled legend underlay on each side of the display.
The QTERM-G70 comes equipped with one serial port using an EIA-232, EIA-422, or
EIA-485 interface. A second serial port, an Ethernet port, and a PS/2 keyboard port are avail-
able as options.
Possible input devices include the touch screen and attachable keyboard (with an optional PS/2
connector). Custom configurations of the QTERM-G70 can also support an external keypad, a
dual EIA-232 full serial port card or a quad EIA-232 full serial port card (contact Beijer Elec-
tronics for details). A speaker, which has programmable pitch and duration, comes standard, as
does a battery-backed real-time clock. Other options include: an audio decoder for playing
audio wave files, a hardware watchdog timer, and a 5 V/100 mA output from the auxiliary
serial port to power external devices.
The QTERM-G70 terminal stores the firmware and the user application in a compressed for-
mat in flash memory and then transfers them to RAM memory when the terminal is powered
on. The terminal is equipped with four megabytes of flash memory and sixteen megabytes of
RAM memory.
The outer legend can be customized with your logo/name or graphics. The inner legend under-
lay around the display can be customized with your touch keys and graphics.
The QTERM-G70 terminal requires a DC power source in a range of 8 to 26 VDC. This power
is supplied via the main DB9 serial connector. Other options for supplying power to the
QTERM-G70 are PoE (Power-over-Ethernet) and five volts from a well-regulated power sup-
ply via the main DB9 serial connector. Please contact Beijer Electronics for more information
about this option. The five volt power supply input option is only available on terminals with
the TFT display option.
