CHAPTER 2
QTERM-G75 TERMINAL
2.1 Product Description
The QTERM-G75 terminal is a large display Ethernet-enabled graphic terminal with
object-based programming. It features a robust list of industrial grade hardware features and
options.
The QTERM-G75 features a VGA, 640x480 pixel, active-matrix TFT LCD display (256 col-
ors). It uses a dual lamp cold-cathode fluorescent backlight (CCFL). The CCFL provides high
contrast and easy readability and is replaceable. 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-G75 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-G75 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-G75 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 eight megabytes of flash memory and 32 megabytes of
RAM memory. The Power-over-Ethernet units is equipped with four megabytes of flash mem-
ory and sixteen megabytes of RAM.
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-G75 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-G75 are PoE (Power-over-Ethernet) or five volts from a well-regulated power supply
via the main DB9 serial connector. Please contact Beijer Electronics for more information
about this option.
