QTERM-Z60 TERMINAL
6.1 Product Description
The QTERM-Z60 terminal is an economical graphic terminal with object-based programming.
Two different models of the QTERM-Z60 exist to suit any environment and budget. In general,
the Z60/H version is NEMA-4 rated and has a user-selectable serial port while the Z60/L is
NEMA-12 rated, has one EIA-232 serial port and a slightly different display.
The QTERM-Z60 features a QVGA, 320x240 pixel, 256 color STN color LCD display. It uses
a cold-cathode fluorescent backlight (CCFL). The CCFL provides high contrast and easy read-
ability and is replaceable. The contrast is software controlled and temperature compensated.
The analog-resistive touch screen covers the full viewable area of the display as well as the
pre-labeled legend underlay around the display.
The QTERM-Z60/H is equipped with one user-selectable serial port (EIA-232, EIA-422, or
EIA-485). The interface is selected using DIP switches. The QTERM-Z60/L is equipped with
one EIA-232 serial port.
A speaker, which has programmable pitch and duration, comes standard as does a 5 VDC 200
mA output from the interface connector to power external devices. An external reset signal
also comes standard to allow other devices to reset the QTERM-Z60.
The QTERM-Z60 terminal stores firmware and user applications in a compressed format in
flash memory and then transfers them to RAM memory when the terminal is powered on. The
terminal is equipped with two megabytes of flash memory and sixteen megabytes of RAM
memory.
The QTERM-Z60 terminal requires a DC power source ranging from 8 to 32 VDC. This
power is supplied via the main interface connector.
