Qlarity-Based Terminal Hardware
Touch keys can also be defined in your user applications at any location on or around the dis-
play. Touch keys may be any size.
1.3.2 Keyboard
Using the optional PS/2 port, a standard PC keyboard may be used in addition to, or in place
of, the touch screen. Power On Setup, the terminal setup utility, recognizes both touch keys
and keyboard keys.
1.3.3 Keypad
The QTERM-G70 terminal can optionally include electronics for attaching an external keypad
with up to 8 columns by 8 rows and up to 6 keypad LEDs. Contact Beijer Electronics for more
information.
The keypad option will add 10 mA to the total current draw of the terminal plus the current
driven out the LED outputs pins. The LED outputs are five-volt open-collector signals with a
1000 Ohm series resistor. This results in an approximate maximum output current drive of 5
mA on those pins. There are two connectors on the keypad module to facilitate connecting dif-
ferent sized keypads. The pinouts for those connectors are shown in the following tables.
