2.2.5 Optional Dual and Quad EIA-232 Serial Port Card
An additional two or four EIA-232 serial ports can be added to the QTERM-G75. These serial
ports have all necessary signals for EIA-232 serial communications and are wired as
Data Terminal Equipment (DTE).
The additional serial port option will add approximately 10 mA to the total current draw of the
terminal plus 15 mA per connected serial cable.
The following table shows the pinouts for the additional serial port option.
2.2.6 Optional Power-over-Ethernet Module
The optional Power-over-Ethernet module allows the user to provide power and communica-
tions to the QTERM-G75. The power can be provided from an IEEE 802.3af compliant hub or
switch as well as from a standard power supply.

2.3.1 Touch Screen
The QTERM-G75 touch screen provides user input through any number of touch keys located
on or around the display. The standard key legend shown in Figure 12 provides areas for five
soft keys down each side of the display. A custom legend underlay can be ordered to personal-
ize the terminal for your application.
