User Manual version 2.1
OPEN (660) 120/140/150
5-50
The user can use the I/O interfaces located at the rear
side of the chassis to connect external peripheral devices,
such as a mouse, a keyboard, a monitor, serial devices or
parallel printer…etc. Before any connection, make sure
that the computer and the peripheral devices are turned
off.
5.1. VGA Interface
The OPEN (660) 120/140/150 II has a 15-pin analog RGB
connector located at the rear side of the chassis. It can
support its own LCD display and an expansion CRT or
analog monitor at the same time. However, as the LCD
panel used in the 14.1” & 15.1” system (OPEN (660)
140/150) is of the resolution of 1024 x 768 and in 12.1”
system (OPEN (660) 120) is 800 x 600, therefore, to
support a CRT or analog monitor simultaneously, the
monitor’s VGA resolution has to be set to 800 x 600 for
OPEN (660) 120 and 1024 x 768 for OPEN (660) 140/150.
The connection to an analog monitor is an easy plug-in of
the VGA D-SUB 15-pin connector to the RGB interface.
There is some application software that is to be executed
in 800*600 resolution. When the software is running
under OPEN (660) 140/150, only part of the screen will
show on the LCD display. If the application has to run in
full screen, you need to update the system VGA drivers
with an auto expansion utility. However, due to
resolution limitation, the text mode will look slightly
distorted.
