Chapter 10: CRTs and TFT flat panels
Description
The video system on the XE–700 SBC supports CRTs and TFT flat panel displays.
Displays from CGA through XVGA are supported. The XE–700 SBC supports 3V
flat panel displays through the connector. 5V panels must be powered from an
alternate source.
Standard VGA monitors with analog inputs are connected using a 2 mm VGA–12
cable (p/n 6392) connected to J3. Flat panel displays are connected using a 40-pin
connector.
Video features
Below is a list of standard video features installed on the XE–700 SBC:
CRT support with resolutions to 1280 x 1024 x 16 at 60 Hz
Flat panel support with resolutions to 1024 x 1024 x 18
Simultaneous mode operation for CRT and flat panel (see below)
Simultaneous mode operation
The STPC Atlas CPU supports simultaneous mode video operation. Once a flat
panel driver has been programmed into the video BIOS, both a CRT and a flat
panel can be viewed at the same time. Note, however, that the CRT display might
not fit the screen properly if the resolution for the flat panel does not match the
resolution of the CRT.
Connecting a monitor
To use a monitor or a flat panel, the Video switch SW4 position 3 must be On. This
is the default configuration. The 10-pin connector at J3 supports an analog
CGA/VGA/SVGA/XVGA CRT color or monochrome monitor. The 2 mm VGA–12
cable connects to J3 and provides a DB–15 video mating connector for a CRT. Refer
to figure 10–1 for a diagram of connecting a CRT, and Table 10–1 for the pinout for
J3.
The XE–700 SBC supports both an analog monitor and/or a flat panel display. The
default video BIOS shipped on the XE-700 supports CRT only. The TFT enabled
video BIOS supports both TFT and CRT interfaces. This BIOS is user programmed.
