Temperature warnings
The temperature in the user module as well as in the computer module of the
FIBREVision-MC4 variant is permanently moitored.
Before the temperature reaches the critical value, the user is warned through several
alarm signals:
USB and PS/2 signals of -ARU and -U variants
If you use a variant of the FIBREVision system that supports USB devices, it is neces-
sarily required to connect the USB CPU interface of the computer module (FIBREVi-
sion-CPU) with the USB interface of the computer.The interface is used to transmit
the data of the USB devices to the computer.
The signals of keyboard and mouse are also transmitted through this USB connection.
If you prefer to transmit the signals of keyboard and mouse through the PS/2 inter-
faces, connect the interfaces Mouse CPU and Keyb. CPU with the PS/2 interfaces of
the computer.
Support of any resolution
In principle, the FIBREVision system supports all resolutions that can be transmitted
through a single link interface according to the DVI specification 1.0.
This restriction mainly affects the pixel rate, which can reach from 25 MHz to
165 MHz. Therefore, resolutions between 640 x 480 pixels at 60 Hz and 1600 × 1200
pixels at 60 Hz are possible for the common timing standards by VESA DMT and
VESA SMT. 1920 × 1200 pixels at 60 Hz is transmitted according to VESA CVT-RB.
Almost any refresh rate and resolution within the technical constraints are possible.
The available display modes are largely dependent on the graphics card, the graph-
ics driver, the operating system and the connected monitor.
IMPORTANT: To protect the device from overheating, the video signal of the chan-
nels 2 to 4 is switched off as soon as the temperature reaches the critical value!
Alarm level Action
≥ 70 °C Blinking Sys-LED at device.
≥ 71 °C All four monitors of the user module display the image with a blinking frame.
≥ 72 °C All four monitors of the user module display the image with a fast blinking
frame.
≥ 73 °C Video channels 2 to 4 are switched off; the monitors 2 to 4 display no image.
The monitor of video channel 1 still displays the image with a fast blinking
frame.
IMPORTANT: Display modes that support interlace are not supported by the
FIBREVision system!
