Warning: Do not mix the Fan Connector and the ccTalk connector. If mounting Fan into ccTalk
connector Fan might be damaged.
Note: The backlight adjust signal uses the Pulse Width Modulation (PWM) technique. A proto- type cable
with open ends is shippable from KONTRON (part number 821515).
Note: 1) To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
Warning: Check the U-Boot Setup for correct settings for your panel – not doing so might cause permanent damage to your panel.
Connecting a Flat Panel
 Check if you have the correct panel cable. Inspect the cable for damages.
 Switch on the power supply and activate/save the desired settings with help of the U-Boot
bootloader (for further details see the 'Software Guide' chapter 'U-Boot Setup'). Switch off
the power supply.
 Connect an external power supply for the correct backlight voltage (except the power supply
complies with the backlight voltage).
 Connect the cable to the flat panel connector J1 on the KTT30 and connect the other end to
your display.
 Switch on the power supply. If you only see a blank screen contact your distributor for tech-
nical support.
8.2 Fan Connector
For an optional fan use the connector J15 (4 pins). The interface only supports +5V fans and operates with
a PWM output (Control) which allows the control of fan speed.
Header Pin Signal Description Type
1 Control PWM output O-5.0
2 Sence Tacho signal (open drain) I
3 VCC5 1) Power +5V PWR
4 GND Ground PWR
