³ Operating: 10% to 90% (non condensing) ³ Non operating: 5% to 95% (non condensing)
Restriction of Hazardous Substances (RoHS)
All boards in the pITX embedded line product family are RoHS compliant.
3.7 MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of manufac­turer’s test data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore calculation used is 'method 1 case 1'. In that particular method the components are assumed to be operating at a 50% stress level in a 40°C ambient environment and the system is assumed to have not been burned in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is specified at 50°C, so in that sense the following results are slightly conservative. The MTBF values shown below are for a 40°C in an office or telecommunications environment. Higher temperatures and other envi­ronmental stresses (extreme altitude, vibration, salt water exposure, etc.) cause lower MTBF values.
³ System MTBF (hours): 243526
Note: Fans usually shipped with KONTRON Technology A/S products have 50.000-hour typical operating life. The above esti-
mation assumes no fan but a passive heat sinking arrangement. Estimated RTC battery life (as opposed to battery failures) is not included in the MTBF calculation. The RTC battery lifetime has to be considered separately. Battery life depends on both temperature and operating conditions. When the KONTRON unit has external power; the only battery drain is from leakage paths.
KTD-S0044-G Page 10 Equipment Design Rule

8.3 Limitations
The contacts for USB devices are protected and suitable to supply USB devices with a maximum input current of 500mA. Do not supply external USB devices with higher power dissipation through these pins.
8.4 USB Client Interface
The connector J1900 provides the client interface. You need the client functionality for changing the bootloader or update a corrupted bootloader. Together with the recovery pin (see chapter 'Crisis Mana­gement') and dedicated software on a desktop computer as well as a standard USB cable (both ends with Type-A connector) and a special KONTRON USB adapter cable (KAB-USB-2, part number 96054-0000-00-2) the upload is easy.

10 Serial Interface
Three serial ports provide asynchronous serial communication with RS-232 interfaces. They are 16450/ 16550 UART compatible and support 16-byte FIFO buffers for transfer rates from 50 Baud to 115.2 kBaud. Following the connector assignment:
J2200 x UARTA/UART1 J2201 x UARTB/UART2 J2202 x UARTC/UART3
10.1 Connector
The serial ports are available through the connectors J2200, J2201 and J2202 (5 pins).

10.2 Serial Console
Most operating systems have a defined serial console. The KTT20/pITX uses the third serial port (UARTC/ UART3) on connector J2202 for this purpose. Normally the serial console needs only three signal lines (TXD, RXD and GND). The serial port is assigned to the environment variables stdin, stdout and stderr. If you use U-Boot as bootloader you can interact with U-Boot via a USB keyboard and a standard terminal program on a desktop computer. The following overview shows the default serial settings:

If the board does not boot up or in the case of custom firmware usage (for example the replacement of the
TM
KONTRON bootloader) you can overwrite the content of the SPI

A desktop PC with a Windows® or Linux® operating system
S
A special NVIDIA® USB driver (only Windows®)
S
One USB Type A cable and the KONTRON adaptor cable KAB-USB-2
S
Two pushbuttons or one pushbutton and one jumper or something similar

An actual bootloader image file
For the next step you should create a link from the KTT20/pITX client port to a desktop PC (see chapter 'USB Client Interface'). Make sure that you have the power cable plugged-in. Then connect the pushbuttons or a pushbutton/jumper combination to the pin header J1400 (button or jumper) and J900 (button).

J900
J1400
To set the board into recovery mode first the pushbutton J1400 (if you use two buttons) and then the pushbutton J900 must be pressed until the LEDs go on.
