UC-7122/7124 User’s Manual Getting Started
Starting Your UC-7122/7124 Computer
Connect the SG wire to the shielded contact located in the upper left corner of the UC-7122/7124
computer, and then power it up by connecting it to the power adaptor. It takes about 30 to 60
seconds for the system to boot up. Once the system is ready, the “Ready” LED will light up. The
light will stay lit until you shut down the computer.
Resetting Your UC-7122/7124 Computer
When the target computer stops responding, or an application locks up, or the target computer fails
to work normally, you may need to restart or reset the target computer’s operating system. We
provide four ways to restart or reset the operating system.
Warm-Start: When the computer is powered on, insert a pin into the “Reset” hole next to the
serial console, and hold for 1 to 2 seconds. The computer will reboot automatically.
Cold-Start: Unplug the power line and then plug it back in again. The computer will reboot
automatically.
Resetting to Factory Defaults: If the computer is not working properly, and you want to reset it
back to factory default settings, press and hold the “Reset” button for at least 5 seconds. The
buzzer will sound while the factory default settings are being loaded. After the factory defaults
have been loaded, the computer will reboot automatically.
Resetting the system: In rare circumstances, the TFAT file system may be damaged by executing
improper applications, or due to an unstable power supply. In this case, the computer may fail to
boot up if the TFAT table crashes. In order to get the system back up and running, you will need to
format the flash disk and reset the operating system. Note that all user files and configurations will
be erased. The following steps show how to format the flash disk through boot loader utilities.
Step 1: Power off the UC-7122/7124 embedded computer.
Step 2: Connect the UC-7122/7124 to your PC using the console port cable.
Step 3: Start a terminal program with the settings: Baudrate = 115200, no hardware flow control,
8 N 1, character set VT100.
Step 4: Hold in the “DEL” key on your PC.
Step 5: Power on the UC-7122/7124. You will be guided to boot loader utility menu.
