UC-7400-CE User’s Manual Getting Started

Starting Your UC-7400-CE Computer
Connect the SG wire to the shielded contact located at the upper left corner of the target computer,
and then power on it 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 and stay on till you
shutdown the computer. For a computer with a LCM display, the network address settings and
other system information will appear on the LCM.
Resetting Your UC-7400-CE Computer
Warm/Cold Start: You seldom need to perform a warm-start or a cold-start on a UC-7400-CE
computer. In some cases where the computer stops responding, an application locks up or when
you upgrade the firmware, it may be necessary to perform a warm-start or a cold-start.
Warm-Start: In power-on state, insert a pin into a “Reset” hole next to the serial ports and hold
the pin for 1 or 2 seconds. The computer reboots itself.
Cold-Start: Switch off and then switch on the power again. The computer reboots itself right
away.
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 to Default” button for at least 5 seconds.
The buzzer sounds while the factory default settings are loaded. After the factory default has been
loaded, the computer reboots itself. Do not confuse this with the “Reset” button.
Operating UC-7400-CE Computer Via Serial Console
The serial console port (next to two LAN ports) gives users a convenient way of connecting the
development workstation to the console utility of the target computer. This method is particularly
useful when using the computer for the first time.
After you have wired a serial cable, go back to the development workstation and start a terminal
program (e.g., HyperTerminal) by using the settings shown below for the serial console port.
