UC-7112 Plus/7112/7110 Hardware User’s Manual Hardware Introduction

Internal SD Socket
The UC-7112 Plus and UC-7112 have an internal SD socket for storage expansion. A Secure
Digital (SD) memory card compliant with the SD 1.0 standard can be used to provide up to 1 GB
of additional memory space. To install an SD card, first remove the outer cover of the embedded
computer to access the SD slot. The internal SD slot is located on the back of the bottom board, in
the slot on the right side of the UC-7112 and UC-7112 Plus, but lower than the cover screw. Plug
the SD card into the socket directly and remember to “push in” the SD card first if you want to
remove it.
Additional Functions
Reset Button
Press the “RESET” button continuously for more than 5 seconds to load the factory default
configuration. After loading the factory defaults, the system will reboot automatically. The System
Ready LED will blink for the first 5 seconds. We recommend that you only use this function if the
software is not working properly. To reset the µClinux system software, always use the software
reboot command (reboot) to protect the integrity of data that is being transmitted. The reset button
is NOT designed to Hard Reboot the UC-71xx series embedded computer.
ATTENTION
Restoring default settings preserves your data
Resetting the embedded computer to factory defaults will NOT cause the user directory to be
reformatted, and the user’s data will NOT be deleted. The reset button only causes a configuration
file to be loaded. All files in the /etc directory will revert to their factory defaults, but all other user
data will remain intact in the Flash ROM.
Please note that if there is a problem with the /etc directory, the embedded computer may be
unable to restore the factory default settings.
ATTENTION
This function only takes effect when the user directory is working correctly. If the user directory
has crashed, the kernel will automatically load the factory defaults.
Real Time Clock
The real time clock in the UC-71xx embedded computers is powered by a lithium battery. We
strongly recommend that you get help from MOXA’s technical support team to replace the lithium
battery. If the battery needs to be changed, contact the MOXA RMA service team for RMA
service.
ATTENTION
The battery may explode if replaced by an incorrect type. To avoid this potential danger, always be
sure to use the correct type of battery.
