Hardware Introduction

Internal SD Socket
The UC-7112 and UC-7112 Plus have an internal SD socket for storage expansion that accepts Secure Digital
(SDHC) SD 2.0 memory cards, for up to 16 GB of additional memory in the UC-7112 Plus, or 32 GB in the
UC-7112.
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 the data
being transmitted. The reset button is NOT designed to hard reboot the UC-7110/7112 series embedded
computer.
ATTENTION
For the UC-7110-LX and UC-7112-LX, 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.
For the UC-7112-LX Plus, resetting the embedded computer to factory defaults WILL cause the user directory
to be reformatted; the files in the /home directory will be deleted, and 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.
