LED Indicators
LED indicators are located on the front panel of ThinkCore DA-660. DA-660-16 has 35 LED
indicators and DA-660-8 has 19 LED indicators. The only difference between these two products
lies in the serial port indicators. Refer to the following table for information about each LED.

Reset-type Buttons
The ThinkCore DA-660 has a reset-type button. The button labeled Reset returns DA-660 to the
factory default parameter configuration.
Reset Button
Press the Reset button on the front panel continuously for at least 5 seconds to load the factory
default configuration. After the factory default configuration has been loaded, the system will
reboot automatically. The Ready LED will blink on and off for the first 5 seconds, and then
maintain a steady glow once the system has rebooted.
We recommend that you only use this function if the software is not working properly and you
want to load factory default settings. To reset an embedded Linux system, always use the software
reboot command />reboot to protect the integrity of data being transmitted or processed. The
Reset button is not designed to hard reboot the ThinkCore DA-660.
ATTENTION
Linux OS: DA-660-8/16-LX
Pressing the Reset button will only load the configuration file. All files in the /etc directory will
revert to their factory defaults, and all user data in the Flash ROM will be wiped out.
WinCE OS: DA-660-8/16-CE
Pressing the Reset button will only load the default settings (i.e., the default registry values). All
user data NOT in the Flash ROM will be wiped out.
LCM Screen
The ThinkCore DA-660 has an LCM screen on the front panel. The LCM can display 16 columns
and 2 rows of text. After the DA-660 successfully boots up, the LCM will display the model name
and firmware version as below:
D A - 6 6 0 - 1 6
V E R . 1 . 0
