X114 - RS232/422/485 Port
The RS232/422/485 interface (X114, Figure 11) is provided as a 9-pin D-SUB connector. It allows you to connect a
serial device to the system. A special feature of this port is that it also can be configured as dual RS422/485 port.
No special OS driver/SW is needed. For configuration refer to chapter 11/ “uEFI BIOS”.

POWER Button and PWR LED
Figure 15: Detail - Power button and PWR LED/Rescue button and RSQ LED
The power button (PWR, Figure 15, pos. 1, Figure 11) is used to power the KBox C-103-CFL on or off.
By pressing the power button for longer than four seconds a forced system shutdown will be initiated, before the
power to the system is turned off.
Caution: Performing a forced shut down can lead to loss of data or other undesirable effects!
The power LED (marked PWR, Figure 15, pos. 2, Figure 11) is on green steady when power is applied to the system.
Prerequisite:
The KBox C-103-CFL has to be connected to an appropriate main power supply (DC).
Even when the system is turned off via the power button there are parts of the system still
energized.
The unit is only completely disconnected from the DC mains, when the power is removed.
As soon as external power is applied to the main input power connector X101 (Figure 14) or to the optional second
power connector X201 (Figure 11), the KBox C-103-CFL boots up and then starts the operating system and application
where available.
To perform an orderly shutdown of the system, press the PWR button and the system shuts down under the control
of the operating system.
Once the system has been shut down, it can restarted by pressing the PWR button (assuming that power is still
applied to the main input power connector, X101).
