X101/X201 – Power Input Connectors
The 3-pin connector (X101) and the optional second power connector (X201) provide the power connection of the
KBox C-103-CFL system to an appropriate DC main power supply (see Figure 14 and Figure 11). For pin assignment
refer to the subsection 13.1.1.
If a second power supply is connected to the KBox C-103-CFL, only the particular power
supply with the higher supply voltage will be used (no power sharing), the other power
supply is redundant. Active and redundant power supply can change during operation
without interruption.
The external cable connector is a Phoenix PSC 1,5/ 3-M, 3-pin plug with an SCT-D-SUB 9-KG housing. This power plug
is delivered along with the KBox C-103-CFL. Please observe the section 9.1 ”Connecting to DC Main Power Supply”. The
mating connector is a Phoenix PSC 1,5/ 3-F connector.

X102/X105/X108/X111 - Ethernet Connectors (ETH)
These connectors (X102/X105/X108/X111, Figure 11) are Gigabit Ethernet 10/100/1000 Mbit/s, IEEE 1588 capable
interfaces. X102 optionally provides a PoE (Power over Ethernet) option (the PoE module has to be developed on
project base). The connectors are standard 8-pin RJ45 type connectors with status LEDs:
Activity/link: green = link up; green blinking = activity.
Speed: off, green, yellow (10/100/1000 Mbit/s).
For pin assignment refer to subsection 13.1.2.
4.5.3.
X103/X106/X109 - USB 3.0
The KBox C-103-CFL provides three USB 3.0/2.0 interfaces. These connectors (X103/X106/X109, Figure 11) allow
connection of USB 3.0 or USB 2.0 compatible devices to the system. The maximum current available depends on the
ambient temperature: Below 40°C it is 1 A (100%), above 40°C there is a derating of 2.5% per degree. So at 60°C the
maximum current available is 500 mA (50%). For pin assignment refer to subsection 13.1.3.
4.5.4.
X104/X107/X110 - USB 2.0
The KBox C-103-CFL provides three USB 2.0/1.1 interfaces. These connectors (X104/X107/X110, Figure 11) allow
connection of USB 2.0 or USB 1.1 compatible devices to the system. The maximum current available depends on the
ambient temperature: Below 40°C it is 500 mA (100%), above 40°C there is a derating of 2.5% per degree. So at 60°C
the maximum current available is 250 mA (50%). For pin assignment refer to subsection 13.1.4.
