4.4.3.
X102/X103 - Ethernet Connectors (ETH)
These connectors (X102 as ETH 1 and X103 as ETH 2, Figure 10) are Gigabit Ethernet 10/100/1000 Mbit/s, IEEE 1588
capable interfaces. 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 11.1.2.
4.4.4.
X105 - USB 3.0
The KBox A-103 provides one USB 3.0/2.0 interface. This connector (X105, Figure 10) allows connection of USB 3.0 or
USB 2.0 compatible device to the system. For pin assignment refer to subsection 11.1.3.
4.4.5.
X107/X108 - USB 2.0
The KBox A-103 provides two USB 2.0/1.1 interfaces. These connectors (X107/X108, Figure 10) allow connection of
USB-compatible devices to the system. For pin assignment refer to subsection 11.1.4.
4.4.6.
X109 - DisplayPort
This is a DisplayPort compliant interface realized using a standard DisplayPort connector. An external (digital) display
can be connected to the DisplayPort connector (X109, Figure 10). For pin assignment refer to subsection 11.1.5.
As the SMARC module does not support DP++ (dual-mode DisplayPort) only active converter
cables can be used together with the KBox A-103. Active adapters use additional chips to
make the conversion inside the adapter, regardless of whether the source supports DP++.
4.4.7.
X110 – Serial Port COM 1
This interface (X110, Figure 10) is provided as a 9-pin D-SUB connector; it is RS232 configured and allows the
connection of a serial peripheral. For pin assignment refer to subsection 11.1.6.
4.4.8.
X204 - Serial Port COM 2 (Option)
This interface (X204, Figure 10) is provided as a 9-pin D-SUB and allows the connection of a serial peripheral. It is
designed to support RS232 serial communication or can be factory configured for RS422/RS485 serial
communication via an adapter module. The RS422/RS485 modes can be configured via an on-board DIP switch (SW1)
on the RS422/485 adapter.
For configuration of COM 2 refer to 5.1.2 “Serial Port COM2 (X204) Configuration for RS422 or RS485 via DIP Switches”.
For pin assignment of COM 2 refer to the chapters 11.1.7 to 11.1.10.
In RS-422/485 mode, the termination of this port is configurable via DIP switch (see chapter
5.1.2, “Serial Port COM2 (X204) Configuration for RS422 or RS485 via DIP Switches”).
4.4.9.
X206 - Serial Port COM 3 (Option)
This interface (X206, Figure 10) is provided as a 9-pin D-SUB (female) and allows the connection of a serial peripheral.
It is designed to support RS422/RS485 serial communication and can be configured via onboard jumper J46
(Figure 23, pos. 3). The serial onboard header for COM 3 is J44 (Figure 23, pos. 5).
For configuration of COM 3 refer to 5.1.3 “Serial Port COM 3 (X206) Configuration of the Serial Port COM 3”.
For pin assignment of COM3 refer to the chapters 11.1.11 to 11.1.3.
