DC-Out
A 5V DC output is available on the X2 connector. It is possible to control the output in order to
save power. The output is short circuit- (to ground), ESD- and transient protected. Make sure not
to exceed the current specification of the output and be aware that inrush currents of the external
equipment may exceed the specifications. It is recommended to install a fuse to protect the output.
This output must be enabled from the application. Please consult the RTCU IDE on-line manual for
more information.

Ethernet
The RTCU NX-200 offers an onboard IEEE 802.3 compatible 100BASE-T Ethernet MAC controller
and transceiver for communication with peripherals and back-end systems over standard Ethernet.
Please refer to the RTCU IDE documentation for details on the usage of this interface.
USB Host interface
The RTCU NX-200 offers two high-speed USB host ports on the standard USB A connector for
connection of various USB devices. The host port 1 connector includes locking latch that locks the
USB cable connector in position. To remove the USB cable, the locking tab needs to be pushed
slightly until the locking latch is released. The USB host ports can supply the external USB device
with up to 500mA each.
Please notice:
To reduce the total power consumption then DC-Out, USB host 1 and USB host 2
can not be enabled at the same time. Only two out of these three interfaces can be simultaneously
enabled. Please consult the RTCI IDE online help for further information.
Audio interface
The audio interface is available on the three 3.5mm jack connectors on the front side of the device.
The audio interface includes a microphone input and speaker output.
