LED Indicators

Three bi-colored (red and green) and a single yellow LED indicators are present on the front of the
unit (see the graphical overview).
Two bi-colored LED (A and B) are available to the user, and the remaining two LEDs (S1 and S2) are
signaling the status and possible errors of the RTCU device.

User LED A and B

LED A and B is composed of two individually controllable LEDs:
•
LED named A on the front consists of LED 1 (green) and LED 2 (red).
•
LED named B on the front consists of LED 3 (green) and LED 4 (red).
The LEDs are easily accessed from within the application program, and it is possible to mix the LEDs
to obtain a third color: yellow. Please consult the RTCU IDE documentation for more information.

System LED S1 and S2

The RTCU is equipped with two system LEDs, which show the status and possible errors of the
RTCU device.
The different patterns are listed in the table below. If the color of the system LED S1 is yellow, the
device actively communicates with the RTCU IDE (or another program supporting the RTCU RACP
protocol).
The LED S2 signifies either the cellular engine activity or all other LEDs are off, that the RTCU is in
the "wait for event" low power state.
