System Led S1 And S2 - Logic IO RTCU MX2 turbo Technical Manual

RTCU MX2 turbo Technical Manual V2.04

System LED S1 and S2

The RTCU is equipped with two system LED's which shows the status and possible errors of the
RTCU unit.
The different patterns are listed in the table below. If the color of the system LED S1 is yellow, the
unit is actively communicating with the RTCU IDE (or another program, supporting the RTCU
RACP protocol).
The single yellow LED is signaling either the GSM module activity, or if all other LED's are off,
that the RTCU is in the "wait for event" low power state.
