The extension communication LED (COM2) lights up (orange) for 20 ms after sending
each package through the extension ports. As long as the module receives/sends
packages, the extension communication LED blinks continuously.
The ALM LED is off by default, the function is programmable through the LED_ALARM
component; it blinks very softly if there is a fault during the start-up of Sedona Virtual
Machine.
During the
device’s
reset, when the 6
th
switch in the S1 - PROTOCOL DIP switch is on
(default settings restoration mode), the power LED (ON) blinks in 300 ms time
intervals. After the switch 6 is switched off, the power LED is lit permanently, and the
default settings are restored.
If the device remains in the bootloader status, the power LED (ON) and the
communication LED (COM1) blink alternatively. The communication LED keeps its
functionality and blinks also after sending/receiving data packages.
