5.4 LED Indication
The DWETH111 has tri-color (RGB) LEDs for conveying device state to users. In normal operation the device state can be
determined using the table below:
Network Status

1.0S
OFF Network
Green

1.
This table denotes normal LED operation. The CUWB network can be configured to show different patterns on the
LEDs
2.
Power On Reset (POR) occurs only on system reset. This will happen when charging a dead battery, on reboot after
firmware update, and when the device resets due to system watchdog.
The RGB LED also conveys error states to the user. An error is indicated by a 500mS red flash followed by a color
sequence. The following color sequences are used to decode error states:
