Reset TCR Device Profile

LTR Blinking fast

If the left LED is blinking fast the device has been locked due to an invalid device profile. This happens if you update from a V1.x to a V2.x firmware or if you downgrade the firmware back to an older version.

Please follow this procedure to initialize a fresh device profile.

1. Connect via USB

Connect your device via an USB-Cable. Then use a terminal emulation program like RealTerm to send commands to the device. See the CLI documentation for more details on how to use the command line interface.
