If enter “tool=1” in the CMD window and clock CMD button,the message will change and Aurora will operate.

Application Note

5. Aurora Setup (5/5)

Aurora Operations

[16]

Commands1. TCTOOL mode : “tool=0”2. Aurora mode : “tool=1”

Application Note

6. Notices

We can change the modes by entering new command in Aurora command window. But, the command is available in only Aurora tool.

At first USB connection, TCTOOL mode is worked.

For updating the Firmware, re-build the master and slave together.
