The Reset command (Message ID 64/0x40), will reset the MTi and activate the WakeUp procedure. The Reset command can be used when the sensor fusion algorithm outputs erroneous data or when you need to read out the eMTS device of the device. 

In the MT Manager however, the Reset command also disconnects the MTi from the WinUSB port. There is no automatic rescan, so the MTi seems 'lost'. A rescan however solves this situation. If you want to use the Reset command in MT Manager, make sure to use a serial-USB converter or a direct serial connection. 

In direct communication (UART, RS232/RS422/RS485), the Reset command won't shut off the MTi from the interface.
