3.2.7 USB Connector
An USB (device) interface is available via a mini-USB connector. This module supports USB 2.0 full-speed
(12Mbit/s) connections.
The on-board digital core logic (mainly processor and EEPROM) will be powered via USB in case no
other power supply is connected. This is useful for setting parameters and downloading TMCL programs
or for performing firmware updates. Using a USB connection to the host, the tasks outlined above can
be carried out inside a machine while the machine is powered off. Refer to chapter 3.4.1, please.
