terminal to the factory settings simultaneously, regardless of which register set it is called
from!
Command 0x8000: Software Reset
Entering 0x8000 in register R7 initiates a full software reset for the terminal. All internal variables (positions,
latched values, errors etc.) are cleared or are set to defined values that are read from the EEPROM. The
internal circuits (D/A converter, output driver) are reinitialized during a software reset.
CAUTION
Software reset!
Power is removed from the output stage during a software reset. Ensure that your system
state permits this and that hazards for persons or machinery have been ruled out!
