Invoke 2D Mode (*<)
The *< switches the control unit from 3D to 2D Mode. The serial port is
set to 1200 bps: 7 data bits, no parity, and 1 stop bit.
Software Reset (*R)
The *R command resets the control unit. You can issue this command in
any 3D reporting mode.
Wait at least 1 second after the software reset command before sending
any other commands. This allows the initialization process to complete.
