Set default configuration (30 [1E Hex]) 

All parameters revert to default condition. It is the same effect as DIP Switch S1 (8). Command [2C Hex]

Start permanent scan with overhang monitoring (32 [20 Hex]) 

The measurements will be repeated in approx. 10 ms cycles for a 30 beam light curtain. Overhang monitoring is 
performed at the same time. After the measurement is completed, the result may be repeatedly read out by 
reentering the command 32 [20 Hex].  
Sending command 32 anew, before sending command 34, will reset the scan counter and reset the status values 
noted in command 35 (see 2.2.5.14).
