6. Data Communication 

 

6.1. Hardware Configuration 

 
6.1.1. System 
 
The  PSU  supplies  power  to  the  AQM.  The  current  and  relay  outputs  of  the  AQM  communicate  measurement 
data to the tunnels' DCS system. 
 

 

 
 

 

 
 

6.2. Address Numbers 

 
Because communications between the interface and the sensor is serial digital, it is necessary for each sensor 
to be allocated an address number 

– 

the default address is 1 and should not be changed
