A Master Reset will delete all settings and logged data. This data should be 
downloaded  to  a  PC  using  the  PCME  PC  software  before  carrying  out  a 
Master Reset.  
 

 

To perform a Master Reset

The  Communications  Mode  is  set  by  PCME  prior  to  installation  and  should  have  been  checked 
during the system installation. 
 

To check the Communications Mode

Mode 

Baud Rate 

Parity 

Standard 

ASCII 

19200 

Odd 

Optional 

RTU 

19200 

None 

 
If problems are encountered communicating with a sensor, check that the sensor communication 
setting (SW101) is the same as the multicontroller Sensor Comms Mode setting. 

6.4

 

Autodetect Sensors 

 
Sensor channels can be added to the multicontroller by autodetect or manually. 

 
The  manual  mode  should  only  be  used  to  add  sensors  when  manual  control  of  the 
order  in which the devices are displayed is required or only specific  sensors are to be 
added. 
 

In  the  ‘Autodetect’  mode  the  multicontroller  scans  all  the  modbus  addresses  to  identify  all  the 
sensors in the network.
