WARNING!

 

Dip switches configuration is active only after a reboot! 

 

 
So, for example using the RMS measure with 0 A input the Output voltage is 0V but using the Bipolar measure 
with 0 A input the Output voltage is 5V. 
 

 

MODBUS RTU PROTOCOL 

 
The Modbus protocol supported by the T201DCH50-100-300 is: 
 

 

Modbus RTU Slave  
 

For more information about these protocols, please refer to the Modbus specification website:  
 

http://www.modbus.org/specs.php
