Communication

 

This  series  power  meter  provides  an  RS-485  slave  port  and  adopts 

Modbus-RTU  protocol.  All  devices  are  connected  in  a  bus  line  by 

twisted-conductor  and  shielded  cable.  Up  to  32  stations  can  be  connected 

together  in  a  segment.The  cable  at  the  start  and  end  of  a  segment  is 

terminated with resistors. 

One  more  communication  is  realized  by  connecting  extension  module  to 

meter.  As  for  detailed  information,  please  refer  to  user  manual  of  DM10, 

DM11, DM12 and DM13.
