Slave Id Addressing - RHINO RMCS –2303 Operating Manual

Slave ID Addressing

Multiple drives with different slave addresses can be used with a single controller on single UART bus. For
this all drives should have a unique Slave Address. Using the GUI software or Modbus commands, the slave
ID can be set from 1 to 247. However, slave ID from 1 to 7 can be set using physical jumpers also. As shown
in the image below there are three jumpers marked by a red circle shown in the image below.
The three jumpers JP1, JP2 and JP3 can be set in the configuration as per the below table to provide a
physical slave address to the drive. In the below table a value of '0' corresponds to a state where the jumper is
not connected and a value of '1' corresponds to a state where the jumper is connected. If none of the jumpers
are connected the drive has been programmed to use the Slave ID 11 in default mode which can be changed
from 1 to 247 using GUI software or Modbus commands.
Drive will check jumpers on startup. If no physical jumper is connected it will use programmed slave id.
