B&B Electronics Setup
Below you will find the wiring setup and software configuration for the MESR901. Remember that the
pictures below are for reference—you will need to set up the serial configuration to match the settings you
chose in the ProTech. When multi-dropping the three modules together using RS-485/422, you will need
to assign each module a unique node address, which can be found on the front-panel Modbus
configuration screen on the ProTech.
