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 3 modules together using RS-485/422, you will need to assign each
module a unique node address, which can be found in the Modbus configuration
screen on the ProTech.
