 An industry compliant RS-485 Modbus RTU interface is built in and the [[hardware:​wattmons|Wattmon]] acts as a Modbus master to collect data from various devices such as inverters, power meters, current sensors, etc. Up to 8 Modbus RTU-compliant slave devices and 1 Modbus TCP device can be daisy-chained to the interface, and the Modbus can be configured for any baud rate up to 115200 with different parity settings as required. An industry compliant RS-485 Modbus RTU interface is built in and the [[hardware:​wattmons|Wattmon]] acts as a Modbus master to collect data from various devices such as inverters, power meters, current sensors, etc. Up to 8 Modbus RTU-compliant slave devices and 1 Modbus TCP device can be daisy-chained to the interface, and the Modbus can be configured for any baud rate up to 115200 with different parity settings as required.
  
-For most applications only the RS-485 A and B lines need to be connected to the device to be monitored and controlled. For example, all the [[hardware:Wattmons]] have drivers for these inverters:+{{:hardware:wattmons:20190223_wattmonmini_modbus.jpg?​nolink&​400|}}

 In addition, if needed, the 5V and GND lines can be connected for device power. Although designed primarily for a two-wire connection to an RS-485 capable device, by modifying a Cat5 cable any of the Modbus devices we have developed (voltage, current, frequency, <tooltip title="​Pulse Width Modulation">​PWM</​tooltip>,​ relay outputs, etc., see [[hardware:​Modules]]) can also be connected to the WattmonMINI screw terminals. In addition, if needed, the 5V and GND lines can be connected for device power.
