Introduction
The Kaiterra Square is a commercial air quality monitor that supports multiple communication methods,
including Modbus.
Modbus is a serial communications protocol. Developed for industrial applications, Modbus is relatively
easy to deploy and maintain. Modbus uses the RS485 or Ethernet as its wiring type. Modbus supports
communication to and from multiple devices connected to the same cable or Ethernet network.
The Kaiterra Square provides Modbus/RTU support via the RS-485 port on the device. Kaiterra Square
can still upload data to the cloud via Wi-Fi or Ethernet when Modbus is used for local communication.
Note: Before setting up Modbus for your Kaiterra Square, please make sure your device is
running the latest firmware and make sure the latest version of Kaiterra Enterprise Configuration
Tool is installed on your computer or smartphone.
