Mainstream Modbus Adapter

The Modbus Adapter is a device that is external to the Mainstream and works by connecting to the Mainstream communications port, allowing the customer to read measurement data using the Modbus RTU protocol. The Adapter can operate using Modbus RTU over RS232 or RS485 (half and full duplex), it can accept external power supplies and is currently available for use with fixed units.

  • Relays single or multiple measurements from the Mainstream.
  • Configurable for fast operation or power saving operation.
  • Built-in self-diagnostics.

Many popular products such as telemetry units and dataloggers incorporate Modbus communications. Many of these devices are already embedded throughout the water industry infrastructure, the Modbus Adapter bridges the gap between the Mainstream and these devices.

The Mainstream Modbus Adapter makes the reliability, accuracy and affordability of the Mainstream, available to anyone who already has this technology in place or is looking to upgrade their communications capabilities.
