Wireless That Just Works

cnReach Terminal Server

The cnReach™ Terminal Server delivers serial to Ethernet conversion enabling the addition or integration of serial connectivity to any wired or wireless TCP/IP network.

In addition to serial connectivity, the terminal server supports MODBUS polling at the edge that can be published via MQTT. Finally, the cnReach Terminal Server is managed with cnMaestro™ providing single-pane-of-glass management across the network.

Key Features

  • Add serial to TCP/IP conversion on any wireless or wired broadband network
  • Single-pane-of-glass management with cnMaestro to monitor/configure devices remotely
  • Flexible configuration enabling integration with most serial-based devices in the field today
  • Integrated MODBUS TCP to MODBUS RTU conversion
  • Supports TCP or UDP traffic and server or client modes
  • Daisy-chain multiple units to add more serial ports
  • MQTT publish/subscribe integration
  • Reduce traffic by up to 90% vs traditional polling
  • Make data available across entire organization
  • Integrated local MODBUS polling at the edge
  • Data concentrator applications to reduce polling
  • PLC local logic to add intelligence at the edge
