Product Information

Product Description

MW5501C is an Industrial wireless Modbus gateway providing a flexible platform to convert bi-directionally Modbus RTU/ASCII/TCP through wired and wireless Ethernet networks.  The ease-of-use configuration utility provided with Modbus Gateway can quickly select the hardware interface, and easily switch to the existing communication infrastructure.

This gateway supports:

  • IEEE802.11 b/g/n standards over 2.4GHz for Wireless connectivity
  • wired Ethernet through one RJ45 port
  • four most commonly used communication standards in Serial: RS-232/485 and 422 on one DSub-9 / 5-Pin Terminal Block Combo.

MW5501C has 1 combo serial port, 1 Ethernet port and Fast P2P file transfers.

Switching between Modbus Protocols
Modbus Gateway supports the standard Modbus protocol and is capable of converting any Modbus protocols between Modbus TCP, Modbus RTU, and Modbus ASCII for all supported hardware interfaces.

Modbus ID Routing
Modbus Gateway supports various types of hardware communication interfaces, Modbus protocol conversion and Modbus ID routing. These interfaces can integrate your existing and complex Modbus hardware configuration into a simple network that can be easily managed.


  • Designed for 802.11 b/g/n networks, FCC (USA), ETSI (Europe) certified
  • 1 x 100BaseT(X) Fast-Ethernet RJ45 port
  • 1 Software-selectable RS-232/485/422 ports, combo serial port
  • Bi-Directional Modbus TCP/RTU/ASCII conversion from serial to Ethernet or wireless and vice-versa
  • Advanced features include Virtual ID remapping, VirtualCOM mode, exception handling and many others
  • Supports WiFi-Direct for Simple Peer Pairing
  • Web server / Utility configuration
