Green rectangular development board with four RJ45 ports and screw terminals, wall-mount metal case

LORDWORLD

LORDWORLD 4-Ch RS485 to RJ45 Serial Server POE Development Board

SKU CH-2PFS-YG9MV

Four-channel RS485-to-Ethernet gateway with independent port operation, Modbus and MQTT support, PoE power, screw terminals and DIN-rail or wall mounting

  • Four RS485 channels operate independently for simultaneous data streams
  • Combines serial server Modbus gateway MQTT gateway and JSON conversion
  • Screw terminal power input ensures stable industrial connections
  • Wall or rail mounting options simplify installation and expansion
  • PoE function powers the device through the Ethernet cable

Four-channel RS485 gateway

The LORDWORLD board converts four independent RS485 channels to Ethernet, letting each serial line operate without interference. It functions as a serial server, Modbus gateway and MQTT gateway in one unit. Developers and system integrators can use it to bridge legacy field devices to IP networks.

Capacity and headroom

Four channels run simultaneously, so a single device can aggregate multiple sensors or actuators without adding extra converters. The design handles bi-directional traffic across all ports, but throughput will be limited by the Ethernet link and the serial baud rates chosen. Projects needing more than four serial drops will require additional hardware.

Build quality and mounting

A screw terminal provides a secure power connection that resists vibration in industrial cabinets. The enclosure supports both wall-mount and DIN-rail installation, allowing quick deployment on panels or inside junction boxes. This mechanical flexibility reduces wiring time during commissioning and future expansion.

Questions about this item

Will the four RS485 channels keep running independently when I connect legacy Modbus devices?

Yes, the four RS485 channels operate independently at the same time so each legacy device communicates without affecting the others

How can I verify the serial-to-Ethernet link is working after I wire the screw terminals?

Check that the Ethernet port shows a link light and that your Modbus or MQTT client receives the expected JSON payload from each channel

Does the package include a DIN-rail clip and a PoE injector, or must I buy them separately?

The board comes in a wall-mount and rail-mount case; a PoE injector is not included and must be sourced separately
