LORDWORLD

LORDWORLD RS232 to RJ45 Industrial Serial Server development board

SKU CH-4B4X-DXPAY

Industrial RS232-to-Ethernet gateway with Modbus, MQTT and JSON conversion for data acquisition and instrument monitoring

  • Combines serial server, Modbus gateway and MQTT gateway in one unit
  • Designed as an industrial RS232 data acquisitor and IoT gateway
  • Features RS232 and Ethernet ports with optional POE support
  • Screw-terminal power input and rail-mount case for quick installation
  • Suits data acquisition, safety IoT and intelligent instrument monitoring applications

Industrial IoT Gateway

The LORDWORLD RS232 to RJ45 converter is a compact development board that bridges legacy serial equipment to Ethernet networks. It serves engineers and system integrators who need a rail-mountable data acquisitor for industrial monitoring, security, and instrument applications.

Multi-Protocol Headroom

The unit combines serial server, Modbus gateway, MQTT gateway, and RS232-to-JSON functions in one device. It handles TCP Server, TCP Client, UDP, and UDP Multicast modes, but lacks wireless connectivity and Power over Ethernet unless the optional POE variant is selected.

Screw Terminals and Rail Mount

The board ships with screw-terminal power input and a DIN-rail enclosure for secure cabinet installation. No software licence or configuration utility is bundled, so users must supply their own toolchain for protocol mapping and device management.

Questions about this item

Will the RS232 port on this LORDWORLD board talk to my legacy PLC that uses a standard DB9 cable?

Yes, the on-board RS232 interface uses the common serial signalling your PLC expects, so a straight-through DB9 cable will carry data between the two devices.

How can I confirm the Ethernet link is passing Modbus TCP packets after I mount the unit on the DIN rail?

Connect a PC to the same LAN, open the built-in web interface or a Modbus polling tool, and verify that register reads from the attached serial device return the expected values.

Does the package include a power supply for the screw-terminal input, or do I need to source one separately?

A power supply is not included; you must provide a suitable DC source that connects to the screw terminals on the board.
