How to Network RS-232 Robot and Industrial Devices with WIZnet W55RP20 on PP-Ethernet-RS232? Summary PP-Ethernet-RS232 is a commercial RS-232-to-Ethernet converter module for connecting legacy serial devices to wired TCP/IP networks. The module uses WIZnet W55RP20, which combines an RP2040-class MCU with W5500-based Ethernet and a hardwired TCP/IP stack. In robotics and Industrial IoT systems, PP-Ethernet-RS232 can bridge controllers, sensors, motion subsystems, measurement tools, or maintenance ports into an Ethernet network without requiring the attached RS-232 device to implement…
