WIZ505SR-RP is a compact sized serial to Ethernet module using the RP2040 MCU with W5100S Ethernet Chip. WIZ505SR-RP is a protocol converter that transmits data sent by serial equipment as TCP/IP data, and converts the TCP/IP data received through the network back into serial data to the serial equipment.

In addition, WIZ505SR-RP contains serial debug port(J1).

WIZ505SR-100 is the best fit solution to control user's serial device via Ethernet network.
