Introduction
W5500S2E-S1 is an industrial grade serial to Ethernet module. It supports TCP server, TCP client and
UDP three operating modes. The maximum serial baud rate is 1.152Mbps. W5500S2E-S1 supports
WIZS2E ConfigTool (Configuration Tool for Windows®), web page configuration and AT command to
configure the module.
W5500S2E-S1 uses the hardwired TCP/IP protocol Ethernet chip W5500. This enable a faster, stable and
secure Ethernet connectivity. With reference schematic(s) and guideline(s) in this user manual, it could
be greatly reduced the time and difficulty of the hardware design and development when comparing with
other approaches.
