WIZ750SR is the compact sized serial to Ethernet module using W7500P,
WIZnet iMCU, cortex-M0.  WIZ750SR is the protocol converter that transmits
the data sent by serial equipment as TCP/IP data type, and converts back
the TCP/IP data received through the network into serial data to transmit
back to a serial equipment.

It supports the serial interface of TTL, RS-232, RS-422/485.
