WIZ750SR
WIZ750SR
WIZ750SR is a compact sized serial to Ethernet module using the W7500P Ethernet MCU (SoC based on ARM Cortex-M0 architecture).
WIZ750SR 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. It complies with Commercial temperature standard range(0°C ~ 70°C) and supports all relevant serial interface systems (TTL / RS-232 / RS-422/485).
WIZ750SR is compatible with the WIZnet WIZ107/108SR S2E module. In addition, WIZ750SR contains an 4-pin GPIO expansion port that can be controlled freely by the user. (analog input or digital in/out)
WIZ750SR is the best fit solution to control user's serial device via Ethernet network.
