Quick Overview

Two port serial to Ethernet module with TTL level and W7500


Product Description

WIZ752SR-120 is an embedded module based on WIZnet W7500 & IP101GRI. WIZ752SR-120 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 the equipment. It supports two serial ports(3.3V LVTTL) so that it can communicate with two serial pieces of equipment at the same time. It is a direct replacement for the WIZ120SR - they are pin compatible and can be used in the WIZ120SR-EVB. In addition to the well-known pins from the WIZ120SR 4 GPIOs are added which can be freely controlled as analog input or digital in-/output.
