  • Page 7: Introduction

    This module enables remote gauging, remote management of the device through the network based on the Ethernet and the TCP/IP by connecting to existing equipment with RS-232 serial interface. In other words, WIZ127SR is a protocol converter that transmits the data sent by serial equipment as TCP/IP data type or vice versa.
