**INTRODUCTION**

Tcp-232-v4 is a communication module for transparent data transmission between Ethernet and serial port (TTL). The RJ45 network port of the module adopts the external connection method, so users can easily embed it into their own products. At the same time, the module has the characteristics of small size, high stability, strong anti-interference ability and so on, which is suitable for industrial environment application.
