3.3 RJ45 Connector
The RJ45 Modular COM port is used to supply power to the terminal as well as provide serial data
communication. The terminal accepts voltage levels b5Vdc to +32Vdc. Do not exceed these
levels. The minimum requirement, for the terminal to communicate with the application or DTE, is
established through using the following pins:
TxD: Where the Application sends data to MLiS Terminal
RxD: Where the Application receives data from MLiS Terminal
