2.1. Basic Integration
The modem supports asynchronous serial communication known as RS-232.
This chapter describes the basic integration and communication of MT2 with TE2. MT2 hereby
defines and TE2 means host products which can issue AT commands and handle the response
through UART or RS-232 signalling. The popular examples of TE2 are PC’s, PDA’s and unmanned
systems such as Data Loggers, RTU’s or PLC’s.

2.2. Serial Interface
TE2’s command and MT2’s response pair is the basic interface sequence. The pairs should keep a
pre-defined format and ignore the case of letters unless otherwise specified. Supports 2 serial
interfaces, UART1 and UART2. UART1 serves an AT command set with ASCII character sequence
and UART2 as a factory diagnostic port, serves an AT command with Async-HDLC format.
