3.5 Serial interfaces

MC45 offers two serial interfaces, each operating at 2.65V level. All RS-232 signals on the
board-to-board connector are low active. Both interfaces are implemented as a serial
asynchronous transmitter and receiver conforming to ITU-T RS-232 Interchange Circuits
DCE.

The GSM engine is designed for use as a DCE. Based on the conventions for DCE-DTE
connections it communicates with the customer application (DTE) using the following
signals:

RS-232(0)

·

Port /TXD @ application sends data to the module’s /TXD0 signal line

·

Port /RXD @ application receives data from the module’s /RXD0 signal line

RS-232(1)

·

Port /TXD1 @ application sends data to module’s /TXD1 signal line

·

Port /RXD1 @ application receives data from the module’s /RXD1 signal line
