Integrating GSP-1620 Modems into OEM Products

The Control port is “enabled” by asserting DTR on the Control port.

In case of a reboot (due to fatal errors or any other reason), the DSR line will be set inactive so that the user application can detect a reset condition and take the necessary action.

Data Port Signals

The Data port (DP) is a hardware-flow controlled, RS-232 level, asynchronous serial interface:

•The Data port uses the following RS-232 leads for operations: Transmit Data (TxD), Receive Data (RxD), Clear To Send (CTS), Data Terminal Ready (DTR), Data Set Ready (DSR), Ready to Send (RTS), Data Carrier Detect (DCD), Ring Indicator (RI), and Signal Common (GND).

•The format for data on the Data port is 8 bits, no parity and 1 stop bit.

•The baud rate is user-configurable to selected rates from 300 bps to 115.2 kbps. The baud rate is adjustable in software.

•In case of a reboot (due to fatal errors or any other reason), the DCD and DSR lines will be set inactive so that the user application can detect a reset condition and take the necessary action.

•Functionally, the Data port integrates AT commands and alert messages as well as application data traffic.
