4.4 COM – Serial Interface
The complete serial interface RS-232C on a 9-pin connector is identical with any
external modem.
The transmission rate ranges from 1200 to 115200 bps (2N® SmartGate supports
autobauding, i.e. responds to an AT command at a rate identical with the AT
command transmission rate, and retains set on this rate). The transmission setup
must be 8 bits, no parity and one STOP bit (8N1).
SmartGate‟s central processor uses the same interface for establishing calls and so
it must have the possibility to block an external serial interface - all PC SW must
provide transmission hardware flow control (HW handshaking).
COM can be used for

Programming and monitoring;

CSD PC-PC data transmission;

CSD or high-speed GPRS connection to the Internet;

SMS sending and receiving.
Programming, Monitoring
Install the 2N® SmartGate PCManager software available on the included CD-ROM
into your PC.
The program is designed for 2N® SmartGate parameters programming. It can read
configuration data from the memory and store them in SmartGate. Moreover, all
parameters can be saved in your PC file for backup or saving into another 2N®
SmartGate system.
The 2N® SmartGate PCManager contains an easy monitoring tool too. With this
tool you can identify the GSM provider‟s name, signal strength, GSM module, SIM
card, and so on during 2N® SmartGate operation.
