3.SERIAL COMMUNICATION




Data Communication

Parallel Serial



Parallel Communication:• Transfer of number of bits simultaneously.

Serial Communication:• Transfer of single bit at a time.



SERIAL COMMUNICATION• Serial data transfer suitable for long distance data transfer.

• Serial communication is cheaper as single data line is used.



SENDER RECEIVER

SIM 300 GSM MODEM



SIM300 key features • Power supply Single supply voltage 3.4V – 4.5V • Power saving Typical power consumption in SLEEP mode to 2.5mA

• Frequency bands SIM300 Tri-band: EGSM 900, DCS 1800, PCS 1900. The band can be set by AT COMMAND, and default band is EGSM 900 and DCS 1800.

• SMS storage: SIM card



SIM300 Hardware Interface Description



PIN NAME I/O DESCRIPTION• DTR I Data Terminal Ready

• RXD I Receive Data • TXD O Transmit Data • RTS I Request to Send • CTS O Clear to Send

DB9 CONNECTOR



Features

• Adds one USB serial port by connecting to the RS232 DB9 footprint of a device

• Easy placement for an standard Male and Female RS232 DB9 footprint of a device

• A selection of RS232, 3.3V or 5V UART signal levels.

• 128 byte transmit buffer, 256 byte receive buffer

• UART data signals: TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, GND



MAX 232



RS232 VOLTAGE LEVELS• Logic 0 :- +3 V to +25 V

• Logic 1 :--3 V to -25 V
