3.SERIAL COMMUNICATION

PRESENTED BY:
BODHE PRASHANT A.


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

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.
