OBJECTIVES:
To demonstrate basic operation of a FSK data modem (9600 Baud rate) with RS232 interface with two pc using LAB modem software .
System requirements:
Pentium compatible processor
Operating system: Windows XP
Interface: RS232 connector.
CD-ROM drive.
COM port DB-9 pin .
INTRODUCTION:
Lab modem trainer is a very competent trainer. You can Send and receive data Using a single computer. Modems are not needed to connect two compatible digital devices directly; the transmission never needs to cross analog lines, such as telephone lines, But you do need an interface to handle the exchange (readiness establishment, data transfer, receipt, etc.), just as an EIA-232 DTE-DCE cable does. The solution, provided by the EIA standard, is called a null modem. This circuit implements a simple FSK modem, consisting of both the frequency shift keying modulator a corresponding demodulator
