Genicom RS-232 Serial Interface
Part #: 043278
Summary
The RS-232 serial interface protocol was designed to allow the transmission of computer data over standard telephone lines. This is accomplished by standardizing computer data into 8 bit data bytes. The RS-232 interface will put a start bit at the front of the byte and a stop bit at the rear of the byte to indicate a complete character to the receiving device. These 8 bit bytes are disassembled into1 start bit, 8 separate data bits and stop bit, which are transmitted via modem and phone line to a receiving device which assembles the 10 bits back into an 8 bit data byte after stripping off the start bit and the stop bit. The receiving device either prints or stores the 8 bit data byte dependent upon the receiving device. The RS232 interface is able to run up to 115.2 KBaud. This enables an easy connection to the host PC with medium data transmission rates. For the download of large applications, an optional high-speed interface is recommended.
