#Rs232C Cord Serial Port Used#

The transmit and receive pins for the schematic are determined by the gender of the RS232 cable.USB Cables / IEEE 1394 Cables USB to RS232 Embedded Converter, 10cm. The circuit receives power from the TTL end of the cable and takes the 3.3V / 5V TTL signal and converts it to the RS232 signal. The converter cables are based on the MAX232 RS-232 converter from Texas Instruments.

For this method you will need the MAX232 chip (or equivalent) connected as shown in the circuits to decode/encode the RS232 signal levels for the PICs. Since RS232 voltage levels are generated it will allow operation over long cables. A cable wired for connecting two DTEs directly is known as a null modem cable.The RS232 unit provides all RS232 signals (between +-3V to +/-12V) and will plug into the MAX232 device. The form of connectors depends on the particular serial port used.

LapLink cable (can be seen as a parallel equivalent to a serial null modem cable) Other serial communications standards are better adapted to drive hundreds or thousands of metres of cable.Wikibooks has a book on the topic of: Serial Programming:RS-232 Connections Empirically tested combinations of bit rate, serial ports, cable type, and lengths may provide reliable communications, but generally RS-232-compatible ports are intended to be connected by, at the most, a few tens of metres of cable. This does not correspond to a fixed length of cable since varying cables have different characteristics. The RS-232 standard states that a compliant port must provide defined signal characteristics for a capacitive load of 2500 pF.
