RS232 cable is used to transmit communication signals or data between a computer and an electric device through a serial communication port. The Value of RS232 Cable RS232 cable is one that is used to transmit communication signals or data between a computer and an electric device through a serial communication port. The particular serial ports to be used depend on the intended point of connection. RS232 cable is particularly used for connections, where there is use of a single binary ended connection. Many large machines that are connected to computers depend hugely on this type of data transition to enable communication between the device and the computer. For a person who has no prior knowledge of such cables, it might be challenging to select the most suitable RS232 cable from a range of similar cables on display. There are male and female connectors under this type of cable. So in order to identify the correct RS232 cable, one must be aware of the kind of port on the computer. The capacitance of RS232 cable also plays a vital role in data transition through it. The RS232 cable with low capacitance will have long transmission of data. Various data ranges are recommended for certain lengths of RS232 cables. RS232 cable with a length of 60m has a data transfer rate of 2400bps; RS232 cable with a length of 30m transmits data at a rate of 4800bps; RS232 cable with a length of 15 transmits data at a rate of 9600bps and RS232 cable with a length of 7.6 transmits data at a speed of 19200. This data clearly shows that the shorter the cable and lower the resistance, the faster is the transmission rate. Therefore the specifications and recommendations of the manufacturer also play a vital role in the selection of RS232 cable. A RS232 cable baud rate is the number transmission change, wave strength changes or signal event it makes, to the transmission point per second using a signal that is managed digitally. It is measured in ‘Baud’ or ‘symbols per second’. RS232 cable provides that for a compliant port; signal characteristics for a capacitive load of 2,500pF must be provided if it is to function properly. It is therefore right to say that this does not correspond to a fixed RS232 cable length since different RS232 cables have different characteristics. It will be a good advice not to use this kind of cable, especially where longer connections of more than 60 metres are required, because its transmission is affected by noise that limits the transmission of higher number of bits per second, which may result to loss of data during the transmission. To avoid loss of data in this RS232 cable or damage of RS232 cable, do not remove the cable if the device is on. Always keep the cables away from radio waves and always pick short cables. Remember to keep the cable fixed to the machine so that if someone accidentally knocks it, it doesn't fall off. By looking at these conditions together with the recommendations of the manufacturer, one would definitely make a right decision in picking the best cable from the market.
