The Utility of RS232 Cable
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. These cables are 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 one from a range of similar cables on display. So in order to identify the correct cable, one must be aware of the kind of port on the computer.
The capacitance of such cables also plays a vital role in data transition through it. The RS232 cable with low capacitance will have long transmission of data. For instance, a 60m long cable has a data transfer rate of 2400bps; a 30m cable transmits data at the rate of 4800bps and a 15m long cable transmits the same data at the rate of 9600bps. This 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 selecting an appropriate cable. Cable 'baud rate' is defined as the number of wave strength changes to the transmission point per second using a signal that is managed digitally. It is measured in 'Baud' or 'symbols per second'. RS232 cables provide 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 cable length since different 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 meters 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 the loss of data in such cables 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.
