WebRS-485 is an industrial specification that defines the electrical interface and physical layer for point-to-point communication of electrical devices. The RS-485 standard allows for long cabling distances in electrically noisy environments and can support multiple devices on the same bus. When, Why, and Where to Use RS-485 WebIn RS232 specification low level -3v to-15v is defined as logic ‘1’ is ON state and referred as ‘Marking’ while high level +3v to +15v is defined as logic ‘0’ as OFF state and known as ‘Spacing’. The RS232 standard also limits the maximum slew rate which reduces the cross-talk between the two signals.

WebParity has many settings, NONE, EVEN, ODD, MARK and SPACE. 2.2.4 Number of Stop Bits The number of stop bits usually varies between 1, 1.5 and 2. 2.3 Flow control Flow control is used to control the flow of data and prevent buffer overrun if a device cannot accept more data. It is also sometimes termed as handshaking. http://www.rs485.com/rs485spec.html

The RS232 specification governs the physical and electrical characteristics of serial communications. This specification defines several additional signals that are asserted (set to logical 1) for information and control beyond the data signals and signal ground. See more Serial communication is basically the transmission or reception of data one bit at a time. Todays computers generally address data in bytes … See more When transmitting a character there are other characteristics other than the baud rate that must be known or that must be setup. These characteristics define the entire interpretation of … See more When transmitting a byte, the UART (serial port) first sends a START BIT which is a positive voltage (0), followed by the data (general 8 bits, but … See more The second characteristic is parity. The parity characteristic can be even, odd, mark, space, or none. If even parity, then the last data bit transmitted will be a logical 1 if the data transmitted had an even amount of 0 bits. … See more

The terms derive from the early days of the electric telegraph system, where the marking state would cause a mark to be output on paper, and the spacing state would create no mark.
