RS232/422 IN/OUT Serial network
RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the com-
munication path between two devices using either DB-9 or DB-25 connectors. This standard is used for relatively
short-range communications and does not specify balanced control lines. RS-232 is a serial control standard with a
set number of conductors, data rate, word length and type of connector to be used. The standard specifies component
connection standards with regard to computer interface. It is also called RS-232-C, which is the third version of the
RS-232 standard, and is functionally identical to the CCITT V.24 standard. Logical ’0’ is > + 3V, Logical ’1’ is < - 3V.
The range between -3V and +3V is a the transition zone.
RS422
An EIA serial digital interface standard that specifies the electrical characteristics of balanced (differential) voltage,
digital interface circuits. This standard is usable over longer distances than RS-232. This signal governs the asyn-
chronous transmission of computer data at speeds of up to 920,000 bits per second. It is also used as the serial port
standard for Macintosh computers. When the difference between the 2 lines is < - 0.2V that equals with a logical ’0’.
When the difference is > +0.2V that equals to a logical ’1’..
