RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the
communication path between two devices using either D-SUB 9 pins or D-SUB 25 pins 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 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 asynchronous 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'..
Subnet mask
A number that is used to identify a subnetwork so that IP addresses can be shared on a local area network.
Transport latency
The added delay in the image processing chain. The value is the number of lines relative to the output
resolution.
