Glossary
MAC address
Media Access Control address. Unique hardware number, used in combination with the IP-address to connect to the network (LAN
or WAN).
PiP
PiP stands for "Picture in Picture" and allows to display multiple windows containing each of them an image. The windows may be
of the video or data type.
Projector address
Address installed in the projector to be individually controlled.
Qualified (service) technician
Persons having appropriate technical training and experience necessary to be aware of hazards to which they are exposed in per-
forming a task and of measures to minimize the danger to themselves or other persons.
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.
