HDCP
High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed byIntel Corporation to protect digital
audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI),
Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections. The specification is proprietary, and implementing
HDCP requires a license.
HEPA
High Efficiency Particulate Absorbing
IP
Internet Protocol. The network layer of TCP/IP. Required for communication with the internet.
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.
Restricted access location
A location for equipment where both of the following paragraphs apply:
1) Access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the reasons for the restriction
applied to the location and about the precautions that shall be taken.
2) Access is through the use of the tool or lock and key, or other means of security, and is controlled by the authority responsible for
the location.
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 contro
l 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, Logica
l ’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 isusable over longer d
istances than RS-232. This signal governs theasynchronous 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.
