RS-232 A standard interface approved by the Electronic Industries Alliance (EIA) for
connecting serial devices.
RS-422 A standard interface approved by the Electronic Industries Alliance (EIA) for
connecting serial devices, designed to replace the older RS-232 standard because it supports
higher data rates and greater immunity to electrical interference.
RS-485 An Electronics Industry Alliance (EIA) standard for multipoint communications.
SConfigurator A proprietary graphical program used to configure and update the
firmware of edge devices.
Serial Port An interface that can be used for serial communication, in which only one bit
is transmitted at a time. A serial port is a general-purpose interface that can be used for
almost any type of device.
SSL (Secure Sockets Layer) A commonly used protocol for transmitting private documents
via the Internet. SSL works by using a public key to encrypt data that is transferred over the
SSL connection. The SSL protocol secures the following data: I/O, serial port, and VSIP
communication; it does not apply to audio and video transmission.
TKIP (Temporal Key Integrity Protocol) A security protocol used in the WPA authentication
method.
TLS (Transport Layer Security) A cryptographic protocol that provide secure
communications on a wireless network.
Transceiver (Transmitter/Receiver) A device that both transmits and receives analog or
digital signals.
Transmitter A device sending video signals captured with a connected camera to a
receiver. The transmitter converts the analog signal into a digital form before transmitting
it. Also called encoder.
TTLS (Tunneled Transport Layer Security) A cryptographic protocol that creates a secure
TLS tunnel.
VSIP (Video Services over IP) A proprietary communication protocol for sending
messages between a computer and a Nextiva edge device, or between two devices.
WAN (Wide Area Network) A computer network that spans a relatively large geographical
area. Typically, a WAN consists of two or more local area networks (LANs).
WEP (Wired Equivalent Privacy) A security protocol for wireless local area networks
(WLANs) defined in the 802.11b standard. It is designed to afford wireless networks the
same level of protection as a comparable wired network.
Wireless Bridge A link between two networks, wired or wireless.
Wireless Cell A group of wireless devices that communicate together on the same radio
frequency channel and share the same wireless passkey.
Wireless Transmission A technology in which electronic devices send information to
receivers using radio waves rather than wiring.
WPA (Wi-Fi Protected Access version 1) An authentication method to secure wireless
systems. It is the successor of WEP. WPA implements the majority of the IEEE 802.11i
standard.
