SIP. Session Initiation Protocol (SIP) is a signaling communications protocol, used for controlling multimedia communication
over Internet Protocol (IP) networks.
SMA. SubMiniature version A connectors are semi-precision coaxial RF minimal connector interface for coaxial cable.
Soft Reset. See Warm Boot.
SPP. Serial Port Profile profile is a protocol that emulates a serial cable to provide a simple substitute for existing RS-232.
SSI. Serial Peripheral Interface bus is a synchronous serial data link that operates in full duplex mode. Devices communicate
in master/slave mode where the master device initiates the data frame.
SVGA. Super Video Graphics Array is an extension to the VGA standard display resolution.
T
TCP/IP. (Transmission Control Protocol/Internet Protocol) A communications protocol used to internetwork dissimilar
systems. This standard is the protocol of the Internet and has become the global standard for communications. TCP
provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end.
UDP is an alternate transport that does not guarantee delivery. It is widely used for real-time voice and video
transmissions where erroneous packets are not retransmitted. IP provides the routing mechanism. TCP/IP is a routable
protocol, which means that all messages contain not only the address of the destination station, but the address of a
destination network. This allows TCP/IP messages to be sent to multiple networks within an organization or around the
world, hence its use in the worldwide Internet. Every client and server in a TCP/IP network requires an IP address, which
is either permanently assigned or dynamically assigned at startup.
Telnet. A vehicle computer emulation protocol commonly used on the Internet and TCP/IP-based networks. It allows a user
at a vehicle computer or computer to log onto a remote device and run a program.
Tolerance. Allowable deviation from the nominal bar or space width.
Transmission Control Protocol/Internet Protocol. See TCP/IP.
U
UDP. User Datagram Protocol. A protocol within the IP protocol suite that is used in place of TCP when a reliable delivery
is not required. For example, UDP is used for real-time audio and video traffic where lost packets are simply ignored,
because there is no time to retransmit. If UDP is used and a reliable delivery is required, packet sequence checking and
error notification must be written into the applications.
USB. Universal Serial Bus is an industry standard that defines the cables, connectors and communications protocols used
for connection, communication, and power supply between devices.
V
VC. Vehicle Computer.
