Glossary

U

UDP

user datagram protocol. A connectionless mode protocol in which messages are delivered in a datagram to a destination computer. The UDP protocol is typically bundled with the Internet Protocol (UPD/IP).

V

varistor	A two-electrode semiconductor device with a voltage-dependant nonlinear
	resistance that drops markedly as the applied voltage is increased. It is used to
	suppress transient voltage surges.
voltage group	A grouping of Advantys STB I/O modules, all with the same voltage requirement,
	installed directly to the right of the appropriate power distribution module (PDM) and
	separated from modules with different voltage requirements. Never mix modules
	with different voltage requirements in the same voltage group.

W

watchdog timer A timer that monitors a cyclical process and is cleared at the conclusion of each cycle. If the watchdog runs past its programmed time period, it generates a fault.
