D
default gateway
The default gateway is the device that passes network data from the local network to other
networks.
DHCP
Short for "Dynamic Host Configuration Protocol," a protocol for assigning dynamic IP
addresses to devices on a network.
Digital Remote
Digital Remote (DR) hardware devices, a variety of which are available for your HAL Sys-
tem, provide system users with easy control of volume, audio selection, preset recall, and
more—out in the locations where the control is needed.
DNS
Short for Domain Name System, DNS is a directory service that translates domain names or
host names into IP addresses.
Downstream
Audio channels on the expansion bus that flow away from the HAL device.
F
FireWire
A form of connectivity similar to USB, meant to connect peripherals such as MP3 Players
and digital cameras to the computer. Legacy HAL Systems used FireWire to connect EXP1
units to the HAL1 device. FireWire operates around 30 times faster than a USB 1.1 con-
nection. FireWire is technically known as IEEE-1394.
I
Inverted option
An option for a Toggle link participant that, when selected, reverses the behavior of the Tog-
gle control with respect to the link value. When the link's value is true, the participant's value
is false (and vice versa).
L
Level
Generally associated with volume, Level controls have a continuous series of states that are
represented by a slider.
