10 Base-T

An older flavour of Ethernet that is slower (10 MBits per second) than the 100 Base-T used by Hog components. If connected to other equipment that only supports this flavour, then Hog components will automatically detect this, and run their Ethernet connections at this slower speed.

See Also 100 Base-T.

100 Base-T

A flavour of Ethernet that supports data rates of up to 100 MBits per second. All Hog components support this flavour of Ethernet, and comply with all relevant standards, so networking equipment designed for 100Base-T should be compatible with the Hog.

See Also 10 Base-T.

A

abstraction layer

Hog 4OS separates (‘abstracts’) the user from the details of how fixtures work. For example, most values are expressed in real world values such as degrees of rotation, rather than DMX values.

aggregate fixtures

when two or more fixtures are assigned dotted user numbers with the same whole number portion (1.1, 1.2, 1.3, etc...)

B

blocking cue

A blocking cue prevents changes made to earlier cues from tracking through to later cues.

See Also tracking.

buddying

During fanning, buddying keeps fixtures in ‘gangs’ that all take the same parameter value.

See Also fanning.

button

An on-screen control operated by clicking with the mouse or trackball or touching the screen. In this manual the work "key" is reserved for hardware buttons on the console's front panel.

C

cell

A single rectangle in a spreadsheet, containing a value.

See Also spreadsheet.

chase

See Also programmer.

compound fixture

a single fixture entity that is comprised of one or more fixture parts (sometimes of varying fixture types).

conversion curve

A curve that defines the relationship between the plotted parameter value and the DMX value sent to the dimmer or fixture. Conversion curves are like dimmer curves or profiles on other consoles, and should not be confused with paths. Conversion curves are properties of the fixture, while the path is a property of a cue.

See Also path .

crossfade

A transition between two cues, one replacing the other.

cue

A look on stage, achieved through the manipulation of fixture parameters recorded as part of a cue list. A cue requires a trigger, either manual or automatic, and has attributes such as fade, wait and delay times.

See Also scene, fade time, wait time, delay time.

cuelist

A group of cues that run in a specific order consecutively, or even simultaneously. These may be automatically linked to form a chase, or manually triggered. A cuelist is run from a master.

D

dbo

default value

A parameter value which has not been adjusted by the user. This value is assigned by the fixture's Library, and may not always be zero. For example, the default value of Shutter Open/Strobe Off may be Open.

See Also touched value, tracking.

delay time

The time the console waits before starting a cue's crossfade.

See Also wait time, crossfade, path .

desk channel

Single conventional lights that only have intensity control via a dimmer are defined as desk channels by Hog 4OS. By contrast, automated lights are referred to as fixtures.

DHCP

Dynamic Host Configuration Protocol is a way for a computer to ask a master computer on a network to assign it an IP address when it connects. Many existing networks are configured this way, and Hog 4OS supports this system. You should talk to the administrator of the network you want to connect to find out more.

See Also ethernet, IP address.

dimmer curve

See conversion curve.

directory

A window which displays palettes, scenes or groups.

See Also palette.

DMX

Short for DMX 512, DMX is the communications protocol most commonly used to connect lighting consoles to fixtures and dimmers.

DMX address

A number between 1 and 512 that identifies a controllable parameter of a fixture. Each fixture or group of dimmers has a ‘start address’, the first of the range of DMX addresses that it uses.

DMX universe

A single DMX output with 512 channels is known as one DMX universe. A Hog network may support many universes each with fixture addresses between 1 and 512.

See Also DMX Processor.

See Also buddying.

fixed kind

Fixed kinds are the default collections of functions that collectivity contain all of the fixture functions used in your show. There are 7 fixed kinds: Intensity, Position, Colour, Beam, Effects, Time, and Control. The fixed kinds are represented by dedicated front panel buttons and onscreen menus

See Also kinds.

fixture library

A data file that contains details of a fixture's parameters, required so that Hog 4OS ‘understands’ how the fixture works and what it can do. The fixture libraries are an important part of making the console's abstraction layer work.

See Also abstraction layer.

H

hard value

The output of a master running a cuelist is a mix of hard and soft parameter values. Hard values are those that are in the current cue, while soft values are those that have tracked through from previous cues.

See Also tracking.

HID Mode

A special mode for the console front panel that allows it to be used as a keyboard during a full software install. Pig + Fan+ Up Cursor Key puts the front panel into HID Mode. Pig + Fan+ Down Cursor Key takes the front panel out of HID Mode and puts it back into Hog mode.

See Also tracking.

HTP

Highest Takes Precedence. In this system of operation, the highest value assigned for a parameter is the one that applies. A fixture can be in cues on two masters, and the highest level of the two will be the one seen. HTP is only relevant to intensity parameters where the idea of ‘highest’ has meaning.

See Also LTP.

hue

The colour (pigment) element of colour notation.

See Also saturation.

I

I-Wheel

The I-Wheel on the right hand side of the console is used to control fixture intensity.

in time

The time of the fade up of the incoming cue during a crossfade. All fixtures that are increasing in intensity will come up over this time.

See Also split fade, path , fade time.

inhibitive submaster

A master that sets a maximum level on a group of fixtures. If the master is at 80%, then the fixtures will never come above 80% in the console's output.

IP address

On an Ethernet network, each Hog component has an address, called an IP address, used to identify it. You can usually use the default addresses, but if you are connecting to an existing network you may need to specify a different address, according to how your network is configured.

See Also ethernet.

K

key

A physical button on the console's front panel. The manual reserves the word "button" for buttons that appear on screen.

kinds

Kinds are collections of fixture functions organized into wheelsets. Kinds are stored in the kinds directory and exist in two different forms: fixed kinds and user kinds.

See Also fixed kind, user kind.

knockout

Knocking out is the process of removing fixtures from the Programmer window, so that they will not be recorded into cues.

L

LTP

Latest Takes Precedence. In this system of operation, the most recent instruction to assign the value of a parameter is the one that applies. A cue run on one master can take control of fixtures set by a cue in another master.

See Also HTP.

M

maintain state

The Hog 4OS's Maintain State feature eliminates the common problem with tracking, where playing back cues out of order results in incorrect lighting states on stage.

See Also tracking.

mask

A method of selecting information that is specific to a palette, fixture, cue, scene or group, when recording, making selections, editing, programming, or playing back cues/scenes. For example the fixed function kinds can be used to mask which function kinds (intensity, position, colour and beam) get record into a cue or palette.

master

"Master" is a generic term that can be used to refer to any cuelist, scene, or chase in the show. When a cuelist, scene, or chase is assigned to one of the choose keys on the console it is know as a "physical master"; otherwise it is referred to as a "virtual master".

See Also cuelist.

patch

The assignment of DMX addresses to fixtures.

See Also DMX.

patch point

The set of information that defines where a fixture is patched, including DMX address, DMX universe, and DMX Processor. Some fixtures have multiple patch points.

See Also DMX, DMX address, DMX Processor.

path

A way of defining the way that a parameter changes during a fade. You could assign a path that makes the fixture parameter snap to its final value at the start of the fade, for example. Paths should not be confused with conversion curves; paths are the properties of a cue, while a conversion curves is the property of a fixture.

See Also fade time, conversion curve.

pig key

The Pig button is a modifier key, and may be used in conjunction with other keys to alter their function.

pile on

A cue who's number contains a decimal point. Point cues are initially given whole numbers, but a point cue can be inserted between two whole number cues. For example, cue 2.5 is a point cue between cues 2 and 3.

port number

On a computer network, the port number defines a particular type of network traffic. In the case of a Hog network, each show running on the network has its own port number, so that a console can identify and connect to a particular show.

programmer

A window where cue and scene data is created or edited. The Programmer takes priority over all commands sent to a fixture elsewhere in the console.

R

rate

The adjusted speed at which a recorded cuelists, scenes, chases, and effects are played. For recorded chases rate is represented in beats per minute. For recorded cues, scenes, scenes, and effects rate is represnted in percentage. For example, a 2s cue will playback in 4s when the cuelist it is part of has a rate of 50%.

Rate Wheel

The wheel on the left hand side of the Hog 4 console and Hog 4PC used for adjusting playback and effect rates.

remainder dim

Used after selecting a fixture or group of fixtures, setting all remaining fixtures to a zero intensity level.

S

saturation

The amount of pigment in colour notation.

See Also hue.

scene

a single cue stored in the scene directory that has full timing features but does not belong to a cuelist. Scenes can be used to store a single look that may be called back for use in later programming, or to play back many simple looks directly from physical or virtual masters.

See Also cue, cuelist.

selection order

The order in which the user selects fixtures into the Programmer or editor. Hog 4OS remembers this and can apply fanning, or effects according to a fixture's place in the sequence. The sequence is recorded as part of groups and palettes.

See Also group, palette.

show server

The Hog console that ‘owns’ a show. Other consoles may join the show, but the original console that created the show will remain the show server.

slot

A discrete step in a parameter's range, such as the position of a gobo wheel.

SMPTE

A form of time code that can be used to synchronise the operation of various controllers, for example synchronising lighting to video playback.

See Also toolbar.

soft parameter value

See tracked value.

split fade

A crossfade where the incoming and outgoing cues have different times, causing an imbalanced or dipped fade profile.

See Also crossfade, in time, out time.

See Also ethernet.

T

TCP/IP

A network protocol or language that computers use to talk to each other over Ethernet. Hog 4OS uses this standard protocol, which means that it can safely be connected to other networks of computers and will not interfere with them. For show-critical situations you should run the Hog system on its own independent network.

See Also ethernet.

toolbar

A long, thin window with a series of buttons, that generally sits along the top or bottom edge of the screens. When in this position, a toolbar is said to be ‘docked’.

See Also Soft Key.

timecode

A method of synchronising the console with other playback sources, such as music, video or film. Hog 4OS supports MIDI, Linear Timecode and Video Timecode.

See Also MIDI, SMPTE.

timing

Cues have several values that control timing: fade, wait, delay and path.

See Also fade time, wait time, delay time, path .

tracked value

The output of a master running a cuelist is a mix of hard and tracked parameter values. Hard values are those that are in the current cue, while tracked values are those that have tracked through from previous cues.

See Also tracking.

tracking

A method of dealing with cuelists that does not record information in a cue unless it is a change from the previous cue. This allows multiple cuelists to be running at the same time without them interfering with each other.

See Also hard value, tracked value, touched value, default value.

U

UDP

A network protocol or language that computers use to talk to each other over Ethernet. Hog 4OS uses this standard protocol, which means that it can safely be connected to other networks of computers and will not interfere with them. For show-critical situations you should run the Hog system on its own independent network.

See Also ethernet.

user kind

User kinds are customized kinds built by the user, allowing you to create smaller collections of fixture functions on fewer wheelsets.
