6. External interfaces
This unit comes with RS-4, GPI and tally connectors to serve as external interfaces.
6-1. RS-422 connector
This enables the unit to be controlled by an editing controller AG-A850. 
Use it with the settings below.
Baud rate:  38400 bps
Parity :  ODD
Stop bit:  1 bit

6GROUNDGround
7TXD +Send data (+)
8RXD –Receive data (–)
9FRAME GROUNDFrame ground
The following lists the functions which can be controlled by AG-A850. (Compliant with the GVG protocol)
• Crosspoint switch
• Wipe pattern selection
• Transition mode (MIX/WIPE) selection
• Auto transition time setting
• Auto transition execution
If the [AUX] switch is pressed twice, the lamp of the switch will light up red. 
While the lamp is lighted up red, control exercised from an external source can be canceled. 
If the same switch is pressed twice again while its lamp is still lighted up red, the\
 lamp is extinguished, and the 
control exercised from an external source is re-established.
6-2. GPI connector
This enables auto take operations to be executed by an external device.
Auto transitions are executed at the fall of the GPI signals.
The signals are input using contacts. The auto take operations are 
executed using these contacts as triggers.
Use an M3.5 stereo plug for connection with the main unit.

Appendix (glossary)
Defined below are the terms used in this manual.
WordExplanation
AB Bus systemA bus control mode. By executing a transition, the A bus and B bus signals are 
output to the program images alternately.
Ancillary DataThe auxiliary data other than the video signals which is transmitted inside the 
data stream of the video serial interface. The data superimposed on the vertical 
blanking period is referred to as the V ancillary data (VANC).
Aspect ratioThe ratio between the horizontal and vertical dimensions of an image or screen. 
It is 16:9 for the HD format and 4:3 for the SD format.
AUX
[Auxiliary Bus]
A spare bus which can be switched by signals other than the main line output 
signals.
AVDL
[Automatic Video Delayline]
A function to automatically adjust the input image signal phase to the h\
orizontal 
synchronization reference signal phase.
BB
[Black burst]
The black burst signal. A full-screen black level composite signal which is used 
as the reference signal for gen-lock.
BorderThe area or margin that is added to the edge of a wipe or key.
Its width and color can be adjusted. The defocusing of the area around a border 
is referred to as the soft effect.
ClipThe threshold level of the luminance when key signals are created from a key 
source.
Color BackgroundThe signals which are output from the internal color generator and used as the 
background image.
DensityA parameter which is used to adjust the density of the key signals.
DVI 
[Digital Visual Interface]
A digital video interface standard.
DVI-I can handle both digital signals and analog signals.
EthernetA computer network standard; the 10BASE-T (10 Mbps), 100BASE-TX 
(100 Mbps) or other such standard based on the transmission speed.
Flip Flop system
(PGM/PST system)
A bus control mode. The signals selected by the program bus are always output 
as the program images. By executing a transition, the program bus and preset 
bus signals are switched over.
Frame MemoryA memory which can hold the video signals equivalent to one frame.
Frame SynchronizerA function which enables the asynchronous video signal input to be switched.
FreezeA function which continues the display of the same image, creating the 
impression that the image has been “frozen”.
GainA parameter which adjusts the defocusing of the edges of the key signals.

WordExplanation
GenlockA function for synchronizing the video signals using an external sync signal as 
the reference.
GPI
[General Purpose Interface]
Interface signals which control auto transition from an external source.
IREA unit used for video signal levels.
The setup level (black level) of the signals is expressed as 0 IRE, 7.5 IRE, etc.
HueThe color tone of the video signals.
Key EdgeThe border or shadow added to the edges of keys.
Key FillThe signal that uses key combination processing to fill in the areas left blank by 
the key signals.
Key invertA function which inverts the key signals.
Key SourceThe video signals for creating the key signals.
Linear KeyThe function which combines keys using monochrome key signals with 
gradations in its outlines as a reference.
Lum
[Luminance]
The brightness portion of the video signals.
Luminance KeyThe function which creates key signals based on the luminance (brightness) 
information of the video signals to combine keys.
ME
[Mix Effect]
A video effect device which combines a number of video signals to create mix, 
wipe, key and other video signals.
MixThe picture-changing effect produced by overlapping one image with the next. 
It is also referred to as “dissolve”.
PVW
[Preview]
The function for checking ahead of time the image which will be output after the 
next transition. The image is output from the PVW system.
PGM
[Program Bus]
The bus which always carries the program output signals.
PST
[Preset Bus]
The bus which carries the program output signals after the next background 
transition.
Preset MemoryThe memory in which the control panel statuses can be saved and recalled. 
The switch selection statuses as well as the border, color and other setting 
information can be saved in this memory.
RS-422A serial interface standard. It is the interface used to control the switcher from 
an editor or other external device.

WordExplanation
SDI
[Serial Digital Interface]
The standard by which video signals in various SD and HD formats are 
transmitted along a single coaxial cable.
