Device
Each video input device must have a unique device number allocated to it. This
Number
device number is unique with respect to the other video inputs of the same type and
does not relate to the video input reference number (REF) or its physical connection
to the video system.
Definitions in the video input DEVICE TYPE and DEVICE NUMBER fields allow exact
selection of the video input device from a keyboard. The valid range for device
numbers is 1 – 9999.
Enter the desired device number and press Enter on the keyboard.
Source
A source group is a group of video input devices (cameras, VCR's etc.) that are
Group
linked together as specific access groups. This allows the system to control which
video output channels have access to which video inputs. Due to hardware
restrictions, some monitors may only be able to access certain video inputs. Source
groups are also used to partition video input selections for specific operators.
A source group number is allocated for every video input. The default source group is
0, the range of allowable source groups is 0 – 99.
Enter the desired source group number and press Enter on the keyboard.
Device
This is an 18-character description used to identify the selected video input device. It
Description
is displayed on a monitor (or other video output channel with text insertion) whenever
the video input device is selected. It is also used by video fail alarms to identify the
failed video input device.
Enter the desired description (up to 18-characters) in the field and press Enter on the
keyboard.
Primary
This is the address of the subrack to which the video input is physically connected.
Subrack ID
Valid primary subrack addresses range from 1 – 99. A value of '0' indicates that no
video switching will occur when the device is selected (often used where a device
needs to be selected by a keyboard for control purposes, but where no video
switching is required).
Enter the address of the subrack and press Enter on the keyboard.
For Videoblox Subrack, this ID represents the 'V'+communication port number to
which the VideoBlox analog video input cards are connected. Valid primary subrack
addresses range: 'V'+maximum communication ports. Suffix 'A' with primary subrack
ID (e.g., V1A) indicates that the audio is enabled for that particular video input.
Input
This is the physical connection point on the primary subrack. The valid range for the
Number
video input number is 1 - 128. Certain subrack types have fewer than 128 video
inputs.
HMX1132 - maximum video input number is 32.
HMX32128 HD-Series subrack .. up to the maximum 128.
Enter the video input number on the subrack and press Enter on the keyboard.
For VideoBlox Subrack, this is the physical input location of the video input channel.
The valid range for the VideoBlox is 1 - 4096.
For input numbers 1 to 16 – the input card address is 0.
For input numbers 17 to 32 – the input card address is 1.
