OG-12GM openGear Card v1.0.2r1 24 www.aja.com
Quad Link (SDI 1-
4) - Causes the OG-12GM to use SDI Outputs 1-4, if possible.
The combination of input and output settings determines whether the
OG-12GM is muxing, demuxing or passing through.
Output Mapping
NOTE: Output pixel mapping applies only to 4K/UltraHD signals being transported on
Quad Link 4x 3G outputs. 6G and 12G SDI are always Two Sample Interleave (2SI),
and Quad Link 1.5G SDI is always Square Division (Quadrant).
Selects the output mapping for Quad Link 4x 3G outputs. Choose from the
following:
Auto -
Automatically selects the output pixel mapping based on the input pixel
mapping detected.
If Quad Link UltraHD/4K (SDI 1-4) 2SI is detected on the input, the output pixel
mapping will be SQD.
If Quad Link UltraHD/4K (SDI 1-4) SQD is detected on the input, the output
pixel mapping will be 2SI.
If Quad Link UltraHD/4K (SDI 1-4) SQD or 2SI 3G is detected on the input, the
output pixel mapping will be 12G 2SI.
If Single Link UltraHD/4K (SDI 1-4) 12G is detected on the input, the output
pixel mapping will be Quad 3G 2SI.
2SI -
Causes the OG-12GM to output a Two Sample Interleave (2SI) pixel mapped
signal.
SQD -
Causes the OG-12GM to output a Square Division (Quadrant) pixel mapped
signal.
3G-SDI Mode
The OG-12GM's 3G-SDI Mode offers the choice between Auto, Level A and Level
B-DL.
Auto -
The OG-12GM will automatically select Level A or Level B-DL based on the
inputs detected.
• For Single Link 12G input, Auto will select 4x 3G Level A for the output.
• For a Single Link 6G input, Auto will select 4x 1.5G for the output.
• For a Single Link 3G Level A input, Auto will select 2x 3G Level B-DL for the
output.
Level A -
The SDI Outputs will carry a 3G-SDI Level A signal to support these
configurations:
• 4x 3G-SDI Level B-DL to 4x 3G-SDI Level A
• 1.5G-SDI to 3G-SDI Level A
Level B-
DL - The SDI Outputs will carry a 3G-SDI Level B-DL signal to support
these configurations:
• 12G-SDI to 4x 3G-SDI Level B-DL
• 4x 3G-SDI Level A to 4x 3G-SDI Level B-DL
• 3G-SDI Level A to 1.5G-SDI
DA Function
The OG-12GM's Distribution Amplifier (DA) function is available for Single Link
output signals.
On -
When turned on, the DA function will duplicate SDI Output 1's signal on SDI
Outputs 2, 3, and 4.
NOTE: If the output is a Quad Link signal, the DA function is overridden and turned off.
