3GM v1.5

Installation
In normal operation the 3GM uses between 4 and 6 watts of power. Because it is
designed to use the outer case and the attached cables for heat dissipation, the case can
feel warm to the touch. This is normal. Although the 3GM has been tested for proper
operation in an ambient temperature up to 45 degrees Celsius (113 F), it is recommended
to not position the 3GM in close proximity to other warm surfaces or airflow.
To install, connect BNC cables to the desired source and destination devices and apply
power to the converter (AJA power supply included).
5
MON TYPE:
Linear or
log color
LIN:
Configure input video as linear color.
Will colorspace convert and resample as
needed.
LOG:
Configure input video as logarithmic color.
Will perform a 10-bit Cineon to 8-bit linear
conversion before colorspace converting and
resampling the monitor output.
Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.
6
MON RNG:
SMPTE or
Full range
color values
SMPTE:
Defines input video as SMPTE color range
(040h-3ACh).
FULL:
Defines input video as FULL color range (004h-
3FBh).
Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.
7
MON SEL:
Video or Key
for Monitor
output
VID/A:
For video input with an Alpha channel, this
sets the monitor output to Video in the case of
4:4:4:4 video input.
For video input without an Alpha channel, this
sets the monitor output to be Link A.
KEY/B:
For video input with an Alpha channel, this sets
monitor output to the Alpha (key) in the case of
4:4:4:4 video input.
For video input without an Alpha channel, this
sets the monitor output to be Link B.
Note: Switches 5, 6, and 7 only affect the monitor output. This switch has no effect on the
primary outputs.
8
INP MODE:
Automatic
or Manual
Setup
AUTO:
If payload ID is present, the 3GM uses data
from the payload ID information to set color
space and bit depth (switches 3 and 4).
If payload ID is not present, the 3GM reverts to
switches 3 and 4 for input information.
MAN:
The 3GM uses switches 3 and 4 for color space
and bit depth, regardless of whether payload
ID is present or not.
