TX Video Configuration
Peak bandwidth limiter percentage
The TX unit will employ a ‘best effort’ strategy in sending video and other data over the IP network. This means
it will use as much of the available network bandwidth as necessary to achieve optimal data quality, although
typically the TX unit will use considerably less than the maximum available. In order to prevent the TX unit
from ‘hogging’ too much of the network capacity, you can reduce this setting to place a tighter limit on the
maximum bandwidth permissible to the TX unit. Range: 0 to 95%.
Background Refresh
The TX unit sends portions of the video image only when they change. In order to give the best user
experience, the TX unit also sends the whole video image, at a lower frame rate, in the background. The
Background Refresh parameter controls the rate at which this background image is sent. The default value is
‘every 32 frames’, meaning that a full frame is sent in the background every 32 frames. Reducing this to ‘every
64 frames’ or more will reduce the amount of bandwidth that the TX unit consumes. On a high-traffic network
this parameter should be reduced in this way to improve overall system performance. Options: every 32 frames,
every 64 frames, every 128 frames, every 256 frames or disabled.
Colour Depth
This parameter determines the number of bits required to define the color of every pixel. The maximum (and
default) value is ‘24 bit’. By reducing the value you can significantly reduce bandwidth consumption, at the cost
of video color reproduction. Options: 24 bit, 16 bit or 8 bit.
Use Default DDC and Choose Default DDC
When the
Use Default DDC
option is unticked, AdderLink Infinity will use the EDID that is reported by the
monitor connected to the receiver unit. However, if you tick the
Use Default DDC
option, you can then select
from a range of preset video resolutions from the
Choose Default DDC
drop down box. Once selected, the TX
will report itself capable of only supporting this one video resolution. Please note that all of the listed video
resolutions are single link DVI with a maximum pixel clock of 165MHz and a 60Hz refresh rate.
Enable Hot Plug Detect...
When this option is ticked, every time the monitor is changed at the receiver unit, a hot plug detect message
will be sent to the graphics card of the PC attached to the TX unit.
Period of Hot Plug Detect signal
This is the length of time that a hot-plug detect signal is applied. The default of 25mS is sufficient for the
majority of graphics cards, however, a small minority may need to be given a longer a period.
Frame skipping percentage
Frame Skipping involves ‘missing out’ video frames between those captured by the TX unit. For video sources
that update only infrequently or for those that update very frequently but where high fidelity is not required,
frame skipping is a good strategy for reducing the overall bandwidth consumed by the system. Range: 0 to
100%.
To get here
1 If not already connected, temporarily
connect the AdderLink Infinity unit and a PC via a network
.
2 Run a web browser and enter the IP address of the TX unit. Default:
http://169.254.1.33
If the address is unknown, perform a
manual factory reset
.
