Transmitters > Configure Transmitter
When you click
for a particular transmitter, this page lists information about the unit
and allows numerous settings to be configured.
IP Address
Allows you to alter the IP address of the transmitter unit. Any change in address will be
enacted when you click the "Save" button at the foot of the page. Any IP connections
currently made to the transmitter will be ended.
Device Name, Description and Location
These are useful identifiers for the transmitter unit and its exact location. These become
even more valuable as the number of transmitters within the system increases.
Enable Dummy Boot Keyboard
It is often necessary to have a keyboard reported at start up. This setting means that a
"Virtual Keyboard" is always reported to the USB host. It may be necessary to disable
this for use with some KVM switches.
Usb speed
Select Low/full speed or High speed USB operation.
USB Hub Size
Select either a 13 or 7 port USB hub. This determines the number of USB devices that
can be connected to a single Transmitter.
Peak bandwidth limiter
The transmitter will use as much of the available network bandwidth as necessary to
achieve optimal data quality, although typically the transmitter will use considerably less
than the maximum available. In order to prevent the transmitter 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 transmitter. Range: 1 to 95%.
Video settings
This section allows you to directly adjust various key video controls within the
transmitter in order to obtain the most efficient operation taking into account
connection speeds and the nature of the video images sent by that transmitter.
DDC
Determines whether video configuration details should be harvested from connected
display screens or a static fixed EDID report should be used. Care must be taken when
selecting a Dual Link Video resolution as only ALIF dual units support a Dual Link Video
resolutions. In the case of a Dual Link EDID being set in the Global settings, no EDID will
be set on Video port 2 of the ALIF dual transmitters.
Hot Plug Detect Control
Determines whether to enable hot plug detection for video displays. By default this is
enabled.
Hot Plug Detect Signal Period
By default this is set at 25ms, which is sufficient for most graphics cards. Occasionally it
may be necessary to adjust this. An Adder engineer will advise if necessary.
Background Refresh
The transmitter sends portions of the video image only when they change. In order to
give the best user experience, the transmitter 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', mean-
ing 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 transmitter 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.
Frame Skipping
Frame Skipping involves 'missing out' video frames between those captured by the
transmitter. 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 99%.
serial settings
Serial Parity, Serial Data Bits, Serial Stop Bits, Serial Speed
This group of settings allows you to define the key parameters for the AUX port of the
transmitter so that it matches the operation of the device attached to it.
