Chapter 4: Configuration

4.7.3 Transmitters > Configure Transmitter Page

When you click for a particular transmitter, this page lists information about the unit and allows numerous settings to be configured.

4.7.3.1 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.

4.7.3.2 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.

4.7.3.3 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.

4.7.3.4 DDC

Allows you to use a global DDC setting, the monitor’s DDC or a particular DDC chosen from the list.

4.7.3.4.1 Background Refresh

The transmitter sends portions of the video image only when they change. 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’, 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 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.

4.7.3.4.2 Color 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.

4.7.3.4.3 Peak Bandwidth Limiter

The transmitter 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 transmitter will use considerably less than the maximum available. 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 100%.

4.7.3.4.4 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 100%.

4.7.3.5 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.
