Keyboard Control

This option displays a keyboard control dialog and is useful for sending keyboard 
combinations (to the host) that are needed regularly or that are trapped by the 
AdderLink IP Gold.

When entering codes: 

+   means press down the key that follows
–   means release the key that follows
+–  means press down and release the key that follows

*   means wait 250ms (note: if a number immediately follows the asterisk, then   

the delay will equal the number, in milliseconds)
It is automatically assumed that all keys specified will be released at the end, so 
there is need to specify -Ctrl or -Alt if these keys are to be released together.
See 

Appendix 8

 for a list of key sequence codes that can be used.

Examples:
‘Ctrl + Alt 12’ would be expressed as: +Ctrl+ Alt+1–1+2
+N means press the ‘N’ key
+Scroll means press the Scroll lock key
+Space means press the space key

Sound control

This option provides a range of options related to the audio capabilities of the 
AdderLink IP Gold.

Format

uLaw

 - Use when 

transmitted data needs 
to be minimised - 8-bit 
compressed data.

Linear

 - Use when 

high quality audio 
performance is required 

- 16-bit uncompressed 

(raw) data is 
transmitted.  

Sample rate

The number of 
audio samples per 
second (in Hz). 
8000 produces less 
samples and hence 
minimised data. 
48000 (48KHz) 
produces the best 
sound reproduction. 

Channels

Allows you to 
choose between 
Mono and Stereo. 

Window size (ms)

The time frame in 
which the unit requires 
an acknowledgement 
from the remote viewer 
when data is sent. If 
acknowledgements are 
not received, the unit 
will stop sending audio 
data - Click the Restart 
Sound button.

Threshold

The level above which 
the audio level should be 
before it is considered to 
be not background noise 
and hence should be 

transmitted. A level of 25 

means the audio input 

needs to be above 25% 

of the maximum before it 
is transmitted.

Min burst (ms)

The time period for 
which the audio input 
must fall below the 
threshold level before 
audio transmission 
ceases. Transmission 
will begin again as 
soon as the threshold 
level is once again 
exceeded.  

Settings can be adjusted to suit transmission characteristics and audio quality 
requirements (unsuitable audio settings can affect video quality):

For maximum audio quality:

Format:  

Linear 

Sample rate:  

48000 

Channels:  

Stereo

For use on slow links:

Format:  

uLaw 

Sample rate:  

8000 

Channels:  

Mono

Where necessary, adjust the Window size, Threshold and Min burst settings until 
optimum audio output is obtained.

Restart Sound

Click to re-
enable audio 
transmission 
following an 
automatic 
cutout. If cutouts 
occur regularly, 
try increasing 
the Window size 
setting.
