Adder Technology 1000 User Manual

1  On the remote user keyboard (connected to an Adder X100/X200 extender), 

simultaneously, press the hotkeys (by default, 

 and 

) along with 

 to 

enter configuration mode.
The three keyboard indicators (‘Num Lock’, ‘Caps Lock’ and ‘Scroll Lock’) 
will now begin to flash in sequence. The speed of the sequence indicates 
the level of the sharpness adjustment currently 
applied: the slower the rate, the lower the level of 
sharpness being applied.

2  While viewing the displayed screen image, use the 

following keys to adjust the controls:
Sharpness:     for fine adjustment,     for 

coarse adjustment.

There are 255 sharpness levels (one coarse step jumps 10 levels).
To autoset sharpness (X100 modules only): Press       

to make the module calculate and apply an automatic 
compensation level - you can use this as a starting point for your 
fine tuning.
Note: If the monitor goes blank and switches off (due to oversetting 
the sharpness adjustment) press the Home key to restore.

Brightness:     for adjustment. There are 255 brightness levels.   

3  When no shadows are visible and the displayed images have crisp edges, 

press 

 to exit configuration mode and permanently save all settings.

  The new compensation settings will be stored, even when power is removed 

or if a complete reset is initiated. These settings should not require further 
changes unless the cabling arrangements are altered. 

The category 5, 5e and 6 cabling supported by the AdderView CATx 1000 consists 
of four pairs of wires per cable. Three of these pairs are used to convey red, green 
and blue video signals to the remote video monitor. Due to the slight difference 
in twist rate between these three pairs, the 
red, green and blue video signals may not 
arrive at precisely the same time. This is 
visible as separate colour shadows on high 
contrast screen images and is particularly 
apparent when using higher screen 
resolutions and some types of category 5e 
cables.
To alleviate this situation, the Adder 
X100AS/R and X200AS/R modules provide 
internal skew adjustment that can help to 
rectify the situation. The skew adjustment 
works by delaying or advancing the timing 
of any of the red, green or blue colour 
signals so that they are all delivered to 
the monitor at precisely the same time. For best results, the “skew” program 
supplied on the disk or downloadable from 

 is the most accurate way of setting skew as the red, green and blue lines 

are rendered exactly on the screen as single pixel wide lines. The skew.bmp test 
pattern can also be used but it is less accurate. Alternatively, you can create your 
own skew pattern using a standard image creation package, as detailed on the 
next page.
