To apply remote user video compensation
1On 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.

3When 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.
Remote user skew adjustment
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 |
| 1 2 3 4 5 6 7 8 |
| |
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. | 8 | 8 | Data signal | |
To alleviate this situation, the Adder | ||||
7 | 7 |
| ||
X100AS/R and X200AS/R modules provide | 6 | 6 | Red | |
internal skew adjustment that can help to | 3 | 3 | video signal | |
|
|
| ||
rectify the situation. The skew adjustment | 5 | 5 | Green | |
works by delaying or advancing the timing | 4 | 4 | video signal | |
2 | 2 | Blue | ||
of any of the red, green or blue colour | 1 | 1 | video signal | |
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 www.adder.com or www.adder. info 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.
