CHAPTER 3: OPERATION – USER FUNCTIONS 39
Video Gain and Skew Compensation
When traveling the distance from the target server to the monitor connected to a user station over
different cables, Red, Green, and Blue (RGB) color signals may arrive at different times, causing
color separation on your monitor; what should appear as a solid white line may instead be
separated into three different colored lines: a Red, a Green, and a Blue.
Video Gain and Skew Compensation allow you to resynchronize the arrival of RGB signals by
adding a time delay on any color signal (R, G, or B) that arrives at your user station sooner. After
successful skew compensation, the RGB signals are resynchronized and form a solid white line
once more. Note that Skew Compensation is only available in P2-EUST and P2-EUST/C
while Video Gain is available in P2-EUST, P2-EUST/C and P2-UST.
Video Gain Adjustment and Skew Compensation in P2-EUST
Note that “Automatic” skew compensation is only available when you use P2-EUST (or
P2-EUST/C) and one of these CIMs: P2CIM-APS2, P2CIM-AUSB, P2CIM-ASUN,
P2CIM-APS2DUAL, P2CIM-APS2-B, P2CIM-AUSB-B or P2CIM-AUSB-C. However,
“Manual” skew compensation is always available with a P2-EUST (or P2-EUST/C)
regardless of the CIM type.
Automatic skew compensation adjusts the video quality automatically based on varying cable
distances and cable types. If this video quality adjustment on an active CIM using the P2-EUST
(or P2-EUST/C) is unsatisfactory, you can manually adjust the video gain setting and skew delay
of each color via the OSUI. Once adjusted, the gain setting and skew delay values are stored in
the database of the Paragon switch that the P2-EUST (or P2-EUST/C) connects to.
To adjust video quality on any channel, connect to the channel you wish to adjust. Press the Hot
Key (default: Scroll Lock) twice QUICKLY to activate the Selection Menu and press the * or /
keys on your numeric keypad to select one of four options: AGC, skew delay of Red, skew delay
of Green, and skew delay of Blue. Press the + or - keys on your numeric keypad to increase or
decrease the skew delay.
Skew compensation range is 0 to 31. The video gain changed adjustment value appears in the
Message Bar; press the + and/or - keys to adjust video gain from -15 to +15 (for P2-UST) or from
0 to +6 (for P2-EUST and P2-EUST/C) until you are satisfied with the video quality.
Please note that you must connect to each channel individually to adjust that channel’s video gain
and skew delay.
Please see Video Display Adjustment for P2-EUST under Channel Configuration in Chapter
4 for additional inform
ation.
