System introduction
Thank you for choosing the Rose Electronics CAT5e / CAT6
Compensator. The CAT5e / CAT6 Compensator is the result of
Rose Electronics commitment to providing state-of-the-art solutions
for today’s demanding workplace.
The CAT5e / CAT6 Compensator is designed to work in conjunction
with Rose Electronics’ CrystalView KVM extender product line. It
corrects the majority of skew issues caused by differences in cable
types, and electrical lengths of the CAT5x/CAT6 wire pairs. This
differing length of the RGB components can cause smearing and
color fringing. The red, green, and blue color channels can be
delayed from 0 to 36ns in increments of 3ns using the CAT5e /
CAT6 Compensator. Each color channel can be independently
adjusted so the three RGB components arrive at the monitor at the
same time to produce a clear image.

CAT5e / CAT6 COMPENSATOR MANUAL
INSTALLATION
Installation
Please refer to the safety section first before proceeding with any
installation or configuration of the CAT5e / CAT6 Compensator
product.
The CAT5e / CAT6 Compensator module can add a delay on the
red, blue, and green RGB color line pairs (pins 1&2, 3&6, and 4&5).
The fourth line pair (Pins 7 & 8) is routed straight through the
module with no delay (data lines). This configuration is compatible
with all models of Rose Electronics CrystalView CAT5 KVM
extenders. If your KVM extender is a different model, verify that the
pin-out or your extender is compatible. As long as the RGB colors
are routed on pins 1&2, 3&6, and 4&5 and the data is routed on pins
7 & 8, the module should function properly (See Table 1). The
actual RGB colors labeled on the module may differ with different
extenders (Blue may actually adjust the Red delay).
Connecting the CAT5e / CAT6 Compensator
The CAT5e / CAT6 Compensator should be placed in series with
the main CAT5x/CAT6 cable. It is normally placed next to the
Remote unit to allow for easy adjustments on both the Compensator
and the KVM extender. See Figure 2. When the Compensator
module has been installed, adjust the Remote unit for the best
image with no video delay set on the CAT5e / CAT6 Compensator,
then adjust the delay.

Switch settings
Before setting the delay switches, determine which colors need to
be delayed. Using the Remote KVM station, open a text editor and
enter some text using a large font (36 or greater). Use black text
with a white background. If color fringing appears on the right
edges of each character, that color is arriving at the monitor before
the other colors. Note the fringe color and adjust the appropriate
color delay switch using Table 2 as a guide. Adjust the switches
while viewing the image on the Remote KVM station’s monitor.
Note: When switching in/out the delay switches, the sync pulse are
interrupted and you may temporarily lose the picture. Each
delay setting (3, 6, 9, and 18ns) uses two switches, eight
total. Make sure both switches for each delay setting is set to
the same position. For example, to set the Blue channel to a
12nS delay, switches 1, 2, 5, and 6 would be set to the delay
position.
Figure 3 shows an example of setting a delay of 3ns for the Blue
channel, 15ns for the Green channel, and 24ns for the Red channel.
The shaded areas represent the position of both switches. The
delay added to any given color is the sum of the set switches for
that color. If you needed a delay of 30nS, you would set both
switches for the 3nS, 9nS, and the 18nS switches (3+9+18=30).
Alternative Skew correction method
Presently on the market, there are two main types of CAT5x/CAT6
cables. One is referred to as a 2+2, where two of the four pairs are
similar in electrical length and the other two pairs are a different
electrical length. The other type is referred to as a 3+1, where three
pairs are similar in length. If you encounter skew using the 2+2 type
cable, a Compensator module needs to be used because, to obtain
the clearest possible image, there must be three pairs of similar
electrical length wires, one for the red, green, and blue channels.
If a skew is present using a 3+1 type CAT5x/CAT6 cable, the three
similar twisted pairs for the color channels could be pair swapped on
the RJ45 pins to switch the RGB signals.
TIP: If a color needs compensating, start with a delay setting of
18nS and increase or reduce the delay as needed.
