shown in figure 11. You will need a short patch lead to do this.
The settings that are reported represent the compensation required to remove the
skew that is introduced by the twisted pair cable. There is sometimes some colour
skew present on video signals being generated by the computer. Consequently the
video picture can sometimes be slightly improved by using skew compensator
settings that are slightly different to those reported (see section 6.5).

For the technically minded . . .
When the skew compensator is used with AdderLink KVM extenders, switch bank A
(i.e. switches A1 to A4) adds delay to the twisted pairs that carry the BLUE colour. In
the same way, switch banks B and C add delay to the twisted pairs that carry the
RED and GREEN colours respectively. Other KVM extenders may carry colour
signals on different twisted pairs.
The delays added by the various switches are as shown below. Switch 1 adds the
most delay and switch 4 adds the least delay. Any combination of switches may be
selected to make up the required delay (e.g. switches 1,3 and 4 together will add a
total delay of approximately 17.5 nanoseconds).
Switch 1
10 nanoseconds
(equivalent to 2 metres of cable)
Switch 2
10 nanoseconds
(equivalent to 2 metres of cable)
Switch 3
5 nanoseconds
(equivalent to 1 metre of cable)
Switch 4
2.5 nanoseconds
(equivalent to 0.5 metres of cable)

Setting up the skew compensator manually
If the skew compensator is to be used with a KVM extender that does not have a
skew setting reporting feature then you will need to setup the skew compensator
manually. To do this you will first need to determine which of the switch banks
