Figure 3. Default Switch Positions
If you want to transmit video over 4,000 feet (1,219 meters) of UTP cable, set switch 1 to 4K. Set
switch 2 to 3K if you want a distance of 3,000 feet (914 meters), switch 3 to 2K if you want a distance
of 2,000 feet (610 meters), and switch 4 to 1K if you want a distance of 1,000 feet (305 meters).
You can set only one distance at a time.
With switch 5 you can select H (high) or L (low). High mode is the default position and is used when
video is 1Vp-p. Low mode is used when video is less than 1Vp-p.
