NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2”
(0.84-1.27 cm) when making a connection. The twists are critical to canceling out
interference between the wires.
The maximum transmission distances between repeaters are determined by the video
resolution sent over the wires. The total distance that video can be sent using
repeaters is shown in the following table for CAT5e/Shielded Twisted Pair (STP)
cable and DigitalMedia cable. While up to three repeaters may be used to extend the
transmission distance, the aggregate cable length of a signal path originating at a
DM-MD8X8 and terminating at a DM-RMC-100 DigitalMedia Room Controller
must not exceed 450 feet (137.1 meters) when using DigitalMedia cable (400 feet
(121.9 meters) when using CAT5E/STP cable). The following table shows the
maximum cable lengths allowed between repeaters when using DigitalMedia cable
or CAT5E/STP cable.
