Figure 8. TP Cable Termination
NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201
cable to link the transmitter and receiver. The DTP T HWP 231 D and 331 D products
do not work properly with these cables.
Supported cables —
The DTP T HWP 231 D and 331 D transmitters are compatible with shielded twisted pair
(F/UTP, SF/UTP, and S/FTP) cable.
Cable recommendations —
Extron recommends using the following practices to reduce transmission errors and achieve
full transmission distances up to 230 feet (70 meters) for the 231 models and 330 feet
(100 meters) for the 331 models.
• Use the following Extron XTP DTP 24 SF/UTP cables and DTP 24 connectors for the
best performance:
• XTP DTP 24/1000 Non-Plenum 1000’ (305 m) spool 22-236-03
• XTP DTP 24P/1000 Plenum 1000’ (305 m) spool 22-235-03
• XTP DTP 24 Plug Package of 10 101-005-02
• If not using XTP DTP 24 cable, at a minimum, Extron recommends 24 AWG, solid
conductor, STP cable with a minimum bandwidth of 400 MHz.
• Terminate cables with shielded connectors to the TIA/EIA-T568B standard.
• Use no more than two pass-through points, which may include patch points, punch
down connectors, couplers, and power injectors. If these pass-through points are
required, use CAT 6 or 6a shielded couplers and punch down connectors.
NOTE: When using STP cable in bundles or conduits, consider the following:
• Do not exceed 40% fill capacity in conduits.
• Do not comb the cable for the first 20 meters, where cables are straightened,
aligned, and secured in tight bundles.
• Loosely place cables and limit the use of tie wraps or Velcro
®
.
• Separate twisted pair cables from AC power cables.
