ATTENTION
:
• Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201
cable to link the XTP products or with DTP2 transmitters or receivers. The
DTP2 211 does not work properly with these cables.
• N’utilisez pas le câble audiovisuel Skew-Free UTP version améliorée UTP23SF-4
Extron ou le câble STP201 pour relier les produits XTP à des émetteurs ou
récepteurs DTP2. Le DTP2 211 ne fonctionne pas correctement avec ces câbles.
Supported cables —
The DTP2 211 transmitter and receiver are compatible with CAT 6a, and CAT 7 shielded
twisted pair (F/UTP, SF/UTP, and S/FTP) and unshielded twisted pair (U/UTP) cable.
Cable recommendations —
Extron recommends using the following practices to achieve full transmission distances up
to 330 feet (100 meters) and reduce transmission errors.
• 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 feet (305 meters) spool
•
XTP DTP 24P/1000
Plenum 1000 feet (305 meters) spool
• XTP DTP 24 Plug Package of 10
•
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 T 568 B 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.
NOTES:
When using CAT 6a and CAT 7 cable in bundles or conduits, consider the
following:
•
Do not exceed 40% fill capacity in conduits.
•
Do not comb the cable for the first 65 feet (20 meters), where cables are straightened,
aligned, and secured in tight bundles.
•
Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
• Separate twisted pair cables from AC power cables.
