Twisted Pair Recommendations for DTP2, XTP, and HDBaseT Communication
Extron recommends using the following practices to achieve full transmission distances
and reduce transmission errors:
•
Use Extron XTP/DTP2 24 SF/UTP cables for the best performance. At a minimum,
Extron recommends 24 AWG, solid conductor, shielded twisted pair (STP) cables with
a minimum bandwidth of 400 MHz.
•
Terminate cables with shielded connectors to the TIA/EIA-T568B standard (shown at
right).
•
Limit the use of 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 shielded couplers and punch down connectors.
ATTENTION:
•
Do not connect these connectors to a telecommunications or computer data
network.
•
Ne connectez pas ces ports à des données informatiques ou à un réseau de
télécommunications ou de données informatiques.
•
DTP2 remote power is intended for indoor use only. No part of the network that
uses DTP2 remote power should be routed outdoors.
•
L’alimentation DTP2 à distance est destiné à une utilisation en intérieur
seulement. Aucune partie du réseau qui utilise l’alimentation DTP2 à distance
ne peut être routée en extérieur.
NOTE:
When using shielded twisted pair 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.
Audio Wiring
Wire the audio input and output connectors as shown at right. Use
the supplied tie wrap to strap the audio cable to the extended tail
of the connector. This does not apply to the amplified audio output
connector on the SA and MA models.
ATTENTION:
•
For unbalanced outputs, do not connect wires to the
“-” poles (see the illustration at right).
•
Pour les sorties asymétriques, ne connectez pas de
câbles aux pôles « - » (voir l’illustration
de droite).
NOTE:
The length of exposed wires is critical. The ideal length
is 3/16 inch (5 mm).
IR Over TP Wiring
To transmit and receive IR signals, connect a control device to the
three-pole Over TP IR connector (Tx, Rx, and G).
NOTE:
RS-232 data can be inserted via Ethernet only (see the
DTP2 CrossPoint 82 User Guide
for details).
