Contact Closure Communication - Extron electronics XTP T USW 103 User Manual

Cable recommendations
Extron recommends using the following practices for XTP communication 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 connectors for the best
•
performance:
XTP DTP 24/1000
•
XTP DTP 24P/1000 Plenum 1000' (305 m) spool
•
XTP DTP 24 Plug
•
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 (see
on the previous page).
• 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.
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 m, 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.

Contact Closure Communication

Each port senses an external switch or contact closure. Use these ports to select an input
on the switcher from a contact closure device. Wire the connector as shown in figure 7.
