DTP T EU 332, DTP T EU 232, DTP T MK 332, and DTP T MK 232 • Installation and Operation 14
Cable recommendations
Extron recommends using the following practices to achieve full transmission distances
up to 330 feet (100 meters) (DTP T EU 332 and DTP T MK 332) or 230 feet (70 meters)
(DTP T EU 232 and DTP T MK 232) and reduce transmission errors.
• Use the following Extron XTP DTP 24 STP cables and DTP 24 connectors for the best
performance:
• XTP DTP 24/1000 Non-Plenum 1000’ (305 meters) spool 22-236-03
• XTP DTP 24P/1000 Plenum 1000’ (305 meters) 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 hook-and-loop fasteners.
• Separate twisted pair cables from AC power cables.

NOTES:
• The IR Tx and Rx line pair and the RS-232 Tx and Rx line pairs must each cross
once between their connectors and the source or destination.
• The length and preparation of exposed wires is important (see the second and third
power connector CAUTIONS on the next page for details).
