CX452 Modular Crossover Card Cage for 19" Rack Cabinet
   
  Component of the UTPLinks™ System
Revision Number:
100404

Description:
Modular crossover interface card cage for the UTPLinks™ video, data & power over twisted pair transmission system.

The CX452 is a 1 RU card cage designed to hold up to five modular crossover cards for the UTPLinks system, mounted horizontally. The card cage combined with plug-in crossover cards comprises a video crossover and power insertion unit for the UTPLinks system and depending upon the type of cards used, can also include RS422 distribution and/or video transceiver capability. Four models of four-channel crossover cards are available. The cards can be used in any combination, allowing the rack system to be customized to the specific application. (Modular cards are sold separately).

The CX452, configured with plug-in cards, is designed to work with TIA/EIA standards-based structured cabling networks. The crossover card cage provides a 50 pin Telco at the rear of the unit for easy interfacing with either a copper backbone cable or Nitek video receiver equipment. Separate 24 VAC power inputs are provided for each card at the rear of the unit. The CX452 requires the use of a Nitek PS105 or PS110 power supply.

Wire and Cable Recommendations

On horizontal runs with fixed cameras (applications up to 8 watts/ port) category 5 or better; 22 AWG or 24 AWG. For P/T/Z camera (applications >8 watts/port) category 5 or better; 22 AWG is recommended. In the case of backbone cable 24 AWG category 3 or better is recommended. Multi-pair cable with an overall shield is acceptable. While signals may be routed through 66 blocks or 110 blocks, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
