Description:
The CXM and CHM series crossover insertion
cards are designed for use with the CX452 modular
card cage (sold separately). These units are
components of the Nitek UTPLinks video, data &
power twisted pair system.
The CXM and CHM crossover cards are unique
unshielded twisted pair (UTP) transmission products
designed to operate with TIA/EIA standards-based network
cabling. The cards plug into and are powered
through the CX452 modular card cage. The CX452 is a
1 RU card cage that holds up to 5 of the crossover insertion
cards. Power is supplied from a separate PS105
or PS110 Power Supply (sold separately). The
crossover system and power supply are typically located
in an IDF (telecom) closet. There are four card models available and any of the four can be plugged into the card cage in any combination. Each card is designed to accommodate 4 cameras.
The primary function of each of the cards is to provide a means of interfacing copper backbone cables to horizontal cable runs and inserting voltage to the individual camera and/or P/T/Z over the horizontal run. In addition, models of the cards are available that provide RS422 distribution and/or video transceivers (see available cards - under Ordering Information). Using a single standards-compliant 4-pair UTP category 5 or better cable, video, data and power can be sent up to 100 meters to a fixed or P/T/Z camera.

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 Cat 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.

and proper installation techniques, please call 800-528-4343
