Description:
The CHM12A and CXM12A Crossover Insertion Cards
designed for use with the CX452 Modular Card Cage
(purchase separately). These are components of the
NITEK UTPLinks Video, Data & Power Twisted Pair
System.
The CHM12A and CXM12A Crossover cards are unique
unshielded twisted pair (UTP) transmission products designed
to operate with TIA/EIA standards-based network
cabling. The CHM12A and CXM12A provide 12VDC for
DC powered cameras. When used with other UTPLinks
cards 12VDC cameras can be mixed with 24VAC cameras
in a system. The CHM12A has built in receiver units.
The CXM12A is designed for midspan power applications.
The cards plugs 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
(purchase separately). The Crossover system and Power
Supply are typically located in an IDF (telecom) closet.
Each card is designed to accommodate 4 cameras. The
primary function of the cards is to provide a means of
interfacing copper backbone cables to horizontal cable
runs and inserting voltage to the individual camera over the horizontal run. Using a single standards compliant
4-pair UTP Cat 5 or better cable, video, and power can be sent up to 100 meters to a fixed camera.
