UTPLinks Crossover, RS422 Distribution & 24 VAC Power Insertion Module with 4 Video Transceivers - For Use with CX452

The CHM22 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 CHM22 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 PS115 power supply (sold separately). The crossover system and power supply are typically located in an IDF (telecom) closet. There are three card models available and any of the three 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.

Features:

  • Three available plug-in cards provide flexibility - any combination of four Crossover cards can be used in any of the CX452 card cage slots
  • Plug-in cards also provide future system expansion or features modification
  • Each of the cards cover 4 zones with separately fused outputs
  • One 4-pair category 5 cable can be used for video, RS422 and 24 VAC
  • Detection LEDs for power (all cards) and RS422 (CXM22 & CHM22)
  • TIA/EIA 568B compatible

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.

Super comfortable
Color: Green Bamboo(2300gsm), Size: Queen
this mattress topper completely saved my bed. It is super thick and soft, but still gives enough support so you don’t feel totally stuck. The cooling cover actually works pretty well and doesn't trap heat like other memory foam I’ve tried in the past. It was also really easy to put on and the deep pockets keep it from sliding around at night. Very happy with it!

Mattress Topper
Color: Green Bamboo(2300gsm), Size: Queen
So far I haven’t really got to get a feel of it. I will say it came smelling very strongly. I’ve had it now for 3 days & it still has a smell. I let it sit out for 24 hours, with the window opened but it still has an odd scent & once I put it on my bed it’s still smelling strong. It’s kind of hard to focus on my comfort when the smell is very odd & foul but aside from that. The reviews are on point in regards to its softness.
