KRAMER:  SIMPLE CREATIVE TECHNOLOGY

 

Overview 

 

3  Overview 

Our Kramer 

Cobra

 series products are compatible with Cat5/5e/6 data 

cabling as well as skew free CAT5/5e cabling manufactured for video 

applications. Note that some skew free Cat5 is specific to a particular vendor 

and is not compatible with our products. Ensure any skew free CAT5 cable is 

non-proprietary prior to purchase / installation. 
We recommend using our Kramer 

Cobra

 ultra low skew cable—

BC-HDTP

 

(solid bulk) or 

BCP-HDTP

 (solid plenum bulk)—available in lengths of 700' 

(210m) and 1300' (390m). 
CAT6 cable, due to the manufacture method, can exhibit much greater skew 

than standard CAT5/5e and may require skew compensation beyond what the 

standard product offers. Contact Kramer Electronics for assistance. 
CAT5/5e/6 cabling for this product must be pinned to the TIA-EIA T568B 

wiring specification (see appendix A). We also highly recommend that all 

CAT5 cables be pre-terminated and tested. Cables terminated on-site or in an 

existing infrastructure should be tested before use to ensure compliance with 

the TIA-EIA T568B specification. Using incorrectly terminated CAT5 cables 

can damage this product. 
Achieving the best performance means: 

 

Connecting only good quality connection cables, thus avoiding 

interference, deterioration in signal quality due to poor matching, and 

elevated noise levels (often associated with low quality cables) 

 

Avoiding interference from neighboring electrical appliances that may 

adversely influence signal quality and positioning your 

Cobra TS2 

in a 

location free from moisture and away from excessive sunlight and dust

wall adapter that is provided with this unit

Warning

 –This equipment is not intended for, nor does it 

support, distribution through an Ethernet network. Do not
