DCS-LAN Chain  

The DCS 6000 system uses Cat5e, Cat6 or Cat7 F/UTP 

or U/FTP cables with screened RJ45 connectors.  
EIA 568-B wiring shall be used. 

Important: 

The names of Cat5/6/7 cable type have 

changed.

Important: 

Use only F/UTP or U/FTP (screened) cables 

and screened RJ45 connectors and not U/UTP cable, which 

are unscreened.

The phase of the pairs must be correct and the wiring 

spec. as stated in Cat5e (EIA 568-B) have to be 

followed. 

Note:

 Cat6 and Cat7 cables can normally only be terminated 

in sockets (female) and not in cable plugs.  
Cat6 and Cat7 can thus only be used for feeding cables 

terminating in wall outlets or patch panels.
