Hardware Installation and Master Unit Set-Up:
Coax Backbone
It is highly recommended that quality cables and connectors be used for all video and audio
source connections, that the rack be grounded and that the Hubs be powered through a UPS
system.
1. The Hub
is designed to be rack mounted in a standard EIA 19” rack. Rack all units in the
install but DO NOT POWER units up at this time.
Use a quality 75Ω RG6 or RG11 coaxial
cable with “F” connectors to cable the coax cascade backbone to all units (Reference
Following
Cascade
section). Recommended that you use Z-Band design drawing.
2.
Connect the CAT patch cords from the front panel RJ45’s to the proper port in the Patch
Panel.
(Always use matched patch cords to the infrastructure cable, i.e. if CAT 6
infrastructure, use CAT 6 patch cord, if CAT 5e infrastructure, use CAT 5e patch cords,
etc.)
3. Attach ZHC Baluns (ZBT0010085 or ZBT0010021) with patch cords at each video drop, using
the TO WALL RJ on the balun. Using good quality RG6 Cable with F connectors, attach to
Balun and to TV Tuner.
4. At RF headend adjust signal so that the input to the MASTER ZHC is 20+/-2 dBmV for all
channels across the spectrum for digital or is 23 dBmV+/-2 for analog. It is extremely
important that the whole spectrum is FLAT (0 slope) for the system to preform properly. Also
ensure that the signal quality is good. That means for all digital signals a MER of >36dB and
for analog signals a CN of >46 dB. If your quality is below that going into the system, the
resulting feed may encounter problems. If your feed is bad, please contact your Cable
Service Provider to correct.
NOTE: These measurements should be taken at the end of the cable that is to attach to the
Master ZHC
