MZC-88 Installation Instructions Page 25
VIDEO
Requirement - Pull home runs of RG6 quad-shield coaxial cable from every TV/Video Display location to the System
Head-End.
MAXIMUM LENGTH: 500’.
Installation - Terminate the head-end side with a male F-type connector to connect to the appropriate ZONE VIDEO
OUT on the MZC-88.
NOTE: The ZONE VIDEO OUT terminals on the MZC-88 are F-type connectors that output COMPOSITE VIDEO. These
should not be confused with F terminals that output RF signals. The zone end of the RG6 can be terminated with an RCA
connector and connected directly to the TV/video display composite video IN or terminated with a male F-type connec-
tor and adapted to the RCA jack on the TV/video display.
SPEAKERS
Requirement - Pull home runs of 18-14AWG two-conductor quality stranded speaker wire from all speaker locations to
the System Head-End.
MAXIMUM LENGTH: 18AWG up to 50’; 16AWG up to 200’; 14AWG up to 1000’.
Installation - Strip approximately
1
⁄4” off each end of each conductor and twist the stripped ends so there are no loose
strands that can cause shorts. On the Head-End side, carefully slide the individual conductors into the appropriate L+,L-/
R-,R+ speaker terminals on the removable screw down connectors that plug into the MZC-88 Zone Speaker OUT Termi-
nals. Terminate the speaker ends as appropriate for the given speakers. Maintain proper polarity.
WARNING: The power amplifiers in the MZC-88 use Bridged (BTL) outputs. Speaker connections must be completely
separate for each channel and have NO common ground connections through any connected Speaker Selectors, VCs,
Test Equipment, etc. Failure to observe this may cause damage and void the warranty.
CONTACT CLOSURES
Requirement - Pull 28-14AWG two-conductor stranded wire from any location utilizing a contact closure from the MZC-
88 to the System Head -End.
MAXIMUM LENGTH: Will vary with application.
Installation - On the Head-End side, strip approximately
1
⁄4” off each end of each conductor and twist the stripped ends
so there are no loose strands that can cause shorts. Carefully slide the individual conductors into the appropriate Contact
Closure Terminal pair on the MZC-88 Rear Panel. Terminate the device end as appropriate. POLARITY: Head-End not
critical.
EXPANSION PORT/LOOP
Requirement - CAT-5 cable terminated with RJ45 connectors, pass-through configuration (pin to pin).
MAXIMUM LENGTH: 4000’
Installation - Connect CAT-5 cables terminated with RJ45 connectors to MZC-88 Port/Loop terminals in expanded sys-
tems. See section: Expanded Systems for additional information.
RS232
Requirement - Use a quality, pre-made Serial Cable terminated with DB9 connectors, pass-through configuration.
MAXIMUM LENGTH: 50’
Installation - Connect one end of the Serial cable to the RS232 DATA I/O Port on the MZC-88 Rear panel and the other
end to the device being controlled via RS232. NOTE: This connection requires configuration in EZ-Tools.
CONTROL PORT
Used for system programming and firmware updates. See section: Programming for additional information.
