MRC44 Keypad Cable Connections at the MRC44 Controller/Amplifier
(BASIC/ADVANCED/EXPANDED)
1. See Figure 10 for termination of the CAT5 cables to the RJ45 connectors.
2. Connect the zone keypad to the appropriate zone Keypad connector on the rear of the MRC44
Controller/Amplifier.
Video Connections
(BASIC/ADVANCED/EXPANDED)
Composite Video
1. When running composite video to a TV or monitor, use RG-6 coaxial or RG-59 quadshield cable with RCA
type phono plugs on each end. This connection can be run for 150 feet, as this is a buffered video output
from the MRC44 Controller/Amplifier.
2. Connect the zone video cable to the appropriate zone video jack on the rear of the MRC44 Controller/
Amplifier.
Modulated Video
3. When modulating the zone video output and using the RF/ANT input to a television, connect the VIDEO
OUTPUT from the MRC44 Controller to the VIDEO INPUT of a Modulator, using high quality RCA type
video patch cords. Use RG-6 coaxial cable with "F" connectors on each end to connect the Modulator, to
the RF/ANT IN on the room TV.
Control Out and Status Connections
Status
(BASIC/ADVANCED/EXPANDED)
Each zone has a Status Output that provides a control output of +12 VDC, 50mA that turns on and off with
the zone ON/OFF condition. ON = +12VDC, OFF = 0VDC. Using a 3.5mm mono mini phone connector, this
control can be used to close a relay, such as a Xantech CC12, to raise a TV lift or drop a projection screen
automatically when a zone is turned ON.
Control Out
(BASIC/ADVANCED)
A single Common Control Output is provided. When the Common Control Output is High (+12 volts, 50
mA), this indicates that at least one zone is ON. When the Common Control Output is Low (0 volts), this
indicates that all zones are OFF. Using a 3.5mm mono mini phone connector, this control can be used to
close relays (Xantech CC12) or turn on an AC outlet (Xantech AC1, AC2) for activity common to the
system.
