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.
