MRC88M KEYPAD CAT5 CABLE CONNECTIONS AT THE MRC88M CONTROLLER/AMPLIFIER

(BASIC/ADVANCED/EXPANDED)

The MRC88m ‘Pin-to-Pin’ CAT5 cabling that can be purchased pre-fabricated at fixed lengths or self-assembled to custom lengths. The color-coded wiring standard is EIA/TIA 568B as shown in Figure 10. The plastic connector on the end of the CAT5 wire is “registered jack” RJ45.

1.See Figure 10 for proper 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 MRC88m Controller/Amplifier – Figure 3-(16).

Caution: Power voltage for the keypad is transmitted along this cable! Incorrect wiring on this cable can destroy the MRC Keypad! Be sure to test cable for proper connections before making connections.

VIDEO CONNECTIONS (MRC88M ONLY)

(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 up to 150 feet, as this is a buffered video output from the MRC88m Controller/Amplifier.

2.Connect the zone video cable to the appropriate zone video jack on the rear of the MRC88m Controller/ Amplifier – Figure 3-(18).

Modulated Video

3.When modulating the zone video output and using the RF/ANT input to a television, connect the VIDEO OUTPUT from the MRC88m Controller – Figure 3-(18),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.

STATUS CONNECTIONS AND COMMON CONTROL OUT

Status

(BASIC/ADVANCED/EXPANDED)

Each zone has a Status Output –Figure3-(19),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. Connect one end of the 3.5mm Mono
