MULTI-ROOM SYSTEM CONTROLLER RMZ-955

Data cable connections

Data communication to and from the RMZ-955 controller and the remote zones’ RSM-901 sensor/displays and RKP-901 keypads is by 6 conductor shielded cable.

Note: One, and only one, data cable runs from the RMZ-955 to each zone. Multiple sensor/display and keypad combinations in one zone should be wired via series connections detailed in the section on Zone Connection Strategies (page 15).

We recommend the use of Belden 9536 cable or the equivalent. The Methode data connectors supplied with the RMZ-955 only accept cable with 24 gauge conductors.

Using cable with a foil and/or braided shield is absolutely essen- tial in maintaining data integrity over the long runs between the controller/amplifier and a zone’s control code generating de- vices. Make sure that the shield is firmly connected at both the RMZ-955 and at any command device terminal.

We recommend that you run each zone’s data cable and speaker cables together to save time. There is absolutely no performance penalty for doing so.

PROPER DATA CABLE TERMINATION IS CRITICAL. All connec- tions for RMZ-955 and the remote zone’s RSM-901 sensor/dis- plays and RKP-901 keypads use the color code shown in the following illustration:

DATA CONNECTOR

WIRING CODE

1 2 3 4 5 6

Pin 1• black & shield

Pin 2• white

Pin 3• red

Pin 4• brown

Pin 5• blue

Pin 6• green

Connections are made in the same order at both ends of the cables.

The supplied Methode connectors need to be crimped to lock to the data cable’s 24 gauge conductors.

Note: Do not use a screwdriver, metal ruler or knife blade to “crimp” these connections. You may think these tools will work but you will be mistaken. USE THE DEDICATED CRIMPING TOOL SPECIFICALLY DESIGNED FOR THESE CONNECTORS. This tool is available from Rotel.

•Strip about 1.5" of the outer cable insulation using a sharp knife. Separate the outer shield from the conductors and trim it off flush with the outer insulation, being careful not to trim off the shield or “drain” wire.

•DO NOT strip insulation off the six individual conductors as the connector automatically makes contact with the conductor core when crimped.

•Place the shield or “drain” wire into slot 1 of the connector. Then, place the BLACK conductor immediately on top of the drain wire in slot 1, hold them both in place and push the crimp- ing tool handle until you hear a slight “click.” Both conductors should now be locked into slot 1. The rachet action of the crimp- ing tool ensures proper connection. The clicking sound tells you that the connector slot contacts have pierced the conductor’s insulation.

•Continue the process following the color code guide above until all other conductors are locked in the appropriate connector slots. Remember that slot 1 is the ONLY ONE to get the drain wire and a conductor. All other slots receive only a conductor.

After attaching the cable conductors to the connector, insert it into the appropriate zone’s 6 pin data terminal on the RMZ-955’s rear panel. Be careful to center the connector over the terminal pins before inserting.

The maximum cable length for guaranteed operation is 300'. Longer lengths may be practical in some installations with low RF (radio frequency) and EMI (Electro-Magnetic Interference).
