Rotel RMZ-955 Infrared Control System, Front Panel IR Flood Emitter, Rear Panel IR Repeaters

Infrared Control System

The RMZ-955’s IR system provides extensive control flexibility accepting remote control codes generated by keypads and/or hand-held remotes, relaying them to the system controller, and passing them along to the source components via a front-panel flood emitter or individual remote IR emitters plugged into the rear panel. However, please note the following points:

The IR codes generated by the RR-952 hand held remote are RMZ-955 “system specific” codes and ARE NOT the same codes generated by a source component’s own controller, even for functions that appear identical such as “CD play,” for example. In other words, you can not use the RR-952 to directly control a Rotel CD player but must use it through an RSM-901 sensor/dis- play from a remote zone.

The RMZ-955 IR control system does the following:

•An RSM-901 sensor/display receives the remote’s code se- quence and translates it into proprietary 5 bit digital code.

•This digital code travels over the data cable to the RMZ-955 controller/amplifier.

•The RMZ-955’s translator card restores the code’s original con- figuration (when required) and sends it to both the IR flood emit- ter and the rear panel IR outputs for use by the appropriate source component.

In addition to passing RMZ-955 system codes, the IR system will pass ALMOST any IR code sequence from an RSM-901 to a source component. (These few exceptions use a non-standard IR transmission frequency.) This allows you to control transport functions of a VCR from a remote zone, for example, with the VCR’s dedicated hand held remote.

Front Panel IR Flood Emitter

The RMZ-955 features a front-panel flood emitter for sending IR codes to the source components own front-panel IR sensors.

Note: It is essential that the output of the front-panel flood emit- ter NOT be allowed to reach an RSM-901 sensor/display. This could result in an IR loop and unstable system operation includ- ing “lock-up”

RMZ-955s are shipped with the front panel IR flood emitter en- gaged. However, there may be applications (system installations on open shelves in very large, bright rooms, for example) where the IR flood emitter might interfere with proper source compo- nent operation or will not be particularly effective in communi- cating control pulses. Or, there may be systems where an RSM-901 display/sensor located in the same room as the RMZ-

955.In these cases, disable the front-panel flood emitter and use individual IR emitters connected the RMZ-955’s rear panel and placed over each source components IR sensor.

INSTALLATION: RMZ-955 CONTROLLER

To disable the IR flood emitter, remove the jumper wire between screws 2 and 3 of the TX FORMAT terminal block located on the lower right hand side of the RMZ-955’s rear panel.

Optional remote IR emitters for use in place of front panel IR flood emitter. One required for each source component.

Remove this jumper to disable front panel IR flood emitter.

NOTE: There is a very low intensity red LED mounted behind the emitter’s window which flashes whenever it is transmitting IR codes. Use this LED to verify the emitter’s operating status.

Rear Panel IR Repeaters

In many system configurations, the most reliable, trouble-free means of passing IR control codes to the source components is with individual IR emitters, one for each source. Use these op- tional repeaters in situations where the RMZ-955 will be located some distance away from the source components or where the IR flood emitter may have difficulty transmitting reliable source control data. Disable the flood emitter when using the optional IR remote emitters.

The RMZ-955 rear panel has four paralleled 3.5mm mini-plug sockets labeled “TX OUTPUTS.” They accept standard “stick on” IR emitter like Xantech’s Video Link 282-00. Plug a repeater into one of the sockets and place it over the source component’s IR sensor. Repeat for the other three sources.

Note: Some source components, such as some Rotel sources, al- low a direct connection from a 3.5 mm rear panel IR emitter con- nection to a matching 3.5 mm connection on the source component, eliminating the need for stick-on IR emitters.
