Introduction The CMX-144 is the industry’s most controllable 4x4 component video matrix, featuring multiple control interfaces, a wide variety of video and audio inputs, and a durable, attractive design sure to compliment any equipment rack or shelf. Capable of distributing four component, analog audio, and digital audio sources to four destinations, the CMX-144 is perfect for simple installations in mid-sized homes and small commercial applications.

Getting Started Model 1106 IR Remote Control • Read this entire instruction manual. • Confirm that nothing is missing from your shipping carton (see below). • Activate your warranty and receive future upgrade notifications by registering your purchase on our website: www.audioauthority.com/register. Each CMX-144 includes one 1106 remote; additional 1106 Remotes may be purchased separately, or you may download the IR codes from www.audioauthority.com. for use in programmable IR remotes.
Installation The CMX-144 is easy to setup for simple or advanced installations. Perform the following steps. 1. Rack Mount Adapters. If the CMX-144 is to be installed in a standard 19-inch equipment rack, remove the feet and the cover screws adjacent to the front panel of the unit and use them to mount Model 1192A rack adapters. Be sure to place a spacer under the adapters at every screw location – see illustration. ! CAUTION! This product will be damaged if spacers are not used on every adapter screw.
Advanced Setup and Remote Control Options Three different methods may be used for setup and matrix switching: infrared, serial (RS-232), or Ethernet. All switching commands are available using any of these methods, but advanced configuration such as IP address settings, status queries etc. must be performed via the serial port, or using serial commands via the Ethernet port. 1. Using a Comprehensive IR Control System. The CMX-144 can be used right out of the box; no setup is necessary.
Operation 1. Front Panel Keys. The front panel is operated by touching the sensitive “key” areas: POWER, SOURCE, and DIM. • Touch POWER to turn the unit on or off (low power mode). • Each time you touch a SOURCE key, the CMX-144 switches to the next available source. • Any restricted zones are skipped (if source 1 is restricted other zones select source 2, 3, 4, and then back to 2). • The power button puts the unit in “low power mode”.
Appendix A: Serial Commands Description Command Structure Commands can be used at any time via RS-232 or Ethernet to change the CMX-144 settings. Certain commands, such as [FLASH] to upgrade firmware, can be used only via RS-232. See page 4 for details. Channel switch – switches a source input to a zone output. There are many possible modifiers, such as V for video, A for a audio, X for all. .
Example Command(s) Example Output Result [C,Z1,I1] [C,Z1,A,I2] (Z1,I1) (Z1,A,I2) Zone 1 is connected to source audio and video 1 provided that no other zone has restricted this source. Zone 1 is connected to source 2 audio and the video is left as it was before, assuming that source 2 is not restricted by another zone. [P,F] [P,N] (P,F) (P,N) Switch into low power mode, switch back into normal operating mode. [I,2] (I,2,35) Front panel zone indicators dim to level 2. Values=1-3 and 0=off.
Query Commands The [?] serial command displays the table of zone/source mappings including restrictions. Specific query commands include the following characters: Z# represents ZONE # and S# represents input source #. X represents the currently selected input source V represents the currently selected video source (break-away) A represents the currently selected audio source (break-away) T represents a source that is unavailable to be selected due to a temporary restriction.
Appendix C: Troubleshooting Symptom Causes and Solutions No video • Check that the correct input is selected on the zone • Check that the video is connected to the correct Y Pb Pr inputs on the TV • Check cables for damage No analog audio • Connect analog audio to the inputs and from the outputs of the CMX-144 – digital audio does not produce sound on the analog audio outputs.
