ACM9454 Communications Management Unit


ACM9454 Communications Management Unit

Communications Management model ACM9454 controls radio, transponders, TACANs, moving maps, and more. The ACM9454 series offers a sunlight-readable, NVIS-compatible, high-resolution, 5″ LCD display. Modular Communications Management Unit (CMU) software allows for rapid insertion of new technology and mission capabilities, and currently supported apps include moving map data entry, text messaging, DAFIF, search and rescue beacon navigation with additional capabilities developed on a regular basis. The ACM9454 is fully capable for communications with law enforcement and civil frequencies, such as VHF and maritime. For military aircraft, the ACM9454 is compatible with SATCOM, DAMA, UHF and more, and is capable of supporting numerous radios, transponders and other systems through a software control licensing fee, simplifying logistics and integration efforts. Multiple variations of connectors and data ports are available, including a drop-in replacement for ARC-210 C-12561A remote control units.

See the ACM9433 and ACM9443 for smaller, more space-saving models.

View up to four radio devices at once. The active radio tuning details are shown on the left with information such as radio frequencies, waveform, and preset description. The standby radio tuning appears on the right, showing similar information plus crypto key selection when applicable. The middle of the display shows instantaneous transmit and receive status of the radio.




Interface with a full range of avionics equipment, including TACANs, transponders, ADS-B receivers, navigation, and mission systems. Up to four CMUs may be interconnected in an aircraft installation to provide any-to-any control in multi-crew platforms.



Active and standby radio tuning information appears on the left while a scrollable preset list, TACAN navigation widgets, search and rescue direction finder indications or other CMU app features are shown on the right.




The onboard internal highspeed SBAS GPS allows the unit to integrate with the DAFIF worldwide database. Display bearing and distance information to any waypoint, navaid, or airport anywhere in the world.
