ACM9443 Communications Management Unit


Control radios and data communication feeds with one device

Communications Management model ACM9443 functions as a single control head for the management of radios, transponders, TACAN, moving maps, and more. Designed with data ports prepared for technology expansion, supporting numerous connected devices and future growth; the ACM9443 is an ideal choice for enabling multi-role aircraft fleets and simplifying logistics. The ACM9443 is fully capable for communications with law enforcement and civil frequencies, such as VHF and maritime. For military aircraft, the ACM9443 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. The ACM9443 series products have multiple connector and I/O options, including a drop-in replacement for the ARC-231 C-12601 remote control indicator.

See the ACM9433 and ACM9454 for smaller and larger models, respectively.
