3.1 Introduction
Information in this section consists of the functional and operational procedures for the RM01-001 Remote
Memory (RM01).
3.2 General Information
The RM01 is a Remote memory unit for the Northern Airborne Technology Ltd. (NAT) Digital Audio
Communication System (DACS).
The DACS is a communications management system that distributes and controls all of the audio in an
aircraft. It manages the audio from all transceivers, receivers and audio warning sources. It enables the
transmission of microphone audio to a selected transmitter and distributes all Inter-Communication
System (ICS) audio.
The RM01 is a remote mounted device that connects to the DACS AMU50 Audio Management Unit. The
RM01 stores the system’s configuration and aural alert files. Storing the system configuration and alert
files in this unit enables the replacement of the AMU50 without the need of downloading a new
configuration file.
The RM01 communicates with the AMU50 over a Serial Peripheral Interface (SPI) port. The RM01 also
receives regulated power from the AMU50.
Optionally, more than one RM01 may be used in an aircraft to provide rapid re-configuration of an aircraft
audio when an aircraft is assigned to a different role. The connector on the harness from the AMU50 can
be moved to the RM01 which contains the configuration appropriate to the required role.
The RM01 Remote Memory has no operator accessible controls.
