ADB-820H-MA-3000 Technical

The ADB-820H-MA-3000 digital encryption module for two-way radios provides a very high level of voice security (Class III plus), employing a proprietary AES encryption algorithm with the powerful combination of 72 quadrillion+ digital keys to prevent breeches of communication by the most determined adversaries. The ADB-820H-MA-3000 series utilizes a digital communication channel in a radio system that can consist of both portable and mobile radios to provide a cost-effective voice privacy solution for commercial entities, police departments, public safety, drug enforcement, governments and militaries to prevent eavesdropping on critical communications by unwanted listeners, drug smugglers, rogue terrorists, criminals or enemies.

When the radio user is operating in secure mode, the eavesdropper will not hear any vocalization; instead they will hear only “white noise” when speech is being transmitted. By using a digital communication channel in an analog radio communication system, voice quality is not compromised, providing for clear speech when the radio is used in secure mode. The module features background noise rejection which enhances the clarity and coherence of the message between the sender and the intended listener.

The ADB-820H-MA-3000 voice security module installs easily into the DP/DM3000 range (EMEA) of portable and mobile radios.

It provides a very high level of voice security in radio systems utilizing conventional analog repeaters in the 12.5/25 kHz radio spectrum. The ADB-820H-MA-3000 works in Simulcast, LTR, and voting systems as well as dispatch systems that feature Check, PTT-ID, OTAR, and GPS location information. The ADB-820H-MA-3000 digital encryption module is easily programmed via a personal computer (PC). It offers a programmable “autodetect” option, enabling automatic receive operation while the radio is in secure mode. Other options include compatibility with any frequency inverters using analog keys and compatibility with double-inversion voice band scramblers using analog keys. The ADB-820H-MA-3000 is available with powerful, advanced digital encryption up to AES256 for the utmost protection against adversaries who threaten the safety and security of life and property.

Additionally, these modules have a very unique feature that would allow with our technical guidance the end user to apply their own algorithm. Enabling this product to be customer specific.

Versions of the radios
For correct operation of APJ1 Media services modules in the Motorola MOTOTRBO the DP/DM3000 series radios is to have the corresponding version of the firmware and must have an activated Enhanced Audio/Data Routing Option (Part Number SW000449A01).

Note that the radio firmware version is not the CPS software version.

We strongly recommend using the latest firmware version for all radios to prevent compatibility issues.

The firmware version for DP/DM3000 series is to be R02.30.00 or higher.

Motorola Regional Compatibility
European Equipment: DP2400, DP2600, DP3400, DP3401, DP3600, DP3601.

Programming modules ADB-820H-MA-3000
Programming of the ADB-820H-MA-3000 module is carried out with our dedicated software using:
Module external programming probe – via ADP-9-USB, 4-pin programming probe.
While fitted inside the radio (Operational) – via the radios standard programming cable.

Installation of modules ADB-820H-MA-3000 – PlugIn module
For installation ADB-820H-MA-3000 Modules into Portable and Mobile Radios DP/DM3000 Series a special flex is additionally required as part of the radio interface.
