(XX1) COSPAS/SARSAT Beacon Decoder. BD406-(XX1) is a single block aircraft panel

mounted version of the decoder, PBD406-(XX1) is a portable version of the BD406 with

built-in battery and dedicated housing. This manual DV 16401.03 is a subset of

1.2 Purpose of Equipment

BD406-(XX1) / PBD406-(XX1) COSPAS/SARSAT Beacon Decoder is designed for use by

SAR authorities as a tool to provide vital information and assistance during rescue

missions. Usage of BD406 in SAR missions reduces the time required to locate a distress

signal, which has a direct impact on the probability of survival of the person in distress at

sea or on land.

The BD406 decoder/receiver provides immediate and direct detection of the distress

messages transmitted on 406 MHz (ELTs for aviation use, EPIRBs for maritime use, and

PLBs for personal use). It decodes the position of the transmitted signal, displays the

beacons relative position and allows continuous tracking during the rescue mission.

The International Satellite System for Search and Rescue (COSPAS-SARSAT) system is

described on

www.cospas-sarsat.org.

Figure 1-3 Battery charger for PBD406

The device is capable of receiving, decoding and processing COSPAS/SARSAT distress

signal captured within the signal range 406.020 – 406.081 MHz.

BD406 receiver is designed as a single block unit for usage in a cockpit environment of

any general aviation aircraft including helicopters.

BD406 dimensions correspond to the standard instrument diameter of 58 mm (2 ¼ inch).

It can be installed by means of four screws (rear panel installation). All controls and

indicators are located on the front panel. The equipment connectors and the antenna

sockets are located at the rear of the unit.

PBD406 receiver is designed as an autonomous portable version with its own battery,

internal speaker, battery charger and inputs for RX and GPS antennas.

1.4.1 Beacon / NavPoint Indication

In Mission Mode, which is the typical operational mode, the user has access to Beacon

and NavPoint views. Beacon view is related to the set of data received from distress

beacons during a mission.

The different data presentations of single beacon include: raw 15HexID, processed data:

(Protocol Type Standard/National Location, etc.), Beacon Type (EPIRB, PLB, etc.),

Beacon Serial Number, TAC (Type Approval Certificate Number), Beacon position (if

distress beacon has GPS functionality).

BD406

DV 16401.03 Issue 3 2/2013 Page 1-7

Up to 49 received beacons can be stored in internal memory. Access is available by

means of the Rotary Knob, and LEXCH / REXCH keys (refer to section 3.1 for controls

description). Beacon data can be removed from memory on demand. Refer to section 3

for menu details.

Figure 1-5 Menu screens available for NavPoints indication

Navigational data from beacon can be used to create NavPoint. NavPoint is a set of

navigational data (latitude, longitude, name, additional info) that can be stored in internal

memory (up to 49 records) and used to navigate to a chosen target. Basic operations over

NavPoint database are defined in section 3.

1.4.2 Beacons / NavPoint Memory

The device can store up to 49 Beacons and 49 NavPoints in internal nonvolatile memory.

Beacon memory can be erased at start-up of the device (refer to section 3.1.9 for start-up

sequence and to section 3.2 for Mission menus description).

1.4.3 BD406-(XX1) Power Supply

BD406-(XX1) has an operational power range of 9 – 32 VDC but start up (power-on) of

the device requires 10.5 – 32V DC. Once the device is operational the power supply may

be reduced to 9V DC.

BD406

Page 1-8 DV 16401.03 Issue 3 2/2013

1.4.4 PBD406-(XX1) Power Supply

PBD406-(XX1) power is supplied from an internal 12.0 V maintenance-free rechargeable,

sealed dry acid battery. The internal power module, installed inside the chassis, is capable

of operation within a 9 – 36 V DC range.

Estimated charge time for a depleted battery is approximately 8 hours. The charger

(Figure 1-3) can also be used as an external power supply; therefore there is no need to

disconnect the charger when the battery is fully charged. The charger can be safely left

plugged in. The nominal operating time on full battery charge is no less than 5 hours.

The battery is protected against a deep discharge – PBD406-(XX1) will not operate / start

when battery voltage is lower than 10.5V.

The battery should be charged every six months for long term inactive storage periods of

more than six months.

Note: Operating time of PBD406-(XX1) may decrease for ambient temperatures

below 0 °C.

1.4.5 Audio Outputs

The receiver includes two audio outputs: Headphone and Speaker. The Headphone rated

output power is 300 mW into 150 Ohms. The rated output power from the Speaker Output

is 4 W into 4 Ohms.

1.4.6 Illumination

The illumination of LCD and push buttons can be controlled either internally from the front

panel knob or externally via the dimming inputs. In case of external dimming for BD406-

(001) / PBD406-(001) illumination curve (brightness to voltage relation) can be adjusted in

the Installation Setup. For BD406-(011) / PBD406-(011) the illumination curve cannot be

set. In case of PBD406-(001) and PBD406-(011) - DIMMING INPUT shall be set in

Installation Setup to range 0…14V (refer to section 2.4.5).

Note: Illumination of BD406-(XX1) / PBD406-(XX1) is automatically switched off

when the power supply voltage drops below 10.5V.

1.4.7 Audio Notifications

BD406-(XX1) / PBD406-(XX1) is equipped with a voice notification system that informs

the user about:

• incoming COSPAS/SARSAT messages,

• homing – distance and bearing to the chosen target (message is triggered on

demand by Rotary Knob or dedicated discrete input),

• the device failure.

Refer to section 3.1.5 for details.

BD406

DV 16401.03 Issue 3 2/2013 Page 1-9

1.4.8 Internal GPS Receiver

BD406-(XX1) / PBD406-(XX1) is equipped with an integrated GPS receiver module LEA-

6S manufactured by u-blox. The additional information regarding the GPS receiver can be

found on www.u-blox.com.

BD406-(XX1) / PBD406-(XX1) is capable of routing GPS data in ASCII format (NMEA

0183 compliant) from the internal GPS receiver via RS232 interface. Refer to section

2.3.3.15 for details.

CAUTION: Active GPS antenna should only be connected to the BD406-(XX1) /

PBD406-(XX1) when the receiver is not powered.

Do not connect or disconnect the GPS antenna when the PBD406-(XX1) is running

as the internal GPS receiver calibrates the noise floor on power-up.

Connecting the antenna after power-up can result in prolonged

acquisition time.

Use ONLY active antennas according to specification from section 1.6.9 GPS

Antenna Specification.

Passive GPS antennas shall not be connected to the GPS TNC input.

1.4.9 Built-In Tests

After being switched on, the unit performs a self-test (PBIT). In case of errors the device

will notify the user about any malfunction. During PBIT the receiver identifies itself and

displays the corresponding software versions of the Control Head and Chassis Module.

During normal operation a continuous built-in test (CBIT) verifies the correct operation of

the unit in background. In case of problems an error notification is displayed (refer to

section 3.1.6 for warning and error description).

1.4.10 Installation Setup

Configuration of the installation parameters such as headphone and speaker activation,

GPS source, illumination level, and further parameters is possible during Installation

Setup.

1.4.11 Service Mode

Special factory configuration of the system is possible in Service Mode via a RS422

interface with a proprietary serial data communication protocol.
