Axnes AS Section 1: PNG System Axnes AS has delivered the Polycon system to the rotary wing Search and Rescue segment for decades. The system is widely adopted in this segment. The PNG system is based on the functionality in the previous system, but enhances the functionality and performance based on user feedback. The PNG system incorporates the following main features: • • • • • • • • • • • • • • • • • Wireless extension of aircraft intercom system with significant range and robustness.
Axnes AS Through the handheld internal microphone, the system enables communication with the survivor/ground rescue party without helmet removal. Depending on the configuration and part number, the handhelds are equipped with a GPS receiver. The position of the handheld device may be polled by the PNG Base Station and presented on the PNG Control Panel in the aircraft.
Axnes AS • 1x BNC antenna port The BST30/35 base station supports up to two voice groups, relaying through to the intercom on two separate intercom interfaces. One of the interfaces can support a PTT line supplied from the BST30/35 to the intercom. The PTT line can be driven by the BST30/35 triggered by wireless communication, or it can be set up to replicate PTT keying from the handsets (remote PTT keying). The BST30/35 can relay position data from an GPS enabled PNG handset.
Axnes AS Charging time is expected to be around 3 hours, but depending on the surrounding temperature, charge time may increase or be disabled. Charging is disabled below 0°C and above 50°C. If temperature is below 10°C or above 40°C, the charge current is reduced, and additional charging time must be expected. 1.5 Headset The BST30/35 allows for connection of a headset to the base station. This allow for replication of the lost intercom port or standalone operation.
Axnes AS Section 2: Operation The PNG system consists of one PNG Base Station and one or more handheld radios. To make all units in the PNG system interoperable, each unit must be configured with compatible parameters. Configuration of the PNG system will imply setting of radio frequencies, defining groups and setting scrambling or encryption parameters. Multiple configurations may be stored on a device to support different operational modes.
Axnes AS • • • • • Logical name of the configuration Radio parameters (frequency, modulation, and channel bandwidth) Group subscriptions for receive Group subscriptions for transmit Configuration of remote PTT control (handheld activation of PTT from the PNG Base Station to the intercom) The different pre-programmed configurations can be selected at start or during mission from the BST30/35 menu system. Typically, there will be several configurations when different radio channels shall be made available.

Axnes AS 2.4 Power on/off The PNG BST30 will by default automatically turn on when power is applied either to external power or USB power. The BST35 will be turned on when the on-button is pushed (battery mode), or power is supplied through USB or external power lines. The system will conduct an initial in-built test, and any errors will be displayed. After power-up, the system loads the last used configuration and is ready for use.
Axnes AS Initial Scroll buffer SR search and rescue The display can show two letters at a time and implements scrolling of text to display longer strings. Most menu entries are therefore presented with a two-letter acronym, before the full menu name is scrolled. 2.7 Power on/off The BST30/35 is turned on by pressing the volume up/ON button. The BST30/35 will start up in the last used configuration/mode. At power up, the configured name of the unit is displayed.
Axnes AS handsets can connect to the base station. The vertical position of the dot indicates battery status for battery operated units. Battery full Battery low Power on and radio off mode: When the BST30/35 is powered on and in radio off mode (default power up state configurable) the unit will display a radio off mode. With the following symbol: The radio on off mode can be toggled by pressing arrow up and arrow down simultaneous for 2 seconds.
Axnes AS the following symbol is displayed (only BST35): Keylock: When operating the menu key in in keylock mode the following symbol is displayed. Transmit: When the BST30/35 is transmitting audio, the transmit status is indicated with a blinking arrow pointing upwards. Receive: When the BST30/35 is receiving, a blinking arrow pointing downwards is displayed.
Axnes AS 2.9 Adjusting headset volume Depending on the headset/helmet connected to the BST30/35, the volume may be individually set to preferred volume by using the volume up/down buttons. When the BST30/35 is power off-on cycled, it will start up with a default volume setting. 2.10 VOX / PTT mode The default headset mode can be set in the device configuration. If VOX is selected as default, when a headset is connected to the BST30/35, it will by default be set to VOX mode.
Axnes AS If the VOX trigger level is experienced too high by the user, it can be reset by either leaving VOX mode, entering the VOX Min menu or by disconnecting/connecting the headset (Note: By disconnecting the headset cable from the BST30/35, the water resistance is broken, thus should NOT be done in a humid environment). All three actions will reset the VOX trigger level to the configured VOX Min level. The VOX trigger level can be automatically adjusted to VOX Max level by entering the VOX Max menu.
Axnes AS The keys are unlocked by pressing OK and MENU simultaneously. Key lock is reactivated after 20 seconds of inactivity. When key lock is active, the following status information is available by pressing: Arrow up and down without headset connected: Current selected configuration/channel Arrow up and down with headset connected: Headset volume is adjusted Unlocking the keys will open the menu at last used menu entry.
Axnes AS 2.13 Menu The first push on the MENU button will activate the last used menu entry. The configuration up or down buttons are used to navigate the menu tree. The OK button will select the active entry or setting, and configuration up or down will increase or reduce the value of the selected entry. The MENU button will step one level up in the menu hierarchy.
Axnes AS Select configuration: The predefined configurations set up by the supplier or through the PolyConnect tool can be selected and loaded. 2.13.

Axnes AS Audio Feedback: The volume of the audio feedback can be set. Setting the volume to zero will disable audio feedback. The setting is persistent over a power off-on cycle. Headset: By default, the BST30/35 will detect the connected microphone type. It is possible to override this and set the microphone type to be unamplified or amplified electret, custom or low impedance dynamic mic. The setting is persistent over a power off-on cycle.

Noise reduction: Turns on and off noise reduction on the line interface. 2.14 Audio feedback The BST30/35 implements audio feedback on events that are of importance to the operator.
Axnes AS 2.15 Error conditions The BST30/35 will conduct an initial inbuilt test and any errors detected will be displayed with an error code in the display. If an abnormal condition is detected, an error code will continuously be displayed as: E[error code] where [error code] is a vendor specific number. A malfunction might be corrected by rebooting the system by switching the BST30/35 off and then on again.
