7.17 Software And Security
Venture incorporates security features to protect the device from cloning and
against software piracy. These features are:
1. DLL protection by password — this prevents a third party from using IDS to
reconfigure parts.
2. Hybrid authentication by 128-bit fingerprint to identify parts in application
software — this prevents a third party from cloning a device's EEPROM, since
the fingerprint can not be overwritten. Special functions can be used in fitting
software to reject parts that do not match the expected fingerprint. This will
prevent the piracy of fitting software.
3. DLL to hybrid pairing by using a software key in ARK to match product libraries
with client software. A part can be "locked" at manufacturing time so that it will
only communicate with the library it was programmed with. This prevents a
third party from potentially upgrading a device with a different library in IDS or
other application software.
Full software support is provided for every stage of development from design to
manufacturing to fitting. Please refer to the
Getting Started with ARK Guide
,
document #27217.
7.18 SDA Communication
Venture is programmed via the SDA pin using industry standard programming
boxes. During parameter changes the main audio signal path of the hybrid is
temporarily muted using the cross fader to avoid the generation of disturbing audio
transients. Once the changes are complete, the main audio path is reactivated.
Any changes made during programming will be lost at power-off unless they are
explicitly burned to EEPROM memory.
Improvements have been made to the ARK software for Venture, which will
increase communication speed. Certain parameters in ARKonline can be selected
in such a way as to reduce the number of pages that need to be read out.
7.19 Power Management
Venture was designed to accommodate high power applications. AC ripple on the
supply can cause instantaneous reduction of the battery's voltage, potentially
disruption the circuit's function. Venture hybrids have a separate power supply and
ground connections for the output stage. This allows hearing instrument designers
to accommodate external RC filters in order to minimize any AC ripple from the
supply line. Reducing this AC ripple greatly improves the stability of the circuit and
prevents unwanted reset of the circuit caused by spikes on the supply line. For
more information on properly designing a filter to reduce supply ripple, please refer
