Additional Information

Expanded HSI Navigation Interface: While all of Dynon's EFIS instruments currently include HSI functionality, full compatibility with some GPS and NAV radios has been limited by the serial connection method.

The HS34 overcomes these restraints by adding ARINC-429 and serial interfaces to cover many popular radios. With the addition of an HS34 to an EFIS, full compatibility is now possible with radios such as the Garmin 430/530. This includes advanced features IFR pilots demand, such as CDI auto-scaling and full vertical guidance information from WAAS-enabled units. The HS34 effectively eliminates the need to install a conventional CDI/GS head.

Superior User Interface: The front panel provides dedicated controls and indicators that optimize the pilot’s control over the HSI. The controls are backlit to facilitate night flight conditions. Separate knobs are used for setting the Heading, the Course (OBS) or entering general purpose Values. Other controls include NAV and Bearing Source buttons that facilitate independent selection over each input. Pilots receive feedback of the currently selected navigation source type from separate GPS and NAV indicator lights.

Expanded D10/D100 Series EFIS/EMS Capabilities: In addition to expanded HSI functionality, the HS34 also provides several powerful features to interconnected Dynon instruments that include:

• Use of the Value knob for adjusting the EFIS barometer, bugs, and timers.
• A built-in light level sensor to automatically adjust the LCD screen brightness
• Synthetic voice alert messages available for input to an intercom
• Additional EMS general purpose and contact inputs

Network Link to Dynon’s Instruments:The HS34 expansion module is network connected via the Dynon Smart Avionics Bus (DSAB). This two-wire connection not only simplifies wiring but extends individual module benefits to multiple interconnected Dynon instruments.
