No feature improvements or bug fixes for this product specifically. However, it must be updated to work with other 5.4 products.

Support Program Only: Improvements to support firmware upgrades in OEM installations such as Vans Aircraft that use locked settings files to distribute settings during firmware updates. All other customers unaffected. There has been NO CHANGE to the underlying firmware files from 5.3.

No changes for HS34. Upgrade still required to communicate with other DSAB devices running version 5.3.

Improved: Autopilot GPS-to-HDG mode drop-downs reduced when GPS data goes momentarily bad.

Fixed: Heading shaking and accuracy issues that could occur in some installations. Please note, the installer may need to recalibrate after upgrade.

Fixed: GRT oil temperature error at high temperatures.

Added: Support for SkyView conversion. Please note, for existing servos in the field you must upgrade to Version 5.2 before connecting to a SkyView system.

5.1

5/26/09

Added: Display of the value knob (HS34 or AP74) setting box on all DSAB peers.

Fixed: Holding the heading knob on an HS34 did not toggle the heading knob off.

Fixed: SL30 BTS now correctly reflects standby radio bearing

Fixed: Pressing and holding the COURSE knob would not properly sync the course pointer to the current bearing. Instead it would sync to 360.

5.0

11/12/08

Fixed: Alert on HS34 contacts now works correctly.

Fixed: HS34 not handling positive mag var correctly.

Fixed: Pushing BRG SRC would not always allow the bearings to be adjusted.

Fixed: Screen brightness could be "stuck" at a very dim setting if an HS34 was present and then went offline.

Fixed: Serial inputs (GPS/SL30) connected to a screen when an HS34 is also connected will be properly ignored with fail-over if the HS34 fails.

Fixed: SL30 BTS reflected BTA value.

Fixed: Voice alert test behavior fixed when tested from an EMS product with an HS34 installed.

Improved: Garmin 480 GPS/NAV compatibility.

Improved: HS34 VALUE knob functionality updated to match AP74. See: EFIS > SETUP > HSI > VALUE KNOB. Can set REQUIRE PUSH to prevent unintentional changes to ALT or BARO mode. Can set FIRST ACTION to set the first parameter (ALT or BARO) in button push rotation. Bugs can be set without entering BUGS menu. Removed IAS bug from the values affected by the VALUE knob. A pop-up value window appears when adjusting a value with HS34.

Improved: Malformed AvMap NMEA data should be handled better, resulting in magnetic variation being back-calulated from other values when it is not explicitly set. This allows a correct magnetic bearing and course to be displayed. AvMAP must have NMEA set to "processed."

Improved: Pressing HEADING knob button no longer toggles the HDG bug on/off. HEADING button press now acts as a SYNC of HDG bug to current heading. Pressing and holding HEADING toggles the heading bug on.
