5.1

5/26/09

Note: It is no longer recommended that Keep Alive be connected EFIS and EMS products.

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

Fixed: A display problem with the EMS flaps info item.

Fixed: Display problems on the Fuel Computer page when tank name AUX is used.

Fixed: TRPRST button did not appear on TIMES page.

5.0

11/12/08

Added: Ability to configure an EMS contact input as a stall indicator. If AOA selected as alarm type, then audible stall warning triggered on contact activation. See: EMS > SETUP > EMS CONTACT 1/2 > ALARM

Added: Ability to perform incremental data log downloads.

Added: Alarm light output (pin 29 on EMS D-37 connector) can be repurposed as a dim control for other devices in aircraft. The dimming output is directly tied to the brightness of the screen, configured in the DIM menu. See: EMS > SETUP > GLOBAL > ALARM CONFIG >  LGT BHVR.

Added: Support for new actively powered oil pressure sensor that comes preinstalled on newer Rotax 912 motors.

Fixed: Contact state indications reversed.

Fixed: Coolant pressure units mismatch.

Fixed: If MAP and/or RPM are set to DISPLAY: OFF in EMS, they will not display as EFIS info items. See: EFIS > INFO > ENGINE and EMS > SETUP > SENSOR > TACHOMETER/MANAIFOLD PRES > DISPLAY.

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

Fixed: Tach time accumulation was wrong in some instances when the left and right PULSES/REV settings were different.

Fixed: Timers now sync correctly across DSAB.

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

Improved: DSAB status messages improved to include ACTIVE, UPGRADE REQ, LOST PEERS, STANDALONE, and OFFLINE. See: EFIS > SETUP > DSAB > STATUS

Improved: EFIS and EMS loading screens display more helpful information and support phone number.

Improved: Modified percent power calculation for Lycoming and Continental engines to account for engine RPM red line, not compression ratio. When EMS > SETUP > GLOBAL > ENGINE TYPE is set to LY/CON, then the Tachometer HI RED/YEL parameter is factored into the percent power calculation. See: EMS > SETUP > SENSORS > TACHOMETER > HI RED/YEL.

4.2

7/3/08

New build with EFIS changes only

4.0.4

4/9/08

Fixed: Vulnerability during power down on EMS-D10 and EMS-D120

4.0

10/15/07

Added: 1/3 HSI on left, 2/3 EMS on right screen combination.

Added: EMS GP input can now accept an OAT for monitoring a user-named temperature.
See: EMS menu>SETUP>SENSORS>EMS GP INPUT>GP TEMP

Added: EMS General Purpose Thermocouple input can now accept a type J or K thermocouple for monitoring a user-named temperature.
See: EMS menu>SETUP>SENSORS>GP T-COUPLE

Added: 1/3 EMS on left, 2/3 EFIS on right screen combination.

Added: Support for HS34 HSI Expansion module.

Improved: EMS can now use GPS altitude for % power calculation.

Improved: EMS data can now be logged internally at 1, 10, 30, or 60 second intervals.

Improved: Serial GPS input compatibility improved with multiple devices. See http://wiki.dynonavionics.com/GPS_Configuration_Settings for current compatibility notes.

Improved: DSAB updated to handle all communications between Dynon Avionics products. PC serial ports no longer need to be connected between EFIS and EMS units as previously required. All data and device features, except for setup functions, can now be used from any connected screen.

Improved: When the Rotax 912 engine pre-set configuration is selected via EMS menu > SETUP > GLOBAL > ENGINE TYPE, tach time is not displayed since it is not a meaningful measurement on Rotax engines. Tach time is still available when the Rotax configuration is not selected and engine parameters are configured individually.

Fixed: EMS systems displaying heading information from a connected EFIS now correctly alert if heading is lost.

Fixed: Coolant Temp Sensor Type 4
Fixed a characterization error which caused the EMS to display incorrect readings for coolant temperature sensor type 4 (Rotax 801-10-1)

3.0

7/11/07

Added: Type 4 coolant temperature sensor.

Added: Leaning mode fuel flow difference.
See: EMS menu>LEAN

After the last cylinder peaks during a leaning operation the difference in fuel flow between the first and last cylinder peaks is displayed. If the fuel flow decreases it is shown as Lean of Peak. If fuel flow increases it is shown as Rich of Peak.

Added: Fuel addition auto detection.
See: EMS menu>SETUP>FUEL>ADD THRESHOLD

If enabled, at power-up an EMS will detect if fuel has been added above a percentage of the total tank volume in any tank. If detected, the EMS will prompt the pilot to add fuel on the fuel page.

Added: EMS end-user data logging.
See: EMS menu>GLOBAL>DATALOG CONFIG

The EMS saves many parameters for later retrieval by the Dynon Support Program.

Added: Percent power calculation.
See: EMS menu>SETUP>GLOBAL>ENGINE TYPE and HP RATING.

If enabled, percent power is displayed in the color arc of the manifold pressure guage. If a fuel flow sensor is installed, then lean or rich of peak operation is automatically detected. An altitude input from an EFIS is required.

Added: Save settings on power-off.

In addition to the current logic, units will now save their settings when powered off with the front panel button.

Added: Menu restore after alert acknowledge.

If navigating in the menu system and an alarm bar is raised, the current state of the menu is restored after the last alarm is acknowledged or cleared.

Added: Setting tach and hobbs times tenths.
See: EMS menu>SETUP>GLOBAL>SET HOBBS TIME and SET TACH TIME.

Tach and Hobbs times may be set in tenths of an hour.

Added: Engine parameter display on EFIS main page.
See: EFIS menu>INFO>LEFT or RIGHT>ENGINE

Added an EFIS info item to display engine RPM and tach if available.

Added: Fuel flow dial display.
See: EMS menu>SETUP>SENSOR>FUEL FLOW

Where possible the digital only fuel flow indicator was swapped with the analog fuel pressure indicator.

Added: Fuel flow info item.
See: EMS menu>SETUP>GLOBAL>INFO ITEM CONFIG

Added: User configuration of serial ports.
See: EFIS menu>SETUP>HSI>EFIS_SERIAL or EMS menu>SETUP>GLOBAL>EMS SERIAL.

An HSI Setup menu was added. This menu makes it possible to override the auto detect feature of the local serial port.

Added: Minimum red line on tach.
See: EMS menu>SETUP>GLOBAL>ENGINE TYPE: ROTAX

Added a minimum red line setting for Rotax engines.

Added: Minimum red line on oil temperature.
See: EMS menu>SETUP>GLOBAL>ENGINE TYPE: ROTAX

For a Rotax engine the oil temperature's arc colors are dynamically set to the fixed values defined by the manufacturer's recommendations.

Improved: Flight time reset.

The flight time is saved and preserved across a power cycle. It is reset when the oil pressure exceeds 15 PSI for the first time after power-up.

Improved: Leaning mode temperature display.

The temperature drop reading of a cylinder now supports 3 digits so that LOP or ROP temperatures above 99 degrees can be displayed.

Improved: Fuel used reset.

Instead of reseting the fuel used at power up, the fuel used is saved and preserved across a power cycle. It is reset when the oil pressure exceeds 15 PSI for the first time after power-up. This means the pilot may record the value at any time prior to the next flight.

Improved: Fuel pressure redline increments.
See: EMS menu>SETUP>SENSOR>FUEL PRESSURE

The fuel pressure color thresholds are now setable in tenths.

Improved: Oil pressure digital display.

Oil pressure display now supports three digits.

Fixed: EFIS not detected alert.

When an EMS loses communication with an EFIS the alert is now displayed properly.

Fixed: Canceling flap calibration process.
See: EMS menu>SETUP>FLAP

It is now possible to cancel flap calibration process before completion without affecting any currently saved calibration.

Fixed: Type 2 ammeter display.

Removed a communications glitch that caused the type 2 ammeter display to go to 99 periodically.

Fixed: EMS data output.

Fixed a problem with the EMS serial data output for general purpose inputs.

Fixed: Lowrance GPS integration.

Fixed: EGT span and shock alarm display.

Fixed a problem where EGT span and shock alarms would not trigger the light.

Fixed: Distance to waypoint units.

The distance to waypoint display was using the wrong setting when deteremining units.
