The Emsis system is a set of complex electronics devices and we strongly recommend to carefully read this manual before installing and using the system. Emsis is a name for a line of flight instruments which can be used as: primary flight display (PFD), engine monitoring system (EMS).
Emsis — Manual 2.1 Command Panel Command Panel Emsis instruments come in two physical sizes. The first one is a standard aviation size, which is 80 mm diagonal, while the second one is non-standard and is characterized with a 3.5” screen diagonal.
The power ON/OFF button is normally not used. However on some Emsis instruments, it is used to turn the instrument on/off. Note that 3.5” screen Emsis does not have the power ON/OFF button. The close button serves as the close or cancel command.
2.3.2 Copying New Software to Emsis To copy the software from the SD card to Emsis follow these steps: 1. Insert SD card with the new software (Update.kus) into Emsis SD card slot. The contacts on the card must face upward.
file integrity is verified and in the second step the file is copied into Emsis. 4. Once finished, Emsis will start with the new software. The very first start after the update takes slightly longer. The Start normally option is used if you changed your mind and...
file. Layouts are prepared by Kanardia and sent to users when requested. Follow the steps below in order to copy a new layout to Emsis. 1. A layout file is usually sent by e-mail to the user. Copy the file to the micro SD card.
Emsis — Manual 2.5 Technical Specifications 7. Close all windows. Emsis will reboot with the new layout ac- tive. Technical Specifications Tables 1 and 2 illustrate some general instrument specifications for each instrument size. CAN Bus The Emsis system can be easily extended into a much more complex form, shown in Figure 3.
AHRS provides attitude, position and velocities. AHRS unit is hidden inside Emsis PFD unit. Emsis unit – presents all relevant information that appears on the CAN bus in a pilot friendly form on LCD screen. Most of this manual describes how to access, read and interact with the Emsis display.
GPS position. Again, Kalman filtering is used to obtain the final solution. When engine monitoring unit (Daqu) is present on CAN bus, Emsis PFD can also show relevant engine and fuel information. When maps are enabled and licensed, Emsis PFD can also show raster maps on graphical display.
Emsis display. Figure 4: Illustration of Emsis EMS configuration When AHRS unit is present on CAN bus, Emsis EMS can also show flight information on graphical display, too. When maps are enabled and licensed and AHRS unit is present on CAN bus, Emsis EMS can also show raster maps on graphical display.
More about Daqu unit and engine sensors is written in Daqu Instal- lation Manual. Screens The Emsis unit can toggle between several main screens depending on your Emsis type: Primary flight display (PFD) screen – artificial horizon with air data.

Figure 5. It will take the current pitch and set it as zero pitch. The change is not immediate and it takes ca. 5 seconds for AHRS unit to accept it. Once Emsis is switched off, this setting is forgotten.
The Primary flight display (PFD) screen is illustrated in Figure 6. It displays artificial horizon with flight data information. Figure 6: Emsis primary flight display screen PFD screen consists of the following items: Quality of the GPS fix. Three green bars mean 3D fix, two yellow bars are 2D fix and cross means no signal from GPS.
(12 degrees per second). Engine Monitoring Screen An example of engine monitoring screen is illustrated in Figure 7. It can be designed differently for each Emsis unit regarding to the wishes of the customer. Additionally, more than one EMS screen can be configured.

Emsis — Manual 5.2 Engine Monitoring Screen This is just a subset of options. Emsis can also display: rotor RPM, pneumatic pressure, trim positions, gearbox temperature, carburetor temperature and much more. Additionally, the engine parameters can be mixed with flight parameters. So, you can see the altitude, airspeed, QNH, etc.
Maps Screen The Maps screen is illustrated in Figure 9. Maps can be shown on Emsis only if GPS information is present on the CAN bus. Emsis PFD supports this by default, while other versions depend on units that are connected to the CAN bus (Nesis, some other Emsis PFD, Horis, etc.).
Once you have a map on the micro SD card, do the following: Insert the SD card into Emsis with the contacts facing up. Select the Setup screen, Maps Copy Maps option. If asked, enter standard password 314.
Figure 10: Copying maps (left) and maps info window (right) 5.3.5 Information In order to see which maps are loaded into Emsis internal memory, select the Setup screen, Maps Maps Info option. A list of maps appears. If you have a lot of maps loaded, there may be a delay.
5.4 Emsis Setup Screen Emsis Setup Screen The Emsis Setup screen allows you to access or set several options. It is accessed by pushing the screen selector button. Figure 11 illustrates the screen. The displayed options depend on the hardware detected on the CAN bus.

Please make sure that airplane is level for both, roll and pitch. Make also sure that Emsis unit is turned ON for at least five minutes – this warms up the internal electronics and stabilizes numerical filters. Once the airplane is level and steady, select the AHRS level option to start the automatic calibration procedure.

outside air temperature (OAT) sensor installation. Installation to the Instrument Panel This section covers the installation of the Emsis unit. Emsis 80 mm version is presented (standard avionics unit dimension), while the same principles apply for the Emsis 3.5” screen version.
Emsis Back Panel Connectors and Cable Clearance Emsis units are divided into two main groups (according to the back panel), Emsis with AHRS unit built-in and all the others. Here is a brief description of individual connectors from Figure 28: Figure 28: Emsis unit with AHRS built-in (left), Emsis slave unit (right).
Page 53
Emsis 3.5” screen version requires similar clearance space. Emsis PFD is shipped with a connector inserted into one CAN port. It is a 120 Ω network terminator resistor to start and terminate the network. When Daqu unit is connected, terminator can be disconnected.
Figure 29: Side photo of Emsis 80mm version with all cables con- nected Connection to the Electrical System The Emsis unit must be connected to a 12 V DC standard aircraft power source. Additionally it can be connected to the backup battery – UPSU unit.
When you use more than one Emsis unit in the cockpit, other Emsis units get power via CAN cable. On our website you will find connection schema for Emsis unit with or without UPSU unit.
Emsis — Manual 6.4 Outside Air Temperature Probe Installation Outside Air Temperature Probe Installation Although the OAT probe is a simple element in the Emsis PFD system, its installation requires some attention. Outside air temperature (OAT) probe is shipped with the Emsis PFD unit.
In standard configurations with Emsis PFD, one CAN port is con- nected to terminator, while the other is unused or connected to other Emsis unit. One CAN port may be used to connect with Daqu (en- gine monitoring unit), in this case terminator can be disconnected.
Emsis — Manual 6.6 Connection to the 485 Network Connection to the 485 Network The RS-485 connector is obsolete. It was used to connect devices via 485 protocol. It will be replaced by RS-232 connector in forthcoming versions. GPS Antenna Installation...
Software Tank The software tank is active when no fuel level channel is configured in Daqu. Emsis allows you to enter the current amount of fuel and this amount is then reduced in time based on fuel consumption. The fuel consumption is either calculated or measured. Measured fuel consumption usually gives better results assuming that a high quality fuel flow sensor is applied.
Emsis — Manual 7.2 Hardware Tank Figure 31: Software (simulated) fuel tank level adjustment Hardware Tank Hardware tank is based on fuel level sensors. First you need to con- nect sensors to Daqu and activate/configure appropriate channels. Once this is completed, you can continue with tank calibration.
Fuel level volume value on the CAN bus is always represented in liters. Hence the complete tank calibration process must be done in liters. Emsis will ignore the volume unit setting and always consider the numbers you are entering as liters.

Emsis — Manual 7.2 Hardware Tank position differences. It gives good results, when sensor behaviour is predictable (read relay based sensors, for example) or in serial production, when sensor are installed with high precision. This procedure requires two steps. In the first step, the tank shape is selected and in the second step, sensor value for empty (min) and full (max) condition is given.
