Transponder / ADF
This Module is a combined Transponder- and ADF-Control Unit, which is very useful for both General Aviation and Airliner-Cockpits.
Transponder (XPNDR)
The left part of the Module is used to set the transponder code ("squawk") as well as the operating mode (Standby or Mode C). Additional buttons are provided to set the SPI-bit in the transmission ("Squawk Ident") or to quickly set a predefined default code, for example when leaving radar controlled airspace.
Automatic Direction Finder (ADF)
The ADF is the on-board equipment for radio navigation using NDBs (Non-Directional Beacons). Similar to the COM/NAV modules, the standby frequency can be tuned and switched with the active frequency using the toggle button. An additional button is available to enable the audio identifier, to check if the correct ground station is received.
MCP (Mode Control Panel)
The MCP-Module represents a Boeing 737 Style Mode Control Panel, which is sometimes referred to as "the Autopilot". It consists of two side-by-side Avionic-PCBs.
Modules
Every module in the system has its own ATMega microcontroller from the ATMELs AVR Series, which is a tiny but powerful controller. It operates at 16Mhz, processes all the digital in- and outputs and handles the communication to other modules and the SIM-MODULES Control Panel.
MAIN-Module
AVIONIC-Module
This module consists of 2 PCBs which are mounted back-to-back, one front- and one controller PCB. The electronic layout is designed in a way which allows the assembly of different modules with different functionality - the placing of the front components, like 7-segment displays, buttons or LEDs can be done flexibly as desired. By setting a DIP-switch on the back, the module will know which data is needed and the appropriate functionality will be automatically provided.
So, using the same PCBs, the following modules can be assembled:
Other Modules
Of course, using different PCB designs or other wiring techniques, any other module can also be realized on request - for example highly realistic replicas of real aircraft avionics. The only limitation is the maximum number of components that can be used per module:
- 64 digital inputs (e.g. pushbuttons or switches)
- 64 LED outputs
- 8 rotary encoders
- 24 seven-segment LED displays
