Components such as the sidestick, rudders, spoilers and flaps panel can be wired up to a joystick board such as the Leo Bodnar BU0836A. If no transducers are present, an interface must be built to translate physical movements to an electrical signal which the computer can read.
For the outputs, an I/O solution which can drive the korry bulbs is required.
Other OEM components such as the ECAM Control Panel, ATC/Transponder Panel, Audio Control Panel, Rudder Trim Panel and DDRMI require specific boards which can read and output ARINC429.
This page lists the different types of Airbus hardware and the available interface solution.
Updated February 2019
| Hardware | Solution |
Korry push buttons and annunciators
| Requires an interface board (I/O) board which is compatible with the Flight Simulator and avionics software. Solution requires a board which can output 5 VDC at 0.115 A per korry bulb.
Existing boards such as those available from Flight Deck Solutions and OpenCockpit do not provide the necessary current to drive the korry bulbs. A Darlington or DMOS transistor can amplify the current. The Soarbywire Output amplifier solution is also available and can output to the incandescent bulbs. |
Flight Control Unit (FCU) and Unit
| Requires 28 VDC power supply and 5 VDC integral and display backlight. Interface solution available from Cockpit Concept. Their FCU interface board allows you to interface the hardware to avionics software. |
Multi-Function Control and Display Unit (MCDU)
| Native usage requires ARINC 429 interfacing by Cockpit Concept and 115 VAC for operation. Alternatively MCDU keypad can be integrated with an LCD and I/O board; Simulator Solutions offers a conversion kit for such a purpose. |
Lighting
| Panel backlighting is achieved with 5 VDC. Glareshield floodlights require 28VDC. Lighting can be interfaced with the SimStack output boards or Cockpit Concept dimming solution. |
Electronic Clock
| Clock time can sync to Flight Sim time using Cockpit Concept ARINC429 Low Speed boards and requires 28 VDC. |
Radio Management Panel | RMP requires 28 VDC and a low speed input ARINC 429 board. |
ECAM Control Panel | ECP requires either a low speed or high speed ARINC 429 transmitter board and 28 VDC for Interfacing.
Direct wiring to an interface board, bypassing ARINC 429 is also possible. |
Rudder Trim Indicator | The rudder trim indicator on the parking brake panel requires either a low speed or high speed outout ARINC 429 board and 28 VDC. |
Sidesticks | Direct canon pin output to a joystick board. 28 VDC to be supplied to the solenoid to lock the sidestick when A/P is engaged. |
ATC/TCAS | ATC/TCAS requires 115 VAC to operate and ARINC 429 interfacing. |
Audio Control Panel | Audio Control Panel requires 28 VDC to operate and low speed ARINC 429 interfacing. |
Flaps Panel | Direct canon pin output to a joystick interface board. |
Speedbrake/Spoilers | Direct canon pin output to a joystick interface board. |
Sidestick Solenoid | 28 VDC required for sidestick solenoid operations. |
Triple Brake Pressure Gauge | Cockpit Concept Analogue voltage board |
Rudder Pedal Brake Transmitter | Direct canon pinout to a joystick interface board |
Weather Control Panel
| Requires 28 VDC and ARINC 429 interfacing |
Digital Distance and Radio Magnetic Indicator | Requires 115 VDC and Lo and Hi speed ARINC 429 interfacing |

Gooday Ben, you are doing a great job on the Airbus. I wish I had been able to buy real parts when I started back in 1999.
Congrats on having such a nice site here, I have only just started seeing it again.
Cheers…………..Brian W.

Hello Ben,
could you tell me how you solved the problem to supply the parts with 115V400hz?
Im struggling to find a solution, especially because I don’t wanna destroy parts and it could be dangerous with this Voltages.
Kind regards
Michael

Hi Michael,
You will need to purchase a single phase static inverter – you should be able to find one on eBay; they take 28 VDC as the input and output 115 VAC 400 hz.
