This board makes it possible to connect original instruments based on the ARINC 429 High Speed Bus to the flight simulator via LAN. The board has a single transmitter unit and has been developed as a LAN version for the “ARINC 429 HS Transmitter, USB”. Instead of selecting a fixed profile as before, you can freely select the data you need and want to send from a list in the software. This means that several devices can be operated in parallel on the board without having to create a new special profile.

The board also has a generator for a 400 Hz alternating voltage, which can be varied between 0 and 5 V (RMS) via the software. The lighting of most devices can be operated with 5 V DC without any problems. However, some devices require an AC control voltage to operate and vary the lighting. These are the APE-5100 clock, the DCDU and the full-format printer (Widebody). Similar to other boards, the data source can be selected and a value table can be created for calibration. A total of three connections are available for the voltage (AC signal and ground).

Please note that the output power is only designed as a control voltage for the above-mentioned devices. The circuit board cannot be used to control incandescent lamps.

An external 5 volt power supply is required.

Dimmer expansion, max. 5 A, max. 28 V

A virtually endless number of dimmer expansions can be connected in series to the dimmer board using a ribbon cable. The dimmer board transmits the brightness signal via the cable to the expansions, to which lamps (max. 28 V, max. 5 A) and their power supply (max. 28 V) can be connected as normal, as with the dimmer board.

This means that an infinite number of sub-dimmers with different voltages can be controlled with one potentiometer on the dimmer board.

All grounds of the power supplies of dimmers and expansions must be connected.

Dimmer, max. 5 A, max. 28 V, can be switched off via input

With this dimmer, all lamps (max. 28 V) that can be dimmed using pulse width modulation (PWM) can be dimmed between 0 and 100 % (e.g. LEDs or small light bulbs). The lamps and their supply voltage (max. 28 V) can be connected via two separate screw terminals. The load must not exceed 5 A.

The board has an input that can be used to switch off the dimmer. In this case, the connected lamps are extinguished. Ground must be connected to the input for this. In any case, the dimmer requires its own stable 5 V power supply. This should not be subjected to a high PWM load.

The brightness can be adjusted with a potentiometer (100 Ohm to 1 Megaohm), which is not included in the delivery contents.

The board also has a connection for dimmer expansions, which can be used to control other lamp systems, including those with different voltages, via the same potentiometer on this board (see “Dimmer expansion”).

Potentiometer not included in the delivery contents.

An external 5 volt power supply is required. All grounds of the power supplies of dimmers and expansions must be connected.
