NexGen Sim: Converting the Game Port to USB - Suncom Daul Throttles Quadrant - Part 3

23 Dec 2017

Well, here I am again so let you all in whats really going on. I need a dual Throttle Quadrant. As I have said before I have 2 of them.

So here is the PLAN:

Now I distrust USB as when it fails you cant trust the configurations anymore. So I will communicate via RS-485 between Arduinos, with the master node,

using NASA's EADIN Lite Protocol.

having an Ethernet interface, to talk to the simulator. So far I have 3 nodes:

Master: runs joystick and talks to the simulator via ethernet and talks RS-485 to the slaves
Slave.1: runs Throttle Quadrant, Gear Lever, and Gear Lights
Slave.2: runs Rudder and Brakes
Slave.3: runs Engine Start Panel, Computer Fail-Over Panel

Complete Disassembly. Toss the Base Cover and bottom, I will keep the upper arc. Desolder and remove all the wire from the switches, we don't need it. That should leave you with the following: The Left Shell Body The Left Shell Rear The Right Shell Body The Right Shell Rear The Right Switch Support The Top Cover and Wipers The 2 Throttle Bodies Long Bolt & tension arm (nut) 2 white spacers 3 wave washers Quadrant center plate Now Remove and Toss the stupid lever locks and fill the hole. I want to replace JS1 and JS2 with analog joysticks I want to lengthen the Power Lever Arms with some aluminum. I want to add "gates to the Power Levers, fuel shutoff, and turbo. I will most likely rebuild the Quadrant base to add room for gates and thicker arms.	Connector	Pins	Functions	D/A	Pins

I wonder if NZ still has the Aermaci Simulators sitting in Ohakea. Good catch looks promising.

Yes, Eadin lite looks good Im still messing about with paper. I haven't powered it up yet.

and a boneyard.. I wish. good scrap yards though, this is the biggest catch. PHOENIX2000 Lear Jet

EADIN looks like a very useful protocol.

Thanks for sharing it

You're right about USB and the need to be absolute about what is going on.

I imagine you'd have an absolute ball at the Aircraft boneyard and bring home home everythign you can.

Cheers
