GP-Wiz 49 with modular panels
markrvp:
What inputs on the GP-Wiz 49 do you have the 8-way joysticks mapped to? I don't have a solution, I'm just curious how you hooked this up as I may want to do something similar.

So when you unplug your parallel cable, the GP49 suddenly gets no data, and thinks your stick is in the up/right position.

Good call. This is exactly what is happening here.
I'd also like to comment that this probably isn't the best approach for the swap. Swapping at the USB port is much safer.
Remember the old warnings on video game systems about swapping games with the power on? The electronic joysticks like the 49-way, P360, Suzo Inductive, etc, all use a real electronic controller to generate the on/off or binary data expected by the interfaces. A sudden surge caused by disconnecting or connecting the data and power lines in a random fashion (which is what happens when using a connector like a card edge or db-25) could cause damage to the interface or the driver circuit of the stick.
If you must do this, I recommend an extra switch to disconnect the power to the interface and stick before disconnecting the data lines.

If the gpwiz was in the cp and plugged into a usb hub in the cp then unplug the usb before dealing with the 49way. But if the encoder is located in the cabinet and plugged into the PC directly then it won't be easy which defeats the purpose of modular controls.
I'd do what Randy said, create an on off switch. In fact, create a power rail/plugs with a master switch. That way anything that requires power can get it, say if you have perfect 360 and 49way joys, along with a lit tball and buttons, etc...
If you did some ingenious engineering you could have it automatically switch on and off when inserting the module...
however, isn't switching or plugging the USB cable going to have the same effect as using the parallel port interfaces? You still turn on and off the power in a surge?

I misread what Randy said, sorry. He said power to interface, not joys. Randy, that possible since I take it you get power from usb. Do you have a way to add a switch for power on the board?
