Button wiring is the issue. Each of those 4 pins are buttons. They connect to the ground from the VPF main board. So in your pic you have
yellow/yellow/yellow/black

but in reality it’s

yellow/yellow/yellow/yellow to separate GND

If that makes sense

Mike T•2/7/25, 4:07 AM

Actually as per your pic is how it’s wired…….the pic I posted was from a pic I downloaded from somewhere else on this discord to help with how the connection between shift register and VP control board. My switches are all connected to ground in series and the other side of switches to respective input on Shift register sequentially. So if there is no other requirement to do, it must be either board faulty or I’ve connected something wrong???

On the 6 pin input connector I see 5 wires which is correct but it looks like they are in positions 1-5? Hard to tell so maybe not but are you sure that is all correct? Looks like it’s missing GND but maybe that’s on the screw terminal?

TheAmazinGreatOP•2/7/25, 4:16 AM

It looks like DI is connected for some reason.

TheAmazinGreatOP•2/7/25, 4:16 AM

Maybe I see a GND wire hiding back there.

Mike T•2/7/25, 4:32 AM

Here is a better pic……D1 is wired but goes nowhere as not used…..D0 goes to D1 on VPF board. I’ll recheck connection between boards again.

TheAmazinGreatOP•2/7/25, 11:47 AM

Ok I see it. If the buttons are as the drawing I posted and board to board is correct it has to be an issue with the grounding or the board to board connections. This might be a dumb question but is the GND used for buttons connected to the same GND used for the board to board connection?

TheAmazinGreatOP•2/7/25, 11:47 AM

A pic of the configurator debug tab with the debug grip option selected may help troubleshoot also.

hello everyone,
can you confirm to me that there will be no risks, because I am about to connect my rhino VPforce for the first time, with my meanwell 360w 16A only to power my rhino for the moment?

I have a 350w 14A meanwell with the rhino hooked up at 8amps and the rhino MFG at 4 amps, my understanding is that the device will only draw the amps it needs.

Hey Mike, I'm building a custom H135 cyclic right now and encountered the same issues. checked everything twice redid all my connection; I was able to measure 5v coming all the way through my buttons. What I didn't know; you need to apply 24v to the rhino too to have the button presses registered. I hope that fixes your problem as well!

TheAmazinGreatOP•2/7/25, 9:16 PM

I just spent the last hour on DCS messing with SRS binds on a hat switch of my stick with no power to the base other than USB connection.

TheAmazinGreatOP•2/7/25, 9:17 PM

Buttons should work with USB only.

FalconMechanics•2/7/25, 9:35 PM

Too be fair it didn’t make sense too me why I would need to power it up.

FalconMechanics•2/7/25, 9:35 PM

Maybe something to do with configuring when switching from joystick source? I came from loopback to the shift register

Dimexi•2/7/25, 11:58 PM

Hi, I bought a while ago the ffb kit with usb board and couple of motors. Currently (first try) the board beeps, the led flashes once and windows states that usb board not recognized. This was kept in the ESD bag until assembled to base.

Dimexi•2/7/25, 11:59 PM

board is rhino ffb board Rev 1.6

because of a stick extension, the stick base rests a little off center. how can i recenter this?

spring balance seems to be related to this but not quite the same thing?

Mike T•2/8/25, 5:31 AM

OK so I decided to take out the Shift Register and VPF main board out of my DIY collective and make up a test setup as per pic attached. This way no way there is any possible wiring issues. Just the one button to test. Nothing! no reaction to btn press.......zilch! Double checked wiring and continuity all good!

Mike T•2/8/25, 6:35 AM

Yes tried with motor connected as well.......see attached pics.......same result, No response to button press.....ZILCH! I guess the Shift register is faulty or something fundamentally not making sense here......Unless @walmis can suggest a fix I'll have to go and try to get warranty return (new item) or look at going with a Bodnar board....which I really don't want to do as the extensive wiring has been done for the shift register....really disappointing outcome.

When you select debug grip in the drop down, what does the debug tab show?

If you short the the DATA pin to GND on the 5 pin interface do all the buttons light up?

Mike T•2/8/25, 7:18 AM

Ok with just USB connected and on the VP main board shorting data in (D1) with GND causes 24 out of the 48 button positions to light up only.

Mike T•2/8/25, 7:23 AM

@walmis….FYI the Shift register is not connecting to any proprietary grip…….its connected to my own custom buttons and switches on my DIY collective …..

walmis•2/8/25, 7:31 AM

Okay, not sure - wiring looks correct, maybe the s/r is indeed faulty.
Can you try soldering a wire from GND to any of the S/R Dx pins - it should light up a button constantly for debugging.

walmis•2/8/25, 7:33 AM

If all else fails you can submit the order form for a replacement

Dracks•2/8/25, 8:23 AM

Hi! Quick question: since the new Firmware and update, I'm having a mini problem with the Taog Huey on msfs2024. I have a mini lag when I click my TR and it releases the force...I didn't have that before.
Now I've recalibrated my FLANKR and readjusted my various effects and parameters, but it still persists. I'd say it does that 99% of the time. And that's just with this helicopter.
If anyone has any ideas? Thanks

Dimexi•2/8/25, 8:45 AM

Mike T•2/8/25, 9:50 AM

Hi @walmis......not sure what you mean.....I gather Dx means any of the 32 pins on the SR....right? Is that not the same as wiring a switch between gnd and a pin ....like in the pics I showed above? Pressing the switch shorts gnd to pin (unless I misunderstand your request).......in which case no button in the configurator lights up.

Mike T•2/8/25, 9:52 AM

I also tested gnd pin on SR (red probe in diode mode on multimeter) and black probe to each data pin and i get 760mV. (as per following instructions: You can check if the pins are making contact on the grip side by following these steps:
1. set multimeter to diode test ( -⯈⊢ )mode
2. disconnect the JST plug, and with the multimeter red(+) probe touch the GND pin on the JST exposed pad
3. go through all other pins with the black(-) probe - it should read 500-800mV if not, it's not making contact it will read OL)

sydost•2/8/25, 10:09 AM

@walmis can you help with @Dimexi ’s problem?

Button wiring is the issue. Each of those 4 pins are buttons. They connect to the ground from the VP
