try rescan devices button within DCS?

PPriest try rescan devices button within DCS?

While this may help it register within DCS, I don't think it will solve the primary problem, that of freezing DCS at the splash screen.

1st suggestion is to look at the DCS log to look for errors when it is initializing the joystick devices
Barring any obvious errors in the log....
- if its on a USB hub, try direct attach to PC
- remove any mods
- slow repair DCS

Looks as if I've fixed it. I rolled the software back to the prior Beta version, and it's been working since. Not sure if there's something wrong with that .2 beta version software, but there certainly seemed to be, for me

Recent rhino install in dcs, all has been fine till tonight it would suddenly “beep” and shut off. Did it every 10-15 mins. On debug page see undervoltage error:

Comes back after cycling the red button.

I had TelemFFB working fine, and then I installed Simhub and it stopped working. I get no telemetry data from DCS, and from what I can tell the export.lua file seems to be set up correctly. Feels like I'm missing something, can someone point me in the right direction? I'm getting a lot of this in the dcs.log: 2025-01-26 10:37:26.516 ERROR Lua::Config (Main): Call error LuaExportAfterNextFrame:[string "C:\Users\nikla\Saved Games\DCS.openbeta\Scripts\DCS-BIOS\lib\io\UDPSender.lua"]:30: attempt to call method 'send' (a nil value)

Hi I received my VP Force Rhino a month or so ago and broadly it's great. The only problem I'm having is with the VKB Adapter I bought to go with it: I'm finding that sometimes the buttons in my VKB Gunfighter MCP work okay .. but sometimes they don't. The VKB Gunfighter MCP stick works perfectly on its own VKB provided base, so that doesn't seem to be the issue. I've tried really seating the gunfighter into the VKB adapter as best as possible and really screwing it in tight so it doesn't move at all and have issues with the contacts. However, I'm still finding it very unreliable. My sense is the adapter is not making good contact with the 3 pins on the stick and so is cutting in and out. I've tried cleaning the contacts on the adapter with a cloth, but that doesn't seem to have helped much either.

Is this a known issue? Is there a way to fix it? Or should I seek to return my VKB Adapter as defective and get a replacement?

Vakarian•1/26/25, 4:50 PM

The actual mechanism with those pogo pins is a hit/miss. That's likely why VKB went with another revision to fix those intermittent connection issues. I've had it for a while with the VKB base, changed few of those contact plates sent from VKB, but it was all fine until the pins made some gouges and then the issues started to appear.

The way I see it you have 2 fixes.
1. Less intrusive.
Just add some solder on the pads to increase the contact area. It should help
2. Taking sledgehammer approach.
Directly solder the wires coming from the adapter to the wires coming from the grip. Upside, no frigging way you'll lose contact. Downside, changing grips is "problematic" to put it mildly unless you go nuts and add additional connectors to be able to separate them.

This is what I did, option 2. Wouldn't recommend it outright, but as I only have one grip (MGCU), this was a result of some thinking. Ever since I've done that, 0 connection issues have happened.

Tomsk•1/26/25, 4:52 PM

Yeah I did think the VKB pins look like a crappy design. I'll definitely consider attacking it with a soldering iron. I also only have one grip and soldering it to the black box unit wouldn't be a terrible loss from my POV.

Tomsk•1/26/25, 4:56 PM

I'm guessing it's fairly obvious which wires to connect?

Vakarian•1/26/25, 4:57 PM

Walmis drew the pinout diagram somewhere in the discord, but it's easy to follow it up if you take a bit of care when removing the small PCBs where the pads and pogo pins are. Those are marked with + / - / data lines, so just connect them and you're fine

Vakarian•1/26/25, 4:58 PM

IIRC, Red is +, Black is - and the Yellow one is the data

smitty•1/26/25, 10:47 PM

you will need USB-A to USB-B cables

smitty•1/26/25, 10:48 PM

and however you want to hook up the 24v can be whatever connector you like

smitty•1/26/25, 10:48 PM

xt60 recommended

Ssmitty you will need USB-A to USB-B cables

GettinBetter•1/26/25, 10:49 PM

Are all the other connections DIY? Any idea what the PCB sockets are?

smitty•1/26/25, 10:50 PM

they are screw-down-on-the-wire type

Blackrat•1/27/25, 12:09 PM

Help, just building the MFG pedals Rhino conversion and I cannot get the motor to work, I hope its something simple, I have checked the wiring, tried a different PSU. The software shows power to the board. Any ideas ?

Blackrat•1/27/25, 12:10 PM

Blackrat•1/27/25, 12:11 PM

Its a devilsd job securing to the rig so I really don't want to have to lift it all out lol

walmis•1/27/25, 12:13 PM

Probably a would have been a good idea to test it before installing

What's the LED blinking pattern on the motor?

walmis•1/27/25, 12:14 PM

maybe disabled the wrong axis?

Blackrat•1/27/25, 12:14 PM

I will need to pull it all ou then I guess

Blackrat•1/27/25, 12:16 PM

OKay my motor is a Y axis then not an X axis

Blackrat•1/27/25, 12:16 PM

Looks like it was taht simple many thanks @walmis

Blackrat•1/27/25, 12:18 PM

Teach me to follow the instructions to the letter

walmis•1/27/25, 12:35 PM

@Blackrat you can tick the Swap axis checkbox for it work on X axis and disable Y axis (as required by telemFFB)

Blackrat•1/27/25, 12:36 PM

@walmis Thankyou will try that

Blackrat•1/27/25, 12:37 PM

Perfect, not sure if it matters but keeps in line with others

Nozzledude•1/27/25, 3:14 PM

What causes “under voltage error”?

walmis•1/27/25, 3:23 PM

When the motor detects voltage less than 8V from the main power supply

Rocco Thamanoidis•1/27/25, 9:27 PM

Ehm, did u just try my solution from above?

Rocco Thamanoidis•1/27/25, 9:28 PM

And the undervoltage comes from pushing the emergency button. When it happens next, first what the log before pressing the button to verify.

Rocco Thamanoidis•1/27/25, 9:29 PM

Then try my workaround and shut off MSFS Support in TelemFFB SystemSettings.

Wwalmis When the motor detects voltage less than 8V from the main power supply

Nozzledude•1/27/25, 11:38 PM

What is root cause of that? bad power supply? I just opened it from the box.

Havebug•1/28/25, 9:04 AM

I had a similar issue and found out that the power supply, when motors are under heavy load and demand more current, sometimes can't handle the current spikes and lower the output.
I fixed this by adding a charge tank (basically a capacitor with low ESR) next to each motor.

Havebug•1/28/25, 9:07 AM

I guess you can have a similar workaround by placing a capacitor in parallel at the connector right before it attaches to the Rhino

walmis•1/28/25, 9:27 AM

This shouldn't happen with the stock Rhino. I'll release a new firmware update soon with more diagnostic output and stability improvements, should help debug such issues.

jskibo•1/28/25, 4:18 PM

On latest firmware. Yesterday everything fine, today the configuation software picks up all button and hat presses, but windows and MSFS doesn't register any button presses. TM F/A-18 grip, first time i had any issues

walmis•1/28/25, 4:27 PM

If the configurator shows button presses, try loading the default Rhino configuration or checking the button mapping tab, maybe the button mapping is corrupted somehow.

Tomsk•1/29/25, 2:34 PM

Just an update on this. I took both the Rhino VKB adapter and my VKB made stick extension apart, and directly soldered the two sets of wires together. Works perfectly now. It just means I have a combined stick extension + Rhino adapter, which works fine for me. Thanks for the suggestion

GTOfire•1/30/25, 11:51 AM

Sanity check: I'm finding it super convenient when I hop in and out of my rig to just pop that red emergency stop so the stick tilts forward and out of the way (as opposed to having to step over it while upright).
Should I avoid pressing the emergency stop if not needed, or is this a perfectly safe habit to form that won't cause longevity problems?
