Kverneland focus 2

[Steevo]

Just Googling for how to link Trimble 750 and KV Focus box and found this. Remember reading it before but had forgotten.

Think i’ll skip it for now and make do with simulated speed.

I will make you a cable if you would like one. It’s not very difficult.

Wow, thank you! That would be amazing.

Trimble to KV focus 2? How long does it need to be?

Trimble to KV focus 2? How long does it need to be?

Yes please. Trimble to Focus 2.

I think 1m would probably be enough, but wonder whether it’s better to play on the safe side and go a little longer. 1.25m or 1.5m perhaps?

To get it to work with a Trimble GPS (and probably other sources) you need a 10k resistor between pin 1 and the middle pin to pull the voltage high so as the Vicon Focus 2 box can 'see' the pulses.

Good old thread this one. Just going full circle on this - and possibly to help others in similar situation - it appears that Trimble don’t (or at least didn’t with the 750) have the option/software setting to “enable pull-up” on their simulated radar output.

I was just scanning over a manual for an old Topcon display (another thread don’t ask) and happened to see that they actually do offer the option of a software “pull-up” on their simulated radar output:

Anyway anorak moment over Nice to have you “back” and posting again @sleepy

Nice to have you “back” and posting again @sleepy

Can’t like this enough!!

Hi all, I need to fit my sprayer onto a different tractor that doesn't have a wheel sensor on, but it does have the amphenol socket with a speed output. The sprayer box had a 2 pin plug, one +12v one 0v and I have an amphenol plug to use. I was just after a bit of advice on which pins to use on the amphenol plug, the speed out put one obviously, but does that go to the +12v on the sprayer box or the 0v, and which other pin do you use on the amphenol plug.

Cheers Joe.

Pin 3 is wheel speed if it’s wired to standards. The Amphenol connector will have the pubs labelled. Centre pin is ground.

Just connect pin 3 on the tractor to +ve input on the sprayer box. You probably won’t need the ground cable (it should all share a common ground) but won’t do any harm to connect it anyway.

Thanks @sleepy although its pin 2 not 3 on the amphenol plug. When you say connect pin 2 to the +ve input on the sprayer do you mean the pin that is normally at 0v when stationary with the box turned on. The other pin is at a constant 12v i think. Maybe i just need the one wire from the amphenol pin 2 and leave the +12v from the sprayer disconnected?

Normally to the ‘constant’ 12v one. The tractor will pull it low which the sprayer will recognise as a pulse. If you put the sprayer box in it’s diagnostic mode and touch the +12v one to ground you should see it register the pulse

Your not going to blow anything by trying it out

Ok thanks. Have got the cable made up so will have a play round and see.

Basically the sprayer box has a little resistor between the ‘constant 12v pin’ as you called it and +12v known as a pull up resistor.

This keeps the input high (ie. at somewhere around 12v).
When a path with less resistance is available (ie. if you connect it to ground / battery -ve) the resistor effectively stops passing any current and the pin goes low (ie. something near 0v).

If there wasn’t a resistor the input would ‘float’ and could be triggered unintentionally by inductive currents etc.

The reason for this thread was that the KV box I had for whatever reason didn’t seem to have a pull up resistor in it and it didn’t like talking to my Trimble GPS which only puts out about 5v which wasn’t enough for the kv box to register.

So I put a resistor between +12v and the input on the kv box, so it ‘floated’ at +12v, and the Trimble box then pulled it to 0v which it could recognise.

Hope that makes sense.

Ok thanks @sleepy yes that makes sense.

What is the easiest way to get speed signal with FOCUS 2 control box?

 

[SinisaB]

Has anyone tried this with gfx750? I suppose it goes on the displays 5 pin connector pins 2 and 4.

 

[lolojunk]

Wahoo I solved it

Which donut at Kverneland thought it was a good idea not to put a pull up resistor on the radar input

Hello, i have the same équipement, i understand the plug on the Focus2 but how did you do on the trimble EZG250? thank you and excuse me for my english... i'm à frenchy frog ;-)

buongiorno, vorrei sapere qualche informazione, ho un kverneland focus 2, avrei bisogno di attaccarci uno strumento isobus ma il cavo adattatore è troppo costoso e non disponibile, vorrei sapere se è possibile averlo il manuale con il pin fuori fuoco per permettermi di realizzare in autonomia l'adattatore isobus. Inoltre vorrei sapere se è possibile collegargli un sensore per rilevare la velocità del trattore attraverso la ruota?
