Tractor gps signal out cable

[lostdog]

Does anyone know if it is possible to get a GPS signal out of a new mf 7718s?

I want to use the tractors GPS to supply the signal to our mueller controlled knight sprayer. The sprayer came with a little receiver which connects to the back of the mueller terminal via a serial port but I would rather use the more accurate signal from the tractor. Also I wouldn't need to worry about moving the receiver from tractor to tractor or whether there would be problems having all that gear on one tractor.

Anyone any ideas? I have asked the dealer and am waiting for them to come back to me but I thought I'd try here as well.

Thanks

Hi, what GPS system is on MF? the factory fit Novatel?

 

[lostdog]

Oh sorry meant to say. Factory fit trimble

 

[Robt]

Then there should be an NMEA port to export GPS to a n other screen

 

[lostdog]

OK, that must be hidden somewhere. What would it look like or is it different on everything as usual?

There will be a RS232 cable usually hidden down the right hand side either by the fuses or sometimes dropped further down. If you take the cover off by where 6/7 spools are you should be able to locate it.

I will have a look in the morning. Thanks very much everyone, for now anyway.

Are you going to be using the section control in the 77 for auto shutoff in the knight sprayer

 

[lostdog]

No, tractor will just do auto guide and the knight screen can take care of the SC. I would need to get the tractor unlocked to do SC so thought we'd just leave it as is.

has anyone a pin out diagram for this rs 232 cable

 

[lostdog]

If I remember correctly, as I didn't pay that much attention at the time, there are only 4 wires going into it from the tractor. The DB9 plug looks like it comes apart easily enough.

I hope this helps:

Massey NMEA to RDS Artemis

Massey NMEA to RDS Artemis

For the last 10 years I have successfully had a RDS Artemis box linked to a Trimble EZ250 to provide GPS position and forward speed for a Sulky fertiliser spreader. I now have a new Massey with Fieldstar 5 and autosteer. I want to connect my RDS Artemis box to the Massey for the GPS position...

Not sure what the connector looks mike but the standard RS232 connector is below.

This pin out for a massey? Cheers

I always find the tx and rx pins confusing, which one follows the computer port pin numbers and which one has them swapped. Better to check with a multimeter first, easy to find which pin transmits data.

Don't know about Massey and are they all the same but most likely you anyway only need ground, rx and tx.

Did you get this to work from the rs 232 cable
