Massey NMEA to RDS Artemis

[Longpod]

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 and forward speed. This I understand will be done via NMEA. There is a NMEA socket in the fuse box labelled X343. It is a RS232 (7 pin socket).

So far I have found out the following:

The RDS RS232 socket only needs two wire to go to it, ground to pin 1 and receive to pin 4 (this is what the Trimble currently uses)

The Massey RS232 socket has however 3 labelled wires connected to it:

X343 2 / X282 11 to pin 2
X343 3 / X282 10 to pin 3
X343 5 / X282 7 to pin 5

Does anyone know which of these there wires is Ground and which is Receive?

Your help is very much appreciated.

RS 232 is usually pins 2,3 and 5 with 5 being signal ground.... however. RDS use I think 1,4,5? (Their end) So I’d call RDS to get the correct cable made

Thanks Robt, I called RDS and they told me: ground 1, Transmit 3, Receive 4

So that makes me guess:
RDS pin 1 to Massey pin 5 (hopefully ground)
RDS pin 4 to Massey pin 2 (hopefully receive)

What could possibly go wrong..........

Just made up a cross over cable, and so far so good, we have forward speed now showing on the RDS box. Will give it a go tomorrow with the fert spreader on variable rate application. Fingers crossed.

Good luck, hope it works out. I gave up in the end trying to make a cable for my case ih pro 700 screen to rds Artemis box, just couldn’t figure it out. I’ll be watching to see if it works for you.

RS232 is not really that hard. Even if you mix up transmit and receive, you’re not going to nuke anything, just swap them over and try again.

Ensure you have the correct baud rate set, parity and word size is generally 8N1between the devices. Check the correct NMEA sentences are also set for speed, position.

 

[Longpod]

I can confirm that the cross over cable was a success. I was able to get GPS forward speed a position. Below is a few notes to help anyone else in my position ( I knew nothing about NMEA before this)

The above photo resembles the RS-232 female plug in the fuse box labelled X343. It seems to be quite a standard layout unlike the RDS side.

Settings on the NMEA page on the FieldStar 5 screen are as follows:

Transmission speed: 9600 (make sure this matches the baud rate on the RDS box)

Parity: No Parity

Data format: GGA - transfer speed 5.0, VTG - transfer speed 5.0

Best fish my cable back out of the bin and have another crack at it!!

Did you just buy the connectors and make a crossover cable then

Did you just buy the connectors and make a crossover cable then

I’ve made up two cables. The first I bought a serial cable, cut it in half and rejoined the wires in the correct order.

The second cable, I purchased a serial cable, cut the plug off one end and bought a new RS-232 plug with screw terminals for easy wiring from eBay. This second cable was much neater as there was no join.

Have you any eBay links to the screw versions as I only see solder ones

So I got the rs 232 connectors to day and made a crossover cable but not getting speed read out on a krm calibrator Zurf any ideas

 

[Longpod]

As you now know what the rs232 pins do on the Massey side, it’s just the KRM side. Give them a ring, they should be able to tell you. Failing that, it’s trial and error. If your struggling, carefully open the KRM box and as long as the rs232 socket is not soldered to a circuit board, you might be able to see what pins are being used ?

 

[Longpod]

Have you turned the NMEA on and put in the settings on the Massey side?

We have a Calibrator Iqon. There is a round plug in it for speed signal. And we feed the speed there. It is in pulses (Hz) and one can use wheel sensor, tractor provided speed pulses, speed radar or simulated radar speed from gps receiver.
Our Iqon does not understand NMEA position & velocity message... I think zurf might be somewhat similar.
Please read the Bogballe manual...

The Serial cable in the Iqon is used for rate and "section" control with Trimble CFX-750 (variable rate unlock needed for prescriptions). I say "section" as our spreader does not have individual adjustments for the two plates.
Headland controll & rate control work fine. There is small "Section Master" box made by Dataväxt between CFX-750 & Calibrator Iqon.
Speed pulses come straight from CFX to Iqon. No ground wire was needed here as they share the same ground anyways...

No scale on the spreader. Has been good enough with the settings we can find from the Bogballe App. And after the first bag is out we can fine-tune if needed.

Took a quick look at Atremis-Lite & RDS Artemis manuals also. Those instruments seem to accept only speed in pulses...
(Speed Sense Factor 0,00611 m/Impulse = default for RDS Artemis...)

And please educate me if I'm all wrong!
