What is needed to allow the EZ Guide 500 to perform auto boom switching (swath control) with the Hardi 5500 controller on a Hardi Commander 4400 sprayer?  I was told that a direct connection from the EZ 500 to the Hardi 5500 was possible without the EZ Boom being needed, but am having a difficult time assessing what is really needed to make this work.

Thanks,

Thanks!  I knew it would take someone from across the pond to get good information.  Hardi does well here, but only in some smaller areas and I'm not in one of them.  Most of my area is self propelled or low cost pull types.  Hardi makes great products but most don't see the value of the extra features and the durability and performance of the unit.  We have never had one of the larger, better dealers take on this line so my biggest problem is the distance to my dealer to get good resale on my sprayer and service if I have an issue.

I think the Hardi 5500 is the "JobCom" from what I've read.  I was hoping that only the cable was necessary ($45) since I didn't want to do variable rate, but swath control only.  It looks like the unlock for variable rate is $750.  This looks to be a fairly quick payback if it's $795 to get it done.  Based on several models  I conservatively figure to save around $4000 per year in chemicals and liquid fertilizer.

Thanks again for the help,

Here is a link that you need to check out http://www.hardi.com.au/en-au/TechnicalInfo/~/media/extranet/australia/Website/Support/manuals%20operators/controllers/Trimble-HC5500-Installation_0909.ashx  Click on the link and it will download, may take a little time, just wait for it.

It is a guide for connecting Trimble Ez-guide 500 auto section to Hadrdi 5500 controller.
On page 13 it says "Note: the Hardi 5500 controller must have firmware version 3.16 or higher installed and have a Jobcom control box connected for it to work correctly with the Ez-guide 500 lightbar."

Some sprayers have the Jobcoms some don't. Depends on model.

This guide tells you everything you need to do to have auto-section control.

My dealer quoted me $1,495.00 for the jobcom, $30.00 for a cable & $750.00 for the unlock code.
$2,275.00 total to do it,  If you don't already have the Jobcom.

Thanks, that is a very helpful link.  I didn't find that doing a search on the Hardi site.  Reading the material did lead to another question.  Can the job com be internal in the HC 5500 controller?  My HC5500 is version 4.0.  This was unclear to me in reading the tech bulletin.  If the job com control box must exist as a separate box, then I know that I don't have one.  I wish the tech bulletin had a pic of the job com other than the close up connections and I wish the layout for all connections were in the same diagram with the EZ 500 -- i.e. which ports would be used to connect to job com if the com1 port was connected to the EZ 500.

One more thought -- is the job com located with the cab controls or on the sprayer itself?

As I understand it (so take it for what it's worth) the jobcom is a sperate box mounted on the sprayer that plugs into the existing wireing harness at that point and no extra wires come into the cab. Sprayers that have the steerable axels have one , I'm not sure what other features require one. I just know I don't have one.
I'm in the middle of researching this for my sprayer also, so I haven't actually done it yet. Hope I'm not giving you inacurrate information but this is my understanding of how it works.

Thanks again, as I read bits and pieces, I am coming to the same conclusion.  I plan to call Hardi tech support on Monday.  The number I have for tech support is 866-770-7063.  I'll let you know what I find out.

Thanks for the update, sounds like a reasonable thing to do cost wise and I like not haveing another box in the cab.

Wow that's a lot cheaper than I was quoted in Australia. (AU$3750 to upgrade Navigator with Jobcom Box) I gave up in the idea because of the price.

Is the upgrade and installation of the jobcom box something a dumb farmer like me could do, or does it take a lot of tech knowledge? Are there detailed instructions available on how to do it?

Wondering if I could buy the jobcom from some nice, helpful dealler in the US??  ;-)
