i installed a FMB140 (with All-CAN config) with the CAN Lines to a DAF CF truck. I have set the CAN Program Number to 11465, saved config to device, load config to device and under "CAN Adapter -> Program number" i can see the 11465. Everything is working as expected.

Now i want to install it to a Fendt 828. Therefore i want to set the Program Number to 13148 or 12736 (for a Fendt 826). But if i do the above procedure, i always get the old Program Number. So the adapter is not accepting the new number. I also tried the Autoscan function, but it only shows one number, that seem to be incompatible.
I connected CAN1 to ISO Bus. I can also read the RPM of the engine. So communication is OK.

Does someone know, whats wrong?

In the Fendt tractor there is a ISO, K- and V- Bus. The FMB140 got 2 CAN interfaces. Can i connect CAN2 to K or V Bus to get more information?

I also wrote an email a week ago to, but they didn't reply.
Thanks in advance.

The FMB140 has FW 03.27.07 Rev:00 / Configuration

I suppose your internal CAN adapter needs a SW update to be able to handle the newer Fendt programs

Please read the instructions on how to update  SW via Fota Web

After update  please try to set up the necessary programs again.

Ok, i contacted via Web form.

How can i differentiate between ALL-CAN and LVCAN version of the FMB140 (except from the package product number)?

You can send the command SMS/GPRS 


If you find in the answer

SWVer: 73 Opt: A  - this is LVCAN mode

SWVer: 73 Opt: 3F- this is  ALLCAN mode
