Dewesoft address claim

I am trying to set my Dewe43 as a specific address on a CAN network. I think I need to send the claim message as soon as the bus is powered up, is there a way to do this?

Can anyone provide an example on how to send an address claim message?

Dear Brian,


Is this for J1939? For receiving J1939 messages it is possible to set a source filter, like on the attached image. Is this what you meant?


Best regards,

Primoz

It is J1939. However, I am trying to transmit a set of messages as coming from a specific node. I need other controllers on the bus to see my Dewe43 as "D5"

J1939 in this way can only be send as a standard CAN message. There you would have to define the Arb. ID and complete message and you would have to know exactly which bits represent the address. It is a bit of work but possible if you know how exactly the message should be constructed. With math, you could also make a formula to increase the address value if the one sent is already in use.

I figured it out. If I uncheck the J1939 checkbox, I am able to enter the full address. Unfortunately to uncheck it, I had to delete all the channels that were set up and redo them. But it is working now.
