multiplexor issue, messages not processed

george zalesski 1 month ago in IQANdesign • updated by Gustav Widén (System support) 4 weeks ago • 1

HI,

I'm using a J1939 PROP _B massage that is multiplexed,  The index in in byte 3 (mask 0XFF0000) . If I remove the page protocol, the massage is processed  and I get the data. I can manually process the Index and get the data, but when I use the index and page mask the massage is not processed.  Has anyone see this?  index is 8 bits.  I have 16 index's values starting from 0 to 16 defined.

How did you define the page value on your JFIN?

To enter it so it ends up matching at the right place, you need to keep trailing zeroes.

 For example, if the message on the bus has value 1 in byte 3, you enter page mask as you've done 0xFF0000, and page value as 0x1000
