How To Have More Than One DM1?

Hi Guys,

If I send a DM1 CAN message (PGN 65226) I get all good in CANAnalyzer.

How do I Send another at the same time and have it also appear? I have tried switching the two DM1 Outputs off alternatively but nothing changes in the analyser detection part, only the data stream changes.

What's the correct way to send out multiple DM1's at the same time????
