Problem with 4 flexray Cards

[MeuhMeuh9360]

Hye 

I am developing a test bench to make some validation on prototypes. I have to drive 4 flexray cards in same time. The problem is the communication doesn't work on the 4th. I changed the card, the slot PCI and the computer but the problem is still here.

Someone knows if we have limits about the number of flexray Card or another idea to help me to fix my problem?

thks

can you please describe in more details,  what software are you using and which verison of NI XNET. Are the boards detected in MAX? What errors do you see?

Yes of course

i am using NI XNET 1.8, ECU Measurement and calibration 2.3 with PCI Flexray 8517. All the card are detected by NI MAX, I can Blink the led on the 4th cards the steup is good with the 3rd first card. When i use the 4th, I don't have any error message, It's like that I have simulated the card but nothing happen on the bus.
