PCI-CAN/XS2 Single wire configuration (cont)

[Rich_G]

I set CAN1 as a bus monitor looking for data from the Module,

I connected CAN0 to 9pinSubD pins 3,7,9

I connected Can1 to the same

I have +12V to pins 3-, 9+, to power the modul and SW CAN

I am seeing no activity

The function is working but I have one more question

I am looking for a response  65d xx xx xx xx xx xx xx xx

Will the Rx set to CAN0 pick this up or do I need to somehow configure the Rx to look for 0x65d ?

ThankYou

[Rich_G]

I am still trying to trap a response from the module.

I hooked up an o-scope to monitor traffic.

My Wakeup should be at a higher amplitude to wakeup the bus.

The signal is at the same amplitude as all other communication.

What did I miss on the setup?

[Rich_G]

With my other CAN communication tools the Wakeup is above 11V with normal communication at 5V nominal

With the NI card all transmitions (including the WakeUp) is below 4.5V.

I am using the same module and the same power source and the same cableing etc...

The main difference is the tool and the software.

I need to get a handle on the wakeup settings.

I have tried many things, but no luck yet.

Hey Rich,

You would need to configure you Can device to what information you are looking at. I'm not sure if you had a chance to look at this start-up tutorial, but it explains the process of getting up and started with NI-Can.

Good luck!

can you please check if this vi's works for you

[Rich_G]

Hello Rgomez.

The last post was 2007...

I have had this working for many years...

But thank You for responding.

I do appriciate feedback.

[rgomez7408]

Can you share your code? I would like to use XNET and replace the CAN vi's

[Rich_G]

I am sorry, the library is licensed to Aeroflex. You can look them up on the web. But it is developed for the test systems and uses a unique language called Marconi Test Language.
