Hello,
I need to interface our data acquisition software with a NI PXI-7334 controller. I see that I can use the NI-Motion library under Windows to interface with the controller. I have two questions (I couldn't find the answers by searching the NI web site):
1) Since we also support Linux, is there an alternative for this?
2) Is there any documentation for direct serial port control (the application would send commands directly to the controller via the serial port and not use the NI-Motion library)?
Thanks,
Greg

Jochen,
If I understand our customer correctly, they are planning on using the PXI bus - it looks like a serial port module is an option for that configuration.
Thanks for the quick reply - that's what I was trying to find.
Sincerely,
Greg

Greg,
if you use a PXI system with embedded controller, a serial port as well as an ethernet port are standard, so you could use the PXI-system as a standalone controller that accepts commands from external devices through these interfaces. Other interfaces like CAN, Profibus or other busses are available, too. In this scenario you would have to implement a command interpreter that translates from the external commands to NI-Motion functions.
Please let me know, if you need more detailed information. In this case, please provide a better overview about the system architecture.
Thanks,
Jochen
