Can I plug one more MXI link card in PXI-1033 in order to work with it

[Current_93]

Dear colleagues,

Tell me please can I plug one more MXI link card in PXI-1033 chassis in order to work with it.

In other words I don't use integrated MXI controller and want to work with NI PXI-8366 MXI-Express and PXI-1033.

Thank you.

The short answer to your question is no. The issue that needs to be considered is the type of slots we have access to on the PXI-1033. To use a PXI MXI card for control purposes in a PXI system, we need to use the card in a system controller slot (designated by a triangle around the slot number on the chassis). With the 1033 though, we do not have access to control slots. Due to the embedded MXI controller connection, we only have access to a timing/triggering and peripheral slots.

Is there a particular reason that you don't want to use the embedded MXI connection on the 1033, or do you simply want to prevent from having to change the connection to a different computer?  The only MXI cards that would function in the available slots on the PXI 1033 would be something along the lines of the 8367 and 8367, which are used for daisy-chaining to a separate chassis.

Dear Timothy

Please advice me simply I'm confused about stability MXI copper link - so many my colleagues tell me that it very no stable and often occurs communication lost with copper link.

So many says me that only fiber optic MXI link is stable.

Please help me previously I want to use  copper  MXI in 24/7 mode and I'm afraid  that occurs an unpredictable  hangs up.

There are no real stability issues with the MXI copper connections that I am aware of. The cables are shielded as most copper cables are to prevent this type of instability. The MXI-Express connection (in the 1033) does have error checking built it, and will retransmit data if an error is detected. I'm unsure as to what considerations you are worried about in this regard, as there shouldn't really be any stability or noise concerns with the MXI copper connections. Anything that would affect the stability of a copper connection in this case (i.e. an unnaturally large noise field or physical considerations) could, and likely would cause the same type of instability in a fiber-optic cable as well. I wouldn't hesitate to use the MXI copper connections in a 24/7 application without a very specific reason to consider otherwise.

I also noticed that you had posted a very similar question on another related thread. In the future, it would be best to keep these questions to one thread so as to keep the responses as focused as possible. Thanks.
