Dear Sir,
Thank you very much for using the Developer Exchange.
At this time it is not possible to use the NI-1127 over RDA. What you can do though is to run the VI remotely using VI server. This way you can develop your application using NI-switch in the remote machine and then control the execution remotely using VI server or via TCP/IP if you are using other programming language than LabVIEW.
Best Regards.
