Hi Shimon,
1) It sounds like you are using a PXI-8176 running Windows as a host PC, and you are connecting to a remote PXI-8176, is this correct? You should not be seeing any devices in your host PC if you do not have anything connected to it. The PXI-6071E and 6527 on the remote system should not turn up on your local system, so your like your MAX configuration looks correct.
2 & 3) You might possibly need to redownload the Excalibur drivers for LabVIEW RT to your systems so that it can be recognized.
