Hi Amrit,

Tom O'Connell is a grad student with the HDice group. Andrew Seitz is from Computer Center.

The issue was that the new Zurich lock-in amplifier could not be read over the network, so HDice asked for our help.

Peter got the lock-in amplifier assigned a Hall B subnet IP address (129.57.86.121) but the PC HDice was using was not on the Hall B subnet. After getting the PC on the Hall B subnet, neither the PC nor the lock-in amplifier were able to be reached over the network because the network ports the PC and lock-in amplifier were connected to did not allow the Hall B subnet. Computer Center was able to resolve that on their end and now the PC and lock-in amplifier are accessible on the network.

-Tyler

tyler for my benefit could you summarize this issue in about 5 sentences!
who is tom and who andrew?

Hi Tom,

I can also get to the lock-in amplifier over the network. I successfully connected to it from both HDICENMR4 and one of DSG's Hall B subnet PCs.

It seems that the network issues have been resolved.

Hey Tyler,

Andrew corrected the problem with the lock-in amplifier.  I can now access
it on HDICENMR4 through the network.  The LabOne controls are working just
as they would using the USB connection.  When you have chance, could you
check if you can do the same?

Best Regards,
Tom
