To start, I'd just need remote access and admin privileges on the PC HDICENMR4 to start by looking at it remotely and at least seeing if I could get communication going between the PC and lock-in amplifier.</div>

<div class="PlainText">Hi Tyler,<br>
<br>
I wanted to give you an update on the Lock-In Amplifier. I haven't had<br>
much luck or made any progress with the computer center this week. Wei<br>
recently switched the racks around and changed the connections around in<br>
order to run NMR scans with HDICENMR2 and the old NMR system.<br>
<br>
HDICENMR1 and HDICENMR2 are both plugged into a switch, which is then<br>
connected to the ethernet port in the lab.<br>
<br>
HDICENMR4 use to be connected to the switch and connected to the lock-in<br>
amplifier with a USB cable. Now it is connected to it's own network port<br>
and the USB cable has been removed.<br>
<br>
The Zurich Lock-In Amplifier is no longer connected to any PC via USB<br>
cable. The lock-in is now just connected to the network via an ethernet<br>
cable going to it's own wall port.<br>
<br>
HDICENMR2 will be in almost constant use, so Wei suggested we now try a<br>
simpler setup with just one PC and the lock-in. We'd like to see if we<br>
can get just HDICENMR4 to control the Lock-In amplifier over the network.<br>
<br>
Would you be able to give us a hand with this new plan? If you have any<br>
thoughts of suggestions, let us know.<br>
<br>
Thanks,<br>
Tom<br>
