Subject: PEM monitor computer is ready to run - needs license 

The Newport temperature, pressure, humidity remote sensor unit (zED-BTH) in the PSL lab was sitting on a recessed shelf of the work bench. This isn't a great location for accurately sensing and logging the lab temperature. I have now mounted it on the center of the western wall of the lab (pictured) 1.524 m from the ground. This location has free air flow.

Indicator LED also wasn't blinking. I checked the batteries and they were down to about 0.200 V for each of the AAs. I've replaced them as of today.  

It seems like these units have an email alert function: http://www.newportus.com/ppt/ZSERIES.html . Maybe we should set one up for battery replacement alarms.

We've set up the PEM monitor computer to broadcast the temperature channels to EPICS.

  • Computer is a Windows machine at 10.0.1.35
  • Has OPC server installed to communicate with the Newport zCDR wireless unit
  • OPC server still needs a license. Currently terminates after 2 hours
  • OpcIocShell runs to create an EPICS IOC that interfaces with the OPC server and broadcasts the channels via EPICS.

We'll find a permanent home for the machine tomorrow.
