Install Dust Monitor at End-X for Vent
Dave B., Filiberto C., Jeff B. 

   The in cleanroom dust monitor(VEA 2) has been installed at End-X to support the up coming vent. Dave did the updates to dust monitor software to remove the unused monitors from the LVEA and add monitors for the end stations. 

   The End-X monitors were (1) incorrectly connected to the RS485 serial network, and (2) A wire loop in an unused but connected RS232 box was shorted. Filiberto and I reconnected the dust monitors correctly for the RS485 serial network. While trouble shooting network intermittent lockups, we found and isolated the shorted RS232 wiring. 

   Both end stations dust monitors are up and running. The AlarmHandler and "check_dust_monitors-are-working" scripts are being edited to reflect the current operating environment.
