Abstract Information:

Prior to observatory automation, all the lights at the summit were controlled using local light switches. Lights that were inadvertently left on during the day that impact observing can previously could be turned off by the night staff. Likewise, the night staff could turn on lights as needed for troubleshooting. Remote observing will make this impossible. The use of WebRelays provided a means for remotely turning on or off critical lights as needed. WebRelays are an Ethernet based relay that can be controlled either using network commands or by supplying voltage to an optically isolated input on the WebRelay.
