Pulsar Relay

Pulsar dome user guide is devoid any detail concerning the operation of the dome controllers relay installed in my control box.
There are two settings to set the polarity as either NC or NO and the e general census is NO. Another factor to consider the output from the relay switch could be either power in or power out but I have no idea which one applies and this could determine the setting.
Lunatico cloud sensor is wired from the positions on a post now to Lunatic’s Solo having upgraded from using their software installed on my dome-based lap top.
Currently if I set auto open and polarity as NO the dome the shutter opens. Switch polarity NC in day light and the shutter closes trying later at night brings the same result. Maybe going to the control box under setting use test relay with NC a longish black line appears. Switch to NO nothing is displayed.
My plan once I have cleared the back of the garage is to run an ethernet cable from the house to the socket in SOLO. Hopefully this should enable the full suite of software and adjust where necessary.
Wait and see
