Страница 1: ... it is highly recommended that the installer determine an optimal mounting location by using a cell phone display to assess the signal strength The standard antenna supplied with the Gateway has a magnetic base and a 6 2m cable that allows mounting on top of a tank or structure for optimal signal strength while mounting the Gateway in a more sheltered or accessible area The optional SMA mounted an...

Страница 4: ...Gateway is not supplying sensor power the red wire is either cut off or insulated with tape inside the sensor The black wire from the red black pair is still connected to provide a signal common for the RS485 link so it is connected to Common at Terminal 4 mA Output The shield is shown grounded at the power supply and not connected in the sensor As AC powered sensors have both Terminals 3 and 6 ea...
