Adeunis Field Tester - NO downlink power display

My Adeunis FTD is for AS-923. I set up in the Application Server.

The tester’s Uplink is confirmed by the server; however, the tester cannot show the downlink power, the server’s datadown is not confirmed.

Please help.

When I “ticked” the “Device is disabled” under the “Applications”, The Field Tester can show the downlink power and SNR.

However, I do not know which gateway communicates with the Field Tester.
