Power / ground

Does the ground go to the gnd port next to ant? Which port of 24vdc? I’m assuming you gave two ports and it doesn’t matter. Or is one ground, and power?

Power goes to upper right terminals of the receiver, see photo below.

The gnd port next to ant is for ANTENNA GOUND SHIELD ONLY.
Please do NOT use it for power.

Thank you.
