Installing the Replacement Stationary Electronics Box
1.Insert the second (larger) motor connection into the port underneath “P4 ELEVATION” on the replacement stationary electronics box.
2.Insert the first (smaller) motor connection into the port underneath “P3 AZIMUTH” on the replacement stationary electronics box.
3.Align the two holes in the electronics box and the frame. Insert a screw through each hole, and tighten with a 1/4” Allen wrench.
4.Connect the coaxial cable running from the left side of the LNB to the port underneath “LNBF.” Make sure the cable still runs behind the LNB. Tighten until fingertight, and then tighten a quarter turn with a 7/16” wrench. Do not overtighten!
5.Connect the other coaxial cable to the port underneath “RECEIVER.” Tighten until fingertight, and then tighten a quarter turn with a 7/16” wrench. Do not overtighten!
6.Plug in the power supply connector, and tighten the two screws on the side of the connector with a small flat screwdriver.
7.See “Routing the Cables in Cable Harnesses” on the next page to finish installing the electronics box.
