Safety

CAUTION

Strong magnetic field

The DS Digitized Per Pin (DPP) Receiver Distributor (Rx Dist) has no ferrous material and will not be attracted to the magnet, but the eddy currents can cause resistance when you pull the DS DPP Rx Dist away from the magnet.

When removing and replacing the DS DPP Rx Dist, keep the receiver as far away from the magnet as possible while moving it.

Procedure

Align the two keyhole shaped screw holes and two slotted screw holes on the DS DPP Rx Dist over the screws on the side electronics plate.
Make sure the blank side of the DS DPP Rx Dist module points to the right.

Figure 1. (For AR magnets) DS DPP Rx Dist module installation

Figure 2. (For UA magnets) DS DPP Rx Dist module installation
Lower the DS DPP Rx Dist until the top two screws are in the smaller portion of the keyhole shaped holes, and the bottom two screws are in the slots.
Tighten all four screws to secure the DS DPP Rx Dist.

Notice

Component damage risk

Applying too much force when pins are not properly aligned to the corresponding socket will bend the pins and can break the connector or cable.

J5, J6, and J7 of the DS DPP Rx Dist are Twin BNC plugs for a local oscillator cable. Align pins and keys properly before connecting them.

Connect all cables that you previously removed to the DS DPP Rx Dist.
