SV-ADAHRS-200/201 Installation and Configuration

5-6 SkyView System Installation Guide - Revision R

 Engine heat and exhaust

 Aircraft interior (back side of probe)

 Heated air from the cabin exiting from an open window or cabin air exhaust port

The installation area should have space for a nut and wires on the back side of the probe. It is

acceptable to extend or reduce the wire length if necessary. Reduce the wire length by cutting

out the desired length from the middle of the wires and splicing together the remaining ends.

If there is a backup ADAHRS in the SkyView system, it is acceptable to install a backup OAT

probe a few inches away from the primary probe. Consider running primary and backup OAT

probe wiring together. Tape probe wire pairs together to avoid confusion later.

Installation

The following tools and materials are required for SV-OAT-340 installation:

 SV-OAT-340

 SV-ADAHRS-200/201

 Drill with 3/8” drill bit

 9/16” wrench

Do not insert the pins on the ends of the OAT probe wires into the included

connector housing until you are done running probe wiring through the aircraft.

The SV-OAT-340 connector is small and easily lost. One technique to avoid losing

this connector is to temporarily tape it to the top of the SV-ADAHRS-200/201 until

it’s time to insert the wires into the connector.

The following procedures apply to the both the primary and backup probes.

On the outside of the fuselage:

1. Drill a 3/8” hole at the installation location.

2. Feed the wires of the probe through the hole.

3. Feed the body of the probe through the hole.

On the inside of the fuselage (consider getting assistance for some of the steps below because

it may be difficult to be simultaneously on the inside and outside of the fuselage):

1. Feed the nylon washer over the cable.

2. Feed the nylon nut over the cable.

3. Feed the nylon washer over the body of the probe.

4. Hand-thread the nylon nut onto the threaded body of the probe. At this point, the nylon

washer should be sandwiched between the nylon nut and the inside of the fuselage.

5. Carefully tighten the nut using the 9/16” wrench.

6. Route and secure the probe wires to the location of the ADAHRS module. Keep wires

away from radios, ignition, and other noisy electronics.

7. Carefully insert the pins on the wires into the connector housing. Pins are not polarized

and lock into place when inserted correctly.

8. Connect the probe to the ADAHRS module.
