must be on the bottom. The label must be on the top. Figure 2 shows the correct orientation of
the ADAHRS as it would appear if you were above the aircraft, looking down at it. The module
will not operate properly if it is rotated or inverted in any other orientation.
There are no module-to-module proximity requirements when installing multiple
SV-ADAHRS-200/201 modules in an aircraft. For example, one SV-ADAHRS-
200/201 may be installed on top of another SV-ADAHRS-200/201 module. Other
installation location requirements still apply.
The ADAHRS installation location should also adhere to the following requirements:

Avoid locations that are lower than the lowest point in the pitot/static system to reduce the
chance of allowing moisture to enter the module.

Avoid locations that are subject to severe vibration.

Avoid locations that are subject to rapid changes in temperature.

Avoid locations that are subject to extreme humidity.

Leave ample working room for electrical and pneumatic connections.
SV-EMS-220/221
Observe the following guidelines when choosing a location for an SV-EMS-220/221 Engine
Monitor module:

Do not install on the engine side of the firewall.

Avoid locations that are subject to severe vibration.

Avoid locations that are subject to extreme humidity.

Leave ample working room for electrical connections.

Up to two SV-EMS-220/221s can be used in a SkyView Network, to support:

Large engines that require more than the CHT/EGT inputs available on a single SV-EMS-220
(14 CHT/EGT inputs) or SV-EMS-221 (12 CHT/EGT inputs) to fully monitor the engine; a
second SV-EMS-220 adds an additional 14 CHT/EGT inputs.

Independent monitoring of dual engines (requires two SkyView displays)
SV-GPS-250
Observe the following guidelines when choosing a location for an SV-GPS-250 GPS Receiver
module:

Optimal mounting location is a rigid surface on top of the aircraft.

Mounting location should be relatively level.

Avoid antenna shadows (i.e., obstructions that block the antenna’s view of the sky).

Do not locate the receiver within 3 feet of transmitting antennas.

All four of the SV-GPS-250 module’s wires should all be connected to each SkyView system
display for redundancy.

For most reliable performance, the SV-GPS-250 (like all GPS devices) requires a clear,
unobstructed view of the sky. The SV-GPS-250 is designed to be mounted on the upper
