3. Measure the +28 VDC input voltage to the HGA at A1-P1 V and Y to A1-P1
P and S.
4. Measure the +28 VDC input voltage to the DLNA at A2-P4 G to A2-P4 K.
5. Switch OFF the breaker to the antenna subsystem components.
6. Connect the +28 VDC supply cable to A1-J1 and A2-J4.
Perform manufacturer-specific satellite communication avionics tests.
Honeywell recommends towing the aircraft in a figure eight pattern or 360° circle
while monitoring signal strength received by the Aspire-200 to verify the
antenna operation.
4. Electrical Installation
For details about electrical installation, refer to the Aspire System Interconnect Drawings in Figure 4-3 to
Figure 4-6, starting on page 4-13.
A. Remote Lamp Driver Circuit Requirements
Figure 4-2 provides the circuit requirements for Remote Status Lamp drivers. Each
lam
p driver circuit provides an
open-drain Field-Effect Transistor (FET) interface
that has a maximum continuous drain-to-source voltage of 35 VDC and
drain-to-source current of 0.5 A DC. These circuits are designed to sink current to
ground only. Any external lamps connected to these driver circuits require the
appropriate external voltage and series impedance to be connected.
