The SCOTTY Group and Diamond Airborne Sensing present a versatile and
efficient surveillance solution: the SCOTTY/Diamond DA42 Multi-Purpose
Platform (MPP). This twin-turboprop has been outfitted with an observation
camera and a beyond line-of-sight satcom link.
The video of the observation camera can be recorded locally in full TV quality,
and/or sent to a control station in real-time over the satellite link. By combining
up to four INMARSAT Swift64 satellite channels, video rates up to 256 kbit/s
are possible, using the latest video protocol H.264 to achieve the maximum
video quality.
The full setup consist of following components:
•Diamond DA-42 MPP airplane
With its long-range capabilities ideally suited as an airborne platform for
surveillance operations.
•SCOTTY SATCOM Rack DA-42 MPP
The video processing and communication unit integrating these functions:
• INMARSAT satellite modem
• Windows compatible computer
• Live video processing hardware
• High-quality video recorder
• System control and maintenance software
•Antenna subsystem for communication with the INMARSAT satellite
network
•Controllable camera with optical and FLIR capabilities
•Operator console, including video monitors, camera control panel,
keyboard and mouse
•Inertial Reference System as reference for the antenna positioning

The central unit of the overall SCOTTY DA-42 MPP System is the SCOTTY
SATCOM Rack, shown in Figure 6, part number SD205198A.
It receives the video from the video subsystem, gets the aircraft position from
the IRS subsystem, and controls the satellite antenna.
The SATCOM Computer controls the other units. It features built-in video
encoders for live transmission and hard disc storage.
In order to expand the system, several additional video, audio and data inputs
and outputs are available.
For the location of the connector on the rack, see Figure 8.

3.2 Mechanical Drawings
This chapter shows the mechanical drawings of the SCOTTY SATCOM Rack.
For mechanical drawings of the other components, refer to the documentation
of the corresponding equipment.
Figure 7 displays the outline of the rack.
The location of the connectors is shown in Figure 8.

4 Diagnostics
4.1 EMSHSD SW
The EMSHSD software is software installed on the SATCOM Rack. It allows
easy access to the INMARSAT transceiver, one of the major parts of the
SATCOM Rack, for setup purposes, and for diagnostics of the overall system.
The software can be started directly from the Windows Desktop.
Figure 9: The SCOTTY EMSHSD Software
The field System shows the time and date of the transceiver.
Flight Information displays the current IRS information, as received by the
transceiver from the SCOTTY IRS system. Please note that the Heading
displayed is the true heading, not the magnetic heading.
Satellite shows the INMARSAT satellite that is selected at the moment,
together with the azimuth and elevation data for the antenna pointing.
Maintenance Manual 17

SCOTTY DA-42 MPP Rack
The status of the four channels is shown in the section Channels:
The column Status displays the current status of each channel, like “orr”
(registration in progress), “no call” (channel is idle), “data” (data call), or “no
dial” (channel is not available).
The current signal level is displayed in the column C/No. The signal level
should be greater that 48 dB/Hz for stable calls.
The temperature of the channel card hardware is shown under Temp.
During a call, Frequency displays the uplink frequency.
The line after each channel’s information columns shows detailed call status
information for the channel, like call type details, call direction (mobile or
fixed), error text when a connection is terminated, and status information
during the registration process.
Start Capture captures the raw data status data received from the SATCOM
transceiver, e.g. for diagnostic purposes.
The Open Terminal button opens a second window, which enables direct
access to the SATCOM transceiver’s maintenance port. Setup and advanced
diagnostics are possible by using the terminal window.
Please refer to the SATCOM transceiver manual “MN-1252-30089 EMS HSD-
400 High-speed Data Terminal” for a description of the menu system,
especially chapter “Test and Fault Isolation”.
18 Maintenance Manual

SCOTTY DA-42 MPP Rack
4.2 Fault Isolation
1. Go through the troubleshooting steps defined in the “DA-42 MPP Rack
Maintenance Manual”, part number SD205864A.
4.2.1 Boot Up Issues
If the system does not boot up, check following points:
1. Check the power LED of the computer system.
2. Check if the computer display is powered and switched on.
3. If Windows starts to boot up, but then the display gets dark, try to press
CTRL+ALT+F1.
4. Recover the PC system, see “DA-42 MPP Rack Maintenance Manual”.
4.2.2 Connection Issues
The EMSHSD software makes it easy to isolate faults on a sub-system basis.
1. Check the Fault LED of the SATCOM transceiver. If it is red, check the
INMARSAT transceiver with the EMSHSD Terminal window (see
transceiver manual).
2. In the EMSHSD software, check the “C/No” indication.
3. If “C/No” if low, check the IRS information displayed in the EMSHSD
“Flight Information” filed with the aircraft’s IRS data. Please note that
the EMSHSD software displays true heading, not magnetic heading.
4. If a deviation in the IRS data exists, the IRS system could be the
problem. See chapter 6 Calibration for next steps.
5. If no IRS data are displayed, check the IRS subsystem.
6. If IRS data are OK, but C/No is low, use the “Satellite” information
displayed in the EMSHSD software, and check that a visible satellite is
selected, and that azimuth and elevation are pointing towards open sky.
7. If IRS data are OK, but C/No is low, check the antenna subsystem.
8. If “C/No” is OK, check the “Status” of the channels.
9. If Status indicates “no dial”, check the INMARSAT transceiver with the
EMSHSD Terminal window (see transceiver manual).
Maintenance Manual 19

SCOTTY DA-42 MPP Rack
10. If Status indicates “no call”, even when dialing up a connection, check
the ISDN of the SATCOM Computer system.
11. If the Status changes to “data” when placing a call, but the call does not
connect, check the INMARSAT registration:
a. Reset the INMARSAT transceiver by pressing the “Test” button
on front of the transceiver.
b. Use the EMSHSD software to verify successful registration
(some retries might occur)
c. If registration is not successful, check the antenna subsystem,
especially in TX direction.
d. If registration is successful, the INMARSAT account could be
blocked. Contact the service provider.
