Exposure Sequence
To learn more about the capabilities of the iXU-RS 1900 camera,
consult the http://industrial.phaseone.com/Aerial_Systems.aspx
website and the document files saved on the USB drive
provided with the camera.
Understanding the Exposure Sequence
There are three signals that are used to communicate with
and control the iXU-RS 1900 exposure sequence:
• Trigger in: The Flight Management System (FMS) signals
the iXU-RS 1900 to take an image.
• System ready: Camera ready/busy signal.
• Mid-exposure pulse: A signal indicates the midpoint of the
exposure time.

Black Reference Sequence
Understanding Black Reference
A black reference is the process of reading the sensor output
during an exposure without the sensor being exposed to
light. This data is written to the camera and used to subtract
from the regular capture.
Updating the black reference data whenever it is possible
enhances the image quality, in particular when shooting in
conditions where the temperature of the camera changes. If
the exposure time varies a lot, the black calibration reference
data should be updated.
It is advisable to make a black reference capture before
starting your first flight line and if the exposure settings
or ISO have been changed. This ensures the accuracy of
exposures. The best time to do this is before starting a new
flight line, when images are not being captured.
Note: Black reference is performed automatically on taking
the first shot after switching the camera on.

Hardware Activation of Black Reference
If you are building your own hardware control box, you can
update the black reference data in the camera. The black
reference control signal should be kept low while an image
capture cycle is initiated. The signal must remain low for the
full capture cycle. This makes it possible to create a black
reference whenever it is convenient (i.e. when turning an
aircraft around or between flight lines). When the force black
signal is kept high, the camera uses the last updated black
reference data.
Software Activation of Black Reference
The Phase One iXU-RS 1900 camera can perform a black
reference sequence by using the iX Capture application, the
Phase One SDK, the Flight Management System or through
an iX Link API.
When using iX Capture, simply click Black Ref on the iX
Capture dashboard to update the black reference.
Wiring a Control Cable for an iXU-RS1900
External devices are connected to the camera with an iXU
RA control cable (supplied with the camera kit). This cable
has a LEMO-secured connector on one side for the camera
and an open side with nine (28 AWG) wires for connection to
your system.
The table below describes the functionality of the wires in
the iXU RA control cable.

5. Connecting a Camera
Attaching the Camera to a Pod
Attach the iXU-RS 1900 camera to a pod using six M4 bolts.
Note: Do not insert bolts deeper than 6 mm into the threaded
holes on the front of the camera.
Connecting a Control Cable
1. Insert an iXU RA control cable into data terminal A of the
left sensor module, on an iXU-RS 1900 camera.
2. Connect the other end of the iXU RA control cable to an
external device (GNSS and/or FMS).
3. Insert an iXU RA 30 cm multi-sync cable into the sensor
module's data terminal B (left sensor module).
Note: The two data terminals are not interchangeable.
Connecting the Power Cable
To connect the camera to the aircraft's power bus:
1. Insert the iXU RA power cables to the power input of the
two sensor modules of the iXU-RS 1900.
2. Connect the other end of both iXU RA power cables to the
aircraft’s power bus.
Note: When not in use, disconnect the power from the sensor
modules.

2120
To connect your iXU-RS 1900 to external devices:
1. Insert the iXU RA control cable into data terminal A
of the left iXU-RS 1900 camera body.
2. Connect the other end of the iXU RA control cable into the
GNSS/FMS.
Note: ensure that the camera and all connected devices are
connected to a power source.
Connecting Control Cables to Devices
Depending on how you choose to configure your iXU-RS 1900,
the camera can be connected to the following:

Connecting a USB 3.0 Cable to an
Onboard Computer
To connect a USB 3.0 cable to a computer:
1. Using a 2 mm hex key, unscrew the screw on the cover of
the USB 3.0 port.
2. Remove the cover with screw and store it.
5. Connect the other end of the USB 3.0 cable into the USB
port of your iX Controller or on the back of your onboard
computer.
6.Repeat for the second sensor module.
3. Insert the end of the USB 3.0 cable into the USB 3.0 port
on the camera.
4.Using a 2 mm hex key, tighten the screw on the USB 3.0
cable lock into the camera.

2726
Connecting a GNSS/IMU
Connecting a Phase One camera to a GNSS/IMU involves
three steps:
• Physical connection of the camera to the GNSS
• Configuring the camera
• Configuring the GNSS/IMU
In order to facilitate communication between your Phase One
aerial camera and a GNSS receiver, the parameters in your
GNSS receiver and camera must match.
Note: The GNSS receiver must use the same baud rate as the
camera (9600, 19200, 57600 or 115200).
A comprehensive guide to connecting Phase One aerial
cameras with a GNSS receiver is available for download from
http://industrial.phaseone.com/downloads-guides.aspx

9. Firmware
The camera's LCD screen displays technical information
about the hardware and embedded firmware of the camera.
This is especially useful if support is needed or if you want
to check if Phase One is oering a newer firmware update.
Please make a note of the firmware menu contents before
contacting your dealer or Phase One Support.
Checking the Firmware Version
In order to determine if you have the latest firmware installed:
1. Go to Menu > About System.
2. Check to see if the firmware version installed on the
camera is the same as the latest version available in the
Downloads section of industrial.phaseone.com website.
About the Phase One Firmware Updater
Application
The Phase One Firmware Updater application is used to
update your Phase One aerial camera with new firmware.
The Firmware Updater is available in the Downloads section
of the industrial.phaseone.com website.
The Firmware Updater does not in itself contain any firmware
— it detects the camera attached, checks online for the latest
firmware and retrieves and installs the firmware packages for
your device.
Check the Firmware Updater Application Installation Guide
for detailed instructions on oine methods of firmware
updating.
Installing the Firmware Updater
Application
To install the Phase One Firmware Updater Application,
download it from the Downloads section of the
industrial.phaseone.com website and do the following:
1. Open the zip file, extract and store the FWUpdater.msi.
2. Double-click FWUpdater.msi to start the Firmware Updater
Setup Wizard.
3. When installation completes, click:
Start > Phase One > Firmware Updater.

3130
2. Start the Firmware Updater application.
3. The Firmware Updater automatically checks online for a
new version of firmware and displays a download button if
your camera requires an update.
4. If displayed, click the link to download the firmware.
The firmware is saved locally.
5. From the Select Firmware dropdown menu, select the
firmware that you want to update.
Updating the Firmware
Before starting, ensure that:
• The sensor modules are connected to power supplies and
are powered on.
• Your computer has the Firmware Updater application
installed and the computer is connected to the Internet.
To update the iXU-RS 1900 firmware:
1. Connect the sensor modules to a computer with USB 3.0 cables.

3332
6. After downloading the new firmware, the Release Notes
button is no longer grayed out.
7. Click the Release Notes button to download the release
notes for the newest firmware.
8. To update the sensor module to the latest firmware, click
Update.
The firmware is written to the sensor module and a gear
icon is displayed next to the MAIN component and a
progress bar displays the progress of the update.
9. Upon a successful completion of the update, the MAIN
component is marked with a green check mark icon.
10. If the update fails, disconnect the USB 3.0 cable, reconnect
it, and repeat the procedure described above.
11. Repeat the same for the second sensor module.
Warning: Don’t disconnect the USB or Power cables before
firmware update is completed”
Restoring the Firmware
In the event you need to restore the sensor module’s
firmware to the factory version. (sensor module settings are
not aected):
1. Go to Menu > Firmware.
The Firmware screen appears.
2. Select Restore Firmware.
3. Click Restore to Factory Default.
The original factory firmware is installed.
