1 Overview
This manual describes the usage of the ATOM one SSM500 (Super Slow Motion) camera
system.
ere is a quick navigation through the document:
•Chapter 1: Overview
Describes the functionality of the SSM500, especially the two different operational
modes, “Trigger” and “SSM”. Please read this chapter as a quick start guide on how
to work with the camera.
•Chapter 2: Technical Details
This chapter describes the internals of the SSM500 in detail and is of special
interest for system integrators.
•Chapter 3: General Usage
Gives information on how to connect the camera and describes the functionality of
the OLED display and the status LEDs.
•Chapter 4: Firmware Update
Describes the different ways that are available to perform a firmware update.
•Chapter 5: ProVideo GUI:
Short introduction into the ProVideo GUI which can be used to control the camera.
•Chapter 6 : Terminal Usage
Specifies the terminal interface of the camera and the way the camera processes
commands.
•Chapter 7 and following: Camera API
These chapters describe the commands that can be processed by the camera
grouped by subject areas.
1.1 Operation modes
The ATOM one SSM500 supports two operation modes:
•Tri er Mode: This mode uses the internal storage space to record and playback
slow motion video with up to 500 frames per second. This version can be used
stand alone.
•SSM Mode (Super Slow Motion 4x): This mode does not use the internal storage
but streams with 240 FPS via four D SDI (4x 1080p60) outputs This version is
intended to be used with external storage / video server solutions (like EVS).
The operation mode can be switched with the switch_mode command, which requires a
reboot. Details can be read in chapter 8.10.

7 of 95 Reference Manual ATOM one SSM500
1.2 Trigger Mode
In this mode the ATOM one SSM500 works as a stand alone camera with internal
recording.
It can record up to 500 frames per second with a memory depth of 30.000 frames. This will
give you a recording time of 1 minute at 500 FPS. By lowering the frame rate the recording
time can be extended accordingly.
It is possible to split the 30.000 frames in up to 4 smaller buffers on demand.
The recordin frame rate is independent of the video output format.
The slow motion ratio is defined by:
Slow Motion Ratio = Recording Frame Rate / Output Frame Rate
Examples:
Record 500 FPS / 1080p50 = 10x
Record 500 FPS / 1080p25 = 20x
In addition to that, the playback speed can be slowed down to further increase the ratio.
In trigger mode the camera has 2 independent output channels:
•Live
◦Always shows the live stream
◦The live frame rate is independent of the recording frame rate
◦Is shown on SDI outputs 1 & 2
•Playback
◦Can show the recorded slow motion video.
◦The slow motion factor is recording FPS / play back FPS
◦Optional it can show the live image if no playback is running (auto live)
◦Is shown on SDI outputs 3 & 4
SDI 5 is always showin a live ima e. This can be used by the camera operator as a
local monitor.
Both output groups have independent image processing pipelines for best flexibility for
color grading and post processing.
Refer to chapter 1.2.2 for workflows details.
Technical details on the Trigger mode can be found in chapter 2.1.
1.2.1 Production Preparation
For any production the camera needs some settings to meet the project requirements.
The following order is recommended:
1. Define lens system / lens control (motors, RCP, etc.)

8 of 95 Reference Manual ATOM one SSM500
2. Select the video output format, e.g. 1080i50
3. Select the recording frame rate / slow motion ratio, e.g. 300 FPS = 6x
4. Select number of buffers e.g. 3 x 10.000 frames (~33 seconds @ 300 FPS per
buffer)
5. Select the color profile on the live channel e.g. 6500K (playback will follow
automatically)
6. Setup white balance or use auto white balance
7. Start recording on a buffer
1.2.2 Tri er Workflows
Since the SSM500 Trigger does have multiple independent image processing pipelines,
the color workflow is different to other cameras.
This chapter defines recommended workflows for best results.
Trigger mode supports independent color grading for the live and playback channel.
Depending of the need for the production, 2 different workflow can be defined:
•Link Channels (live = playback)
•Pull Settin s (live → playback)
Important: Both work flows have in common, that the selection of the color temperature /
white balance is defined from the live channel.
This means that any recordin does include white balance from live settings at recording
time. Optionally the white balance can be modified/fine-tuned during playback if needed.
1.2.2.1 Link Channels
In the first workflow, both live and playback image processing are always in sync. The
operator must control only the live output, the playback output will follow automatically.
The command “link_settin s 1” links both channels, see chapter 7.9 for details.
Advanta es
•Very easy to use
•Record and play do always have the same look
•Low workload for the operator
Disadvanta es
•It is not possible to “tweak” the playback without changing the live image
•Risk: During playback, changes of live channel will show up directly “on air”
1.2.2.2 Pull Settings
In the second workflow, both live and playback image processing is independent. The
image engineer can control live and playback settings as wanted. In many cases one

9 of 95 Reference Manual ATOM one SSM500
image engineer is controlling the live image, while a 2nd engineer is controlling the
playback image.
On demand the playback operator can “pull” the settings from the current live image by
running a copy_settin s command, see chapter 7.8 for details. This command applies all
settings from the live channel to the playback channel.
Advanta es
•Full control over live and playback look
•Changes only get applied on demand, when the image engineer decides to do so
(lower risk of having wrong settings “on air”)
Disadvanta es
•igher workload for the operator (ideally two image engineers)
•Risk: Operator must make sure that settings get pulled, otherwise playback can
have wrong look
1.3 SSM Mode
In this mode the ATOM one SSM500 does not use its internal storage. The camera is
steamin in super slow motion speed with up to 240 FPS.
The slow motion ratio is changed by adjusting the number of active phases. There are 4
different phase settings possible:
•1 Phase: SDI 1 → 1x
•2 Phases: SDI 1, SDI 2 → 2x
•3 Phases: SDI 1, SDI 2, SDI 3 → 3x
•4 phases: SDI 1, SDI 2, SDI 3, SDI 4 → 4x
SDI 5 is always showin a copy of phase 1. This can be used for the camera
operator as a local monitor.
The frame rate is defined by the video output frame rate and the number of selected
phases.
FPS = Output FPS * umber of Phases
Examples:
Video Mode 1080p50 on 3 Phases:
FPS = 3 * 50 = 150 FPS
Video Mode 1080p60 on 4 Phases:
FPS = 4 * 60 = 240 FPS
From the image processing perspective, this camera is operated like any “normal” camera.
The image processors of all outputs are configured with the same settings, so no special
workflows are required.

2 Technical Details
2.1 Image Processing Pipeline – Trigger Mode
The following graphic gives an overview of the image processing pipeline in the ATOM one
SSM500 in Trigger mode:
The camera has two independent video processing chains. In the following chapters they
are called “live” and “playback”. Each chain features an image processor that can be setup
independent to match your video production needs.
The output video is send to three SDI outputs for the live chain (SDI 1, 2 and 5) and two
for the playback chain (SDI 3 and 4). Usually SDI 1 to 4 will be connected to the
production equipment while the 5th SDI output is used as a monitor output for he camera
operator.
The live and playback chain have independent video processors which can be configured
with different settings. To switch between the configuration of the live and playback chain
the out command is used.
In front of the two chains is a common module for global image processing tasks, this
includes the white balance and the defect pixel correction. Also the sensor settings like
gain and exposure time will be common for both chains.
The live chain directly plays back the video coming from the image sensor, it has a delay
of 1 frame.
The playback chain reads data from the video storage system. The storage system is
persistent, that means as long as you do not change the video format, the recording frame
rate or the amount of recording buffers (see video_mode, fps_mode and count
commands) you will be able to play back the recorded video even after a power cycle.
For more details on the handling of the recording engine please see chapter 17.
The playback chain can be configured to show a live image, if no playback is running (see
stop_mode command). In that case the image coming from the live video image

11 of 95 Reference Manual ATOM one SSM500
processor will be shown on all channels and the playback video image processor is being
bypassed (see the orange arrows in the above diagram).
Please note the following differences and dependencies between the live and playback
chain:
•The white balance settings (R/G/B gains) of the live chain are applied in the “Global
Image Processing” module, that means its’ settings also impact the playback chain
as they influence the data before it is being recorded. Changing the R/G/B gains of
the live chain after the recording was stopped will not effect the playback.
•The white balance settings in the playback chain can be used to fine tune the white
balance during playback. By default they are set to neutral so that the playback
chain has the same look as the live chain.
•The defect pixel correction happens in the “Global Image Processing” module and
always effects both chains.
•When being executed on the playback chain, the wb_preset command will set the
white balance gains back to neutral, but it will apply the color correction matrix and
offsets associated with that preset (see wb_preset command).
2.1.1 Recordin System
The recording system of the SSM500 consists of two high speed solid state drives (SSDs).
These drives have a limited lifetime, that means they can only be rewritten certain times
before failing. To ensure longevity of the SSM500 system, high endurance drives intended
for professional use have been selected. These drives have a write endurance of at least
2400 hours or 100 days of continuous recording at 500 frames per second. For an average
recording time of 3 hours per day, 7 days a week that translates into a lifetime of over 2
years.
You can monitor the state of the SSDs using the health command. If this command reports
any errors, or the video output shows image artifacts, please run a self test of the
recording system using the selftest command. Afterwards contact the Dream Chip
technical support so that the drives can be checked and replaced.
For more details please see the health and selftest command descriptions in chapter 8.
2.1.2 Workflow Details
This chapter is intended as a guideline on how to use the ATOM one SSM500 in a
production environment.
Note on Color Calibration and the White Balance:
To simplify the workflow the camera stores the currently configured white balance preset of
(see wb_preset command) and the currently configured white balance gains (see
ain_red / ain_ reen / ain_blue commands) of the live chain in the recording meta
data, when a recording is started with the rec command. When the recording is played
back with the play command these settings are restored automatically.
Caution: If the preset is changed during the recording these changes will not be updated
in the meta data, you have to select the correct preset before starting the recording.

12 of 95 Reference Manual ATOM one SSM500
Since the global white balance is done before storing the video data (see chapter 2.1), the
recorded video data is already white balanced. Therefore the white balance gains of the
playback chain will internally be set to x1 when playback is started. This ensures that the
playback has the same look as the original live video.
To show the correct white balance gains that were used during recording, the camera
stores the white balance R/G/B gains when the recording is started and will display those
when the buffer is being played back (although internally a gain of x1 is used).
You can change the white balance of the live chain during the recording, or use the AWB
and those changes do have an immediate effect on the recording, but they will not be
stored in the buffer meta data. That means when playback is started, the camera will
report the initial values of the R/G/B gains. Any updates made later will not be reflected in
the values reported by the ain_red / ain_ reen / ain_blue commands.
If you are not satisfied with the white balance or color calibration during playback, you can
select a different preset using the wb_preset command or change the white balance gains
(ain_red / ain_ reen / ain_blue commands) while the playback is running. These
settings are only temporary and will be reset to the values stored in the buffer meta data if
you stop/restart playback or play back a different buffer.
2.1.2.1 orkflow A: Independent Live and Playback Chains
As described in chapter 2.1 the live and playback chains feature their own image
processor. By default these are configured in a split configuration, that means they can
configured independently.
The image engineer can use this to perform all changes on the live chain (by setting the
out command to 1). is changes will not effect the playback output which might be on air
at the same time.
Once the setup is complete and the playback output is not on air anymore the
copy_settin s command is used to copy all settings form the live to the playback chain to
apply the new look for the next playout.
If corrections have to be made to the playback output without wanting to change the live
output the playback chain is selected by setting the out command to 2. Please note that
there is no command to copy settings from the playback to the live chain.
2.1.2.2 orkflow B: Linked Live and Playback Chains:
If the above workflow is not desired or to complicated, both chains can be linked by using
the link_settin s command. If link_settin s is enabled both chains will be configured at
the same time, regardless of the current setting of the out command.
One important exception are the ain_red / ain_ reen / ain_blue commands used to
setup the white balance: Since the global white balance is done before the recording, the
recorded image data is already white balanced. Therefore changing the white balance of
the live chain will not change the white balance of a recording that is currently being
played back, even when both chains are linked. If you want to fine-tune the white balance
of an existing recording, you have to switch to the playback chain using the out command
before sending the ain_red / ain_ reen / ain_blue commands.

For a full list of the commands that will be executed on both chains in linked mode see the
description of the link_settin s command.
Linking the chains will always result in an implicit call of copy_settin s, so that the chains
are initially in sync. From here on you can setup both chains simultaneously, just
remember that any setting will directly be seen in the playback output.
2.2 Image Processing Pipeline – SSM Mode
The following graphic shows the image processing pipeline of the ATOM one SSM500 in
SSM Mode:
In contrast to the Trigger Mode the SSM Mode does not have a recording pipeline as
recording is done by an external solution (e.g. EVS). The SDI outputs 1 to 4 contain the
multiplexed slow motion video with up to 60 fps per output (240 fps sensor frame rate) and
will usually be connected to the storage system.
The 5th SDI output is a copy of SDI 1 and serves as a monitor output for the camera
operator.
It is possible to change the number of active phases to reduce the amount of SDI outputs
used (and thus reduce the slow motion factor). For more details see the phases
command.
2.2.1 Workflow Details
Since the ATOM one SSM500 in SSM Mode has only one video processor and no internal
recording it behaves like any other ATOM one camera and you can use your usual
workflow.

3 General Usa e
For regular operation the camera only needs a power supply. For controlling the camera a
RS485 connection is required.
This can be done with the optional RS485 USB converter. Connect the USB connector to
your PC and let the operation system install the required drivers. You can then use the
ProVideo GUI software to control the camera (see chapter 5).
Alternatively you can use a third party hardware controller to control the camera.
3.1 Power On/Off
After connecting the power cable, the camera will turn on automatically and the Sys LED
begins to blink green. The boot process takes about 20 seconds and is being visualized in
the OLED display. During boot the fan will spin at maximum speed.
If the camera has been turned on and the power is interrupted, the camera will turn on
again automatically once power is supplied again.
To power down the camera press the power button for ~3 seconds or use the shutdown
command. During power down the fan will spin at maximum speed. The camera will then
enter standby mode.
In standby mode the Sys LED glows yellow. To turn the camera on again, press the power
button for ~3 seconds, or cut the power for at least 5 seconds before reconnecting it.
Note: It is recommended to shut down the camera with the power button or shutdown
command at the end of a production to ensure no corrupt image data is stored.
3.2 Connectors
The ATOM one SSM500 has two 6 pin irose R10 connectors.
1. Main: Male R10 6 pin

3.2.3 Microphone Input
The microphone connector is a standard 3.5 mm stereo jack. It supports 2.5 V phantom
power for electret microphones (see audio_micbias command for details).
The audio will be inserted into all SDI signals.
3.2.4 RJ45 Ethernet Connector
The network connector is reserved for future applications like control via IP. At the moment
it can only be used for firmware updates (see chapter 4.2).
3.2.5 SD Card Slot
The ATOM one SSM500 has a SD card slot on the right side. This slot is used for firmware
updates. Details can be found in chapter 4.3.
3.3 Over-Temperature Protection
The ATOM one SSM500 has a compact design which includes an efficient air cooling
solution. Still the device will get warm during heavy load. To protect the device the camera
will switch to a low power state when the internal CPU temperature reaches 90°C. This
stops all record and playback and powers down the image processor.
To recover from this state the device temperature has to fall below 70°C Keep in mind that
as long as you did not improve the cooling the camera will probably reach the temperature
limit again after a short time.
If the low power state does not cool down the camera and the temperature reaches 100°C
the device will shut down completely. You can only recover from this state by turning the
device on again via the power button.
Note: During normal operation the camera should never reach the 90°C limit. If your
device reaches this limit repeatedly, please check the operating conditions (e.g. ambient
temperature, other devices generating heat nearby, access to fresh air for cooling).
To keep track of the current CPU temperature use the temp command. The camera also
logs the maximum CPU temperature which can be read out using the max_temp
command. You can reset the logged maximum temperature using the max_temp_reset
command.
Every time the camera reaches the 90°C temperature limit, an over temperature counter
will be incremented. You can read the counter value by using the over_temp_count
command. This counter value is persistent and can not be reset by the user.
3.4 Status LEDs
The device has two status LEDs.
The right LED labeled “Sys” shows the general status of the system:
