1Handling and Safety Instructions
Depending on the operating conditions, the housing temperature can exceed
60 °C. There is a risk of injury!
Handle with care! The housing, especially heat sinks, can have sharp edges. There
is a risk of injury!
EMC conformity according to EN/IEC 61000-6-2:2005 is qualified for cable lengths
≤ 30 m.
Electrostatic discharge at unshielded I/O connectors can lead to unexpected
events or data errors for the corresponding interface.
Electrical installation should be executed without power applied to the device
and connected devices.
Before opening the housing, make sure that the VisionBox is disconnected from
power.
Use appropriate ESD protection when changing components.
Please take special note of the voltage range which may be applied to the device.
Otherwise, permanent damage to the device may result!
Air Circulation
When mounting the device within an enclosure, adequate space for air circula-
tion is required. The space above, below and at both sides should be at least 5
cm.
Avoid extreme environmental conditions and protect the VisionBox from dust,
humidity and heat.
Due to the characteristics and physical principles inside flash memory, SSDs have
a finite lifetime dictated by the number of write operations.
Therefore, take care of the regular write operations to prevent an early SSD
damage. Ask for the technical data of the used SSD and, if necessary, for support
to calculate the lifetime.
Inform the user of the system that SSDs are wear parts which must be renewed
regularly.

2Introduction
Thank you very much for your interest in our VisionBox DAYTONA. To get the most out of your
purchase, please take some time to read all the information given here thoroughly.
The VisionBox provides three Gigabit Ethernet ports and two USB 3.0 ports. To avoid complex
cabling, two Ethernet ports have support for PoE and the GigE Action Command. This allows
transferring data, power and trigger signal using a single Ethernet cable.
The integrated Real-Time Communication Controller (RTCC) ensures proper timing for trigger sig-
nals, even without any real-time operating system. The IMAGO SDK provides a consistent C++
programming interface for controlling the RTCC.
Due to its small size, powered by 24VDC and without fan, the VisionBox can be mounted into near-
ly every machine. All components are available for several years, for continuous delivery without
changes. For series production, IMAGO delivers the VisionBox ready-to-run, including a customer-
specific root filesystem, qualified 3rd-party components and acceptance test.

Note: The maximum allowed temperature is influenced by the actual hardware configuration,
the system workload and the mounting situation. The temperature range should be veri-
fied for each application.
Note: The heat sink can transfer more heat in upright mounting position.
Note: Due to the lifetime of electronic components (laws of physics say: if the average operating
temperature is increased by 7°C, the lifespan of an electronic component will be cut in
half), we recommend not to operate the device permanently under the maximum possible
temperature and instead use a lower than max temperature. It is recommended that the
application software regularly checks internal temperatures.

The listed range applies to different CPU / GPU workloads while using DisplayPort and a single Gigabit Ethernet con-
nection. The use of additional interfaces and supply of connected USB and PoE devices is not accounted for.

5.1.1 Power-over-Ethernet
Ethernet ports 1 and 2 can provide power to PoE devices using the IEEE 802.3af/at standard.
5.1.2 Trigger-over-Ethernet
The ToE feature adds support for the GigE Vision Action Command on Ethernet ports 1 and 2. It
can be used to trigger cameras over Ethernet in real time. The GigE specification allows sending
these messages by a different device, distinct from the primary application, which normally runs
on the main CPU. A sideband interface allows the Real-Time Communication Controller to intro-
duce packets into the network:

Two different Action Commands can be defined by the application. Please note that Action Com-
mands don’t belong to any port. All Action Commands are broadcast on all four ports.

5.2 USB 3.0
Figure 5: USB 3.0 port
The VisionBox provides two USB 3.0 type A ports. The supported maximum speed is 5 Gb/s. Based
on the USB specification, each port can deliver 900 mA.
5.3 Micro USB Service Port
Figure 6: Micro USB service port
The micro USB service port only supports device mode operation. There are two use cases:
•If a PC is connected to the micro USB port during power on, the VisionBox enters USB re-
covery mode. This is indicated by a green blinking ON LED. Only use this mode if advised
by IMAGO. Do not try to flash the Jetson OS image provided by NVIDIA!
•If a PC is connected after the VisionBox has already booted, the following USB device func-
tions are supported by the Linux OS:
oEthernet: Provides SSH access, used by NVIDIA SDK manager for installation of SDK
components.
oUART/Serial interface
oUSB Mass Storage device
Important note:
The micro USB signals are shared with the first USB 3.0 port. The USB signals are internally
switched to the micro USB port if a host is connected and providing the 5V USB supply voltage.
Therefore, any devices connected to the USB 3.0 port 0 should be removed before plugging or
unplugging the micro USB host cable during runtime. Otherwise, the integrated USB host control-
ler may fail to operate.

5.4 DisplayPort
The DisplayPort 1.2a interface supports a link speed of up to 5.4 Gbps with 1, 2 or 4 lanes. The
maximum supported resolution is 3840 × 2160 at 60 Hz. To connect the DP Port with a DVI, HDMI
or VGA monitor, an active adapter is needed.
Figure 7: DP connector
5.5 SD Card
The SD card socket supports SDHC and SDXC memory cards with a maximum interface speed of
104 MB/s (UHS-I).
Figure 8: SD card socket
5.6 Wi-Fi and Bluetooth
Two SMA connectors are shared between Wi-Fi and Bluetooth. Two antennas are used for
IEEE802.11n/ac Wi-Fi modes. The connectors are of type female RP-SMA.
Figure 9: Wi-Fi SMA connectors
5.7 4G / LTE Modem
The VisionBox can optionally be equipped with a 4G / LTE modem. One or two female SMA con-
nectors are then available.

5.8 Digital I/O
The digital I/O interface provides an input and an output group, each containing eight signals. The
input group is electrically isolated from the output group. Both groups are also isolated from oth-
er VisionBox circuits and interfaces.

The input group requires an external connection of a shared GND reference. For the output
group, the user must provide a supply voltage to the VCC pin which is used by all output signals.
Every input and output have an LED to show the current state of the channel.
