Caution
Case may become hot!
The user is responsible to take care for an appropriate cooling.
To prevent the Argos3D-Pulse from overheating, it is strongly recommended, to keep away nearby objects. This
guarantees a constant airflow for proper cooling. This bounding box may be violated, when other cooling
techniques are provided.

4Interface Description
4.1 Signal naming
Signal names are usually written in capital letters. They are noted in positive logic (positive asserted). If the signal
is negative asserted an “n” will be added as prefix to the signal name.
Type:
The type describes the electrical characteristics of the signal. The following types are available:
•I Input
•O Output
•DN Negative Differential I/O
•DP Positive Differential I/O
•P Power supply
•LCVMOS33 Low voltage CMOS compatible signal with 3.3 V high level and 0 V low level.
•50 V tolerant Accepts input voltage levels up to 50 V (2.5 V logic high threshold)

4.2.2 Power supply
The power supply pins are protected against wrong polarity.
Although the operating input voltage range is between 18 V and 33 V, using a stable 24 V power supply unit is
suggested for best performance.
Note
Use inherently limited power sources only!
4.2.3 Power over Ethernet
Some derivates of the Argos3D-Pulse have the possibility to be powered via Power over Ethernet (PoE). The IEEE
802.3bt specification allows a maximum power consumption of 75 W.
Note
For Argos3D-Pulse types without PoE support an external Power over Ethernet adapter is
available. This can be used to operate the cameras on a PoE Plus (IEEE 802.3at) PSE. Please refer
to 8.1 for related products.

4.2.4 DIO
The digital Input-Output interface has an optical isolated input and output stage. Driven by the GPIOs 1 (output)
and GPIO 2 (input). See the Software User Manual specifications for GPIO functionality.
The output stage is a solid state relais, and gives the possibility to use the output as a simple switcher. The current
is limited to 200 mA.
If this interface is used as input, the corresponding output must be set to logically 0. Otherwise the input is
constantly shorted. The maximum LOW input detection voltage is 2 V, the minimum HIGH input detection volte is
5 V.
4.2.5 Trigger In
The trigger Input is not optically isolated to minimize the propagation delay. But the input is protected against
50V clamp voltages. A standard 3.3 V LVCMOS signal should be used. The corresponding ground reference is the
negative supply voltage (V-).
4.2.6 RS485 Mounting Option
For some Applications a RS485 communication could be needed. Therefore, the internal hardware could be
modified to route the RS485-A and –B signals to the connector in state of DI (RS485-A) and DIGND (RS485-B).
Ask BECOM Systems for custom modifications.
4.3 Mating Parts
The mating IP67 connector is an A-HDS15-HOOD-WP from ASSMANN WSW components GmbH and available for
purchase e.g. at Digi-Key.
An adjusted adapter cable is available from BECOM Systems.
4.3.1 Interconnection cable
A customized 5 m IP67 compliant cable is available from BECOM Systems. Please refer to 8.1 for related products.
4.3.2 Development Adapter
For development purposes there is an adapter available with standard Ethernet RJ45 interface and a 2.1 mm DC
power supply socket and for digital input, digital output and trigger input a two-pole header each.

The connector is used as section point.
2) Note
The maximum operating temperature depends on the frame-rate and integration time.
6.1.1 Input current
The average input current depends on the selected frame-rate (fps) and the integration time (tINT). The following
figure shows typical values. The values on the x axis shows the FITP which has been calculated with the following

The temperature on the casing can be reduced by mounting an additional heat sink on the cooling plate.
Caution
The user is responsible to take care for an appropriate cooling if the Argos camera is mounted
into a case.
Caution
Be careful to not stress the device beyond the limits, otherwise you may damage the device.
