1   General Information

The VC nano Z Series Smart Cameras have been designed for high resolution image processing with a very small form factor. They are the ideal compromise between high performance and low system costs, and thus especially suited for high volume OEM applications. This makes them viable to use a smart camera in even more products than before.

Based on a dual-core processor ARM® Cortex®-A9 with 866 MHz and an integrated FPGA the models of the new VC Z series offer solutions at extreme high-speed in real-time.

The operating system VC Linux provides for the ideal interaction of hard- and software.

All cameras are equipped with a battery backed real time clock and come with 2 inputs and 4 outputs, with trigger input and flash trigger output, as well as an Ethernet interface. 5 different CMOS sensors (the image resolution can be changed to the ROI required) with global shutter and a resolution up to 4.2 Megapixel are available with all models.

The extremely low power consumption of only 1.7W makes this camera ideally suitable for use in mobile devices.

3.2.2   Electrical specifications Camera Power Supply

Warning

Warning Sign With the VC nano Z Series cameras the PLC supply contacts are internally connected with the camera power supply pin 2. In this case pin 1 and 9 require the same voltage level as the camera power supply pin 2. Refer to section 4.2.3 for details on the different PLC interface features.

Voltage/Current Overview
What How much
Nominal Voltage 12 – 24 V
Absolute Voltage Limits 9 V - 30 V
Minimum nominal Operating voltage and corresponding current 12V, 160 mA
Maximum nominal Operating voltage and corresponding current 24V, 90 mA
Nominal Power Consumption 2.2W

In general the camera power supply is regulated in the camera, so an unregulated power source is sufficient. However the absolute voltage levels specified above should never be exceeded.

In case of unstable power supply (voltage spikes or power interruptions) it is recommended to back up the power supply by a capacitor or a battery large enough to prevent power interruptions.

It is recommended to switch on the low voltage supply (12 to 24V) when booting the camera. Some 110/ 220V power supplies increase the output voltage too slow or drop the voltage under load at startup which might cause the camera not to boot properly! A power supply able to supply a much higher than nominal boot current for a few milliseconds may be an alternative approach.

3.2.3   Electrical Specifications digital PLC IO / trigger Interface

The VC nano Z Series Smart Cameras feature digital inputs and outputs that allow e.g. direct input of light barriers signals or the control of pneumatic valves, as well as a trigger input and output.

Please observe the current and voltage ratings specified in the following sections.

Electrical Specifications
Separation of PLC/trigger output voltage Warning Sign PLC outputs supply not separated from power supply
PLC/trigger Input Voltage Identical with power supply voltage
PLC/trigger Input Current (max) 1.0 mA at 12V to 2.0mA @ 24V
PLC/trigger Output Voltage Identical with power supply Voltage — internally connected
PLC/trigger Output Current (max) 4 x 400 mA Max total of all outputs: 1A
Max Current for 1 Power / PLC connector pin 500 mA
Power failure detection

Warning

Warning Sign When using the PLC/trigger outputs connect all camera supply and PLC supply pins (pin 1, pin 2 and pin 9) in order to limit the connector pin current.

The maximum combined current of all outputs should not exceed 1 A.

4.2   Trigger Assignment

To choose the sensor input/output trigger signals, the corresponding GPIO Nr. must be determined and assigned by the supporting program named vcio. More information can be found at the help of the program, if you run it with no command line parameter, it will show how to do it. For using this external trigger input source refer to the libvclinux image acquisition documentation.

The image is formed by a 1.3 megapixel CMOS sensor (VC nano Z 0011). The image is then stored in the DDR3-SDRAM memory, which has been increased to 512 MB.

The VC nano Z Series cameras do not have a direct video output. However if monitoring of the camera image is required, this can be done by transferring via Fast Ethernet port to PC and display on screen.
