ESD

ESD SignThe electronic components and circuits are sensitive to ElectroStatic Discharge (ESD). When handling any circuit board assemblies, it is necessary that ESD safety precautions be observed.

ESD safe best practices include, but are not limited to:

  • Leaving circuit boards in their antistatic packaging until they are ready to be installed.
  • Using a grounded wrist strap when handling circuit boards.
  • Working on a grounded ESD table mat.
  • Only handling circuit boards in ESD safe areas, which may include ESD floor and table mats, wrist strap stations and ESD safe lab coats.
  • Avoiding handling circuit boards in carpeted areas.
  • Try to handle the board by the edges, avoiding contact with components.

This note is not an exhaustive information about the protection against electrostatic discharge (ESD).

1 General Information

The VCSBC 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 12 programmable input/output signals, with trigger input and flash trigger output, as well as a Gigabit Ethernet interface. Different CMOS sensors (the image resolution can be changed to the ROI required) with global shutter are available.

Some VCSBC nano Z Smart Cameras are also available with remote head (nano Z RH Series).

The extremely low power consumption of only 2.4W makes this camera ideally suitable for use in mobile devices.

2.2.2 Electrical specifications of the VCSBC nano Z Series Power Supply interface

Voltage/Current Overview
Nominal Voltage12 – 24 V
Nominal Power Consumption [1]2.4W
Minimum operational voltage (including ripple)9V
Minimum nominal Operating voltage and corresponding current12V, 184 mA [2] [3]
Maximum nominal Operating voltage and corresponding current24V, 99 mA [2]
Maximum operational Voltage (including ripple)30V
3.3V output maximum current100 mA
5V output maximum current100 mA

Power must be connected to pin 1&2 of the ST 1 connector.

Camera power is regulated, so only an unregulated power source of 12 V to 24V is required. The camera is, however, very sensitive to power supply interruption. Please make sure, that the voltage never exceeds the limits of < 9V, > 30V even for a short period of time. In case of trouble it is recommended to back up the power supply by a capacitor or a battery large enough to prevent power interruptions.

The camera may need more current for a short time at startup.


[1]Typical power consumption without using the onboard 3.3V supply.
[2](12) Current drawn from the 3.3V on board signal needs to be added to these figures.
[3]Power consumption may change with processing load and FPGA revision.

2.2.3 Electrical specifications GPIOs and I2C interfaces

Note

Note SignGPIO signals are LVCMOS 3.3V.

IO_0 – IO_11Digital LVCMOS (3.3V) programmable general purpose input / outputs
I2C_Clock and I2C_DataOpen collector 3.3V I2C serial Bus Interface for additional peripherals
RS232_TX and RS232_RXNative RS232 serial interface

The following Signals have a 4k7 pull up resistor on board: - I2C_Clock - I2C_Data

Warning

Warning SignThe I/Os are very sensitive (also to ESD) and not galvanically separated. Opto-isolation of the driving circuit is therefore strongly recommended. It is also recommended to keep the cable as short as possible!

Please note that the I/Os are not protected against over current. The I/Os are neither protected against short circuit nor reverse voltage spikes from inductive loads.

Note

Note SignUse the VC nano Z Series or the VC pro Z Series cameras if you cannot provide a suitable I/O driving circuit. These cameras include the same hardware as the VCSBC nano Z Series Smart Cameras, but overcurrent protection of the inputs and outputs is already included.

2.2.4 Electrical specifications trigger input and output

Note

Note Sign

Activation of trigger output is done by assigning the right GPIO via the command line tool named vcio, see GPIOs and Trigger Assignment for more information.

2.2.4.1 Trigger IO Specifications

The board features a dedicated fast trigger input (opto-isolated, for use as image capture trigger) and a fast trigger output (as strobe-light trigger). Since both signals are fast at a very low noise margin, it is recommended to keep the cable as short as possible. Use twisted pair or even coaxial cable for this purpose. The trigger input assures a constant image capture delay without jitter.

2.2.5 Realtime clock and backup battery

The board contains a realtime clock (RTC) with battery backup. The RTC is set during manufacturing to the current date and time. For backup a rechargeable lithium coin cell battery is used. This battery is charged to only about 10 percent of the nominal capacity on delivery and may be empty after a prolonged period of storage. We recommend charging the battery for at least 50 hours and setting the RTC (linux command: hwclock and date) when the board is first used (battery charges automatically when the system is powered on). The battery contains so little lithium, that it is not listed as a hazardous device for the environment and the flight export regulations. For details please refer to https://industrial.panasonic.com/ww/products/batteries/secondary-batteries/coin_rechargeable_lithium/coin-type-rechargeable-lithium-batteries-ml-series/ML621

Note

Note Sign

To check if the hardware clock is set appropriately, scan the output of the following linux shell command:

dmesg | grep rtc

One response line may contain the following message:

[ 0.322074] rtc-ds1374 0-0068: oscillator discontinuity flagged, time unreliable

This indicates low battery status or battery discontinuity.

To set the hardware clock it is necessary to set the software clock first:

date -s "2017-11-21 11:47:00"

Then the software clock time is transferred to the realtime clock by the following command:

hwclock -w

3.2 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. Sample usage instructions are provided here, but always refer to the instructions of your version:

VCIO v.1.2.3.- VCLinux Camera I/O Configuration and Connection Setup.

Usage: vcio [-s sen] [-i gpioNr] [-n] [-o gpioField] [-d gpioField] [-t time]

-sSensor to be configured, default value: 0.
-iGPIO Nr. to be used as external sensor trigger input (TRGSRC_EXT)
-nNegates trigger input signal
-oBitfield of GPIOs which are coupled with sensor trigger output signal. The bit of GPIO Nr. X is coupled, if Bit X is set to 1, for example, For coupling GPIO Nr. 0, 3 and 31 (TrigOut) provide the Bitfield as Decimal Value: 2^0+2^3+2^31=2147483657, as Hex Value: 0x80000009, or as Binary Value: 0b10000000000000000000000000001001.
-dThe direction of the GPIOs as bitfield (see -o switch); If the GPIO Nr. X should be configured as output, set bit X to 1, and if it should be an input, set bit X to 0.
-tTime used to debounce all input sources, default value: 10000. Time Unit is in FPGA Cycles. The FPGA clock frequency can be acquired by reading out the value of capt->sen->d.fpgaClkHz, e.g. 153846161 Hz. The default debouncing time for that example is then given by 10000 cycles / 153846161 Hz = 0.000065 s = 65 us.

Settings done cannot be read out. Different camera models may have different vcio parameters.

Example

Example SignIf an additional flash device is connected to Pin IO 1, the 'Connector Assignment of GPIOs' table shows the corresponding GPIO Nr.: 1. To link the gpio Nr. 1 to the sensor trigger signal, the 'vcio' program must make the gpio Nr. 1 an output gpio (-d) and couple it to the sensor trigger signal (-o), for example, the following call uses the TrigOut pin (gpio Nr. 31) and the IO 1 pin (gpio Nr. 1) for simultaneous flash output, the external input trigger is coming from gpio Nr. 10, which is, by table, the hardware pin of IO 10:

vcio -d 0b10000000000000000000000000000010 -o 0x80000002 -i 10

One can further switch flash outputs for each capture (see the libvclinux documentation: VCFlashSelector); therefore the corresponding gpios must be set as output (-d), but they should not be coupled with the trigger signal (-o), since this given value would be ORed with the flash selector settings, and the flash would always trigger.

Note

Note Sign

To actually use the trigger input source (assigned by the vcio program) you have to select it at your source code in your image capture struct by setting the capture trigger input source to TRGSRC_EXT (instead of TRGSRC_IMM for immediate trigger); refer to the libvclinux image acquisition documentation! You may also invert the trigger signal first, see Output Trigger Signal Inversion

3.2.1 Output Trigger Signal Inversion

One can invert the value of the trigger output signal by writing a 1 onto the corresponding GPIO nr, for example via the program 'vcgpio'. To get usage instruction for the program vcgpio run it without any parameters. The figure shows how it is applied.

VC nano Z I/O Circuit

4 OEM models with VC nano 3D Z FPGA

Some models are available with the VC nano 3D Z FPGA, for customers wanting to build a custom laser triangulation system using a VC camera and a separate laser.

Note

Note Sign

In this case, the whole GPIO configuration corresponds to the VC nano 3D Z GPIO configuration, see chapter 3 of the VC nano 3D Z documentation:


A laser can then be connected to OUT3, which can be activated as an additional trigger output. The standard trigger output is limited to a duration of 100 µs, using the alternative trigger output OUT3 allows to overcome this limitation.
