1 General Information

VCSBC4012 Single Board Camera

The VCSBC4012 has been designed for high resolution image processing with a very small form factor. The VCSBC4012 is the ideal compromise between high performance and low system costs, and thus expecially suited for high volume OEM applications. This makes it viable to use a smart camera in even more products than before.

Employing a CMOS sensor, the image resolution can be changed to the ROI required.

Like with all VC Smart Cameras with Texas Instruments DSP, the operation system VCRT allows multi- tasking. This means for instance that user interface commands can execute in parallel without stopping the inspection process. It is also possible to transfer live images via TCP/IP using a background task.

The VCSBC4012 camera offers an inexpensive entrance into the world of the high performance intelligent cameras. It has a video output onto a PC via 100MBit Ethernet interface, a high speed trigger input and output, 12-24 V digital Inputs and open collector outputs and additional TTL IOs.

The extermely low power consumption of only 1.5W makes this camera ideally suitable for use in mobile devices.

VCSBC4012.pdf – VCSBC4012 Single Board Smart Camera Operating Manual 5

2 Basic Structure

The image is formed by a high-resolution 5 mega pixel CMOS sensor. The image is then stored in SDRAM memory, which has been increased to 64MB, due to the large camera image.

Unlike most other Vision Component Smart Cameras, the VCSBC4012 does not have a direct video output. However if monitoring of the camera image is required, this can be done by downloading via Fast Ethernet port to PC and display on screen (see

“Image Transfer” demo software under

“Support -> Customer Area -> Software Utilities”

The TMS320C64xx DSP is one of the fastest 32bit DSPs. It features a RISC-like instruction set, up to 8 instructions can be executed in parallel, two L1 cache memories (16 Kbytes each) and a 128 Kbytes L2 cache on chip. Its high speed 64-channel DMA controller gives additional performance. The DSP uses fast external SDRAM as main memory. A flash EPROM provides non-volatile memory.

4.1.2 Electrical specifications digital IO s J1 interface

The camera has two PLC compatible inputs and four PLC compatible open-collector outputs for controlling machines and processes.

Inputs and outputs are not galvanically separated from the supply voltage.

A protective diode ensures, the poles of the supply voltage from the power supply of the PLC can not be swapped. The outputs are floating when high – external pull up resistor required.

According to matching Power / PLC Cable VK000173

Maximum operational Voltage (including ripple): 30V

Power must be connected to the 12 pin J1 I/O 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 backup the power supply by a capacitor or a battery large enough to prevent power interruptions.

4.2.3 Electrical specifications J2 camera socket

All Signals are Low Level TTL (3.3V), not opto isolated. The electrical specifications given for the trigger input and output are also valid for the remaining LVTTL IOs.

The following Signals have a 1k5 pull up resistor on board:

I2C_Clock

- I2C_Data

- Trig_in

Trigger IO Specifications:

The board features a dedicated fast TTL trigger input (for use as image capture trigger) and a fast TTL 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.

Electrical Specification of trigger input

input voltage: Signal LOW -0.3V – 0.8V (LVTTL) Input voltage: Signal HIGH 2V – 3.9V (LVTTL) input current: N/A limiting resistor: 1K5 pull up reverse voltage protection: none switching delay: none

Image trigger on rising or falling input signal works as before – see section 6.5.1 for details.

The trigger input and output are very sensitive and not galvanically separated. Opto isolation of the driving circuit is therefore strongly recommended. The following page shows suitable circuits for trigger input and output.

Please note that input and output are not protected against over current. The output is neither protected against short circuit nor reverse voltage spikes from inductive loads.

Use the VC4018 or VC4016 cameras if you can not provide a suitable trigger input driving circuit. These cameras include the same hardware as the VCSBC4018 / -16, but opto isolation of the trigger input and output is already included.

The electrical specifications given for the trigger input and output are also valid for the

VCSBC4012.pdf – VCSBC4012 Single Board Smart Camera Operating Manual 15

Recommended driving circuit for the trigger input:

Camera side: Pin 15 Trig In

6 Programming VCSBC4012 Camera

The VCSBC4012 operating system includes some additional functions, mainly for the control of the additional interfaces. Without direct VGA output some video control functions are not implemented for this camera. This manual describes the differences between the standard VCRT 5 operating system functions and the special function library of the VCSBC40. For programming please also consult the

VCRT 5 and

VCLIB 2.0 and VCLIB 3.0 manuals (see the list of references at the beginning of this manual).

6.1 Special Software requirements for the VCSBC4012

The following table shows the minimum compatible setup options using the VCSBC4012 camera:

Code Composer Studio Version

VCRT PC Lib Version VCLIB Version VCRT Camera OS

Version: CCS 3.1 (C6000) or CCS 3.3 (C6000)

VCRT 5.27 VCLIB 3.0 VCRT 5.27

Refer to the “Support News” section, under “Support and Download” on the VC website for an overview of the latest compatible set up.

The VCRT PC lib Operation System PC library, the VCLIB Image Processing Library as well as the VCRT Camera Operation System can be downloaded from Support section of the Vision Components Website. Software manuals are located in the “Registered User Area”. This download area can be a ccessed after registration and log in on the VC Website. Software updates are available from the “Customer Area”. For access to the customer area please register your Vision Components development software for VC cameras with TI processor. Software registration can be done after logging in using the license key code shipped with each development bundle. For this please follow the “Register your Software” link under the “User Menu”.

VCSBC4012.pdf – VCSBC4012 Single Board Smart Camera Operating Manual 18

6.2 Ethernet Communication

The default camera IP address is 192.168.0.65 – as with all Ethernet cameras from VC. The IP address can be changed to a different loading a #IP file into camera memory. Refer to the “Getting Started VC Smart Cameras” guide for further details.

The camera supports DHCP server IP address allocation. In order to use DHCP allocation, the entry “DHCP” needs to be added to the #IP file as shown:

DHCP IP: 192.168.0.81 MSK: 255.255.255.0 GTW: 192.168.0.1

The camera uses the specified IP address if DHCP allocation is not successful. If no IP address is specified in the #IP file, the camera falls back to the default address:

192.168.0.65

Please use DHCP server functions to determine the IP address allocated to the camera. Most server show a list of mac addresses and corresponding IP addresses or allow to allocate fixed IP addresses to a certain mac address. Determine the mac address of the camera using the shell command “type #ID” to prior to using DHCP IP address allocation!

The “Getting Started VC Smart Cameras” and section 6.4.1 include advice on re-setting a camera with unknown or invalid IP Address.

6.3 Using FTP with the VCSBC4012

With VCRT 5.18 and higher, the use of any standard ftp client is now possible. The following server commands have been added: SYSTEM,PWD,CWD,LIST,DEL Programs have to be uploaded as “out” files into the camera flash memory. Ascii files like the autoexec or #IP files can be uploaded as “*.txt” files – the conversion into *.msf” files is not required.

6.4 Preventing Autoexec Execution / IP number reset

Preventing the execution of an Autoexec file by attempting a connection with the camera (as described in the programming tutorial) does not work, due to the increased proc essor speed. Resetting the camera using a keypad as with the VC20XX cameras is also not possible.

There are three ways of preventing the Autoexec execution and resetting the IP address:

Option 1:

1. Upload an empty autoexec/ #IP file via FTP into the camera memory, overwriting the existing file(s).

2. Hardware reset of camera.

Option 2: CPU reset with help of an Emulator.

Option 3: Resetting the camera with help of the “VCnet Recovery Tool” as described in the following

section.

VCSBC4012.pdf – VCSBC4012 Single Board Smart Camera Operating Manual 19

6.4.1 Resetting the Camera with help of the VCnet Recovery Tool

A new tool – the “Vcnet Recovery Tool” is provided for resetting the IP address of the VCSBC4012 and VC4012 cameras. Vcnet Recovery is supported from camera OS VCRT 5.21.

In order to use the VCnet Recovery tool, follow the steps below:

1. Download and install the “

Java(TM) 2 Runtime Environment, Standard Edition 1.4.XX” on

your PC (Download from

www.sun.com - > Downloads - > J2SE v 1.4.2_11 JRE ).

2. Download VCnet Recovery Tool for VC4012 and VCSBC4012 from www.vision–

comp.com -> Support ->

Customer Area Software Utilities

3. Unpack the “vcnet1.2.zip” folder a directory on your hard drive (for instance C:\ti\Util…).

4. Open the Dos command line window and change to the directory containing “vcnet.jar”.

5. Execute the following command from the DOS Window "java -jar vcnet.jar -snr 5912345" , by specifying the camera serial number as shown. This command sends vcp packets via UDP broadcast for the next 15 seconds. Sending this command resets the corresponding camera to the default IP address and bypasses Autoexec execution. Further options below.

6. Boot the corresponding camera (power on) during the next 15 seconds. During start up the camera listens 0.5 seconds for cvp pac ket s send with vcnet.jar.

7. If a valid vcp packet is received from camera an answer packet is sent (see example below). The camera continues booting in standard configuration:

Default IP address: 192.168.0.65 Mask: 255.255.255.0 Gateway: none

An autoexec in flash memory is not executed.

Example of resetting a VCSBC4012, S/N 0100151:

C:\Programme\VCnet>java -jar vcnet.jar -snr 0100151 VCnet Recovering Tool Version 1.2 - Copyright Vision Components 2005

6.5 Special VCRT functions for programming VCSBC4012 cameras

This sections explains the

specifics of programming VCSBC4012 cameras.

6.5.1 Trigger Functions

Apart form the inverse TTL logic (see section 4.2.3) and the different status register shown below, the trigger works like with the VC4XXX cameras.

Please refer to the VCRT5.pdf manual – available form the Registered User Area of the VC website.

To query the trigger input, use the following command (see demo program trigin.c):

… if (TRIGINP_PIN) print("external trigger = 1\n"); else print("external trigger = 0\n"); …

A capture can be triggered on rising edge with TRIGINP_POS() and on falling edge with TRIGINP_NEG().

The trigger output can be set to exposure controlled mode – for instance to control a light source. With TRIGOUT_EXP() combined with TRIGOUT_POS(), the trigger output is high during expo sure. TRIGOUT_EXP() combined with TRIGOUT_NEG(), the trigger output is low during exposure.

The trigger macros are also described in our programming tutorial.

The use of TRIGOUT_USR(), SET_TRIGOUT() and RES_TRIGOUT() is limited on the VCSBC4012 camera! Use only with slow applications and long shutter times (the sensor needs several

milliseconds to execute the signal change).

6.5.2 Controlling the TTL IOs on socket J2

Setting and reading the 4LVTTL inputs and outputs is done with help of the hardware registers.

The following macros are available for easier operation (see “vcrt.h”):

- Setting the 4 outputs is done with help of a 4 bit value:

#define TTL_OUT(x) *((volatile int *)FA40_LED) = x /* SBC4018 TTL output */

- For queering the TTL inputs use the following function:

#define GET_TTL_IN() (*((volatile int *)FA40_TTL) & 0x0F) /* SBC4018 TTL input */
