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.

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.

4.2.3 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 5:
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.
5The electrical specifications given for the trigger input and output are also valid for the
remainingLVTTL IOs.

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:

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 processor 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.

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 packets 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

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 exposure.
TRIGOUT_EXP() combined with TRIGOUT_NEG(), the trigger output is low during exposure.
