5. FUNCTIONS
The SCB-1 can be controlled through a key-matrix or via RS-232 (SCOTI).
With the WolfVision SCB-1 Interface board the basic control functions can be done for
evaluation-purposes.
5.1 ZOOM
The SCB-1 uses an 12x zoom lens as well as a 2x digital zoom.
Optical 12x, f=5.8 to 69.6 mm (F=2.8 to 3.0)
The digital zoom is automatically switched ON at the tele end of 12x optical zoom range,
with progressive effect from 1 to 2, giving a total maximum 24x zoom ratio. Digital zoom
increases the picture element size and reduces the resolution.
Extended control of zoom:
•Direct zoom position
•Get current zoom position
•Zoom speed selection (15 speeds)
•Digital zoom can switched ON/OFF
•OSD-message or stop of zooming when digital-zoom is entered (selectable)
5.2 FOCUS
The minimum focus distance (MOD) is below 50mm at optical wide end and below 500mm
at optical tele end, and is independent of digital zoom. If shorter distance are necessary, a high
quality close up lens is available (see optional accessories). An Auto-Focus (AF) function is
also available (enabled by default).
Extended control of focus:
•Direct focus position
•Get current focus position
•Manual Focus speed selection (15 speeds)
•Focus can switched to Auto-Focus (permanent), One Push Auto- or Manual Focus
•Auto-Focus region can be switched between center (AF measures in the center area of
the image) and large (measure the complete image)
•Focus Priority: "Auto" - activates Auto-Focus by pressing a ZOOM-key
5.3 IRIS
After power-on AI, ASC and AGC are enabled by default.
Extended control of Iris:
•Direct Iris position
•Get current Iris position
•Manual Iris speed selection (2 speeds)
•Iris Priority: "Auto" - activates Automatic Exposure Mode by pressing a ZOOM-key
•Automatic / manual: Iris, Shutter and Gain

SCB-1 Functions
R

Auto Iris (AI)
The iris changes automatically according to the brightness of the subject. If ASC and / or
AGC are enabled, they change also automatically if necessary.
Auto Shutter Control (ASC)
If enabled, the shutter virtually extends the iris-range if the iris is closed as much as possible.
If disabled, the shutter can be set from 1 (very short exposure time) to 1188 (maximum
exposure time).
Auto Gain Control (AGC)
If enabled, the gain virtually extends the iris-range if the iris is fully opened. If the AGC is
disabled, it can be set to any gain-value from 0dB to 32dB.
Manual Iris
The iris can be opened or closed manually. If ASC or AGC are enabled, they extend the
possible adjustment-range. The Iris can also be set directly between 000 to FFF (in
hexadecimal), the higher the value, the brighter the picture.
Exposure Compensation
Exposure compensation allows you to fine-adjust the image-brightness in steps from -10
(darker) to +10 (brighter) in the auto-iris-mode.
5.4 White Balance
Each time the lighting conditions change, adjust the white balance so that the optimal color
reproduction is obtained.
•ATW: Auto Tracking White Balance
The WB is automatically adjusted as the color temperature changes.
•One Push WB: One Push auto tracking White Balance (store values in Manual WB)
(OWB) Press the keys "Shift" + "Freeze" simultaneously, the message "White
Balance" appears on the screen while the white level is being
adjusted. When the adjustment is done, the message "White OK"
appears on the screen. The adjusted level is automatically stored in
the memory, even if the camera's power is turned off.
•Manual WB: Manual control of R and B gain (-120 to +120 each)

Functions SCB-1

White balance adjustment errors
If the white balance adjustment is not successful, an error message appears on the screen. If
this happens, take the necessary measures.
Error message Description and remedy
White: Too Bright! The video signal level is too high. Take one or more of the following
measures and then perform the OWB again:
•Remove any brightly illuminated objects
•Decrease the illumination
•Close the iris opening
•Decrease the video gain
White: Too Dark! The video signal level is too low. Take one or more of the following
measures and then perform the OWB again:
•Increase the illumination
•Widen the iris opening
•Increase the video gain
White: Out of Range! Place a white sheet of paper and perform the OWB again.
5.5 User-OSD (On Screen Display)
Beside the on-screen-menu and other camera-messages the SCB-1 also allows the user to
display his own messages. If the User-OSD is enabled, the SCB-1 displays no own messages,
the menu is not selectable.
The camera can display 15 lines of up to 30 characters. The top line can be displayed in the
double character height.
Following colors can be set: black, red, green, yellow, blue, purple, cyan and white.
The color can be set for each line.
5.6 Image Memory
The SCB-1 has an image memory from which a stored image can be output as a still image.
You can store four images plus one frozen image in the memory.
Press one of the MEMORY-keys (1 - 4) for 2 seconds to store a image into memory. To recall
press the MEMORY-key quickly.
To capture the image into memory, use the FREEZE-key. The captured image is output.
5.7 Preset Function
The SCB-1 offer the possibility of programming 9 presets plus 1 power-on preset for the
functions Zoom, Focus, Iris, Positive/Negative and Black/White.
Preset 1 to 4 can be stored and recalled be the 4 PRESET-keys on the SCB-1 Interface board.
Press one of the PRESET-keys (1 - 4) for 2 seconds to store preset into memory. To recall
press the PRESET-key quickly. The presets 5 to 9 can only be controlled via SCOTI (RS-
232).

9. HANDLING PRECAUTIONS
9.1 Handling
Avoid spilling water or any liquids on to the camera. Do not allow metallic objects to fall
inside the body or contact the electronic boards.
9.2 Operation and storage locations
Avoid operation or storing the camera in the following locations:
•Extremely hot or cold places (operation temperature: 0°C to +40°C)
•In direct sunlight for long periods, or close to heating equipment (e.g., near heaters)
•Places subject to excessive dust or oil or gas
•Places where there are strong electromagnetic waves or magnetism, the picture could
be distorted.
•Places where there are radiation, this could damage the CCD and other components
and cause a malfunction
•Places where the camera would be subject to strong vibrations. This could damage
components and degrade the picture.
9.3 Cleaning
Remove dust or dirt on the surface of the front lens with air pressure.
9.4 Other
•Do not apply excessive force to the printed circuit boards.
•Do not apply excessive voltage, use only the specific voltage
•Prevent static electricity; wear a wrist band when touching the camera. Use a antistatic
bag to package the camera.
•Repack the camera as it was originally for transport.
•Do not block air circulation around the camera to prevent internal heat buildup.
9.5 Software
Turn on the camera first and then start the camera control software on your PC. The Camera
Control Software (for Microsoft Windows 95, 98, ME, 2000 and XP) operates the SCB-1 via
SCOTI (RS-232).

10. COMMAND LIST
10.1Specification of SCOTI (SCB Operating & Transfer Interface)
Overview
The SCB-1 can be controlled via a RS-232-interface. The used protocol is called SCOTI (for
SCB operating and transfer interface).
The baud rate is set to 9600 (8, n, 1, no handshaking) out of the factory. It can be changed to
19200, 38400, 57600, 115200, 230400, 460800 or 921600. The high transfer-rates are useful
if you want to transfer images via RS-232 (not possible with 9600). Please note that baud
rates above 115200 are not supported by all PC and may require special drivers and/or
hardware. We can recommend you serial-port-cards that support 921600 baud. You can get
the latest Camera Control software (see page 15) from
http://www.wolfvision.com/wolf/camera_control.exe. This software uses the SCOTI-protocol
and demonstrates all possibilities and can be used for image-transfers.
The communication is packet-oriented: The host sends a packet and the SCB replies to it with
"OK" or an error (e.g. if the checksum was incorrect). A new packet from the host can be sent
after the reply from the previous packet was received (or a timeout occurred).
Change baud rate
To change the baud rate, start the WolfVision Camera Control software. Set the new baud rate
in the "Extras"-menu. To permanently store the new setting, select "Memorize Current Baud
rate".
If the Camera Control software is not available, use the RS-232 commands on page 23.
Following baud rates are supported since firmware v1.03a and Camera Control software v1.3:
19200 baud/s
38400 baud/s
57600 baud/s

SCB-1 Command List
R

Packet-Format
Short-Packet-Format: For short packets (up to 15 Byte Data):
00hex Len+F0hex Data[1] Data[2]... Data[Len] Checksum
Long-Packet-Format: For long packets (up to 61439 Byte Data):
00hex Len H Len L Len-Checksum Data[1]... Data[Len] Data-Checksum
The long-packet-format-data can also be used for short packets (below 15 bytes of data).
(However, only one of the two possible formats will be used in this document.) The long
packet-format is mainly used for the "OSD Write Line"-command and for image transfers.
Len H and Len L are the High- and Low-Byte of the 16 bit Length. The High-Byte is not
allowed to get F0hex or higher, as this would indicate the short-packet-format. In the short-
packet-format, F0hex is added to the length, so F1hex is for 1 byte length, F2hex for 2 byte,
etc.
The checksum is the ones-complement (bit-wise NOT) of the sum of all length- and data-
bytes (truncated to 8 bit).
The length-checksum is the ones-complement (bit-wise NOT) of the sum of both length-bytes
(truncated to 8 bit).
The data-checksum is the ones-complement (bit-wise NOT) of the sum of all data-bytes
(truncated to 8 bit).
The shortest possible packet has a length of 4 Bytes (using the short-packet-format): 1 Byte
Header, 1 Byte Length, 1 Byte Data and 1 Byte Checksum. For example, if Data is 01hex:
00hex F1hex 01hex 0Dhex
Header Length Data Checksum
(F1hex+01hex=F2hex,
Ones-Complement=0Dhex)
Following message in the long-packet-format would have the same effect:
00hex 00hex 01hex FEhex 01hex FEhex
Header Length H Length L Check Len Data Checksum Data
(00hex+01hex=01hex, (01hex=01hex,
Ones-Complement=FEhex) Ones-Complement=FEhex)
The host and the camera should both ignore all the data that they receive if a header is not
detected (however, the camera will respond to 76hex with a version-string) If the camera
detects a checksum-error, it will reply with a checksum-error-packet and the host should
resend the packet. If e.g. the header from the host is corrupted, the camera will not detect the
header and will not respond to the packet. The host should then time-out and resends the
packet. If a false header is detected (e.g. a Data-Byte is 00hex) a checksum-error will be
generated. If the camera receives the start of a packet, but not enough data, it will timeout
after 1 second and send a time-out-error-packet.

Command List SCB-1
R
16
Version Check
A special command, which is the only command that does not use the packet-format is 76hex
(ASCII 'v'). If the camera receives this command, it will respond with "SCB-1
Vx.xxx"+CR+LF. This command can be used for easy communication-check with a terminal
program and is also included for compatibility with other WolfVision Products.

Commands of Camera, Future
The SCOTI protocols of all WolfVision cameras (stand alone) are almost the same.
Only some commands more or less are supported on other camera-types due to the different
technologies.
In the future (at higher firmware-versions) further commands may be added which are not
supported yet (listed commands are available with v1.03a).
