Introduction
1 INTRODUCTION
The VB8 compact CCD reader is the perfect solution for many OEM applications. It contains a built-in decoder mix of technical characteristics it is perfect for integration into custom equipment, setting a new standard in this product class.
This Reference Manual provides connection diagrams, default parameter listing, complete application parameter settings, specific technical features and reading diagrams.
Configuration for RS232 Interface User's
The easiest way to configure VB8 is by using the Configurations utility program installed from the CD included with this manual. It provides a user-friendly graphic interface that sends the command strings to the VB8 and Help On-Line to explain configuration parameters.
This manual contains the complete set of command strings for VB8 configuration. These strings must be sent via the RS232 interface using a terminal emulator such as HyperTerminal, or with the WinHost Terminal. Configurations can also be sent as batch files.
Refer to paragraph 3.2 for configuration procedures.
Configuration for Wedge Interface User's
For Wedge Interface User's, configuration can be accomplished either by reading the Return to RS232 Interface Interface, or by printing the command strings as a barcode label (or labels) and then reading them with the VB8. The symbology must be Code 128 subset B.
Reference notes describing the operation of the more complex parameters are given in chapter 4.

2.3 POSITIONING
The VB8 scanner is able to decode barcode labels at a variety of angles, however significant angular distortion may degrade reading performance.
When mounting the VB8 take into consideration these three ideal label position angles: Pitch 0°, Skew 10° to 30° and Tilt 0°. Follow the suggestions for the best orientation:
The Pitch angle is represented by the value P in Figure 23. Position the reader in order to minimize the Pitch angle.
Figure 23 - Pitch Angle
The Skew angle is represented by the value S in Figure 24. Position the reader to assure at least 10° for the Skew angle. This avoids direct light reflection.

3.2 VB8 CONFIGURATION
VB8 is factory set for RS232 Interface applications. The easiest way to configure VB8 is by using the Configuration utility program installed from the CD
included with this manual. Otherwise you can configure the scanner using this manual as follows:
To use this manual for configuration:
1) Connect your VB8 to a PC RS232 port according to the information in
chapter 2. Set the PC serial port to the VB8 default RS232 communication parameters.
2) Using a Terminal Emulation Program send the Restore Default string to the reader using the syntax described on the next page.
3) Send all the necessary command strings according to your application's requirements.
The WEDGE or PEN Emulation interface selections must be sent last since they will cause the reader to no longer accept RS232
CAUTION
If working with the Wedge or Pen emulation interfaces, it is possible to return to the RS232 connection by reading the code given below:

4.1 RS232 PARAMETERS
4.1.1 Handshaking
Hardware handshaking: (RTS/CTS)
The RTS line is activated by the decoder before transmitting a character. Transmission is possible only if the CTS line (controlled by the Host) is active.

Figure 31 - RTS/CTS handshaking
Software handshaking: (XON/XOFF)
During transmission, if the Host sends the XOFF character (13 Hex), the decoder interrupts the transmission with a maximum delay of one character and only resumes when the XON character (11 Hex) is received.

4.1.2 ACK/NACK from Host Protocol
This parameter sets a transmission protocol in which the Host responds to the reader after every code transmitted. The Host sends an ACK character (06 HEX) in the case of good reception or the NACK character (15 HEX) requesting re-transmission, in the case of bad reception.

4.1.3 FIFO
This parameter determines whether data (barcodes) are buffered on a First In First Out basis allowing faster data collection in certain cases for example when using slow baud rates and/or hardware handshaking.
If the FIFO buffering is enabled, codes are collected and sent out on the serial line in the order of acquisition. About 800 characters can be collected (buffer full), after which the reader signals an error and discards any further codes until the transmission is restored.
If the FIFO buffering is disabled, each code must be transmitted before another one can be read.
4.1.4 RX Timeout
When the RS232 interface is selected, the Host can be used to configure the device by sending it command strings (see chapter 3).
This parameter can be used to automatically end data reception from the Host after the specified period of time.
If no character is received from the Host, after the timeout expires, any incomplete string (any string not terminated by <CR>) is flushed from the device buffer.

4.2 PEN PARAMETERS
4.2.1 Minimum Output Pulse
This parameter sets the duration of the output pulse corresponding to the narrowest element in the barcode. In this way the code resolution is controlled by the signal sent to the decoder, independently of the physical resolution of the code read.
µ
The shortest pulse (200 therefore a shorter transfer speed to the decoder (for decoders able to work on high resolution codes). Likewise, longer pulses correspond to low resolution code emulation and therefore a longer transfer time to the decoder.
s) corresponds to a high resolution code emulation and
4.2.2 Overflow
This parameter generates a white space before the first bar and after the last bar of the code. The selections are as follows:
narrow = space 10 times the minimum output pulse. medium = space 20 times the minimum output pulse. wide = space 30 times the minimum output pulse.

SET CUSTOM EXTENDED HEADER/TERMINATOR KEYS
The extended Header/Terminator keys for Wedge Interface customized by defining them through a simple keyboard setting procedure.
For example, the Numeric Keypad keys can be set for use as Headers or Terminators by substituting the default extended keys using this procedure.
The type of computer or terminal must be selected before activating the keyboard setting command.
Press and release a key to set it.
Some characters may require more than one key pressed simultaneously during normal use (refer to the manual of your PC or terminal for keyboard use). The exact sequence must be indicated to the reader in this case pressing and releasing the different keys.
Example:
If one has to press the "Shift" and "4" keys simultaneously on the keyboard to transmit the character "$" to the video, to set the "$", press and release "Shift" then press and release "4".
Each pressed and released key must generate an acoustic signal on the reader, otherwise repress the key. Never press more than one key at the same time, even if this corresponds to the normal use of your keyboard.
Press "Backspace" to correct a wrong key entry. In this case the reader emits 2 beeps.
Note: "CAPS LOCK" and "NUM LOCK" must be off before starting the keyboard setting procedure. "SHIFT" must be repressed for each character and cannot be substituted by "CAPS LOCK".

4.4.1 Sleep State
µ
This mode allows the consumption. This command is only valid when On-Line is selected.
Before entering Sleep mode, the following are verified:
no commands coming from Host
no data being transmitted to Host
Enter Sleep Timeout ended
To exit Sleep mode press the trigger.
Enabling the Sleep state implements Standby mode for CCD devices.
P in the reader to enter a “Sleep” state for minimum power
4.4.2 Enter Sleep Timeout
For readers that have the Sleep state enabled, this timeout determines when the reader will enter this state.
4.4.3 Standby
If this command is enabled, part of the CCD circuitry shuts down (Standby), in order to optimize low power consumption when not reading. When the trigger is pressed this circuitry powers up. This mode causes a minor delay of about 100 ms before the reader is ready.
4.5 READING PARAMETERS
4.5.1 Operating Modes
This group of parameters allows setting different reading modes:
ON-LINE: the VB8 reader is connected to an external Presence Sensor using EXT TRIG+ and EXT TRIG- inputs. During the active phase of the presence sensor, the VB8 tries to acquire and correctly decode the code. If the operation is successful, the barcode characters are transmitted on the serial interface in the format defined by the current configuration. Otherwise a No Read message is sent: it is fixed as the CAN symbol;

Preferences
AUTOMATIC: the VB8 reader does not require connections with external presence sensors in this operating mode. In this mode the illuminator is always ON and VB8 is continuously scanning. The reading phase is enabled when a barcode enters the reading zone of the camera and is terminated after a fixed number of scans without a code. The next reading phase will begin when a code enters the reading zone again. The number of scans without a code is an optimized value for the CCD camera in order to improve code identification in the reading zone. Code transmission occurs as in the other operating modes but in case of No Read condition there is no transmission on the serial port.
SERIAL ON-LINE: the reading phase starts when the Serial Start Character is received on the serial interface and ends when the code is read or a Serial Stop Character is received. If decoding is correct, the data is transmitted on the serial port as defined by the configuration. Otherwise a No Read message is sent: it is fixed as the CAN symbol. The Start and Stop characters are also fixed:
Serial START: STX Serial STOP: ETX
TEST MODE: test mode allows verifying the reader position and the associated reading features. The code is continuously read when in this mode. After 400 ms, the values relative to an internal counter and the decoded code are displayed and transmitted on the serial interface. The counter reports a statistical calculation which consists of a good reading percentage of the total acquisitions.
The following message could be displayed:
Counter value Code 090% 12345ABC
If the CCD reader cannot decode a label, the following message will be displayed:
0%.
Only one barcode label must be read for each reading cycle.
Since Test Mode is basically a diagnostic mode, it can only be enabled at run time and not saved to a non-volatile memory. For the same reason, this operating mode must be disabled
NOTE
only via RS232 interface by selecting another Operating Mode

4.5.2 Reads per Cycle
In general, a reading cycle corresponds to the Phase ON / Phase OFF times of a device. The resulting effects of this parameter on code reading depend on other related configuration conditions. Here are the definitions of Phase ON and Phase OFF times.
When one read per cycle is selected, the device decodes only one code during the Phase ON period and immediately turns to the Phase OFF another code when the next Phase ON time occurs.
In multiple reads per cycle, the Phase ON period is extended so that the device can continue decoding codes until an OFF event occurs.
. It is only possible to read
4.6 DECODING PARAMETERS
These parameters are intended to enhance the decoding capability of the reader for particular applications. Used incorrectly, they can degrade the reading performance or increase the possibility of a
CAUTION
decoding error.
4.6.1 Ink-Spread
The ink-spread parameter allows the decoding of codes which are not perfectly printed because the page texture tends to absorb the ink.
4.6.2 Overflow Control
The overflow control parameter can be disabled when decoding codes printed on small surfaces, which don’t allow the use of an overflow space.
This command does not effect code families 2/5, Code 128 and Code 93.
This command is forced (enabled) when PDF417 codes are enabled.
4.6.3 Interdigit Control
The interdigit control parameter verifies the interdigit spacing for code families Code 39 and Codabar.
