• 

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. 
 
 

 

NOTE 

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 

only

 via RS232 interface by selecting another Operating Mode 

command, if you want to restore the previous state of the 
reader. 

 

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.
