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.
