10.1 Online commands
10.1.1 Overview of commands and parameters
Online commands can be used to send commands directly to the code reader for control and configuration.
For this, the code reader has to be connected to a computer (host) via the serial interface or the Ethernet
interface (see chapter 8.3.4 "Ethernet host communication").
Online commands offer the following options for controlling and configuring the code reader:
• Control/decode the reading gate
• Read/write/copy parameters
• Carry out an automatic configuration
• Teach-in/set reference codes
• Call up error messages
• Query statistical device information
• Perform a software RESET and re-initialize the code reader
Syntax
Online commands consist of one or two ASCII characters followed by command parameters.
No separation characters may be entered between the command and the command parameter(s). Both
small and capitalized letters can be used.
Example:
Notation
Commands, parameters and returned data are enclosed between single quotation marks in the text of
