17 Descriptions of IS4823 and IS4825 Operating Modes Activation Modes The following activation modes initiate the engine’s laser and motor drive circuitry for bar code scanning. Activate Scanning with the External Trigger (Default). An external I/O pin is used to enable the scanning cycle. A High-to...

18 Transmit “NO READ” Message on Laser Timeout If the scanning cycle terminates without scanning a bar code during the cycle, a “NO READ” message is transmitted with the termination of the scanning cycle. Activate the LED During the “NO READ” Transmission The LED is activated with the “NO READ” mess...

19 Serial Configuration Mode The IS4823/IS4825 can be configured by scanning configuration bar codes † or by serial commands sent from the host device. With serial configuration, each command sent to the engine is the ASCII representation of each numeral in the configuration bar code (see Figure 15 ...

20 Example 2: The following sample illustrates the serial command sequence for configuring the engine for the factory default settings, disabling Code 128 scanning, and adding a “G” as a configurable prefix. Commands for features that require sequences of multiple bar codes for activation (i.e. pref...
