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-Low transition on the I/O signal is used to
activate scanning. The signal must be deactivated (HIGH) and re-activated for subsequent scanning cycles.
The scanning cycle is terminated based on the default period of time (2 seconds), a variable period of time,
when the I/O signal is deactivated (Low-to-High), or when a bar code is scanned and transmitted.
Activate Scanning on Receipt of the <DC2> Character
A received <DC2> character initiates the scanning cycle. The scanning cycle is terminated based on the
default period of time (2 seconds), variable laser timeout selected, or when a bar code is scanned and
transmitted.
Activate/Deactivate Scanning Using D/E
A received ‘E’ character initiates the scanning cycle. The scanning cycle is terminated based on the default
period of time (2 seconds), variable laser timeout selected, or receipt of a ‘D’ or when a bar code is scanned
and transmitted.
Activate Scanning with Address
A configurable address character is used to initiate scanning. The scanning cycle is terminated based on the
default period of time (2 seconds), variable laser timeout selected, or when a bar code is scanned and
transmitted.
Common Activation Mode Features
The following configurable activation mode features are available for the IS4823 and IS4825.
Variable Laser-On Timeout (1-second Increments)
A configurable time increment selected as the scanning laser–on time.
Allow Full Laser-On Cycle
The laser stays on for a full cycle even when a bar code is scanned and transmitted.
Blinky Mode
The scanner will blink for 60 cycles (approximately 30 seconds) once the scanning cycle is activated.
