Product Overview:

Triggering Modes

There are five different methods that can be used to scan barcodes:

1. Software Trigger

In this mode a software command is used to trigger the ICR803. The

command structure is as follows:

[SYN] T [CR] To Trigger (Scanner LED’s will turn on and scan

barcode. After scanning the LED’s will turned

back off.)

[SYN] U [CR] To Turn off Triggering of scanner (only needed

if the scanner hasn’t scanned a barcode).

2. Button Trigger

The IC803 has an integrated button that is useful for manually triggering

the scanner.

3. Hardware Trigger

The ICR803 can be externally triggered via a hardware line (Rev C of product

and above). The external trigger is active low. When pin 1 on the modular

connector is low the ICR803 will turn on and start scanning. The ICR803 will

turn off if the trigger line goes high or if a barcode is decoded (whichever

happens first).

To Trigger Manually:

Press Button on Side
