Trigger Commands
You can activate and deactivate the scanner with serial trigger commands. First, the scanner
must be put in Manual Trigger Mode by scanning a Manual Trigger Mode barcode (page 27),
or by sending a serial menu command for triggering (page28). Once the scanner is in serial
trigger mode, the trigger is activated and deactivated by sending the following commands:
Activate:
Deactivate:
SYN T CR
SYN U CR
The scanner scans until a barcode has been read, until the deactivate command is sent, or
until the serial time-out has been reached (see Read Time-Out on page 28 for a description,
and the serial command on page 167).
Reset the Custom Defaults
If you want the custom default settings restored to your scanner, scan the Activate Custom
Defaults barcode below. This resets the scanner to the custom default settings. If there are no
custom defaults, it will reset the scanner to the factory default settings. Any settings that have
not been specified through the custom defaults will be defaulted to the factory default
settings.

Note:
The charts on the following pages list the factory default settings for each of the commands
(indicated by an asterisk (*) on the programming pages).
