N4680 2D Decoded Scan Engine User Guide 185
Trigger Commands
You can activate and deactivate the scan engine with serial trigger commands.
First, the scan engine must be put in Manual Trigger Mode by scanning a Manual
Trigger Mode bar code (page 32), or by sending a serial menu command for trig-
gering (page 191). Once the scan engine is in serial trigger mode, the trigger is
activated and deactivated by sending the following commands:
Activate: SYN T CR
Deactivate: SYN U CR
The scan engine scans until a bar code has been read, until the deactivate com-
mand is sent, or until the serial time-out has been reached (see "Read Time-Out" on
page 3-34 for a description, and the serial command on page 191).
Setting the Custom Defaults
You can set the custom defaults by sending serial commands. Use the following
concatenated command format to store custom defaults in your product:
MNUCDF;DEFOVR;<CMD1>;<CMD2>; ... <CMDX>;MNUCDS@
The custom defaults are not applied immediately, to activate send the Activate
Defaults command or read the DEFALT bar code below.
Resetting the Custom Defaults
If you want the custom default settings restored to your scan engine, scan the Acti-
vate Custom Defaults bar code below. This resets the scan engine to the custom
default settings. If there are no custom defaults, it will reset the scan engine to the
factory default settings. Any settings that have not been specified through the cus-
tom defaults will be defaulted to the factory default settings.
The charts on the following pages list the factory default settings for each of the
commands (indicated by an asterisk (*) on the programming pages).
Note: To remove custom defaults, see Resetting the Factory Defaults on page 179.
