Trigger Commands
You can activate and deactivate the image scanner with serial trigger com-
mands. First, the image scanner must be put in Manual/Serial Trigger Mode
either by scanning the Manual/Serial Trigger Mode barcode (
page 4-4 ), or by
sending the Manual/Serial Menu Command ( page 12-10 ). Once the image
scanner 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 image 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 (Serial Trigger Mode)" on page 4-4 for a description, and the serial
command on
page 12-10 ).
