Serial Trigger Character

4-12 MS-3 Laser Scanner User’s Manual

4–Read Cycle/Trig-

Start and End Trigger Characters (non-delimited)

Note: Start and End serial trigger characters can be sent through host ports or aux

ports, but not the IrDA port.

Start Serial Trigger Character (non-delimited)

Note: Serial Data or Serial Data or Edge triggering mode must be enabled for

Serial Trigger Character to take effect.

Definition: A non-delimited trigger character is one that either starts or ends the

read cycle and is NOT enclosed by delimiters such as < >.

Both Start and End non-delimited characters can be defined and will

function according to the trigger event, as follows:

When defining Start and End trigger characters, the following rules apply:

•In External Edge the scanner looks only for the Start Trigger

Character and ignores any End Trigger Character that may be

defined.

•In External Level, the Start Trigger Character begins the read

cycle and End Trigger Character ends it. Note that even after a

label has been decoded and the label data transmitted, the scanner

remains in External Level trigger read cycle until a Stop character is

received.

•In Serial Data & Edge trigger mode, command, either a Start Trig-

ger Character or a hardware trigger can start an Edge trigger read

cycle.

Usage: It is useful in applications where different characters are required to

start and end a read cycle.

Definition: A single ASCII host serial trigger character that starts the read cycle

and is not enclosed by delimiters such as < and >.

Serial Cmd: <K229,start trigger character>

Default: Null (disabled)

Options: Two hex digits representing an ASCII character except <, >, XON and

XOFF.
