Concatenating Configuration Commands

Commands can be concatenated (added together) in a single string or data block. For

example, <K145,1><K220,1><K450,1><A> enables LRC, sets End of Read

Cycle mode to New Trigger, enables Narrow Margins, and resets the data buffers

(without saving the changes for power-on).

Serial Command Status Request

To ensure that any command was received and accepted, you can send the Show

Scanner Status command: <?>.

The status of a specific serial command can be requested by entering the command

followed by a question mark. For example, send <K142?> to request the status of

Postamble. Commands <K199?>, <K399?>, <K499?>, <K899?>, and

<K699?> are used to request the status of groups of serial commands. Note that

there is no comma between the numeric and the question mark.

Entering Special Characters in Serial Commands

To enter control characters within a serial command, hold down the control key while

typing the desired character.

Example: To enter a carriage return and line feed (^M^J), enter

<K141,1,CNTL-m CNTL-j>

Entering Special Characters in Embedded Menus

Control Characters

Control characters entered on the command line are displayed in the menu as mne-

monic characters, such as: <CR><LF><NUL><NUL>.

Press SP (the space bar) once, then enter the control character by holding down the

control key and simultaneously pressing the desired character. For example to define

a line feed, press SP, then Control and J simultaneously. It is displayed as ^J on the

command line and as <LF> in the menu when the screen is refreshed.

To Define a Carriage Return as a Character

Press SP, then CR. It is displayed as ^M on the command line and as <CR> in the

menu when the screen is refreshed.

To Define a Space as a Character

Press SP twice. It is displayed as a blank space in the menu when the screen is

refreshed. While it appears that nothing has been assigned, the hex value 20 will be

sent during data transmission.

To Select NUL as the Character

Press SP, then a 0 (zero). It is displayed as <NUL> in the menu when the screen is

refreshed.
