Serial Command Format

MS-820 Industrial Bar Code Scanner User’s Manual A-15

Appendices

Appendix E — Serial Command Format

Serial commands are of two types: utility and configuration.

Rules that apply to both utility and configuration commands

• A less than < and greater than > characters enclose the commands.

• Commands and data are “case sensitive.” That is, characters must be entered as

upper or lower case, as specified.

Serial Utility Commands

These are sent during operations and are not followed by a <A> or <Z>. See Tab le

11-1, “Summary of Utility Serial Commands,” on page 11-3.

Serial Configuration “K” Commands

See Appendix E — “Serial Command Format” on page A-15.

These begin with a single K character followed by a single character, data fields, and

an initializing command, as follows:

<Kparameterdata,data,...etc.><initializing command>

An initializing command <A> or <Z> always follows the command. A <Z> initializes

the scanner’s memory and saves for power-on; an <A> initializes the scanner’s mem-

ory but does not save for power-on.

For example, to enable UPC and save the change for power-on, send <K1><Z>.

To ch ang e Baud Rate and reset without saving changes for power-on, send

<Ka3><A>.

Serial Configuration Command Conventions

• All data fields (except the last) must be followed by a comma (without a space).

• The following characters cannot be used: , < > NUL.

• All fields preceding a modified field must be included.

• If there is no change in preceding fields, then commas alone can be entered in

these fields. For example, if only the last field in the following command is chang-

ing, <Ka4,1,0,0> can be entered as <Ka,,,0>.

• All fields following a modified field can be omitted. For example, to change Baud

Rate, send <Ka3>.
