Serial Programming Commands
The serial programming commands can be used in place of the programming
barcodes. Both the serial commands and the programming barcodes will
program the image scanner. For complete descriptions and examples of each
serial programming command, refer to the corresponding programming barcode
in this manual.
The device must be set to an RS-232 interface (see page 2-2 ). The following
commands can be sent via a PC COM port using terminal emulation software.
Conventions
The following conventions are used for menu and query command descriptions:
parameter A label representing the actual value you should send as part of a
command.
[ option] An optional part of a command.
{Data} Alternatives in a command.
bold Names of menus, menu commands, buttons, dialog boxes, and
windows that appear on the screen.
Menu Command Syntax
Menu commands have the following syntax (spaces have been used for clarity
only):
Prefix [:Name:] Tag SubTag {Data} [, SubTag {Data}] [; Tag SubTag {Data}] […]
Storage
Prefix Three ASCII characters: SYN M CR (ASCII 22,77,13).
:Name: To send information to the image scanner (with the base connect-
ed to host), use
: 4820 : or : 4820i : The default factory setting for a
4820 image scanner is 4820, and 4820i for a 4820i image scanner.
This setting is changed by using the BT_NAM command, which ac-
cepts alphanumeric values. If the name is not known, a wildcard
(*) can be used :*:.
Note: Since the base stores all work group settings and transfers to them to
image scanner once they are linked, changes are typically done to the
base and not to the image scanner.
Tag A 3 character case-insensitive field that identifies the desired menu
command group. For example, all RS-232 configuration settings
are identified with a Tag of
232 .
SubTag A 3 character case-insensitive field that identifies the desired menu
command within the tag group. For example, the SubTag for the
RS-232 baud rate is
BAD .
Data The new value for a menu setting, identified by the Tag and Sub-
Tag.
