Serial Programming Commands
The serial programming commands can be used in place of the programming
bar codes. Both the serial commands and the programming bar codes will pro-
gram the 2020. For complete descriptions and examples of each serial pro-
gramming command, refer to the corresponding programming bar code in this
manual.
The device must be set to an RS-232 interface (see page 1-21). 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): :3820/3820i: The default factory setting for a 3820/
3820i image scanner is 3820/3820i. This setting is changed by us-
ing the BT_NAM command, which accepts 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 the
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.
