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 program
the 2020-5B. For complete descriptions and examples of each serial
programming 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:
parameterA 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 scanner (with the base connected to
host): :3820: The default factory setting for an 3820 scanner is
3820. This setting is changed by using 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
scanner once they are linked, changes are typically done to the base and
not to the 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.
