Serial Default Commands
The following serial default commands are used to program the imaging features for your document
reader. For complete descriptions of each command, refer to the corresponding page in this manual.
For non-imaging programming commands, refer to the Barcode Manual.
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 Tag SubTag {Data} [, SubTag {Data}] [; Tag SubTag {Data}] [...] Storage
Prefix Three ASCII characters: SYN M CR (ASCII 22,77,13).
Tag A 3 character case-insensitive field that identifies the desired menu command group. For ex-
ample, 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 SubTag.
Storage A single character that specifies the storage table to which the command is applied. An ex-
clamation point (!) performs the command's operation on the device's volatile menu configu-
ration table. A period (.) performs the command's operation on the device's non-volatile menu
configuration table. Use the non-volatile table only for semi-permanent changes you want
saved through a power cycle.

Query Commands

Several special characters can be used to query the device about its settings.
^
What is the default value for the setting(s).
?
What is the device's current value for the setting(s).
*
What is the range of possible values for the setting(s). (The device's response uses a dash (-
) to indicate a continuous range of values. A pipe (|) separates items in a list of non-continuous
values.)
