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 IT3800/3900. 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 1-8 ). 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 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 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.
Storage A single character that specifies the storage table to which the
command is applied. An exclamation point (!) performs the com-
mand’s operation on the device’s volatile menu configuration 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. (The non-volatile table allows only a limited number of
writes.)
