Keywords Reserved for Command Parameters
The BRI command syntax defines several reserved keywords to express parameters
for each of the BRI commands. The following table lists the reserved keywords,
special characters, and their meaning.
SET
Creates, lists, and deletes macros.
SWVER
Returns the current firmware version.
TRIGGER or TRIG
Defines a trigger based on time or a general purpose I/O
signal.
TRIGGERQ, TRIGQ,
TRIGQUEUE, or
TRIGGERQUEUE
Checks the trigger event queue for events that are currently
stored.
TRIGGERREADY,
TRGRDY, TRIGREADY, or
TRIGGERRDY
Transitions the reader event queue to the READY state;
enables the asynchronous reporting of the oldest trigger event
in the reader event queue.
TRIGGERWAIT, TRIGW,
TRIGWAIT, or TRIGGERW
This command is no longer available. Use TRIGGERREADY
instead.
VERSION or VER
Displays the reader firmware version.
W, WR, or WRITE
Writes information to one or more tags.
WRITEGPO, WRGPO,
WRGPIO, or WRITEGPIO
Writes the general purpose output values.
Keywords Reserved for BRI Commands (continued)
Keyword
Description
Note:
The TRIGGERWAIT command is no longer available. Because the term “wait”
is confusing, the TRIGGERWAIT command has been replaced by the
TRIGGERREADY command. The TRIGGERWAIT command remains in the BRI for
backward compatibility. Intermec recommends that you use TRIGGERREADY.
Keywords Reserved for Command Parameters
Keyword or
Special Character
Description
!=
Not equal to.
\n
Defines a line feed value.
\r

\xxx
Defines an octal character.
“ ”
Double quotes are the default characters to define simple text string
values.
<
Less than.
=
Equal to.
>
Greater than.
ACTION
When used in defining a TRIGGER, this keyword can be used to have
the trigger execute a command based on a defined macro.
AND
Performs a logical AND operation of statements in a WHERE clause.
ANTENNA or
ANT
Specifies that the command should return the antenna used during the
READ or WRITE command.
