Chapter 4 - BRI Commands BRI Commands The BRI commands and responses are defined in this section. These examples follow these formatting conventions: • Values in brackets [ ] are optional parameters. • Values in angle brackets < > are required parameters. Note: Not all BRI commands are supported by all Intermec RFID readers, and specific ranges for commands and attributes may differ from product to product depending on hardware options. For help, see "Reader-Specific Platform Specifications" on page 118," and the documentation for your Intermec RFID reader.

Basic Reader Interface Programmer Reference Manual
BRI Commands
The BRI commands and responses are defined in this section. These examples
follow these formatting conventions:
•
Values in brackets [ ] are optional parameters.
•
Values in angle brackets < > are required parameters.
For BRI extensions and commands that are specific to:
•
NXP tags, see
“BRI Extensions for NXP Tags” on page 74
.
•
Fujitsu tags, see
“BRI Extensions for Fujitsu Tags” on page 76
.
•
Impinj Monza 4 tags, see
“BRI Extensions for Impinj Monza 4 Tags” on
page 80
.
•
EM Microelectronics tags, see
“BRI Extensions for EM Microelectronics
Tags” on page 81
.
ATTRIBUTE
Purpose:
This command changes or reads the reader attributes.
Command Shortcut:
ATTRIB
Changing the Reader Attributes
For BRI Applications
Using TCP:
If your BRI application communicates with the reader over a TCP connection, you
cannot use the ATTRIBUTE command to modify the BAUD, CHKSUM, ECHO, or
FIELDSEP attributes from their default settings. For details, see
“BRI TCP
Applications” on page 3
.
Syntax:
ATTRIBUTE [<ATTRIBUTE NAME>=[<VALUE>]]*
Parameters:
<ATTRIBUTE NAME> = This parameter specifies the attribute to change in the
reader. For a complete description of the reader attributes, see
“Understanding the
<ATTRIBUTE NAME> Parameter” on page 86
.
<VALUE> = This parameter specifies the new value for the attribute:
•
For “tries” attributes (such as RDTRIES), the value corresponds to a count.
•
For “timeout” attributes (such as IDTIMEOUT), the value corresponds to a time
period (units of milliseconds).
Examples:
These examples demonstrate how to use the ATTRIBUTE command to change
reader attributes.
Example 1:
This example returns the current settings for all attributes:
ATTRIBUTE<CRLF>
Note:
Not all BRI commands are supported by all Intermec RFID readers, and
specific ranges for commands and attributes may differ from product to product
depending on hardware options. For help, see
“Reader-Specific Platform
Specifications” on page 118
,” and the documentation for your Intermec RFID
reader.
