Chapter 5 - Reader-Specific Platform Specifications BRI Commands The following BRI commands are not implemented in the ITRFxxx01 BRI: • TRIGGER • TRIGGERREADY • TRIGGERQUEUE In this example, the WHERE expression is evaluated exactly as described in "Using AND/OR Logic in Data Conditions" on page 30: READ INT(18) WHERE INT(19)=1 OR INT(20)=1 AND INT(21)=3 However, if you change the order of the expression, the resulting tags selected are evaluated as if parentheses were used: READ INT(18) WHERE INT(20)=1 AND INT(21)=3 OR INT(19)=1 Since an OR follows an AND, the expression is evaluated using parentheses: READ INT(18) WHERE ( INT(20)=1 AND INT(21) ) OR INT(19)=1 Implied parentheses are applied any time an OR keyword is followed by an AND keyword. EVENT Responses The ITRFxxx01 reader does not support the event responses, as described in "Understanding Error and Success Responses" on page 109. Phillips V1.19 TAG Type The ITRFxxx01 reader does not support the Phillips V1.19 tag type, as described in "TAGTYPE" on page 96. Readers That Contain the IM5 Module RFID readers that contains the IM5 module deviate from the BRI specification as described in this section. For a complete list of RFID readers that contain the IM5 module, see your Intermec representative. Buffer Sizes Be aware of these buffer size limits on readers that contain the IM5 module and architecture older than IF61 v2.00: • Maximum command line buffer size is 255 characters including expanded macros. • Maximum macro buffer size is 255 characters. • Maximum macro name size is 32 characters. • Maximum [LITERAL] lengths are 255 characters. • Maximum length for HEX and STRING data type definitions are 104 characters. 120 Basic Reader Interface Programmer Reference Manual
