This chapter presents information on the operational modes for the 
Sabre 1555 RFID & Bar Code Reader.
The Sabre 1555 uses two operational modes to set up and control its options: 
autonomous and interactive. The autonomous mode is discussed in this chapter. The 
interactive mode is discussed in detail in Chapter 4, “Interactive Programming Mode,” 
of this guide.
Autonomous Mode
You can choose certain setup options that control the Sabre 1555 by using the 
Autonomous Mode features. You cannot use Autonomous Mode to modify all the 
setup parameters of the Sabre 1555 (you must use either the EasySet configuration 
software or setup mode commands (SMC) to access all of the setup options). 
Table 3-1 lists each Autonomous Mode menu display, its associated option, and a 
description of that feature/function.
The configurable RFID functions include Tag Identify, Tag Read, Tag Write and Tag 
Filter. The Tag Read function allows the user to access information previously 
programmed into the RFID tag storage locations, and then transmit that data to the 
host system. The Tag Write function allows the user to program the RFID tag with 
desired information. Tag Identify enables the user to determine how many tags are in 
the read area of the 1555, and their unique tag IDs are read and can be transmitted to 
the host system. At any given interrogation point in the customer’s RFID tracking 
process, any single function or a combination of two or three functions may need to be 
employed. Additionally, the customer may need to employ a “Filter” or “Mask” with 
the primary RFID function in order to get the desired result. The Filter instructs the 
1555 to locate only a desired subset from all the tags in the read area of the 1555, and 
the Read, Write or Identify function will be performed only with that select subset.  
The filter or mask functions are primarily used to speed the process of identification of 
the select tags targeted for interaction with the reader. This speeds the transaction 
because the filter function effectively eliminates tags that contain data not matching 
the filter criteria included in the request from the reader. This takes advantage of a 
function that has been specifically designed into the Intellitag® tag ASIC, which 
inhibits the tag from participating in the tag sorting process unless data in the tag 
matches the filter criteria included in the request from the reader.
