Symbol
ST When the ID Controller receives a command, it communicates with the Tag and then
returns a response.
SA When the ID Controller receives a command, it waits to detect a Tag in the Antenna's com-
munication area. When the ID Controller detects a Tag, it communicates with the Tag and
then returns a response.
SI When the ID Controller receives a command, it communicates with the Tag on the rising
edge of the TRG external input and then returns a response.
RA The ID Controller repeats the operation for a single auto designation (SA) as Tags enter
the Antenna's communications area. The ID Controller communicates with each Tag in the
communications area only once even if the Tag remains in the area.
RI The ID Controller repeats the operation for a single input trigger designation (SI).
PA The ID Controller performs the operation for a single auto designation (SA) and then
returns a response when it receives a POLLING QUERY (PC) command.
PI The ID Controller performs the operation for a single input trigger designation (SI) and then
returns a response when it receives a POLLING QUERY (PC) command.
FT When the ID Controller receives a command, it returns a response. After communicating,
all further operations with that Tag are prohibited. The ID Controller communicates with
only one operable Tag in the communications area. If a Tag that has operated for a single
trigger designation (ST) is within the communications area, the ID Controller will not com-
municate with it a second time.
FR When the ID Controller receives a command, it waits until a Tag is detected within the
Antenna's communications area, then returns a response. After communicating, all further
operations with that Tag are prohibited. After returning the response, the ID Controller
again waits for a Tag to approach it, and continues until the COMMAND PROCESSING
TERMINATE (AA) command is received. The ID Controller communicates with only one
operable Tag in the communications area.
MT When the ID Controller receives a command, it communicates with all Tags in the commu-
nications area, then it returns a response after it has communicated with them all. After
communicating, all further operations with that Tag are prohibited.
MR When the ID Controller receives a command, it waits for a Tag to approach it. It communi-
cates with each Tag in the communications area, and returns a response. After communi-
cating, all further operations with that Tag are prohibited. After returning the response, the
ID Controller again waits for a Tag to approach it, and continues until the COMMAND PRO-
CESSING TERMINATE (AA) command is received.
SL The ID Controller performs a single trigger designation (ST) operation, and communicates
only with Tags having the UID that is designated by the command from among all of the
Tags in the Antenna's communications area.
