5-10 Timeslot Setting
The timeslot setting is the setting in the command frame when communicating with multiple Tags
simultaneously using Multi-system commands. This setting must be set according to the number of
Tags with which to communicate simultaneously. Refer to the table below for the relationship be-
tween the number of Tags and this setting.

cation is possible

Example: If the number of Tags is seven, select Tag Number setting 3.
Note
•
If more Tags than have been set using the timeslot setting enter the
communications range, a "70" error (warning) may occur. (e.g., When
the timeslot setting is "2" and there are five Tags in the communications
area.)
Select a suitable setting by referring to the above table.
•
For the Special Read (refer to 5-2-1-6) command, the anti-collision proc-
ess is not performed. Therefore, read data will be returned even If there
are more Tags than the timeslot setting in the communications area.If a
collision occurs, such data will not be returned.
•
The higher the timeslot setting is, the longer the communications time is
required. Consequently, setting a higher timeslot setting than required for
the number of Tags in use unnecessarily lengthens communications time,
so select a suitable setting.
