5-2-5 Specifying a Tag Code: I.CODE1 Mode

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 between the

number of Tags and this setting.

〜8

〜16

〜32

〜64

〜128

Example: If the number of Tags is seven, select Tag Number setting 3.

Note:

● For the Multi Trigger(MT) and the Multi Read(MR), 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.)

● For the Special Read (refer to 5-2-1-6) command, the anti-collision process 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.
