Single Trigger Communications Designation (ST)
With a Single trigger communications designation (ST), the ID Controller communicates with the Tag
when the command is received from the host device. When the ID Controller has completed communi-
cating with the Tag, it sends a response to the host device and then waits for another command. If
there is no Tag in the communications error when the ID Controller receives the command from the
host device, the ID Controller returns a Tag missing error (error code: 72). Use a sensor or other
means to confirm the presence of a Tag before sending the command.
Tag
Antenna
The Controller communicates with
a Tag in the antenna's communications
area when a command is received from
the host device. If there is no Tag, a
"no Tag" error is returned in the response.
