Document ID: UG-i-PORT III NAE -23-
Scan
i-PORT settings for the scan process.
Mode 3 possibilities: “Host Only”, “Continuous” and “Input 1”
“Host Only” means that the i-PORT waits for commands, processes them, and is
otherwise inactive. “Continuous” means that the i-PORT performs continuous scans.
“Input 1” means that scans are triggered by “Triggerinput 1”
Slot Select Number of slots in which tags can answer; this is part of the anti-collision process. Set
at least double the amount of slots as the maximum number of tags that can be
located in the zone at one time. The elapsed time per slot in which tags can answer is
1.2 ms.
Num of Scans “Input1” Mode: Number of sequences executed by the i-PORT after Input1 again
becomes inactive. In “Test Mode”, this is also the number of scans.
Scan Pause Pause inserted by i-PORT after each sequence.
Data communication
i-PORT settings for tag communications (also dependent on the Inhibit Time!)
Data communication – Blink:
Setting to cause tags entering the zone to blink (dependent on Inhibit Time!)
Blink If this check box is marked off, each newly-recognized tag will blink. If Inhibit Time
is activated (>0), it must first elapse for the tag (reentering the zone) to blink
again.
Data communication – Read Data:
Settings for i-PORT to read data from tags (mark check box)
Power Boost Additional output power required for read process
Retries Number of maximum attempts to read data
Start Address The tag start address where the i-PORT will begin to read tag data.
Num of Bytes Number of bytes to read from the tag beginning from the Start Address
Data communication – Power Saving:
Settings for i-PORT to place tags into Sleep Mode (mark check box)
Mode 3 possibilities: “Sleep”, “Mute” or “Both”
Sleep, Mute, Both (i-Q): All 3 settings have the same effect for i-Q tags (sleep). For
this duration, the tags can no longer be communicated with (also from other i-PORTs).
After this time span has expired, the tags become available again.
Otherwise, the tag returns to normal mode, as it likewise does if it receives a signal
from a different i-PORT.
Mute (i-D2): Tags receive a signal, but give no answer for the duration of the “mute”. If
the tag receives a renewed signal from the same i-PORT, the time will be re-triggered.
Both (i-D2): Combination of Sleep and Mute!
