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” mode not available at this time.
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 expected in the zone at one time. The elapsed time per slot
in which tags can answer is 1.2 ms.
Num of Scans Number of consecutive scans completed when “Input 1” is asserted
(falling edge). In “Test Mode”, this is also the number of scans.
Scan Pause Pause inserted by i-PORT after each sequence (see page 28)
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.
Read data:
Settings for i-PORT to read data from tags (mark off check box)
Start Address Address from which i-PORT begins to read data
Num of Bytes Number of bytes that are read starting from the Start Address
Power Boost Additional output power (in dB) used for data reads
Retries Maximum number of attempts to read data. Retries will all be attempted on
the antenna with the highest field strength from subject tag on the most
recent tag scan.
Tag power saving:
Settings for i-PORT to send tags into Sleep Mode (mark off 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 cannot be communicated with by any reader (i-PORTs or
i-CARDs). After this time span has expired, the tags become available again.
Duration Duration of the Sleep/Mute mode
Detection:
i-PORT settings which determine which tag types to interrogate, and how.
Tag Type 3 possibilities: “i-Q”, “i-D” and “Both”
Depends on which tags need to be interrogated.
Mode 3 possibilities: “Normal”, “Max. Level” and “In/Out”
Normal: A tag is reported as soon as it enters the zone
Max. Level: Tag detection is reported when it is at maximum field strength
(see also “Detection Time”)
In/Out: Orientation recognition activated (Antenna 1…In, Antenna 2…Out,
Antenna 3…In, Antenna 4…Out)
Detection Time Max. Level Mode: Detection of tag at largest recorded field strength value
within the detection time interval
In/Out Mode: Detection of tag and calculation of orientation after detection
time interval
Inhibit Time If a previously interrogated tag leaves the zone for longer than the Inhibit
Time, it will be recognized as a new tag when it reenters the zone. If the tag
reenters the zone before expiration of the Inhibit Time, this time is reset as
if the tag had never left the zone. NOTE: This parameter needs careful
