Reader Settings
The Reader Settings screen allows you to see and change certain parameters of the RFID reader,
such as transmit power, and some Gen2-specific parameters on the RFID tab. There is a second
Network tab with some additional parameters related to the reader’s network interface and some
common Alien features, such as a Heartbeat and TagStream functionality.
To commit any changes made on the Reader Settings pages, you must click the OK button at the
lower-right corner. Clicking the Cancel button or the Close (X) button in the top-right corner returns
you to the main screen without applying any of the changes that you made.
The RFID tab has controls for RF Power and some Gen2
parameters, such as Session, Q, and Inventory Target.
You can configure the Inventory demo to send Select
(“wake up”) commands to tags for an amount of time at
the start of each tag search, and there’s an option to
disable tag write operations on the Access demo.
Units configured for some regions may also provide
checkboxes for selecting specific frequency channels.
The RFID module firmware version and configured
region are displayed in the bottom corner.
The Network tab shows the reader’s
MAC and IP addresses, as well as fields
and checkbox controls for the Heartbeat
server (for UDP-based discovery), and a
TCP-based TagStream feature.
