10 Controlling the Reader
The Reader uses RFID (Radio Frequency Identification) technology to read and write data stored on RFID
Tag(s).
The Sargas Reader provides three levels of access to control read/write operations of RFID tag(s):
1. Using the Browser-Based Interface
A web browser controls high-level Reader operations. See Status Page for information about how to access the
browser-based interface.
2. An application accessing the reader via MercuryAPI on a host, such as Universal Reader Assistant for
Windows PCs.
See the MercuryAPI Programmers Guide and the Universal Reader Assistant User Guide at
http://www.thingmagic.com/manuals-firmware
3. Directly address the reader from a host application via its LLRP protocol. EPCglobal ratified protocol used for
communicat
ion between the Sargas and a client application. The Sargas should be “drop-in compatible” with
systems supporting the standard LLRP protocol.
10.1 Using the Browser-Based Interface
The Sargas Reader browser-based interface communicates directly with the RFID Reader. It includes several
tools that enable you to monitor Reader performance, change Reader settings, and upgrade Reader firmware.
You can run the browser-based interface from any PC on the network. Carefully configure the PC with an IP
address and subnet mask compatible with the current operational settings of the Reader.
The Reader navigation menu provides access to the following pages:
Status Page
- Displays the current operational settings.
Settings Page
- Allows the user to modify Reader configuration and network settings.
The Read Page
. Allows the user to read on all configured antennas using the configured setting.
Firmware Upgrade Utility
- Upgrades the tag Reader with new firmware images provided by
ThingMagic.
Diagnostics Page
- Provides the current operating settings and access to the log files kept by the
Reader.
To start the browser-based interface:
1. Exit all Reader applications on the network.
WARNING -
Only one application may actively control the reader at any time. If a host is already
connected to the reader, you may view status and change configurations values, but not read tags.
Configuration changes made thorough one interface may not be displayed on the other interface. A
good rule of thumb is that the saved web interface changes become default values that are used on
start-up and, at the time the change is made, the current value. Changes made through the LLRP
interface override the values in current use, but are temporary and only last until the reader is rebooted.
