Chapter 3 — Developing and Using RFID Applications
RFID Applications and the IF5
About the IBM WRDI Option
66
The IF5 supports Java RFID applications. Your application
communicates with the IF5 through the Data Collection Engine
(DCE), and controls the reader by issuing Basic Reader Interface
(BRI) commands.
• For more information on the DCE, see
Data Collection Engine" on page 80.
• For more information on the BRI, see the Basic Reader
Interface Programmer's Reference Manual (P/N 937-000-xxx).
There are two ways to use the IF5 with your RFID application:
• You can run the application on a remote server. In this case,
all processing is performed by the server.
• You can run the application locally on the IF5. In this case,
the application resides on the IF5, and much of the processing
occurs on the IF5 and not remotely on the server. Such an
application is also known as edgeware, because the processing
is done at the "edge" of the network.
Running your application as edgeware on the IF5 improves
system scalability by minimizing network traffic, since the IF5
can handle many processing tasks such as data filtering.
If your application uses the IF5 GPIO interfaces to control
external devices such as indicator lamps, running the application
as edgeware decreases response time for those devices. For more
information, see Chapter 5, "Using the IF5 GPIO Interfaces."
You can set up your application to auto-start when the IF5 boots.
For more information, see
on page 70.
If you ordered the IBM WebSphere RFID Device Infrastructure
(WRDI) option for the IF5, you need to enable the IF5 WEDM
client so it starts at boot time. For help, see the next section.
After you enable the WEDM client, you can configure WEDM
client settings using the web browser interface. For help, see
"Configuring WEDM Settings" on page 95.
For more information, see the IBM WEDM documentation.
