RF SDK |
RF Software Development Kit (RF SDK) is a programmer's tool for
building RF data collection applications for PSC, Symbol, LXE,
Intermec, portable data terminals. Using any Windows development
environment that supports ActiveX controls, you can develop
sophisticated RF client/server applications using the TCP/IP
protocol.
The RF SDK allows Visual Basic, Foxpro, PowerBuilder and Access
programmers the ability to rapidly develop RF based
client/server applications for the PSC Falcon terminals. RF SDK
uses the TCP/IP protocol to communicate between the server
application running on the host and the included DOS client that
runs on the Falcon terminal. RF SDK is designed to handle up to
50 RF terminals simultaneously per server. A Windows client is
included to allow the developer to test the application quickly
in a simulator environment. RF SDK supports all the popular
radios including Cisco Airronet, Lucent's (Agere) Orinoco,
Proxim's RangeLAN 2, and Symbol's Spectrum24.
With the RF SDK, programmers now have an easy way to implement
RF solutions within their favorite development environment,
thereby reducing learning curve and minimizing customer support
time. An application developed with the RF SDK ActiveX controls
will communicate with the DOS client software that resides on
each Falcon RF terminal. The DOS client executable software is
provided as part of the RF SDK (the TCP library for the Falcon
terminal is also included).
A Windows client was created for testing purposes to simulate a
DOS terminal communicating with the RF Server. Once testing and
debugging are complete, your application can be loaded on the
Falcon portable for final testing. This utility is a helpful aid
for developers as it reduces testing time and minimizes hardware
configuration for testing purposes.
RF SDK Product Components
The RF SDK is made up of the following four components:
RF Server
The RF Server is a Winsock compliant application. Its function
is to listen for requests from any of the Falcon terminals. When
one of the Falcons makes a request, the Server responds by
starting a session for the application. From this point forward,
all communication is between the application and the Falcon.
Server Application
The Server Application provides you all the functions you need
to send and receive data to and from a Falcon. When adding this
Windows object into your development environment, it becomes
your Radio Frequency Library. You can use its Properties,
Methods and Events to design your client terminal screens for
data collection.
DOS Based Client for Falcon
The DOS based client handles the Falcon terminal interaction
between the user and the application running on a Server. It is
this ?thin' client that makes the initial request for a
connection to the Server and maintains the interaction with the
Falcon terminal operator.
Windows Client
Three Window's clients are included, all of which run on the PC
Server. A Small Windows Client, Large Windows Client, and
No-Keyboard Windows Client are provided to simulate different
terminals. These Windows clients are used to quickly test and
debug an application without having to load a Falcon terminal
each cycle.
Partial Listing of RF SDK Functions:
RF Server Controller:
ListenForConnectionRequest:
The ListenForConnectionRequest method is used to set the RF
Server control in listen mode.
ControllerClose:
Sets the listen mode of the RF Controller to off. Client
terminals will no longer be able to connect new sessions.
RF Server Application:
RFDisplay:
After sending all the necessary commands to build the screen on
the client terminal to the RFInitializeScreen structure, call
RFDisplay. The client will receive this command and paint the
screen with the completed structure.
RFEdit:
After instructing the client on how to format the screen and how
to terminate it, give control to the client for a response.
RF ScannerTextBox:
Allows entry of data from the scanning device only (nRow As
Integer, nCol As Integer, nLen As Integer, sText As string,
sMask As String).
KeyboardTextBox:
Allows entry of data from the keyboard only (nRow As Integer,
nCol As Integer, nLen As Integer, sText As string, sMask As
String).
ScannerKeyboardTextBox:
Allows entry of data from the keyboard or scanner (nRow As
Integer, nCol As Integer, nLen As Integer, sText As string,
sMask As String).
RFSessionParseBuffer:
Since there may be multiple responses buffered back to the
application control from a screen we provide the RFSessionParse-Buffer
method to extract various individual responses (Token As
Integer, Buffer As String).
RFEnd:
Terminates the client terminal connection.
Product Configurations
RF SDK Developer Edition:
This includes everything you need to create and test your
application (includes RF Server and Windows client for testing).
RF SDK Run-time:
A Run-time license is required for each server installation
(site) and includes the RF Server and a five user client license
for portable terminals.
Additional 5 User Client Licenses:
Additional client licenses can be purchased in blocks of 5
users.
