A.1 STAR-Link™ VISUAL BASIC 6.0 EXAMPLE

This example is a simple program based on STAR-Link™ ActiveX, that allows to:

− configure an RS485 base station network or a single base station in RS232

− save/load a network configuration from file (file RFNCCTL.CFG)

− start/stop PC/base station data collection

− collect data in a list

− write the main network events in a log file (file NRFCCTL.LOG)

− show data of PDF417 codes containing more than 240 characters and read by a

Gryphon™ M200. The code reconstruction is performed by Visual Basic source

code when Gryphon™ M200 has RF protocol version prior to 1.12. If using a

Gryphon™ M200 with an RF protocol version 1.12 or later, the code

reconstrunction will be performed by STAR-Link™ ActiveX. To get the current

RF protocol version of your RF hand-held reader, refer to the values of the

RFMinProtocolVersion and RFMaxProtocolVersion properties notified during the

device registration.

The main STAR-Link™ ActiveX events implemented in this example are: DataEvent,

ErrorEvent, AliveEvent, SatCfgEvent, StatusEvent, SleepSatEvent, LostFrameEvent.

At start up the program opens a dialog asking whether loading an existing

configuration:

Figure 5 - Loading an exisitng configuration

This allows to have always a configuration reporting all information about the network

devices.

For the same reason, another dialog box has been enabled when closing a

configuration to save it.
