STAR ★ GATE™

10. Set the STARGATE™ new address on the RF terminal (loading a software

application as described in par. 4.2) as first and last base station to which

sending the data packets in 1way or 2 way mode (see par. 4.5). To make Visual

Basic answer to a device sending data in 2 way mode it is necessary that the

device belongs to the list of the network devices. (Before starting the polling

procedure, register the device address by selecting the Devices option from the

Settings menu and adding the new address to the list);

11. Save the current network configuration (PC/STARGATE™ communication

parameters, list of base stations and devices belonging to the network) by

selecting the Save configuration option from the Settings menu. When running

the program in Visual Basic again, and selecting the option Load configuration

from the Settings menu, you do not need to configure the network to start the

data polling;

12. Select the Open option from the Network menu to start polling STARGATE™.

Now, the program is ready to display the data packets sent to the base stations

in the application window.

4.4 RS485 LAYOUT

This procedure is intended to be a step-by-step guide explaining how to configure an

RS485 network composed of N number of STARGATE™ RF Base Stations. This

procedure assumes the STARGATE™ RF Base Stations have a factory default

address. If working with base stations previously configured, in step 5 digit the

address value 2047 instead of 2000. Before connecting the base stations to the

RS485 network, it is necessary to set the right address and the RS485 interface for

each base station. We also suggest to apply a label on each STARGATE™

indicating the corresponding address:

1. Define a set of consecutive addresses to be assigned to the N number of

base stations (the range is from 0-1999); for example, from M to (M+N-1). Refer

to par. 4.1 for details;

2. Connect the first STARGATE™ to the PC serial port and power it (see

Figure 4);

3. Run the Visual Basic demo example on the PC: click the Windows Start

button, select Visual Basic example from the path Programs➙Datalogic➙STAR-

Link➙Examples; then, the STAR-Link VB Example dialog box will be displayed.

If the connection does not use COM1 port (default serial port), select the Control

settings option from the Settings menu. The Properties settings dialog box

appears allowing to select a different port. Then, click OK to confirm the new

value and close the dialog box;

4. Select the Base stations option from the Settings menu: the RF Base stations

dialog box appears;
