GENERAL INFORMATION 1.4 1 RESET BUTTON This button deletes all RAM data restoring the last saved configuration. By pressing it for 2.5 seconds the yellow light starts blinking and it goes on by releasing the button. This light signals that STARGATE™ has entered the firmware downloading mode. While working in this mode the base station current configuration is deleted and substituted with the default one (Base station address = 2000; interface = RS232).
STAR ★ GATE™ 2 2 INSTALLATION 2.1 POSITIONING STARGATE™ Before connecting the STARGATE™ base station, it is first necessary to position it so that the RF transmission and reception is possible. To position STARGATE™, bear in mind the following fundamental guidelines: 1. the maximum distance between base station and RF device is about 50 m (in surfaces which are perpendicular to the base station antenna); 2.
INSTALLATION 2.1.2 2 Wall Mounting Before performing the following operation, mount the fixing plate on the STARGATE™ bottom surface by means of the four screws. Then, slide the wall mounting base along the fixing plate and fix it through the set - screw. Do not screw it too tight in order to allow the wall mounting base to slide out.

STAR ★ GATE™ 3 To configure the STARGATE™ base station use the cable and the adapter listed in par. 3.1. For further details see par. 4.3. CAUTION The RS485 bus system and the eventual power are propagated from one base station to another through a cable having the following minimum characteristics: − 2 twisted pair AWG 24 wire − Impedance: 120 Ω − Propagation velocity: 66% − Capacitance between two connectors: 49 pF/m − Conductor resistance: 0.
CONNECTIONS 3 If connecting up to 16 STARGATE™ base stations in the same system, it is necessary to use a custom cable having two different pinouts depending on the network configuration.
STAR ★ GATE™ 3 If using a shielded cable, it is necessary to link the cable shields together (see Figure 12) and connect them to the earth ground in only one point. We suggest to use your PC ground (when provided) to make the connection to the earth ground. Figure 12 - Linking the cable shields Network Termination Before proceeding with this operation ensure that the base station is not powered.
CONFIGURING AND TESTING STAR-System™ 4 4 CONFIGURING AND TESTING STAR-System™ 4.1 STAR-System™ OVERVIEW Two different layouts are provided depending on the application needs. Each layout may consist of a single STARGATE™ or a network of several RF base stations. An RF device is logically linked to only one STARGATE™ RF base station at a time. In case of a network layout it can choose dynamically the best base station to be linked to allowing the handover from one cell to another.
4 STAR ★ GATE™ If the system has been started correctly (invoking the proper STAR-Link™ ActiveX method) and the network initialization has been completed, the registration of the RF device in the network and the first data transaction occur at the same time. Then, the RF device will send information to the host PC identifying the RF device type and the RF library version. Finally, it will transmit the data packet taken from the application program.
CONFIGURING AND TESTING STAR-System™ 4 Be careful when installing two separate networks having overlapping RF coverage areas. In this case no RF device nor STARGATE™ RF base station must share the same address considering the total number of RF devices (see Figure 14).
STAR ★ GATE™ 4 Example If working with an installation composed of 4 point-to-point cordless systems (RF device with its base), 4 STARGATE™ RF base stations connected to 1 host PC via RS485 and 10 RF devices exchanging data with that host, a correct set of addresses could be: point-to-point: base stations 10 11 12 13 RF devices 10 11 12 13 network: STARGATE™ RF base stations (cannot be in range 10 – 13) 100 101 102 103 RF devices (cannot be in range 10 – 13) 50 51 52 53 54 55 56 57 58 59 18
CONFIGURING AND TESTING STAR-System™ 4.2 4 LOADING A SW APPLICATION ONTO AN RF TERMINAL The following example explains how to load the demo software (provided by the STAR-Link™ CD-ROM) onto an RF terminal: 1. Connect the terminal cradle to the PC COM1 by means of the serial cable and insert the RF terminal into its cradle; 2. Set the RF terminal to bootloader state (if it is already in this state jump to step IV); 3.
STAR ★ GATE™ 4 6. If the downloading procedure has completed successfully (after a series of messages about automatic tests have been displayed and several beeps have been emitted), the following message appears: DATALOGIC RF DEMO Any Key to start Or F4 to Set Press F4 and set the following parameters: Addr. F.Sta. L.Sta. Act. Dev.
CONFIGURING AND TESTING STAR-System™ 4.3 4 RS232 LAYOUT This procedure is intended to be a step-by-step guide explaining how to configure a STARGATE™ RF Base Station by using the Visual Basic example provided in the STAR-Link™ CD-ROM and based upon the STAR-Link ActiveX. The procedure assumes the STARGATE™ RF Base Station has a factory default address. If working with the base station previously configured, in step 4 digit the address value 2047 instead of 2000: 1. 2. 3. 4. 5. 6. 7. 8. 9.
STAR ★ GATE™ 4 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.
CONFIGURING AND TESTING STAR-System™ 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 4 Digit 2000 in the Edit box positioned in the right upper part of the dialog box and click on the Add button. The address will then be displayed in the list on the left; Select the 2000 address number from the list and click on the Config button. A window showing the STARGATE configuration parameters will appear; Double-click on the Address parameter and the Setting value dialog box will be displayed.
4 STAR ★ GATE™ 20. If the RS485 network is connected through a serial port different from the one previously used to configure the base stations, 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; 21. Set the first and the last base station addresses on the RF terminal (loading a software application as described in par. 4.
CONFIGURING AND TESTING STAR-System™ 4.5 4 NOTES FOR THE PROGRAMMER STARGATE™ does not carry out continuous polling, but it is only enabled each time a terminal sends it a sequence of data. This means the radio channel is always free when the RF devices are not transmitting. The media access procedure used to manage the shared RF channel is a Carrier Sense Multiple Access Collision Avoidance (CSMA/CA) protocol that aims to minimize the number of collisions of packets sent by different RF devices.
4 STAR ★ GATE™ Both the transactions (1 way and 2 way) must have an acknowledgement back to be completed correctly. This assures that the application program always knows if the data packet has been correctly delivered or not. In case the RF device does not receive the acknowledgement packet, the transaction fails due to timeout. Then, the device is not able to know if the data packet has correctly arrived to the network or not.
TROUBLESHOOTING 5 5 TROUBLESHOOTING PROBLEMS CAUSES REMEDY STARGATE™ is not powered. Supply STARGATE™. The connecting cable is broken or it is not correctly connected.
