STARGATE™ maintains the data for a maximum of 3 hours. Then, data is definitely lost. This feature is only available from the software release 1.10 referring to the software running on the base station and displayed when enabling the Alive button in RS232 connection (see step 8 in par. 4.3). 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 (30 m for STARGATE™ USA model) in surfaces which are perpendicular to the base station antenna; 2. the effective radio coverage depends on the physical structure of the environment in which it operates, and to the presence or absence of obstacles (metal structures, walls, electrical systems, etc.); 3. the base station operates at temperatures between -20° (-4°) and + 50 °C (+122 °F), with humidity at less than 90% (no condensation); 4. to obtain the best reception/transmission performance, mount the STARGATE™ base station away from large metal structures which could absorb or reflect Radio Frequency; STARGATE™ can be mounted for desktop usage or it can be fixed to a wall. 2.1.1 Desktop Use For desktop use, STARGATE™ is already correctly positioned : 1. Carefully clean the rubber feet seat of the STARGATE™ base to remove any impurities that could reduce adhesion; 2. Remove the protective plastic from the rubber feet and stick them onto the bottom surface of the base; 3. Insert the antenna in the appropriate hole on the body of the base station and screw it clockwise until tight. If working with a STARGATE™ USA model, skip step 3, since the antenna is fixed and not removable. CAUTION 2.1.2 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.

Using the mounting holes on the plate as a pattern mark the wall where you desire to mount STARGATE™; 2. Drill two appropriate size holes; 3. Insert the threaded dowels into the holes; 4. Position the plate on the wall and affix it by means of the two screws; 5. Insert STARGATE™ (as shown in Figure 3) by sliding the fixing plate along the guide on the mounting base; 6. Fix it by means of the set - screw if necessary.

The (first) base station is connected to the PC through an F904/N RS232/485 converter set to the following default parameter values (see the F904/N relevant manual for details): . baud rate: 38400 bps . data bits: 8 . parity: none The power can be either individually supplied to each STARGATE™ present in the system or propagated from one base station to another by means of a single power supply (see Figure 10 and Figure 11 for further details). Figure 8 - RS485 Connection The cables, converter and power supplies are listed with their order number: A. 94A054000 2 m serial cable B. 94ACC4470 F904/N RS232/RS485 converter C. 94ACC4050 power supply 110 V (USA) 94ACC4060 power supply 240 V (UK) 94ACC4070 power supply 220 V (EURO) 94ACC4500 power supply 240 V (Australia) D. Custom cable (see Figure 9) E. Custom cable (see Figure 10 and Figure 11) 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 . . Propagation velocity: 66% . Capacitance between two connectors: 49 pF/m . Conductor resistance: 0.8 ./m . Maximum length: 1200 m Pinout The custom cables to be used in the RS485 connection have two RJ45 connectors (see Figure 5). The cable connecting the first base station to the RS232/RS485 converter has the following pinout: 6 7 RJ45 2 1 RJ45 CONVERTER side STARGATE™ side Twisted Pair RS485+ RS485- 3 5 VDC- Figure 9 - Converter/STARGATE™ Custom Cable Pinout If connecting up to 16 STA...
