  • Page 36: Repeater Mode And Addressing

    SATELLINE-3AS User Guide, Version 2.3 6 REPEATER MODE AND ADDRESSING Repeaters and addressing may be used to extend the coverage area of a radio modem network, and to direct messages to selected radio modems in the network. In large systems, with several repeaters and formed repeater chains, it is often practical to use routing instead of plain addresses.

  • Page 37: Addressing

    SATELLINE-3AS User Guide, Version 2.3 6.2 Addressing Addresses can be used to route a data message to the desired destination or to separate two parallel networks from each other. In networks with repeaters it is usually necessary to use addresses to prevent data messages from ending up in loops formed by repeaters. SATELLINE-3AS radio modem allows the use of individual addresses both for reception and transmission.

  • Page 40: Using Repeaters And Addresses In The Same System

    SATELLINE-3AS User Guide, Version 2.3 For example, if the substation terminal devices are not able to check and form addresses by themselves, addressing may be achieved with the help of the addresses of the radio modems attached to these terminal devices. The base station may, in such a case, define the destination of a message by adding the address of the corresponding radio modem into the beginning of the data packet.

  • Page 42: Repeater Chain Using Dual Addressing

    SATELLINE-3AS User Guide, Version 2.3 6.3.3 Repeater chain using dual addressing If the terminal devices cannot add address chains to the beginning of the data packets, a network with several repeaters may still be realised by using dual addressing. In dual addressing each link (see arrows below in figure) is given a unique address, which will prevent duplication of messages and endless loops in the network.
  • Page 43 SATELLINE-3AS User Guide, Version 2.3 If "TX address autoswitch" has been set ON (see chapter 9.1.3), radio modem checks out the RX address of the received message. When the secondary (/primary) RX address is recognised, all the messages coming in from the serial interface will be sent to the air with secondary (/primary) TX address until a message with primary (/secondary) RX address is received from the radio.

    SATELLINE-3AS User Guide, Version 2.3 8 Diversity receiver (SATELLINE-3AS Epic only) SATELLINE-3AS Epic model has two antenna connectors, one solely for reception and the other for both reception and transmission. Diversity reception means that the radio modem selects the best signal from both those received by the two antennas. In this way the reliability of the connection is improved especially in those cases which are subject to a high level of reflections and multipath fading.

  • Page 54: Antenna Installation

    SATELLINE-3AS User Guide, Version 2.3 8.2 Antenna installation Signal fading appears at half wave intervals and so the best results are achieved by installing the two antennas of SATELLINE-3AS Epic so that the minimum separation distance is ¾ x wavelength used (min. 0.75 m).
