  • Page 8: Introduction

    The amount of data transferred using local area networks is increasing constantly. On the other hand also the average size of a local area network is growing. SATEL has addressed these market requirements by introducing the SATELLINE-3AS radio modem family, which is the first SATEL manufactured radio modem to reach the wireless data transfer speed of 19,2 kbps.
  • Page 9 SATELLINE-3AS User Guide, Version 2.0 • SATELLINE-3AS radio modem largest data transfer speed is 19,2 kbps, channel spacing selectable as 25 kHz or 12,5 kHz (defined at the time of ordering). • SATELLINE-3AS radio modem is compatible with RS-232, RS-422 and RS-485 –interface standards.

In RS-422 however, the signal lines are balanced (or differential) transmission lines. A balanced (or differential) transmission line is formed by using two signal wires together to convey each single signal.

  • Page 19: Rs-485 -Interface

    The antenna connector is of the TNC-type with impedance of 50 Ω. There are two antenna connectors on Satelline-3AS Epic model. Transmitter and the other receiver is connected to the left side connector, while the other receiver to the right.

    The setting and/or using of non-approved power levels may lead to prosecution. SATEL is not responsible for any illegal use of its radio equipment, and is not responsible in any way of any claims or penalties arising from the operation of its radio equipment in ways contradictory to local regulations and/or requirements and/or laws.

  • Page 21: Receiver

    In the opposite case weak data transmissions will be rejected, although they would be otherwise acceptable. SATELLINE-3AS EPIC –radio modem contains two separate receivers, and a selection is made between the signals received by these two receivers so that the stronger/better signal is used. By this way the signal fading caused by multipath propagation will be smaller than in the case of using just one antenna and receiver.

  • Page 22: Error Correction

    User Guide, Version 2.0 2.2.4 Error correction SATELLINE-3AS includes the possibility to utilise an error correction method called the FEC- method (F F orward E E rror C C orrection). FEC-function is switched ON (or OFF) by using the configuration mode (SET-UP-mode). When activated, the FEC-function will cause the SATELLINE-3AS to automatically add additional error correction information, which increases the transmitted data by 30 %.

The status of the CD-signal on the RS-interface may differ from the status of the LED-indicator. 3.2 Configuration mode SATELLINE-3AS radio modem settings are fully configurable in configuration mode (SET-UP- mode) by using a suitable terminal program. The most recommendable set-up is ARS-1F connection cable adapter, CRS-9 cable, power supply and the SaTerm-terminal program.

  • Page 28: Handshake Lines

    SATELLINE-3AS User Guide, Version 2.0 4.2 Handshake lines When using the RS-232 serial interface, handshake signals can be used to control data transfer. Handshake signals are used for example by the radio modem to inform the terminal that the radio channel is busy and that it cannot initiate transmission. Also the terminal can control the radio modem via RTS-line.

  • Page 31: Repeater Mode And Addressesing

    In cases where it is necessary to extend the coverage area of a radio modem network, SATELLINE-3AS radio modems can be used as repeater stations. The maximum size of a repeated data packet is 1 kB (kilobyte). The repeater function is switched on using the configuration mode (SET-UP-mode).

  • Page 32: Addressing

    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 facilitates the use of individual addresses both for the reception and transmission. Addresses can be switched on separately or simultaneously in both data transfer directions.

  • Page 35: Using Repeaters And Addresses In The Same System

    SATELLINE-3AS User Guide, Version 2.0 For example, if the substation terminal devices are not able to check and form addresses by themselves, addressing may be accomplished 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.

    SATELLINE-3AS User Guide, Version 2.0 5.3.3 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 arrow in figure) is given a unique address, which will prevent duplication of messages and endless loops in the network.

    User Guide, Version 2.0 Diversity receiver (only SATELLINE-3AS Epic) SATELLINE-3AS Epic model has two antenna connectors, the other being used for reception and the other for reception and transmission. Diversity receiving means that the radio modem selects the best signal from 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 49: Antenna Installation

    Signal fading appears at half wave intervals. Because of this, best result is achieved by installing the two antennas of SATELLINE-3AS Epic apart from each other, so that the minimum separation distance is ¾ x wavelength used (min. 0.75 m). It is not recommendable to use Miniflex –...

    SATELLINE-3AS User Guide, Version 2.0 INSTALLATION 9.1 Installation of a Radio Data Modem The radio modem should be installed with the installation accessories supplied with the radio modem. There is also an installation part for mounting the radio modem to DIN rail available.

  • Page 78: Connection Cables

    When installing RS-Interface cables operating voltage of all devices must be off (POWER OFF condition). Due to the greater current consumption of SATELLINE-3AS EPIC operating voltage must be connected to pins 14 AND 15, and ground to pins 7 AND 8. Correct fuse rating is in this case 4 A (SLOW FUSE).

    User Guide, Version 2.0 9.3 Antenna installation NOTICE! NOTICE! Because of the great transmission power of SATELLINE-3AS EPIC radio modem, only an external antenna is allowed. A whip-antenna directly connected to the antenna connector must not be used. 9.3.1 Hand-held equipment •...

  • Page 83: General Antenna Installation Instructions

    SATELLINE-3AS User Guide, Version 2.0 9.3.4 General antenna installation instructions In cases where connection distances are long or in otherwise unfavourable cases the reliability of the radio connection depends on the antennas and the way they are installed. Antenna and cable connectors should also have gold-plated pins and sockets.
  • Page 84 SATEL recommends the use of a bandpass filter with a large Q in the antenna cable of the base station.
  • Page 85 User Guide, Version 2.0 Example of an antenna installation: Example of an antenna installation: by using amplifying antennas (G=Gain) and by installing the antenna high, long connection distances can be realised using the SATELLINE-3AS radio modem. G > 12 dBi G >...

  • Page 86: Designing Systems

    The transmitter power of the base model of SATELLINE-3AS is 1 W (maximum) and the sensitivity of the receiver better than -115 dBm. Thus in a flat area and in free space with a 1/4 wave antenna (antenna amplification 1dBi) and antenna height of 1 m communication distances of 3 to 4 km can be achieved.

  • Page 87: Radio Field Strength

    SATELLINE-3AS User Guide, Version 2.0 10.2 Radio field strength Radio signal strength must be good enough for successful data transfer. Where field strength is above a certain level the operational results are very good. Below this level, a few dB marginal areas occur in which errors begin to be generated by noise and interference that will eventually lead to loss of connection.

  • Page 88: Check List

    SATELLINE-3AS User Guide, Version 2.0 11 CHECK LIST The following points must be taken into account when installing and configuring a radio modem: 1. All operating voltages of all the equipment concerned must always be switched OFF before connecting the RS-interface cable.
