    SATELLINE-3AS and SATELLINE-3ASd RSSI = Received Signal Strength Indicator, can be used for monitoring the signal quality with a DTE. CTS = Clear To Send, used in handshaking. Indicates when the radio modem is ready to accept data on the TD line.

  • Page 12: Rs-422 Interface

    SATELLINE-3AS and SATELLINE-3ASd 5.1.1.3 RS-422 Interface RS-422 defines a serial interface much like RS-232. However, RS-422 uses balanced (or differential) transmission lines. Balanced transmission lines use two transmission lines for each signal. The state of each signal is represented by the relative voltage of the two lines to each other.

  • Page 13: Rssi Indicator

    SATELLINE-3AS and SATELLINE-3ASd 5.1.1.6 RSSI indicator Received Signal Strength Indicator, RSSI, ( pin 5) announces the received field strength of the signal. This signal can be used for the approximate determination of the signal level. In the following figure is the typical voltage level as a function of the signal level. Notice that voltage drops with a good signal level (>-25dB).

    SATELLINE-3AS and SATELLINE-3ASd 5.1.4 Display and push buttons (SATELLINE-3ASd) The SATELLINE-3ASd radio modem contains a back-lit liquid crystal display (LCD). The display shows the settings of the radio modem, field strength and battery charge condition. Using the LCD and the push buttons it is possible to change the settings of the radio modem without using an external terminal.

  • Page 17: Data Transmission (Rs-Interface)

    SATELLINE-3AS and SATELLINE-3ASd 5.2 Data Transmission (RS-interface) Data Transmission (RS-interface) 5.2.1 Data format The SATELLINE-3AS radio modem uses asynchronous data format. Asynchronous transmission does not require a continuous synchronising signal from the transmitter to the receiver. The data bits of each character are preceded by a start bit and followed by one or two stop bits. They are inserted after the data bits to provide a minimum period between characters.

  • Page 18: Handshaking

    SATELLINE-3AS and SATELLINE-3ASd The data settings of each station of the system can be different except for the data length. The data length must always be same in the whole system. The data format can be selected in the SETUP mode.

  • Page 19: Data Transmission (Radio-Interface)

    SATELLINE-3AS and SATELLINE-3ASd 5.3 Data Transmission (Radio-interface) Data Transmission (Radio-interface) 5.3.1 Addressing It is possible to use addresses both in data transmission and reception on the radio channel. The address consists of two data characters (totalling 16 bits). The address consists of the first two characters of the data packet, that the radio modem adds to every sent packet and/or checks for in every received packet.

  • Page 21: Error Correction

    SATELLINE-3AS and SATELLINE-3ASd 5.3.2 Error Correction SATELLINE-3AS offers the possibility to use Forward Error Correction (FEC), that can be set in the SETUP mode. If set, the SATELLINE-3AS adds extra FEC information to the data packets on the radio channel. The extra symbols give protection over noisy radio channels.

  • Page 22: Repeater

    SATELLINE-3AS and SATELLINE-3ASd 5.3.3 Repeater In case there is a need to extend the coverage of the radio modem network, the SATELLINE-3AS can be used as a repeater station. Data packets of maximum 1 kB (kiloByte) can be repeated. The repeater function has to be set on in the SETUP mode.
  • Page 23 SATELLINE-3AS and SATELLINE-3ASd In a system with several adjacent repeater stations addresses should be used. This prevents circulation of the message and secures that only the determined radio modem receives the message. All radio modems should have RX addressing set on and TX addressing set off. The base station and substation terminals add a chain of addresses to the beginning of the data sent to radio modem on the RS-line.

  • Page 47: General Rules

    SATELLINE-3AS and SATELLINE-3ASd 7.3.4 General rules In great distances or in otherwise severe conditions the operation of radio communication is dependent on antennas and their mounting. In antennas, antenna cables and terminal adaptors there should always be a gold plated connector. Since connectors of poor quality oxidate and increase the attenuation in the course of time appropriate connectors and proper tools must always be used in mounting.
