  • Page 28: Cts Line

    SATEL-EASy+ User guide Version 1.33 Handshaking is not needed if the system protocol is designed to prevent collisions (data contention) by the use of polling, or if there is little traffic and also if there is no harm from occasional data contention situations (several radio modems try to transmit at the same time).

  • Page 33: Receiver

    SATEL-EASy+ User guide Version 1.33 6.2 Receiver The sensitivity of the receiver depends on the channel spacing of the radio modem (=data speed of the radio interface) and on the mode of the FEC (error correction). The radio modem constantly measures the received signal strength (RSSI) of the receiver. The Signal Threshold setting determines the received signal level above which the search for the radio messages is active.

  • Page 34: Forward Error Correction (Fec)

    SATEL-EASy+ User guide Version 1.33 6.4 Forward Error Correction (FEC) FEC improves the reliability of data transfer over the radio by adding additional correction information to the radio messages. Based on that information, the receiving radio modem will be able to correct erroneous bits provided the ratio of erroneous and correct bits is reasonable.

  • Page 35: Satelline-3As Mode

    SATEL-EASy+ User guide Version 1.33 Full Error Check In this mode the radio modem waits until the end of the reception and checks the whole received message before forwarding it to DTE. The additional time delay compared to No Error Check is roughly the time needed to transfer the user data message over the serial line.

In large systems, with several repeaters and formed repeater chains, it is often practical to use routing instead of plain addresses.

  • Page 66: System With Several Repeaters

    SATEL-EASy+ User guide Version 1.33 13.3.1 System with several repeaters In systems with several serial or parallel-chained repeaters, addressing must be used to prevent messages from ending up in loops otherwise formed by repeaters, and to ensure that only the desired (addressed) radio modem receives the data intended for it.
