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.

    SATELLINE-EASy User Guide, Version 2.3 6.2 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. The terminal can also control the radio modem via RTS-line.

However, when the serial interface speed exceeds the speed of the radio interface, data will eventually fill transmit buffer memory. In this instance, it will take a moment after the terminal device has stopped transmission of data for the radio modem to empty the buffer and before the transmitter switches off.

  • Page 87 SATELLINE-EASy User Guide, Version 2.3 When using repeaters, the same packet is sent via a (radio) channel several times. A radio modem situated in the repeater chain will often hear other radio modems in addition to the immediate neighbouring radio modems. With Source Mode Routing the complete address information is sent together with the packets enabling the use of these secondary routes.

    SATELLINE-EASy User Guide, Version 2.3 12 INSTALLATION 12.1 Installation of a Radio Data Modem The radio modem should be installed with the installation accessories supplied with the radio modem. There is also available an installation component for mounting the radio modem to a DIN-rail.

    12.1.1 Prepare installation of SATELLINE-EASy into the SATEL-321 casing Before installing a SATELLINE-EASy casing, the battery pack function must be selected as follows: NOTE! Both serial ports must be RS-232 (Not LV-/TTL or RS-422). To get RS-232 on Port 2, the PWR- module of the modem must be separately specified in the ordered.

    SATELLINE-EASy User Guide, Version 2.3 12.2.3 Base stations Omni-directional antennas ( - or 5/8-wave antenna) Directional antennas (yagi /multi-element antenna or corner antenna) The antenna should be installed in a vertical position. The exact location of the antenna depends on several factors, such as the size of the overall system and the coverage area terrain contours.
  • Page 92 SATELLINE-EASy User Guide, Version 2.3 When designing and installing a system it is advisable to prepare to test the system, and also to consider serviceability of the system. In particular cabling should be planned to allow easy access and to allow for maintenance. It is often practical to use long antenna cables, so that the radio modem can be installed far enough from the antenna itself to a location that is easily accessible (see section 10).
  • Page 93 SATEL recommends the use of a band-pass filter with a large Q in the antenna cable of the base station.

    The transmitter power of the SATELLINE-EASy 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 95: Radio Field Strength

    SATELLINE-EASy User Guide, Version 2.3 13.2 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.

    SATELLINE-EASy User Guide, Version 2.3 14 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 serial interface cable.
