PAGE 23
SATELLINE-EASy Pro 35W User Guide v.0.2 7 RF INTERFACE The SATELLINE-EASy Pro 35W has a single TNC type RF-connector with impedance of 50 Ohm. When the modem, is supplied the frequency is set to “default channel”. The user can change the frequency afterwards by 70 MHz. Of course, all local regulations set forth by the authorities must be taken into consideration. The data speed of the radio interface is set to “default speed”. It can also be set afterwards.
PAGE 24
SATELLINE-EASy Pro 35W User Guide v.0.2 7.2 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) according to the table below: Channel spacing 25 kHz 20 kHz 12,5 kHz FEC OFF FEC ON -108 dBm -111 dBm -111 dBm -111 dBm -114 dBm -114 dBm The Signal Threshold Level setting of the receiver determines a level, above which the search for the actual data transfer signal is active.
PAGE 25
SATELLINE-EASy Pro 35W User Guide v.0.2 7.4 Forward Error Correction Forward Error Correction, FEC-function is switched ON (or OFF) by using the Programming Mode. When activated, the FEC-function will cause the SATELLINE-EASy Pro 35W to automatically add additional error correction information, which increases the amount of transmitted data by 30 %. It is used by the receiving radio modem to correct erroneous bits - as long as the ratio of correct and erroneous bits is reasonable.
PAGE 26
SATELLINE-EASy Pro 35W User Guide v.0.2 7.6 Dual radio function, separate RX/TX-frequencies The SATELLINE-EASy can transmit (TX-frequency) and receive (RX-frequency) on separate frequencies. Separate frequencies can be set within the whole tuning range. The frequencies can be set in the display menu, in the programming mode or by the Configuration Manager. When data flow on the TD line starts the frequency shifts from the receiving channel to the transmit channel.
PAGE 27
SATELLINE-EASy Pro 35W User Guide v.0.2 7.8 Data whitening In some cases, if the user data includes a large number of constant characters, additional bit errors may appear. The use of error correction (FEC) is recommended in such cases. If that is not possible, the Data whitening feature can be used to improve the reliability of data transfer. The feature is set on/off in the programming mode.
PAGE 28
SATELLINE-EASy Pro 35W User Guide v.0.2 8 TRANSPARENT DATA TRANSMISSION 8.1 Serial interface, data format The SATELLINE-EASy Pro 35W serial interface uses an asynchronous data format. No external synchronising signal is needed, since necessary timing information is acquired from the start and stop bits transmitted before and after each data field bits (byte). The data transfer speed of the serial interfaces can be set to 300, 600, 1200, 2400, 4800, 9600, 19200 or 38400 bps (bits per second).
PAGE 29
SATELLINE-EASy Pro 35W User Guide v.0.2 8.2 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.
PAGE 30
SATELLINE-EASy Pro 35W User Guide v.0.2 2) Data on channel CD will switch to active state only after recognition of a valid data transmission. CD will not react to interference signals. 3) Always ON CD is always in the active state. This option can be used with terminal equipment, which use the CD-line as an indicator of an active connection (the radio modem can transmit and receive at any time). 8.2.3 RTS-line The options for RTS-line are: 1) Ignored RTS-line status is ignored.
PAGE 31
SATELLINE-EASy Pro 35W User Guide v.0.2 than the speed of the radio interface, the internal transmit buffer memory cannot overflow. 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. The maximum size of transmit buffer memory is one kilobyte (1 kB).
PAGE 32
SATELLINE-EASy Pro 35W User Guide v.0.2 8.3.3 TX delay The radio modem can be configured to delay the beginning of a radio transmission by 1...65000 ms. This function can be used to prevent packet contention in a system, where all substations would otherwise answer a poll of a base-station simultaneously. During this delay data sent to the radio modem is buffered. Although the priority setting is "RX", radio modem is prevented to change over to receiving mode during the period of the TX delay.
PAGE 33
SATELLINE-EASy Pro 35W User Guide v.0.2 The strength of the received signal can be monitored using the LCD-display of the receiving radio modem. NOTE 1! Green TD led indicates active test mode. NOTE 2! Normal data transfer is not available while the Test mode is active. Remember to switch it OFF before starting the normal data transfer. NOTE 3! Message Routing and FCS mode must be disabled prior to set ON the Test mode.
PAGE 34
SATELLINE-EASy Pro 35W User Guide v.0.2 9 SETTINGS The configuration of SATELLINE-EASy Pro 35W can be easily changed. Simply by connecting MODE pin (see chapter 6.2) of the data connector to ground (GND) the radio modem will switch into Programming Mode. Serial PORT 1 is used whenever the radio modem is in the Programming Mode. The serial port settings are 9600 bps, N, 8,1 (data transfer speed 9600 bps, no parity, character length 8 bits and one (1) stop bit).

SATELLINE-EASy Pro 35W User Guide v.0.2 12 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. 12.
PAGE 68
SATELLINE-EASy Pro 35W User Guide v.0.2 12.2 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. In case of setting the “Message Routing” function in use, Tx / Rx addresses are ignored by the modem.
PAGE 69
SATELLINE-EASy Pro 35W User Guide v.0.2 Transmission: Address Data Data Data Transmission address has been set OFF. Radio modem will transmit the data packet as such. Data Transmission addressing has been set ON. The radio modem will add the primary TX address to the beginning of the data packet. Reception: Reception addressing has been set ON and either the primary or secondary RX address of the radio modem is identical to the address of the received data packet.

SATELLINE-EASy Pro 35W User Guide v.0.2 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.

SATELLINE-EASy Pro 35W User Guide v.0.2 12.3.3 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. The terminal devices need not add anything to the data.

SATELLINE-EASy Pro 35W User Guide v.0.2 13 MESSAGE ROUTING 13.1 Introduction to Message Routing Message Routing is an exciting feature in SATELLINE-EASy Pro 35W. This feature allows messages from terminal devices to be automatically routed over the radio modem network to a specified recipient terminal. In brief, the Message Routing works as follows: o First, a radio modem reads any message coming from the terminal(s) attached to it.
PAGE 75
SATELLINE-EASy Pro 35W User Guide v.0.2 13.1.1 Features of Message Routing The Message Routing feature of the SATELLINE-EASy Pro 35W is designed to be a fast and transparent to fit real time systems. The features include: o Transparent to user protocols. o Easy construction of a network containing several repeaters. o Any radio modem may operate as a repeater, i.e. dedicated repeaters are not usually needed thus cutting down on costs.

PAGE 77
SATELLINE-EASy Pro 35W User Guide v.0.2 13.1.6 Configuration of the protocol in Message Routing A radio modem will detect the presence of an address used by inspecting the protocol from the message received via the serial interface. On the basis of this user address, all necessary information needed to relay the message to destination is fetched from an internal routing table inside a radio modem.

SATELLINE-EASy Pro 35W User Guide v.0.2 R1 M R2 The overhop function allows for the use of mobile substations. In the example above, a mobile substation is first located in the coverage area of repeater R2. The route is defined as M, R1, R2 and vehicle. When the vehicle moves to the coverage area of repeater R1, the radio modem picks the packet already from the transmission of R1.

SATELLINE-EASy Pro 35W User Guide v.0.2 14 INSTALLATION 14.1 Installation of a Radio Data Modem The radio modem should be installed with the installation accessories supplied with the radio modem. NOTE! When selecting a suitable location for the radio modem it must be ensured that no water can get into the radio modem under any conditions. Direct sunlight is also to be avoided. It is not recommendable to install the radio modem on a strongly vibrating surface.
PAGE 82
SATELLINE-EASy Pro 35W User Guide v.0.2 14.1.2 Fuse A proper fuse must be connected in between the radio modem and the power supply. The correct value is 15A for SATELLINE-EASy Pro 35W. 14.1.3 Power supply The allowed operating voltage is +9 ... +16 VDC. The radio modem must only be connected to a power supply with an adequate current output (power rating minimum is 120W). The pins 1 and 2 of the 4pin Odu-connector are connected to the positive power supply line.

SATELLINE-EASy Pro 35W User Guide v.0.2 14.2 Antenna installation NOTE! Because of the great transmission power of SATELLINE-EASy Pro 35W radio modem, only an external antenna is allowed. A whip-antenna directly connected to the antenna connector must not be used. 14.2.1 o o Mobile equipment ¼-wave antenna ½-wave antenna The ideal installation position is vertical, and there should be at least 0.5 m of free space around the antenna. In small systems a ¼-wave antenna is sufficient.
PAGE 84
SATELLINE-EASy Pro 35W User Guide v.0.2 Antennas must be installed well away from metallic objects. In the case of small antennas this distance should be at least ½ m. With large antennas the distance should be >5 m and in case of repeater antenna combinations >10 m. If the system contains a large number of radio modems, the best location for an antenna is the highest point of a building and possibly an additional antenna mast.
PAGE 85
SATELLINE-EASy Pro 35W User Guide v.0.2 if the data transmission protocol is well prepared for this and the data transmission that occasionally slows down does not cause any problems to the system. Vertical polarised antennas (antenna elements are in vertical position) are often used in radio systems. In a system between a base station and substations vertical polarisation is recommended. The radio modem antenna cannot be mounted on the same level as the other substation antennas in the same building.
PAGE 86
SATELLINE-EASy Pro 35W User Guide v.0.2 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-EASy Pro 35W radio modem. The distances in picture are to SATELLINE-EASy Pro 35W.

SATELLINE-EASy Pro 35W User Guide v.0.2 15.2 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. The field strength is at its optimum level in open space, although increasing distance will still reduce it.
