SATELLINE-3AS User Guide, Version 2.2 2.3 RS-422 interface RS-422 standard defines a serial data transfer method, which is very similar to the RS-232 standard. 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 20
SATELLINE-3AS User Guide, Version 2.2 2.4 RS-485 interface RS-485 is an extension of the RS-422 standard and enables the connection of more than two devices on to the same bus. Communication is half-duplex, so there is only one cable pair, compared to two when using the RS-422. The RS-485 standard defines the electrical characteristics of the connections in such a way as to prevent possible data contention states as well as cable shorts etc. from harming the devices themselves. (See also Chapter 10.2.
PAGE 21
SATELLINE-3AS User Guide, Version 2.2 3 RF INTERFACE The Satelline-3AS(d) has a single TNC-type connector with impedance of 50 Ω. The Satelline3AS Epic model has two antenna connectors, the one on the left being both for transmitting and receiving and , the one on the right being for receiving only. When ordering the radio modem, the frequency band to which the radio modem will be tuned to at the factory must be defined.
PAGE 22
SATELLINE-3AS User Guide, Version 2.2 NOTE! Setting the radio data modem output power level to that which exceeds the regulations set forth by local authorities is strictly forbidden. The setting and/or using of non-approved power levels may lead to prosecution.

SATELLINE-3AS User Guide, Version 2.2 5 TRANSPARENT DATA TRANSMISSION 5.1 Serial interface, data format The SATELLINE-3AS radio modem 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 (b bits per second).
PAGE 32
SATELLINE-3AS User Guide, Version 2.2 5.2 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.

SATELLINE-3AS User Guide, Version 2.2 or even an interference signal caused for example, by a computer or a peripheral device. CD is also active when the radio modem in question is transmitting. 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.

SATELLINE-3AS User Guide, Version 2.2 buffered data has been transmitted. When the serial interface speed is the same or slower 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 the transmit buffer memory.
PAGE 35
SATELLINE-3AS User Guide, Version 2.2 6 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. For more information on routing, see Chapter 7. 6.
PAGE 36
SATELLINE-3AS User Guide, Version 2.2 6.2 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. SATELLINE-3AS radio modem allows the use of individual addresses both for reception and transmission.
PAGE 37
SATELLINE-3AS User Guide, Version 2.2 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: Address Data Address Data Data 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.
PAGE 38
SATELLINE-3AS User Guide, Version 2.2 Address Data Data ER R O R Data Data Address Data Reception addressing has been set OFF. Reception addressing been set OFF. has The radio modem will transfer all received data to the RS-232 interface. The radio modem will consider the characters of the address as a part of the data and will send all the characters to the RS-232 interface. Reception addressing has been set ON but there is no address in the data packet.
PAGE 39
SATELLINE-3AS User Guide, Version 2.2 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.
PAGE 40
SATELLINE-3AS User Guide, Version 2.2 S ADD DATA - The above is the same message after being relayed from the last repeater in the chain (repeater 2) to the substation. DATA - The above is the same message being relayed via the serial interface of the substation radio modem to the terminal device.
PAGE 41
SATELLINE-3AS User Guide, Version 2.2 6.3.3 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.
PAGE 42
SATELLINE-3AS User Guide, Version 2.2 7 MESSAGE ROUTING 7.1 Introduction to Message Routing Message Routing is a new and exciting feature in SATELLINE-3AS and Epic range. 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: • First, a radio modem reads any message coming from the terminal(s) attached to it.
PAGE 43
SATELLINE-3AS User Guide, Version 2.2 7.1.1 Features of Message Routing The Message Routing feature of the SATELLINE-3AS and Epic is designed to be a fast and transparent to fit real time systems. The features include: • Transparent to user protocols,. • Easy construction of a network containing several repeaters. • Any radio modem may operate as a repeater, i.e. dedicated repeaters are not usually needed thus cutting down on costs.
PAGE 44
SATELLINE-3AS User Guide, Version 2.2 7.1.4 Saterm 3 and the configuration of the Message Routing SaTerm 3 is a PC based program that allows the user to design their required network simply and quickly using a graphical interface to literally draw the network plan on the screen. • Firstly, a picture of the network is created to show all the radio modems and the intended route that the data is to take. • Secondly, the required settings are defined in the drawing.
PAGE 45
SATELLINE-3AS User Guide, Version 2.2 7.1.6 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.
PAGE 46
SATELLINE-3AS User Guide, Version 2.2 7.2 Operating modes of Message Routing The Message Routing has two different operating modes: • Source Mode Routing • Virtual Mode Routing The most important differences between the two modes are shown in the table below.
PAGE 47
SATELLINE-3AS User Guide, Version 2.2 7.3 Detailed description of Message Routing 3 0 1 Z X System Y Z 2 Modem 1, 2 1, 3 Y 7.3.1 Source Mode Routing The above figure represents a network containing four (4) radio modems. Each radio modem is given a unique address (0…3). A terminal device has been attached to the three of the four radio modems and they communicate with each other using terminal addresses X, Y and Z, respectively.
PAGE 48
SATELLINE-3AS User Guide, Version 2.2 7.3.2 Virtual Mode Routing 3 1 C A 2 X<-> 3 B 4 Z X Y <-> 2 Z <-> 1 1<-> 3 2<-> 4 D X<-> 4 Y The above figure represents the same network, which has now been created using the Virtual Mode Routing. The difference being that logical links are numbered instead of the radio modems. This configuration is easy to understand if you think of a telephone network constructed with traditional overhead wiring.
PAGE 49
SATELLINE-3AS User Guide, Version 2.2 7.3.3 Overhop function in Source Mode Routing t Master TD Radio R1 Master R2 Substation RD M R1 R2 TD S RD 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.
PAGE 50
SATELLINE-3AS User Guide, Version 2.2 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.
PAGE 51
SATELLINE-3AS User Guide, Version 2.2 8 Diversity receiver (SATELLINE-3AS Epic only) SATELLINE-3AS Epic model has two antenna connectors, one solely for reception and the other for both reception and transmission. Diversity reception means that the radio modem selects the best signal from both 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. 8.
PAGE 52
SATELLINE-3AS User Guide, Version 2.2 8.2 Antenna installation Signal fading appears at half wave intervals and so the best results are achieved by installing the two antennas of SATELLINE-3AS Epic so that the minimum separation distance is ¾ x wavelength used (min. 0.75 m). It is not recommendable to use Miniflex –antennas together with the SATELLINE-3AS Epic model.
PAGE 53
SATELLINE-3AS User Guide, Version 2.2 9 SETTINGS The configuration of SATELLINE-3AS radio modems can be easily changed. Simply by connecting pin 12 of the D-connector to ground (GND) the radio modem will switch into Programming Mode. Serial port 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).

In the following example both the transmitter output power (1000 mW ⇒ 20 mW) and the receiver sensitivity (-110 dBm⇒–90 dBm) are changed.
PAGE 56
SATELLINE-3AS User Guide, Version 2.2 The maximum useable sensitivity of the receiver is determined by the channel spacing (=radio interface data transfer speed) and also by error correction (utilised or not). For further information see Chapters 3.2, 10.3, 11.1 and 11.2. In environments with high levels of interference, and when connection distances are short, it is often beneficial to use a ”Signal threshold level” value, which is approximately 10 – 20 dBm above the maximum sensitivity level.
PAGE 57
SATELLINE-3AS User Guide, Version 2.2 9.1.3 Changing addressing settings (primary and secondary RX- and TXaddresses) Addressing can be switched ON or OFF with the help of main menu selection ”3”. In the following example a primary RX-address (transmitter address) is switched ON and the corresponding hexadecimal address value is modified (”0000” ⇒ ”0020”).

SATELLINE-3AS User Guide, Version 2.2 10.2 Connection cables NOTE! When installing the cables of the serial interface, the 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). 10.2.1 RS-232 wiring Basic RS-232 connection between the radio modem (PORT1) and a typical PC (COMport): 9-PIN D-CONN.

SATELLINE-3AS User Guide, Version 2.2 10.3 Antenna installation NOTE! 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. 10.3.1 • • Hand-held equipment ¼-wave antenna (wavelength at frequency of 450 MHz is approximately 70 cm) Helix-antenna Antennas are installed directly to the TNC-type antenna connector at the upper part of the radio modem. 10.3.
PAGE 88
SATELLINE-3AS User Guide, Version 2.2 10.3.4 General antenna installation instructions The reliability and the achievable coverage of useful signal strength can be severely affected by the positioning of the antenna. Antenna and cable connectors should have gold-plated pins and sockets, asuse of low quality connectors can lead to eventual oxidation of the connector surfaces which in turn may degrade the contact and cause additional attenuation.
PAGE 89
SATELLINE-3AS User Guide, Version 2.2 The type of the antenna cable is dependent on the length of the antenna cable, and the following table can be used to select a suitable type: Length <5m 0…20m >20m >20m Type RG58 RG213 NK Cable RFF 1/2"-50 AirCom+ Attenuation 10m/450MHz 3.0dB 1.5dB 0.7dB 0.8dB* *) AirCom+ cable is partially air insulated, so the use of this cable requires that the connection between the cable and the connectors are fully airtight.

SATELLINE-3AS User Guide, Version 2.2 11.2 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.
