SATELLINE-4Pro User Guide v0.93 DRAFT 3 SATELLINE-4Pro SPECIAL FEATURES 3.1 Call Sign SATELLINE-4Pro has a CALL SIGN identifier -feature required in some countries. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise identity of a station. A call sign is an FCC (in US) or other regulatory authority assigned identifier that is issued along with the license for operating a radio modem.
SATELLINE-4Pro User Guide v0.93 DRAFT power goes to 2W, at 80°C to 10W, at 78°C to 20W, at 75°C to 25W and at 73°C the modem operates again at the full 35W carrier power. 3.3 Protection of current In case of a bad antenna impedance matching the current consumption of the Power Amplifier may be too high. For this reason the maximum current is limited to 12 A. If the current tends to increase over 12 A, the automatic power control decreases the power level until the current drops under 11.5 A.
SATELLINE-4Pro User Guide v0.93 DRAFT 4 SERIAL INTERFACE The radio modem is referred to as DCE (Data Communication Equipment) whereas the PC is referred to as DTE (Data Terminal Equipment). SATELLINE-4Pro includes a 8 pin ODU which contains all the connections required to establish communication between the radio modem, acting as the DCE, and the PC, acting as the DTE. All EMC-requirements set forth by authorities have been taken into account in the design of the radio modem.

SATELLINE-4Pro User Guide v0.93 DRAFT 6 CONNECTION INTERFACES NOTE! When installing the cables of the serial interface, it is recommended that the operating voltage of all devices is powered OFF. 6.1 RS-232 interface RS-232 standard defines the method of serial data transfer between a computer and its peripherals. The definition includes both the interface type and signal levels. Most computers and peripherals contain one or more RS-232 type serial ports.
SATELLINE-4Pro User Guide v0.
SATELLINE-4Pro User Guide v0.93 DRAFT 7 RF INTERFACE The SATELLINE-4Pro 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 63.82 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 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 (BER 10E-3): 4FSK FEC OFF 4FSK FEC ON 8FSK FEC OFF 8FSK FEC ON 16FSK FEC ON 12.
SATELLINE-4Pro User Guide v0.93 DRAFT 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-4Pro 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 7.7 User 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. NOTE! All radio modems, which are to communicate with each other, must have the same setting for Data whitening (ON or OFF).
SATELLINE-4Pro User Guide v0.93 DRAFT 7.8.2 Configuration by using SL commands “SL@S=” command selects the compatibility mode: ”SL@S=0” sets SATELLINE-3AS (default). ”SL@S=1” sets PCC-4FSK ”SL@S=2” sets PCC-GMSK ”SL@S=3” sets TRIMTALK GMSK, RX fitted to Pacific Crest transmitters “SL@S=4” sets TRIMTALK GMSK, RX fitted to Trimble transmitters “SL@S=5” sets PCC-FST The modem responds with “OK” message if the requested mode is supported or “ERROR” if the mode is not allowed.

SATELLINE-4Pro User Guide v0.93 DRAFT Note 2. If error correction is ON (FEC ON) and TRIMTALK mode is activated by using ”SL@S=3” command, the firmware automatically switches SATEL FEC OFF temporarily, and turns it back at the mode return. 7.8.5 Support for Local / Remote addresses If the modem has TX address ON then primary TX address is handled in the same way as Remote address in Pacific Crest PDL modems. The default value is 0x00FF (255 in decimal format) i.e. the broadcast address.
SATELLINE-4Pro User Guide v0.93 DRAFT 7.8.6.1 Transmission delays using Pacific Crest 4FSK on 25 kHz channel The table below presents the typical latency vs. the size of the message. The delays are measured from the end of transmitted data to the end of received data on the serial interface.

SATELLINE-4Pro User Guide v0.93 DRAFT 8 TRANSPARENT DATA TRANSMISSION 8.1 Serial interface, data format The SATELLINE-4Pro 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 9600, 19200, 38400, 57600 or 115200 bps (bits per second).
SATELLINE-4Pro User Guide v0.93 DRAFT 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). 8.2.1 CTS-line The options for CTS-line are: 1) Clear To Send CTS is active when the radio modem is ready to accept data for new transmission.
SATELLINE-4Pro User Guide v0.93 DRAFT 8.3.1 Data buffering in the radio data modem Whenever the radio modem is in Data Transfer Mode it monitors both the radio channel and the serial interface. When the terminal device starts data transmission the radio modem switches to transmission mode. At the beginning of each transmission a synchronisation signal is transmitted and this signal is detected by another radio modem, which then switches into receive mode.
SATELLINE-4Pro User Guide v0.93 DRAFT The maximum absolute time is always 170 ms independent from the value of the Pause length given in the set-up. An increase in the Pause length increases the round trip delay of the radio link correspondingly; this is due to the fact that the radio channel is occupied for the time of the Pause length after each transmission (the time it takes to detect a pause). If this is not acceptable, the TX delay setting may also be useful in special cases. 8.3.

SATELLINE-4Pro User Guide v0.93 DRAFT 10 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. 10.
SATELLINE-4Pro User Guide v0.93 DRAFT 10.2 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. SATELLINE-4Pro allows the use of individual addresses both for reception and transmission.
SATELLINE-4Pro User Guide v0.93 DRAFT Transmission: Transmission address has been set OFF. Radio modem will transmit the data packet as such. 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-4Pro User Guide v0.93 DRAFT Reception addressing has been set OFF. Reception addressing been set OFF. 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. 10.2.1 has Reception addressing has been set ON but there is no address in the data packet.
SATELLINE-4Pro User Guide v0.93 DRAFT 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-4Pro User Guide v0.93 DRAFT 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 10.3.3 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-4Pro User Guide v0.93 DRAFT 11 INSTALLATION 11.1 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 11.1.2 Fuse A proper fuse must be connected in between the radio modem and the power supply. The correct value is 15A for SATELLINE-4Pro. 11.1.3 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-4Pro User Guide v0.93 DRAFT 11.2 Antenna installation NOTE! Because of the great transmission power of SATELLINE-4Pro radio modem, only an external antenna is allowed. A whip-antenna directly connected to the antenna connector must not be used. 11.2.1 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 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. The best way to distinguish from the other antennas situated in the neighbourhood is to mount the antennas as far as possible from each other on the altitude level.
SATELLINE-4Pro User Guide v0.93 DRAFT 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-4Pro radio modem.
SATELLINE-4Pro User Guide v0.93 DRAFT 12 DESIGNING SYSTEMS 12.
SATELLINE-4Pro User Guide v0.93 DRAFT 12.2 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.
SATELLINE-4Pro User Guide v0.93 DRAFT 13 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. 2.
