SATELLINE-M3-TR1 User Guide, Version 1.4 2 Operating Voltage 2.1 Operating Voltage (PWR-module) The SATELLINE-3AS-TR1 radio modem can have two (2) operating voltage ranges. The range is set at the factory. The voltage level must be mentioned in the order. The operating voltage range is changed by replacing the PWR-module. The operating voltages are: 3.2-8.5 VDC or 6.5V - 28 VDC +/-10%. The nominal voltages are 3-9V and 6-30V.
SATELLINE-M3-TR1 User Guide, Version 1.4 Picture3 Press the new PWR module back in reverse order. Picture 3 2.2.1 Fuse A proper fuse must be connected in between the radio modem and the power supply. The correct value depends on the model (see list below). Recommended value is 2A slow. 2.2.2 Power supply The radio modem must only be connected to a power supply with an adequate current output. The pins 15 and 14 of the D-connector are connected to the positive power supply line.
SATELLINE-M3-TR1 User Guide, Version 1.4 3 SERIAL INTERFACE The radio modem is referred to as DCE (Data Communication Equipment) whereas the PC or equivalent device is referred to as DTE (Data Terminal Equipment). The SATELLINE-M3-TR1 radio modem include a 15-pin ‘D’-type female connector, which contains all the connections required to establish communication between the radio modem, acting as the DCE, and the PC, acting as the DTE.
SATELLINE-M3-TR1 User Guide, Version 1.4 o DTE is an abbreviation for Data Terminal Equipment o DIR column below denotes the direction of the signal: "IN" is from DTE to the radio modem, "OUT" is from the radio modem to the DTE. Port 1 complies always with the RS-232 standard. Port 2 can comply either with the RS-232, LVTTL, TTL or RS-422 standards. The interface type is set at the factory according to the customer order. The user can set the Ports ON/FF afterwards in the programming mode.
SATELLINE-M3-TR1 User Guide, Version 1.4 MODE = operational mode. When the MODE-line is connected to ground (GND), the radio modem enters the Programming Mode which is used to change the settings of the radio modem (i.e. configuration, set-up). If the MODE-line is not connected, the radio modem will enter the Data Transfer Mode, in which data can be transmitted and received. The Programming Mode is used only when installing a radio modem and changing the operational parameters of a network.
SATELLINE-M3-TR1 User Guide, Version 1.4 3.4 RS-485/RS-422 interface 3.4.1 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.
SATELLINE-M3-TR1 User Guide, Version 1.4 3.4.2 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.

SATELLINE-M3-TR1 User Guide, Version 1.4 4.2 Programming Mode The settings of SATELLINE-3AS-TR1 are fully configurable in Programming Mode by using a suitable terminal program. The most recommendable set-up (optional): NARS-1F interface adapter, CRS-9 cable, a power supply and the SaTerm terminal program. NARS-1F contains a switch to enable easy shifting into the Programming Mode. Other suitable terminal programs like SATEL Configuration Manager may also be used.
SATELLINE-M3-TR1 User Guide, Version 1.
SATELLINE-M3-TR1 User Guide, Version 1.4 5 RF INTERFACE The SATELLINE-M3-TR1 module has a single antenna connector with an impedance of 50 ohm. The user can change the frequency of the radio modem afterwards within the frequency range. The data speed of the radio interface depends on the chosen radio channel spacing. A channel spacing of 25 kHz enables a data speed of 19200 bps and a channel spacing of 12.5 kHz and 20 kHz enables, correspondingly, a data speed of 9600 bps.
SATELLINE-M3-TR1 User Guide, Version 1.4 5.2 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: 25 kHz 20 kHz 12.5 kHz FEC OFF -110 dBm -112 dBm -112 dBm FEC ON -113 dBm -115 dBm -115 dBm The Signal Threshold Level setting of the receiver determines a level above which the search for the actual data transfer signal is active.
SATELLINE-M3-TR1 User Guide, Version 1.4 there are many disturbances in the radio channels used. The use of the FEC-function will, however decrease the data transfer throughput of data by about 30 %. For a listing of exact delays introduced by using FEC-function. To switch the FEC-function ON in the Programming Mode, select: 1) Error correction ON NOTE! All radio modems, which are to communicate with each other, must have the same setting for FEC (ON or OFF).
SATELLINE-M3-TR1 User Guide, Version 1.4 6 TRANSPARENT DATA TRANSMISSION 6.1 Serial interface, data format The SATELLINE-3AS-TR1 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 (bits per second).
SATELLINE-M3-TR1 User Guide, Version 1.4 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.
SATELLINE-M3-TR1 User Guide, Version 1.4 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). 6.2.3 RTS-line The options for RTS-line are: 1) Ignored RTS-line status is ignored.
SATELLINE-M3-TR1 User Guide, Version 1.4 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). If the terminal device does not follow the status of the CTS-line and transmits too much data to the radio modem, the buffer will be emptied and the transmission is restarted.
SATELLINE-M3-TR1 User Guide, Version 1.4 6.3.3 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.

SATELLINE-M3-TR1 User Guide, Version 1.4 7 SETTINGS The configuration of SATELLINE -3AS-TR1 radio modems can be easily changed. Simply by connecting the Mode pin 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).
SATELLINE-M3-TR1 User Guide, Version 1.4 NOTE! To switch the radio modem back into Data Transfer Mode the MODE-pin must be disconnected from ground (GND). 7.2 Updating Firmware The Firmware can be updated in two ways: • By using terminal program. Instructions to use this method are given by request. • By using Configuration Manager (CM), which requires The SATEL Configuration Manager, a cable adapter between the module and a PC with serial port.

When creating a test connection, you can also use the Windows-based SATEL Configuration Manager, (available for free from authorised SATEL dealers or directly from SATEL Customer Support).
SATELLINE-M3-TR1 User Guide, Version 1.4 8 SW-RELATED COMMANDS AND OPTIONS 8.1 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. More information at Satel.com 8.
SATELLINE-M3-TR1 User Guide, Version 1.4 The radio modem will acknowledge all commands by returning an "OK" (command carried out or accepted) or the requested value, or an "ERROR" (command not carried out or interpreted as erroneous) message. 8.4.1 Changing parameters using the SL-COMMANDS The controlling terminal device can change the configuration settings of a radio modem. This is accomplished with the help of SL-commands, which can be used during data transfer. SLcommands can be used to change e.g.
