Version 3.6 2.2 Basic configuration and installation The radio modem is shipped with the following default settings (unless otherwise specifically ordered): FIXED SETTINGS DEFINED AT THE TIME OF ORDER Radio Frequency Range In accordance with Customer Order within 403-470 MHz range Channel Spacing 12.5 kHz or 25 kHz (default 25 kHz) TX Power 0.5 W or 1 W (default 1 W) Addressing RX Address OFF / TX Address OFF Serial Port ON / 19200 / 8 bit data / None / 1 stop bit for 12.
Version 3.6 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). SATELLINE-3AS SLR radio module includes 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. The radio modem contains one serial port, which is designated as Port 1 for communication.
Version 3.6 3.1 D15 connector RF1 D-15 female connector in the radio modem Direction IN is data from DTE (Data Terminal Equipment) to the radio modem. Direction OUT is data from the radio modem to the DTE.
Version 3.6 Description of pins: 1. NC Not connected. 2. TD, Transmit data. CMOS 3.3V. Signal from DTE to modem. Asynchronous serial data. 3. RD, Receive data. CMOS 3.3V. Signal from modem to DTE. Asynchronous serial data. 4. DCD. Data Carrier Detect. Output signal from modem. Goes “high” when carrier detected. 5. RTS, Request to send.. CMOS 3.3V. Signal from DTE to modem. 6. CTS. Clear to send. CMOS 3.3V. Signal from modem to DTE. 7. GPI/CFG. CMOS 3.3V. General Purpose I/O / Config Mode. 8. PWR +VDC.
Version 3.6 4 RF INTERFACE The SATELLINE-3AS SLR module has a single Antenna connector with impedance of 50 Ω. 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.
Version 3.6 4.2.1 RSSI-signal RSSI-signal (Received Signal Strength Indicator) gives an indication of the strength of the received radio signal. This signal can be used to determine the approximate signal level. The RSSI–signal can be set and read using the SL-command. 4.3 Error correction Error correction mode called the FEC-method (Forward Error Correction).
Version 3.6 5 USER INTERFACE 5.
Version 3.6 6 TRANSPARENT DATA TRANSMISSION 6.1 Handshaking lines When using the serial interface, handshaking signals can be used to control data transfer on the DATA port. For example, the radio modem can inform the DTE that the radio channel is busy, and that it is not allowed to initiate transmission. A common way of using handshaking signals is to monitor the CTS line and ignore the others.
Version 3.6 2) Data on channel CD will switch to active state only after recognizing a valid data transmission from another SATELLINE-3AS NMS family radio modem. CD will not react to interferences like noise or possible other signals. 3) Always ON CD is always in the active state. This option is usually used with terminal equipment using the CD line as an indicator of an active connection. In this case the radio modem can transmit or receive data at any time. 6.1.
Version 3.6 1) The inter-character delay will be increased by at least the time of the modem transfer delay 2) The probability of collisions on the radio path will increase. This will be especially harmful for repeater chains The default value for the Pause length is 3 bytes. 6.2.1 Data buffering in the radio data modem A synchronisation signal is transmitted at the beginning of each radio transmission and this signal is detected by another radio modem, which then turns into receive mode.
Version 3.6 7 ADDRESSING 7.1 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 SLR radio modules allow the use of individual addresses either for reception or for transmission respectively.
Version 3.6 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.
Version 3.6 Address Data Data ER R O R Data Data Address Data Reception addressing has been set OFF. Reception addressing has 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. Reception addressing has been set ON but there is no address in the data packet.
Version 3.6 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. The substation radio modem(s) will check the address and the corresponding radio modem will identify and remove the address characters.
Version 3.6 8 SETTINGS The configuration of SATELLINE-3AS SLR radio module can be easily changed simply by connecting the module to the PC and using SATEL CM or DTE. Programming is done using the serial port of the module. 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). 8.
