Version 3.3 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-R1 and M3-T1 radio modules 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. The radio modem contains one serial port, which is designated as Port 1 for communication.
Version 3.3 3.1 D-15 connector D-15 female connector in the radio modem Pinout of the D-15 15-PIN FEMALE D CONNECTOR PINOUT o DTE is an abbreviation for Data Terminal Equipment o I/O 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. PIN NAME I/O LEVEL EXPLANATION 1 DTR IN TTL/LVTTL Data Terminal Ready to Power Down the radio module. Open = Normal Data Transfer Mode. Ground= Power Down; low current consumption mode.
Version 3.3 Description of pins: 1. DTR. Data Terminal Ready. When open or connected to + Voltage the unit is ready for normal transfer mode. When connected to Ground the unit goes to low current consumption mode. OFF<2.7V. ON>3V-30V. 2. Port 2. CTS. Clear To Send. TTL-Signal from modem to DTE. 3. Port 2. RD. Receive data. TTL-Signal from modem to DTE. Asynchronous serial data. 4. Port 2. TD. Transmit data. TTL-Signal from DTE to modem. Asynchronous serial data. 5. Port 2. RTS. Request to Send.
Version 3.3 4 RF INTERFACE The SATELLINE-M3-R1 and -M3-T1 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.
Version 3.3 4.2.1 RSSI-signal The 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 The error correction mode is called the FEC-method (Forward Error Correction).
Version 3.3 5 USER INTERFACE 5.
Version 3.3 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 3.3 2) Flow control The radio modem transmits data to the terminal device only when the RTS-line is active. An inactive state of the RTS-line will force the radio modem to buffer the received data. This option is used when the terminal device is too slow to handle data received from the radio modem. 3) Reception control The RTS-line controls the reception process of the radio modem. An active RTS-line enables reception.
Version 3.3 has stopped data transmission, it will take a moment for the radio modem to transmit the buffered data and switch the transmitter off. The maximum size of the 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 cleared and the transmission restarted.
Version 3.3 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. The SATELLINE-M3-R1 and -M3-T1 radio modules allow the use of individual addresses either for reception or for transmission respectively.
Version 3.3 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 RXaddress of the radio modem is identical to the address of the received data packet.
Version 3.3 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 3.3 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.
Version 3.3 8 SETTINGS The configuration of SATELLINE-M3-R1 and -M3-T1 radio modules can be easily changed simply by connecting the module to the PC and using SATEL Configuration Manager 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.
