It is possible to set 127 frequencies (channels) independent of each other. The channels can either be programmed via an additional asynchronous interface (UART protocol: 4800 Baud; 8N1) or set via 7 binary-coded parallel control lines. The parallel setting always has priority, i.e. a serial programming is only possible if the parallel interface is disconnected or the word “0” is set at the parallel interface (all switches open). The SRIF 2002 supplies an analog RSSI signal. The SRIF 2002 operates in the half duplex mode. The SRIF 2002 is in the receive mode as a standard. As soon as any transmission data are applied to the data input (TXD) and the control signal pin2 is set to TX, the module switches to the transmit mode and transmits the data. 5.8 GHz ISM band TxD SRIF 2002 TxD SRIF 2002 RxD RxD Figure 2: Schematic representation of the radio transmission Operating modes of the SRIF2002: ● Receive mode The receive mode is the normal operating state of the module. ● Transmit mode The module automatically changes into the transmit mode when a valid signal has been received via the UART and after the completion of a just received block via the radio path. ● Stand-by mode The stand-by mode is activated at wrong parameterization. Operating Instructions SRIF 2002 Page 14 of 33 10/2003 Functional Description The SRIF 2002 communicates via a serial asynchronous interface (UART protocol). The transfer rate has to be preset by the user. Transfer rates of 9600, 19200, 38400, 57600 and 115200 can be set via the quadruple DIP switch of the SRIF 2002 (see Figure 1, page 11). Data communication is always 8E1 (8 data bits, even parity, 1 stop bit). 3.2 Parameterization via the parallel interface The SRIF 2002 has to be parameterized via the parallel interface, for example if it is used in the battery adapter (BA) / ammeter or in the TRX245 of the ECOS range. This presetting can be overwritten with the help of the additional asynchronous serial interface (UART protocol: 4800 baud; 8N1 (see Chapter 3.3 Serial parameterization, page 17). The following settings have to be carried out: Baud rate setting The SRIF 2002 carries out the setting of the DIP switch after every power-on reset. See Chapter 4 Settings, page 23, for a table listing of the settings. Channel setting 8-pole plug-in connector Molex 53261-0890 Connector B Pin Description GND (Pin 1) Reference potential A0,..., A6 (Pin 2,..., Pin8) Digital inputs for the parallel channel setting 4V CMOS level binary-coded A0 = 2 and A6 = 2 (for channel numbers, see Chapter 7 Appendix, page 31; for Pin numbering, see Chapter 2 Block Diagram, page 11) 7 parallel inputs (A0 = LSB, A6 = MSB) and one reference line (GND) are used. The address lines are equipped with internal pull-up resistances at the radio link module. Operating Instructions SRIF 2002 Page 15 of 33 Functional Description 10/2003 The coding switch to be connected short-circuits the selected address lines with the reference line (inverse logic !). Due to the missing eighth address line, the settings on the coding switch starting from 8x are interpreted as entries starting from 0x. Operating Instructions SRIF 2002 Page 16 of 33 10/2003 3.3 Functional Description Serial parameterization For the use of the SRIF 2002 radio link module in the MPS, hand-held terminal, and MDA devices of the ECOS range, the channel number is set via the serial interface. The serial programming is carried out via the additional asynchronous serial interface (UART protocol: 4800 baud; 8N1) and offers the following options for setting or polling the SRIF 2002: • Version and setting inquiry • Channel setting • Overwriting the baud rate setting • Connecting and disconnecting the RSSI extension The meaning of the settings is explained in the following. The transmission of the data via the serial interface is carried out in the form of a string consisting of 4 characters. The first three characters encode the command (numeric characters only), the fourth character is always “#”. If a valid command has been detected, the SRIF 2002 responses - unless it is a version inquiry - with the string sent via the RxD line (pin 4). The response is also carried out with the UART protocol 4800 baud, 8N1. Note Communication via the additional asynchronous serial interface is only possible if the parallel interface is disconnected or the word “0” is set at the parallel interface (all switches open). With the “serial parameterization”, the SRIF 2002 starts in the stand-by mode after a power-on and waits for a serial channel setting. The SRIF 2002 only changes into the receive mode after a successful parameterization. Channel setting The SRIF 2002 operates with a frequency pattern of 1,173.23 kHz. For optimum use of the released ISM band (5.725 up to 5.875 GHz), the frequency of 5,726.0866 MHz was set for channel 1. Example: Setting for channel 04 (hex); corresponds to a frequency of 5,729.6063 MHz: 035# for the frequency table, see Chapter 7 Appendix, page 31). Operating Instructions SRIF 2002 Page 17 of 33 Functional Description 10/2003 Baud rate setting Setting the transfer rate: Transfer rate (baud) Data string 9,600 991# 19,200 992# 38,400 993# 57,600 994# 115,200 995# RSSI voltage / RSSI extension The SRIF 2002 offers two settings for the output of RSSI voltage. With the "RSSI extension" activated in the delivery state, the SRIF 2002 always raises the RSSI voltage to a level of approx. 4V if received data are output at pin 4 (RxD). If the “RSSI extension” is switched off, the RSSI level is not raised to 4 Volt during the data output. RSSI extension Data string ON 997# OFF 996# Operating Instructions SRIF 2002 Page 18 of 33 10/2003 Functional Description Version and setting inquiry The SRIF 2002 responds to the command 990# (version inquiry) with its soft- and hardware-dependent version number and its current settings for channel, transfer rate, status of the RSSI extension. The “Special Channels” switch (SRIF 2000: 998/999) is also output to ensure compatibility with the SRIF2000. This switch has no function for the SRIF2002. The version number lies within the range of 200 and 299. The individual pieces of information are separated from each other by “,” and are contained in the response string in the above mentioned sequence (202,035,994,997,998#.) Example response: Data string Version number 202 = SRIF2002 / V02 202 Channel 4, 035 Transfer rate 57,600, 994 RSSI extension “ON” 997 Special channels “OFF”: 998# Operating Instructions SRIF 2002 Page 19 of 33 Functional Description 3.4 10/2003 Serial data interface Pin assignment 10-pole plug-in connector Molex 53261-1090: Connector A Pin Type Description RSSI (Pin 1) Output analog / digital Receive Signal Strength Indicator Rx / Tx (Pin 2) Input digital Test mode switchover SerIN (Pin 3) Input digital Asynchronous serial programming interface RxD (Pin 4) Output digital Received data PWR (Pin 5) Input digital Control of the transmitting power TxD (Pin 6) Input digital Transmission data Mode (Pin 7) Input digital Test mode activation + 5V (DC IN) (Pin 8) Input Supply voltage LDI (Pin 9) Output digital Status output of the PLL frequency synthesizer GND (Pin 10) Output of the received data in the receive mode Reference potential For pin numbering in the connector, see Chapter 2 Block Diagram, page 11. Operating Instructions SRIF 2002 Page 20 of 33 10/2003 3.5 Functional Description Notes on the radio operation Conditions for the radio path A radio path usually exists between a stationary unit (e.g. SDA or TRX245) and a mobile unit (e.g. MPS, HT, MDA, BA). Various physical quantities influence the signal propagation on the radio path. In order to achieve a radio transmission which is as interference-free as possible, the total of all of the physical parameters should be as good as possible. If the individual conditions become worse, this does not immediately result in faulty radio traffic. However, if several negative influences add up, this could result in increased interferences in the radio transmission or it could completely collapse. Parameters of a radio path: ● Selection of the antennas: The type of antenna is specified for the respective device used . If it is necessary to optimize a radio path, it is possible to improve it by selecting a high-quality antenna. Nevertheless, the fact has to be taken into account that interfering frequencies might also be increased. An exact examination and measurement of the radio path is necessary for each application. ● Arrangement of the antenna: With stationary units, the antenna should be installed in such a way that an "obstacle-free" radio path can be set up, i.e. there are no fixed and, if possible, no moving obstacles in the direct radio path. ● Arrangement of several antennas: Different antennas with different radio paths should be installed as far away from each other as possible, otherwise interferences could occur. The same is true regarding the selection of the frequencies. The greater the distance between the frequencies is, the less interferences occur. ● Radio link modules and frequencies: When using different radio link modules or radio systems, you should make sure that they do not send on the same or a similar frequency, but that different frequency ranges are used; otherwise they could influence each other. Operating Instructions SRIF 2002 Page 21 of 33 Functional Description ● 10/2003 Radio path: The radio path in open space is the most optimal one. Stationary obstacles (e.g. walls or metallic objects) limit the transmission range and movable or smaller objects (also humans) also influence the radio path. Since the radio transmission in this frequency range is not only carried out directly, but also via reflexions, other paths are also possible (multipath propagation).

The transfer rate has to be preset by the user. Transfer rates of 9,600, 19,200, 38,400, 57,600 and 115,200 baud can be set via the quadruple DIP switch of the SRIF 2002. Data communication is always 8E1 (8 data bits, even parity, 1 stop bit). The SRIF 2002 carries out the setting of the DIP switch after every power-on reset. Transfer rate (baud) Switch position S3 S2 S1 S4 9,600 OFF OFF OFF 19,200 OFF OFF ON 38,400 OFF ON OFF 57,600 OFF ON ON 115,200 ON (X: Switch position irrelevant) The typical setting / factory setting is the baud rate 57,600. Note This presetting can be overwritten with the help of the additional asynchronous serial interface (UART protocol: 4800 baud; 8N1). The procedure is described in Chapter 3.3, page 17). ECOS products such as the MPS, the hand-held terminal, or similar products use the serial parameterization to overwrite this switch setting. The transmitting power of the radio module can be reduced via the S4 switch. Transmitting power S4 switch Full transmitting power OFF Reduced transmitting power ON Please refer to Technical Data in Chapter 6, page 29, for the corresponding transmitting power. The typical setting or factory setting is “Full transmitting power”. Operating Instructions SRIF 2002 Page 24 of 33 10/2003 4.2 Settings Settings for the operation in the MDA / SDA For the operation in the MDA / SDA, both an organization channel (plus stand-by channel) and a data channel are required. The organization channel is the same for all MDA /SDA within one spacial area. The following channel numbers are the standard / factory settings for the SRIF 2002 module: Organization channel: Stand-by organization channel: 68 41 Note No settings can be carried out on the SRIF! The information given above is only relevant for MDA applications. Due to the increased power consumption of the SRIF 2002 module, the increased power consumption is set for new MDAs in the operating mode “Constant current control = ON” (MDA 5 = 280 mA and MDA6 = 300 mA). Please contact your contact partner for more information. 4.3 Settings for the operation in the hand-held terminal Depending on the version and the equipped firmware in the hand-held terminal, it is possible that not all of the radio channels can be set and thus used. Limitations of the radio channels between 1 and 33 and 41 to 73 might occur. This has to be taken into account when planning the installation. In the case of older firmware versions, the possible HEX-coded channels cannot be set either. The increased power consumption of the SRIF 2002 modules reduces the service life of the battery-operated handheld terminal.
