Functional Description 10/2003Operating Instructions SRIF 2002Page 14 of 333.1 Radio transmissionThe SRIF 2002 comprises all necessary functions for the transmission of digitaldata in the 5.8 GHz range in transmit and receive mode. It is possible to set 127frequencies (channels) independent of each other. The channels can either beprogrammed via an additional asynchronous interface (UART protocol: 4800 Baud;8N1) or set via 7 binary-coded parallel control lines. The parallel setting always haspriority, i.e. a serial programming is only possible if the parallel interface isdisconnected or the word “0” is set at the parallel interface (all switches open). TheSRIF 2002 supplies an analog RSSI signal.The SRIF 2002 operates in the half duplex mode. The SRIF 2002 is in the receivemode as a standard. As soon as any transmission data are applied to the datainput (TXD) and the control signal pin2 is set to TX, the module switches to thetransmit mode and transmits the data.Figure 2: Schematic representation of the radio transmissionOperating modes of the SRIF2002:● Receive mode The receive mode is the normal operating state ofthe module.● Transmit mode The module automatically changes into thetransmit mode when a valid signal has beenreceived via the UART and after the completion ofa just received block via the radio path.● Stand-by mode The stand-by mode is activated at wrongparameterization.TxDRxDSRIF 2002 SRIF 2002 TxDRxD5.8 GHz ISM band
10/2003 Functional DescriptionOperating Instructions SRIF 2002Page 15 of 33The SRIF 2002 communicates via a serial asynchronous interface(UART protocol). The transfer rate has to be preset by the user. Transfer rates of9600, 19200, 38400, 57600 and 115200 can be set via the quadruple DIP switch ofthe SRIF 2002 (see Figure 1, page 11). Data communication is always 8E1 (8 databits, even parity, 1 stop bit).3.2 Parameterization via the parallel interfaceThe SRIF 2002 has to be parameterized via the parallel interface, for example if itis 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 asynchronousserial interface (UART protocol: 4800 baud; 8N1 (see Chapter 3.3 Serialparameterization, page 17).The following settings have to be carried out:Baud rate settingThe 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 setting8-pole plug-in connector Molex 53261-0890Connector BPinDescriptionGND(Pin 1)Reference potentialA0,..., A6(Pin 2,..., Pin8)Digital inputs for the parallel channel setting4V CMOS level binary-coded A0 = 20 and A6 = 26(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 linkmodule.
Functional Description 10/2003Operating Instructions SRIF 2002Page 16 of 33The coding switch to be connected short-circuits the selected address lines withthe reference line (inverse logic !).Due to the missing eighth address line, the settings on the coding switch startingfrom 8x are interpreted as entries starting from 0x.
10/2003 Functional DescriptionOperating Instructions SRIF 2002Page 17 of 333.3 Serial parameterizationFor 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 serialinterface.The serial programming is carried out via the additional asynchronous serialinterface (UART protocol: 4800 baud; 8N1) and offers the following options forsetting or polling the SRIF 2002:• Version and setting inquiry• Channel setting• Overwriting the baud rate setting• Connecting and disconnecting the RSSI extensionThe 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 astring consisting of 4 characters. The first three characters encode the command(numeric characters only), the fourth character is always “#”. If a valid commandhas been detected, the SRIF 2002 responses - unless it is a version inquiry - withthe string sent via the RxD line (pin 4). The response is also carried out with theUART protocol 4800 baud, 8N1.NoteCommunication via the additional asynchronous serial interface is only possible ifthe 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 aftera power-on and waits for a serial channel setting. The SRIF 2002 only changes intothe receive mode after a successful parameterization.Channel settingThe SRIF 2002 operates with a frequency pattern of 1,173.23 kHz. For optimumuse of the released ISM band (5.725 up to 5.875 GHz), the frequency of5,726.0866 MHz was set for channel 1.Example: Setting for channel 04 (hex); corresponds to a frequency of5,729.6063 MHz: 035#for the frequency table, see Chapter 7 Appendix, page 31).

With the "RSSIextension" activated in the delivery state, the SRIF 2002 always raises the RSSIvoltage 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 duringthe data output.RSSI extension Data stringON 997#OFF 996#
10/2003 Functional DescriptionOperating Instructions SRIF 2002Page 19 of 33Version and setting inquiryThe SRIF 2002 responds to the command 990# (version inquiry) with its soft- andhardware-dependent version number and its current settings for channel, transferrate, status of the RSSI extension. The “Special Channels” switch (SRIF 2000:998/999) is also output to ensure compatibility with the SRIF2000. This switch hasno function for the SRIF2002.The version number lies within the range of 200 and 299. The individual pieces ofinformation are separated from each other by “,” and are contained in the responsestring in the above mentioned sequence (202,035,994,997,998#.)Example response: Data stringVersion number 202 =SRIF2002 / V02202Channel 4, 035Transfer rate 57,600, 994RSSI extension “ON” 997Special channels“OFF”:998#

10/2003 Functional DescriptionOperating Instructions SRIF 2002Page 21 of 333.5 Notes on the radio operationConditions for the radio pathA radio path usually exists between a stationary unit (e.g. SDA or TRX245) and amobile unit (e.g. MPS, HT, MDA, BA).Various physical quantities influence the signal propagation on the radio path. Inorder to achieve a radio transmission which is as interference-free as possible, thetotal of all of the physical parameters should be as good as possible. If theindividual conditions become worse, this does not immediately result in faulty radiotraffic. However, if several negative influences add up, this could result in increasedinterferences 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 selectinga high-quality antenna. Nevertheless, the fact has to be taken into account thatinterfering frequencies might also be increased. An exact examination andmeasurement 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 awayfrom each other as possible, otherwise interferences could occur. The same istrue regarding the selection of the frequencies. The greater the distancebetween the frequencies is, the less interferences occur.● Radio link modules and frequencies:When using different radio link modules or radio systems, you should makesure that they do not send on the same or a similar frequency, but that differentfrequency ranges are used; otherwise they could influence each other.
Functional Description 10/2003Operating Instructions SRIF 2002Page 22 of 33● Radio path:The radio path in open space is the most optimal one.Stationary obstacles (e.g. walls or metallic objects) limit the transmission rangeand movable or smaller objects (also humans) also influence the radio path.Since the radio transmission in this frequency range is not only carried outdirectly, but also via reflexions, other paths are also possible (multipathpropagation).

The procedure is described inChapter 3.3, page 17).ECOS products such as the MPS, the hand-held terminal, or similar products usethe serial parameterization to overwrite this switch setting.The transmitting power of the radio module can be reduced via the S4 switch.Transmitting power S4 switchFull transmitting power OFFReduced transmitting power ONPlease refer to Technical Data in Chapter 6, page 29, for the correspondingtransmitting power.The typical setting or factory setting is “Full transmitting power”.
10/2003 SettingsOperating Instructions SRIF 2002Page 25 of 334.2 Settings for the operation in the MDA / SDAFor the operation in the MDA / SDA, both an organization channel (plus stand-bychannel) and a data channel are required. The organization channel is the samefor all MDA /SDA within one spacial area.The following channel numbers are the standard / factory settings for theSRIF 2002 module:Organization channel: 68Stand-by organization channel: 41NoteNo settings can be carried out on the SRIF! The information given above is onlyrelevant for MDA applications.Due to the increased power consumption of the SRIF 2002 module, the increasedpower consumption is set for new MDAs in the operating mode “Constant currentcontrol = 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 terminalDepending on the version and the equipped firmware in the hand-held terminal, itis 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. Thishas to be taken into account when planning the installation.In the case of older firmware versions, the possible HEX-coded channels cannot beset either.The increased power consumption of the SRIF 2002 modules reduces the servicelife of the battery-operated handheld terminal.
