3. Installation 3.1 Hole pattern (mm) The reader has four holes of 5.5 mm diameter in its cover for fastening. Figure: Underside of RRUI 4 with fastening holes Caution! Prior to installing, read the safety instructions at the start of this manual! 3.2 Selecting the installation site Pay attention to the unit's degree of protection when selecting the installation site. The standard version (IP 40) of the reader is only designed for usage indoors.
4. Software For test purposes the reader can be operated using the demo software on the CD supplied. This software includes all the reader's functionality. For integration in enterprise resource planning systems, there is a DLL file on the CD for programming custom routines. 4.1 System requirements To ensure correct operation using the software on your PC/laptop, your PC/laptop should meet the following minimum requirements: 4.
4. Software Figure: Installation, select Start menu folder In the next dialog box, define whether the setup is to create a desktop icon and an icon on the quick start toolbar.
4. Software A summary of the installation tasks is then displayed. Start the installation process by clicking the “Installieren” (Install) button. Figure: Installation, summary of the installation tasks “Installation durchführen” (Install) 4.3 Operation The test software “ReaderStart” for the RRUI4 is described in the section that follows.
4. Software The computer controls the reader via one of the available interfaces and receives over this interface the EPCs and data from the tags read. To read from an EPC tag, the reader emits an RF carrier via the active antenna and in this way supplies the tag with power. If the information on the tag is now to be read, a connection to the tag is established. For this purpose the tag is selected from a possible number of tags (singularisation).
4. Software 4.3.3 Establishing connection The “Verbindung” (Connection) tab contains all controls for establishing a connection to the reader. Depending on the unit, it is possible to establish a connection via RS 485 or RS 422, via USB or via Ethernet. 4.3.3.1 “ComPort” group box The serial interface is used for the communication with the reader via RS 485 or RS 422. The RS 485/RS 422 interface card supports the standard data rates of the serial interface on a PC.
4. Software 4.3.4 Konfiguration (Configuration) On the “Konfiguration” (Configuration) tab it is possible to set all the RF parameters for the reader as well as to set the parameters for the communication interfaces. It is also possible to read and write the licence key for the reader on this tab. If a connection has been established to the reader, the settings in the reader are read when the “Konfiguration” (Configuration) tab is opened.
4. Software 4.3.4.1 “HF-Einstellungen” (RF settings) group box In this group box the radio frequency parameters, such as the transmission power, transmission channel (EU only) and the spectrum can be set. The applicable standards in the related approval region are to be observed when setting the transmission power. Note To operate the reader in accordance with the related national standards, the antenna gain and the cable attenuation must be taken into account in the transmission power setting.
4. Software In the European approval area, the radiated power must not exceed 2 W ERP. This figure refers to a half-wave dipole. The relationship shown below exists between an isotropic radiator (dBi) and a half-wave dipole. GHW = Gisot - 2.14 dB GHW ... Gain referred to half-wave dipole Gisot ... Gain referred to isotropic radiator in dBi If the gain of the antenna is referred to the polarisation of a circular isotropic antenna (dBic), the linear gain of the antenna is 3 dB lower.
4. Software The order with which the channels are to be searched using LBT can be defined with the aid of the selection of the preferred channels. The channels selected here are searched first in ascending order. If a spare channel is not found in the preferred channels, the remaining channels are searched. In the USA the RF power connected at the antenna input is related to a minimum number of channels used.
4. Software 4.3.4.2 “IO-Modul-Einstellungen” (IO module settings) group box The reader is supplied either with an Ethernet or RS 485/422 interface depending on its features. The configuration of the interface can be adapted to the application using this group box. Note Incorrect settings can result in an interruption of the connection to the reader. The settings on readers without USB can only be reset using an interface that matches the configuration.
4. Software 4.3.4.3 Default configuration The default configuration includes all the settings for the RRUI4 as supplied. - I/O module Autodetect o 1 start bit RS 485/422 8 data bits No parity 1 stop bit 115200 bits per second - o Ethernet DHCP o Network name RRUI4_xxxx (xxxx ... seq.
4. Software 4.3.5 Test Gen2-Funktionen (Test Gen2 functions) This tab makes it possible to test the individual reader functions. This includes, along with the functionality in accordance with the EPC-Gen2 standard, e. g.: reading individual tags, writing tags, setting passwords, also the measurement of the temperature inside the reader, as well as the selection of the antenna.
4. Software 4.3.5.2 “Schreibe EPC auf einzelnen Tag” (Write EPC to an individual tag) group box The figure below shows the tab after successfully reading tags: Figure: The “Test Gen2-Funktionen” (Test Gen2 functions) tab with tags read There are two ways of writing a tag's EPC in this group box. The first is to change an existing tag or to write to any tag in the field.
4. Software To change an existing EPC, the EPC must be selected in the “gelesene EPCs” (EPCs read) box. The EPC is copied to the editable “EPC” box using the “übernehme EPC” (Copy EPC) button. There the code can be changed either manually or using the “auto-inkrement” (Auto-increment) function; the latter function increases the EPC by 1 each time the code is written successfully to a tag. The “Schreibe EPC” (Write EPC) button transfers the number from the EPC box to the selected tag.
4. Software pwd-write Permalock Description 0 0 Area can be written with and without password 0 1 Area cannot be locked, but can be written with and without password 1 0 Area can only be written with valid password 1 1 Area cannot be written Table: Lock bit functionality After the definition of the functionality, this configuration is written to the tag by clicking the “Lock für Tag” (Lock for tag) button.
4. Software EPCs read Figure: “Test Lesefunktionen” (Test read functions) The largest part of the tab is taken up by the “gelesene EPCs” (EPCs read) box. This box contains a table that displays each tag read.
4. Software If there is a very large number of tags in the field, the reader may take a very long time to singularise and read the EPCs on the tags. In such a case the software may end the read process with a timeout. In the “Readtimeout” (Read timeout) box you can define how long the software waits for a reply from the reader before the read command is declared invalid and the software outputs an error message. This time is entered in seconds and can be a maximum of 99 seconds.
4. Software By selecting the “Daten in Log File schreiben” (Write data to log file) check box the data from the status box are saved in the file “log.txt” in the program folder. 4.3.7 Echtzeituhr (Real-time clock) Here the reader's real-time clock can be read and set. Click the “Zeit lesen” (Read time) button to read the RTC from the reader and display it in the “Uhrzeit” (Time) and “Datum” (Date) fields. The time can be set by manually entering the time in the “Uhrzeit” (Time) and “Datum” (Date) fields.
4. Software Figure: Changing font Here the format of the font for the EPC field on the “Test Lesefunktionen” (Test read functions) tab can be changed. It is possible to improve the legibility of the read results on the monitor even from larger distances by increasing the size of the font. 4.3.9.4 Hilfe (Help) The “Hilfe” (Help) menu contains the Info..., Reader Info and Firmwareupdate (Firmware update) commands.
