The recommended terminal program is RealTerm. It is Open Source Software and can be downloaded from the webpage http://sourceforge.net/projects/realterm. Install the program on your PC. 8.1.
® SYMEO LPR LPR-1D Product Documentation If you want to use a longer serial cable you have to reduce the baud rate of the LPR-B station. Ask the Symeo Service for detailed information. Typical values for the data rate for different length of the serial cables are: Max. baud Max. Length of RS232 rate cable 9.600 152 m 19.200 15 m 57.600 5m 115.200 <2 m 8.
® SYMEO LPR LPR-1D Product Documentation In two tabs you have to change the settings: Tab Display: - Choose Display As Ansi - Extend the Rows from 16 to 30 Tab Port: - Change the Baud to 115.200 - Choose the right COM port - Click On Open Depending if you are connected to a transponder or a base station characters may appear in the window. If you are connected to a transponder a lot of “t” characters appear.
® SYMEO LPR LPR-1D Product Documentation If you press button “1” (configuration menu) and button “6” (setup) then you can get more detail about the system. Click maybe on freeze to enable the scroll bar and scroll up to setup menu. Note the point f……..fsk channel. With the character “x” you return to the main menu.
® SYMEO LPR LPR-1D Product Documentation 8.5.1 LAN Settings of your PC First you need to disconnect your PC from your network to avoid trouble when changing the IP address of your computer. Now you connect the LPR-B station via an Ethernet cable with your PC. If you are not in the same net as the LPR-B station you have to change temporary the network settings of your PC. Both IP-address must be in the same network, i.e. the first three fields of the IP-address must match.
® SYMEO LPR LPR-1D Product Documentation You should get a reply from the LPR-B station with the fixed IP-address 192.168.1.99 If the connection failed probably your firewall settings of your PC are set to restrictive or the IP-address of the LPR-B station is probably not 192.168.1.99. Please check the settings. Compare also the hint in chapter 8.5.1. If you have changed the IP address without bearing in mind the IP address the IP-address could be detected with the program NetworkScanner. 8.5.
® SYMEO LPR LPR-1D Product Documentation In both cases you can click inside the window and press the button 3. If nothing appears than there is something wrong with the connection between the LPR-B station and your computer or the station has no power. Normally it shows you some system information: In the upper line is written the System Address: The system address indicates if the station is a transponder or a base station and which group ID the station has.
® SYMEO LPR LPR-1D Product Documentation If you do not get access to the LPR-B station check if the port is open. The port for the parameterization is 3045 per default. But it might be possible that you have changed it or did not open it (see chapter 8.5.5). 8.5.5 Web Interface If you can “ping” the IP-address of the LPR-B station but do not get data (either via the parameterization port or the binary port or both ports) you have to check the settings on the web page of the LPR-B station.
® SYMEO LPR LPR-1D Product Documentation Scroll down to the section: Serial-to-Ethernet: Here you enter the connection type for the parameterization port (ttyAM1) and the binary port (ttyAM2). Both ports should be not disabled. Choose the right connection type and enter the data port. The data port is per default 3045 for the parameterization port and 3046 for the binary port. If you have made changes click on “Upload changes” and then on “Reboot system”.

A small label on the backside of the antenna indicates the horizontal and vertical alignment. 4) For a distance measurement always two stations are involved. It has to be a transponder unit and a base station unit. Make sure that never two base stations or two transponders a measuring with each other.
® SYMEO LPR LPR-1D Product Documentation If you use LPR-B stations with and without TCP/IP jumpers are set differently. To make the parameterization via serial connection jumpers has to be changed (only the both lower pictures are set for configuration the LPR-B station via the serial cable). 4) Overwrite the configuration with the program LPR 1D wizard for all stations.
