1. Note that using a Tx to RX internet link is not sure If you choose to place the ftp site on the Rx station the system administrator will surely ask you to define a set of internet IP addresses that you want to allow access to this ftp site Naming ftp site IP address A problem can be encountered if the ftp site is running on Rx station User should use localhost or explicit IP address to name ftp IP address localhost must not be used The same field will be used for Rx station and Controller station to reach ftp site If localhost will be applicable for Rx station it will not be for Controller station if controller is not running on the same host as Rx station Do not use alphabetical DNS naming for any IP addresses Choose numerical naming Using USB Serial Converter More and more PCs are provided without native UART based serial link Titan digitizers use RS232 serial link for communications Moreover using native serial links gives some overrun problems Some bytes are sometimes lost making then a lack in data stream These two problems can be solved using USB Serial converters Contact agecodagis libertysurf fr to purchase such devices You will find here instructions to install usb serial converter These instructions apply for linux OS Using Windows OS is not recommended because of its instability The two ones needed are keyspan o gz and usbserial o gz Usually the containing dir is lib modules VERSION kernel driv2. a double loop scheme C Sender Stations D Receiver Stations Controller Stations Ftp Site The first loop is safe This is the link between Sender and Receiver stations The Internet loop may be temporarily unsafe Data are retained on the Receiver station hard disk as long as the media size can do it When the max size is reached oldest data are automatically destroyed Receiver stations regularly try to get ftp site connection If the connection is impossible at one time a further try will be made in a near future If the ftp site is unreachable for 3 days a warning mail is sent TCP IP Links Here are the different links used for communications For clarity the following scheme only shows one instance of each kind of station Commands we Socket IP Port link P Ftp link CI Sender Stations Receiver Stations Controller Stations Ftp Site IP and Ports Addressing Sender stations Fixed IP address is not required for sender stations within sure loop Only the two IP ports numbers have to be assigned accordingly with those defined in the attached receiver station Every sender station sending data to the same receiver station needs to use the same IP ports The first one is the Data IP port used to send real time data from sender stations to receiver station The second IP Port is used to exchange configuration digitizer commands between receiver and sender station These two IP ports ca
