Réf. : Mémo : Date : 21/08/02 - 4 - Siemens Transportation Systems exclusive property 2.2. Disconnecting coaxial cables or antennas Before disconnecting the coaxial cables or the antennas, the MRAD should be powered off. 2.3. The unused RF output A 50 Ω termination must be set on any unused RF output if no antenna is connected. 3. INSTRUCTIONS FOR USE 3.1. Setting the communication parameters The communication is established with a RS232 link between the computer and the equipment via a terminal. The RS232 is accessed via the DB9 socket [Figure 1; Figure 2] on the front panel. When the terminal is opened on the computer, its parameters have to be defined in the menu Parameters/communications as following:  Ports = COM1 or COM 2 (depends on which one was put the RS connection)  Transmission speed = 9600  Bits of stop = 1  Stream control = none  Data bits = 8  Parity = none 3.1.1. Manual setting Figure 3 : Setting the communication parameters 3.2. Automatic setting The parameters can be automatically defined by opening the file config.trm (provided on a floppy on the example below).

CONFIGURATION OF THE MENU Figure 6 : Configuration of the menu Notes :  When powered on, the MRAD begins to emit with the previous parameters. If no parameter was ever entered, there is a warning : “the Tx mode is unknown” and all parameters (Tx mode, RF output, frequency, power level) must be defined.  During the RF configuration, the MRAD continues to emit.  Each new parameter is applied immediately after input. 5. DOWNLOADING A NEW FPGA CODE To download a new FPGA code, the menu 1 (“Download a new FPGA code”) has to be chosen and confirmed. Then, the FPGA code is erased and the menu waits for a programming file *.hex.
