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).

3.4.1. Tx Mode
The available Tx modes are :
• 4.125ms Tx / 4.125ms Rx,
• 5s Tx /5s Rx
• or normal operation
3.4.1.1. Permanent Mode 4.125ms/4.125ms

3.4.1.3. Mode normal
In normal operation, the MRAD follows a normal radio cycle, its behavior being either a
wayside or carborne equipment. However, this mode is not available for the tests.

3.4.1.4. Configuration of the messages – permanent Tx mode
The messages which are emitted are a sequence of 0101…..01.
3.4.1.5. Configuration of the spread sequence
There are four spread sequences :
Sequence 0 (boot frame sequence) :
1100-1110-0111-1011-0011-1011-0110-0100-1100-0101-1111-1011-1010-0011-0101-0000-0100-

The sequence used in permanent Tx mode (both 4.125ms/4.125ms and 5s/5s) is the
sequence 0 (boot frame sequence).
3.4.2. RF Switch
The MRAD has two RF outputs RFA1 and RFA2 that may be selected thanks to this RF
switch.
3.4.3. Power levels
The available power levels are :
• P0 : 27.5 dBm,
• P1: 17.5 dBm,
• or P2 : 7.5 dBm
The P1 and P2 power levels will be redefined according to the results of the tests and to
the antenna configurations.
3.4.4. Frequencies
The available frequencies channels are : 2408 MHz, 2416 MHz, 2424 MHz, 2432 MHz,
2440 MHz, 2448 MHz, 2456 MHz, 2464 MHz, 2472 MHz.

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.
