CHAPTER 1

GENERAL DESCRIPTION

NT 250 Transmitter Exciter

INTRODUCTION

The NT 250 FM Exciter is the latest in state of the art products available from Nicom. This

Transmitter is designed with high reliability components and is intended to give many years of trouble free continuous service. This unit incorporates many features including a switching power supply and a PLL frequency synthesizer.

The latest SMD technology has allowed to make a more compact unit (only 3 rack spaces) and at the same time a very light unit (only 32 lbs).

INSTALLATION

After unpacking the module, check for any mechanical damage or loose parts inside.If there is any transportation damage, inform the supplier immediately and do not put the module into operation.

The voltage is applicable from 100 to 240 Volts without needing any change.

Ensure that the station’s ground system connections have a ground resistance of less than 5 ohms. The equipment’s rack or cabinet must be effectively grounded.

Check that the transmitter’s main switch is off.

Connect the power cord to the AC plug.

STARTING PROCEDURE

Connect the antenna cable to the ‘N’ connector on the back of the unit. The antenna system must be set up to operate at the transmitter’s working frequency.

ATTENTION

Antenna matching is extremely crucial for FM transmitters. Operate this unit only after verifying good matching. Mismatching will decrease the communication distance and unduly stress the semiconductors.

Turn on the transmitter.

After 1 or 2 seconds the green LED “PLL LOCK” should turn on. This indicates that the frequency is locked on the programmed value.

After 1 more second the “RF ENABLE” green LED will come on. This indicates that RF power is being delivered to the output connector on the back.

Now you can input modulation. For MONO operation connect your signal to the XLR connector following the connecting instructions printed on the back of the transmitter and then regulate the input level with the apposite trimmer. For stereo input, use the BNC connector labeled “MPX”.

Regulate the audio with the apposite trimmer.

Note:Be sure that the modulation level is close to but not more than 75KHz. 75KHz is 100% modulation. Lower modulation level will decrease the S/N value while over-modulation (>100%) will cause distortion at the receiver and it is against current regulations.

REMOTE CONTROL FEATURE

The NT 250 is equipped with a 9 pin RS 232 connector that allows all the mains telemetry functions. The software is supplied with the unit and with this CD rom it's possible to monitor and to change the main parameters ot the NT 250 on the computer's screen.

The NT 250 is also supplied with the interlock connector that allows to switch the power on and off simply by grounding the inner conductor of the BNC.

NOTE:

The CD Rom supplied contains the remote control software of the NT 250.

REMOTE CONTROL SOFTWARE

INSTALLATION

The NT 250 comes with a Serial port RS 232. This port allows a Bi-Directional remote control of the unit from a PC.

INSTALLING THE SOFTWARE

1. Insert the NT 250 CD-ROM into the CD drive.

2. Run Setup.exe file found in the main folder of the CD-ROM. The installation will continue automatically asking only for the name of the folder of the hard drive where the program will be installed. It will be necessary to reboot the computer.

3. Once installed, the Tx_Nicom program icon can be recalled by clicking : Start - Programs -

Tx_Nicom icon.

CONNECTING THE NT 250

The NT 250 is equipped with a Serial Port (RS232) in the rear panel. To connect the computer with the NT 250 we recommend standard serial cables Pin-to-Pin; the lenght of the cable must stay within 60 feet.

REMEMBER TO CLOSE THE PROGRAM BEFORE REMOVING THE CONNECTING CABLE

Page 3


RUNNING THE PROGRAM

Once the program is running, from the main screen it is necessary to click the POWER ON button; the screen will light up and a message" COMMUNICATION IN PROGRESS" will appear.

After few seconds, on the left side of the screen, the operating frequency will appear together with all the other parameters. If not, check the Communication port setting (COM1-COM 2).

To change it, click the File menu and then select "set Port".

The other parameters shown on the screen are the following:

1. Temperature in Celsius ( remember that Farheneit is Celsius x 1.8 + 20)

2. Lock Indicator showing that PLL circuit of the unit is locked

3. On the Air

4. RF Forward

5. RF Reflected showing that the unit is transmitting giving the amount of Watts radiated giving the amount of reflected power

On the right side of the screen there are four buttons that allow to modify the parameters: a. Send Button to be used after a change of frequency is made b. Set Frequency allows the change of frequency by clicking the new frequency on the keyboard on the left side of the screen c. Disconnect d. RF On allows to disconnect the system turns up and down the power

NT 250 PROGRAMMING

Connect a 50 ohm load or 50 ohm antenna to the RF output, connect the equipment into a mains supply (100÷240 VAC). The equipment is factory pre-set to 50 W.

Switch ON the power and the yellow V POWER LED will light.

The Display will show:

WAIT

PROGRAM

SETTING

After 3 seconds the green PLL LOCK led will light and the Display will show an increasing bar. After a further 5 seconds the green ENABLE will light and there will be output power.

WAIT

PROGRAM

At this point the Display will show the next parameter:

• Level Modulation (MOD > );

• Forward Power (FRW 50.0W);

• Reflected Power (RFL 0.4W).

MOD >

SETTING

PROGRAM

FRW 50W RFL 0.4W

SETTING

The default frequency is 98.000 MHz.

To display the frequency push the SETTING key.

In order to display the parameter push the SELECT key.

Display Password

The Password mode is factory set to enable, and is not possible change this setting.

The default password is 1 2 3.

The way for changing the password is the following:

• Press the PROGRAM key for 3 seconds;

PASSWORD PROGRAM

0 1 2 3 4 5 6 7 8 9

SETTING

• Press the PROGRAM key to move the underscore character position at the required digit, and press the SETTING key to confirm the digit.

0 1 2 3 4 5 6 7 8 9

PROGRAM

SETTING

Repeat the same for the two remaining digits.

PROGRAM

0 1 2 3 4 5 6 7 8 9

SETTING

• If the password is correct press the SETTING key to confirm, otherwise press the PROGRAM key to select again.

CONFIRM (Y/N) ?

N=SEL. Y=SET.
