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_Nicomicon.
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.

RUNNING THE PROGRAM
Once the program is running, from the main screen it is necessary to click the POWER ON
button;thescreenwilllightupandamessage"COMMUNICATIONINPROGRESS"willappear.
After few seconds, on the left side of the screen, the operating frequency will appear together
withalltheotherparameters. Ifnot, checktheCommunicationportsetting(COM1-COM2).
To change it, click the File menu and then select "set Port".

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:
