4. Unpacking
The package contains:
1 TEX500-LCD or TEX1000LIGHT
1 User Manual
1 Mains power cable
The following accessories are also available from Your R.V.R. Dealer:
• Accessories, spare parts and cables
4.1 General Description
TEX500-LCD and TEX1000LIGHT are compact FM transmitters manufactured by
R.V.R. Elettronica SpA for audio radio broadcasting in the 87.5 to 108 MHz band
in 10kHz steps, featuring adjustable RF output up to 500 and 1000 W, respectively,
under 50 Ohm standard load.
TEX500-LCD and TEX1000LIGHT have been designed for installation in a 3HE
box for 19” rack.
These transmitters incorporate a low-pass lter to keep harmonics below the limits
provided for by international standards (CCIR, FCC or ETSI) and can be connected
directly to the antenna.
Two major features of TEX500-LCD and TEX1000LIGHT are compact design and
user-friendliness. Design is based on a modular concept: the different functions
are performed by modules that, for the most part, are connected through male and
female connectors or through at cables terminated by connectors. This design
facilitates maintenance and module replacement.
The RF power section of TEX500-LCD uses two MOSFET modules delivering up
to 300W output power each, whereas TEX1000LIGHT features three MOSFET
modules with up to 350 W output power each.
Operating frequency stability is ensured by a temperature-compensated reference
oscillator and is maintained by a PLL (Phase Locked Loop) system. The transmitters
will go into frequency lock within 30 seconds after power-on.
TEX500-LCD and TEX1000LIGHT can operate throughout the frequency bank
with no need for calibration or set-up.
An LCD on the front panel and a push-button board provide for user interfacing
with the microprocessor control system, which offers the following features:
• Output power setup.
• Operating frequency setup.
• Power output enable/disable.
• Power Good feature (User-selectable output power alarm threshold).

TEX500-LCD & TEX1000LIGHT
• Measurement and display of transmitter operating parameters.
• Communication with external devices such as programming or telemetry
systems via RS232 serial interface or I2C.
Four LEDs on the front panel provide the following status indications: ON,
LOCK, FOLDBACK and RF MUTE; two yellow LEDs indicate power supply unit
malfunction.
The exciter management rmware is based on a menu system. User has four
navigation buttons available to browse submenus: ESC (Sect.6.1 - [6]), , ,
and ENTER (sect. 6.1 - [9]).
The rear panel features the mains input connectors with a mains voltage switch
(see Sect. 6.2 - [30]) to select the appropriate mains input voltage, as well as audio
input connectors and RF output connector, telemetry connector, protection fuses
and two inputs for signals modulated onto subcarriers by suitable external coders,
such as RDS (Radio Data System) signals commonly used in Europe.

5. Installation and conguration procedure
This section provides a step-by-step description of equipment installation and
conguration procedure. Follow these procedures closely upon rst power-on
and each time any change is made to general conguration, such as when anew
transmission station is added or the equipment is replaced.
Once the desired conguration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial conguration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and rmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When conguring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the exciter and immediately inspect it for transport damage. Ensure that
all connectors are in perfect condition.
Provide for the following (applicable to operating tests and putting into service)
√ Single-phase 230 VAC or 115 VAC (-15% / +10%) mains power supply with
adequate earth connection
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity (500W for TEX500-LCD or 1000W for TEX1000LIGHT as a
minimum)
√ Connection cable kit including:

When setting input sensitivity, please consider that the default menu reports
instantaneous modulation level and an indicator provides a 75 kHz reading. To
ensure correct adjustment, apply a signal with the same level as user’s audio
broadcast maximum level and then adjust using the trimmer until instantaneous
deviation matches the 75 kHz reading.
To set subcarrier input levels, you may use the same procedure and option “x10”
available in the Fnc menu. With this option, modulation level is multiplied by a factor
of 10, which means that default menu bar meter reects a 7.5 kHz deviation.
A special menu with separate indications of Left and Right channel levels and
relating indicators of nominal levels for maximum deviation (75 kHz) is provided.

5.3 Operation
NOTE: For better clarity, only the typical screens of TEX1000LIGHT are reported
below. TEX500-LCD screens look the same except that full scale values are
different.
1) Power on the exciter (sect. 6.1 - [11]) and ensure that the ON light turns on
(section 6.1 - note [1]). Equipment name should appear briey on the display,
quickly followed by modulation and forward power readings (Menu 1), provided
that the exciter is delivering output power.
Menu 1
1b) To modify power level setting, hold down the ENTER button until opening
the power setup menu.
The edit screen will look like this:
Menu 2
Next to SET indication, a bar provides a graphic display of preset output power.
The lled portion of the bar is proportional to set power level.
Example
100% output power Full bar
≅1000W output
(mod.TEX1000LIGHT)
≅500W output
(mod.TEX500-LCD)
50% output power Half-full bar
≅500W output
(mod.TEX1000LIGHT)
≅250W output
(mod.TEX500-LCD)
25% output power Quarter-full bar
≅250W output
(mod.TEX1000LIGHT)
≅125W output
(mod.TEX500-LCD)
The bottom line provides instantaneous power reading (997W for TEX1000LIGHT
shown here); press button to increase level, press to decrease it. When
you have achieved the desired level, press ENTER to conrm and exit the default
menu. Please note that the setting is stored automatically; in other words, if you
press ESC or do not press any keys before the preset time times out, the latest
power level set will be retained.

(500W for TEX500-LCD or 1000 W for TEX1000LIGHT); however, never exceed
the specied power rating.
NOTE: If power is set to 0 W in the Power Setup Menu, the INTERLOCK OUT
contact (sect. 6.2 - [22]) is activated and any external appliances connected to
it are immediately inhibited.
Next, you can review all operating parameters of the equipment through the
management rmware.
Normally, the equipment can run unattended. Any alarm condition is handled
automatically by the safety system or is signalled by the LED indicators on the
panel or by display messages.
NOTE: Standard factory settings are output power set to upper limit (unless
otherwise specied by customer) and OFF.
5.4 Management Firmware
The equipment features an LCD with two lines by 16 characters that displays a
set of menus. Figure 5.2 below provides an overview of equipment menus.
The symbols listed below appear in the left portion of the display as appropriate:
(Cursor) - Highlights selected (i.e. accessible) menu.
(Filled arrow) - Editable parameter marker. This symbol appears in menus that
take up more than two lines to aid browsing.
(Three empty arrows) - Parameter is being edited.
(Empty arrow) - Current line marker; the parameter in this line cannot be
edited. This symbol appears in menus that take up more than two lines to aid
browsing.

 Modies Power Good threshold for forward power. The Power Good
rate is a percent of equipment rated power (500W for TEX500-LCD and
1000 W for TEX1000LIGHT), not of forward output power. This means
that this threshold set at 50% will give 250 W and 500 W, respectively,
regardless of set power level. The Power Good feature enables output
power control and reporting. When output power drops below set Power
Good threshold, the equipment changes the state of pin [7] of the DB15
“Remote” connector located on the rear panel (gure 6.2 - [28]).
PgR Modies Power Good threshold for reected power. The Power Good
rate is a percent of equipment rated power (50W for TEX500-LCD
and 100 W for TEX1000LIGHT), not of reected output power. This
means that this threshold set at 2.5% and 5%, respectively, will give
