5. Quick guide for installation and use
This section provides a step-by-step description of the machine 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 a new
transmission station is added or the ampli er 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 amplifier defaults to the parameters set during the initial configuration
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.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the ampli er 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):
√ Full-range 90 to 250 VAC through internal connector, mains power supply with
adequate ground connection
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity
√ Connection cable kit including:
• Mains power cable
5.1.2 Connections
The main fuse can be accessed from the outside, on the rear panel. Extract the fuse
holder using a screwdriver and make sure that it is intact; replace it if necessary.
Connect a suitable dummy load with suitable dissipation power, or antenna, or the
input of nal ampli er to the RF output (see gure 9.2 - item [2]) using a 50-Ohm
coaxial cable with “N”-type connectors.
Note: When you connect the DTVC to other devices, it is necessary to strictly
follow the instructions given by the respective manufacturers, to avoid damages
or danger situations.

WARNING: Electric shock hazard. Never handle the RF output connector
when the machine is powered on and no load is connected. Injury or death
may result.
Ensure that the POWER switch on the rear panel is set to “OFF”.
Connect the mains power cable to the MAINS terminal board on the rear panel.
Note : The mains must be equipped with adequate ground connection properly
connected to the machine. This is a pre-requisite for ensuring operator safety and
correct operation.
Connect the cable with an ASI signal to the relevant connector (ASI1 or ASI2) on
the back of the machine using a 75-Ohm coaxial cable with SMA connectors.
5.2 First power-on and setup
Follow this procedure upon rst power-on and after making changes to the
con guration of the transmitter in which the ampli er is integrated.
Note : Standard factory settings are RF power output Off (Pwr OFF) and output
power set to 0 (unless otherwise speci ed by customer).
5.2.1 Power-on
Question:
The equipment is turn off?
Answer:
• When you have performed all of the connections described in the previous paragraph,
power on the ampli er using the suitable power switch on the rear panel.
Start up informations should appear brie y on the display, quickly followed by the
main readings. If RF output is disabled, these readings will be zero.
5.2.2 Frequency lock check
Question:
The equipment doesn’t work correctly?
Answer:
• Wait at least 15 seconds from the power on of DTVC, after which the PLL is
locked to working frequency. In case of PLL is not locked, LED ALARMS light
turns on and the problem is stored in ALARMS menu.

5.2.3 Power check
Question:
The equipment doesn’t work correctly at the power set up?
Answer:
• Ensure that the INTERLOCK light turns off. It indicates that no external interlock
signal inhibites the delivering power from exciter.
• Ensure that the ASI Input is performed by 75 Ohm cables with SMA
connectors.
• Check current RF output setting and enable output (if not
already enabled) following menu path SET ⇒ Power ⇒ ( xxx ).
Output power can also be set in a Pwr OFF condition; in this condition, (Fwd) output
power reading on the display will be 0 (zero), that will be delivered the moment
you switch back to Pwr ON state.
• Check output power level and set to the desired level from the Power Menu,
which you can call up by pressing these keys in the order: SET ⇒ Power ⇒ Power:
xxx %.
Set the desired ampli er output power, whereas the forward power value shown
on the display (Power: xxx %) gives actual output power reading.

6. Operating System
The exciter is controlled by a microprocessor system. Software operations may
be grouped into two broad categories: start-up and normal operation.
6.1 Using the encoder
The interaction between the user and the exciter’s control software is performed
using the encoder.
Figure 6.1
The possible operations that you can carry out on the encoder are:
• rotation: moves the cursor shown on the display; if you turn the encoder to
the left (counterclockwise), the cursor moves downwards, if you turn it right the
cursor moves upwards; it also permits to increase or diminish the parameters
(turning the encoder left diminishes the parameter, turning it right increases it)
or to select an item from a list of options.
• pushing: push the button once when the cursor is on the name of a
menu to enter in that menu, push it when the cursor is on the name of a
parameter to enter in modi cation mode (the cursor starts blinking); after the
modi cation of a parameter, push the button to keep x the new value.
Set the value by pressing the button, to save in memory you need to press OK
that causes also the exit from menu. Press ESC if you do not want saving it,
that causes the exit keeping the value unchanged; instead in Power Menu (set
=> power) simply con rm the selection and the value will be saved.
If no controls are operated during 2 minutes, the exciter returns to the default
menu.
Turn the encoder counterclockwise
to move the cursor downwards, to
decrease the value of a parameter or to choose an element from
a list of possibilities
Turn the encoder clockwise to
move the cursor upwards, to increase the value of a parameter
or to choose an element from a
list of possibilities
Push the button once to enter in the desired
menu, to enter in modi cation mode or to
con rm a choice
