1. Introduction
Most homes still use coaxial cable as a way to distribute TV signals from the aerial to the
various TVs within the property. The new MOD200 modulator allows you to make the best
out of this set up and use it to distribute your home CCTV through this same coaxial cable
network.
It works by allowing the HDMI output of a DVR (or other equipment such as a Satellite box)
to be converted into a digital RF signal or “Digital TV channel” so you can distribute it
around a home and watch it on any TV just like it was a real digital TV channel.
The MOD200 produces a high quality 1080p picture far superior to an analogue modulated
signal and as all new TVs contain a digital tuner it’s a great way to distribute CCTV in a
home or a commercial building via coaxial cable.
The HDMI input to the MOD200 also carries sound alongside the video, so any connected
TVs will also be able to playback sound from the DVR or other device too.
The MOD200 is also extremely useful for distributing the output from DVRs to multiple
“TVs” in commercial environments such as pubs or clubs as it can all be done over low cost
coax using an off-the-shelf RF distributor.
The unit is configured to run out of the box as settings have been defaulted to UK
specifications, with low insertion loss of -3dB and wide output attenuation capability down to
-30dB making it particularly versatile over shorter distances. However if you do need to
make other changes there is an Advanced Menu section for advanced users.

2. User Information
a. The modulator must be installed in a clean, dry environment where it will not be
exposed to high temperatures, moisture or excessive dust.
b. Do not touch the modulator or any of its connections with wet hands.
c. Ensure the power is switched off if the modulator isn’t used for a long period of
time.
d. There are no user serviceable parts in the modulator and opening or attempting to
repair the product will void the warranty.
e. Only use the power supply originally supplied with the product.
f. Do not install or use the device if the power cable is damaged.
g. Ensure the power to the modulator is switched off when connecting or removing
cables.
h. In general, it is not necessary to re-configure the modulator to generate a signal
compatible with a UK digital terrestrial television receiver. UK modulation
parameters are the default.
Special Note
The MOD200 has to process and digitise the HDMI input from the DVR and this creates a
small delay or “latency” on the output, typically in the region of 1.5 seconds. This means that
the TV picture will be approximately 1.5 seconds behind what the source output is actually
doing. This is similar to the latency effect that you get with IP camera systems.

5. Typical Installation (Using one HDMI input)
Below is a typical example of how the MOD200 may be installed into a residential property.
Although the MOD200 has a built-in combiner this will not provide power if a “Masthead”
amplifier is being used so an external DC combiner such as the AER190 which will pass DC
power to the “Masthead amplifier” must be used in such circumstances. See section 7.
Example of combining a single modulated channel to aerial output for distribution
Step 1: Connect the DVR (or other video equipment) to the HDMI input on the
MOD200.
Step 2: The MOD200 merges the TV aerial signal via the RF input with the
modulated HDMI signal from the DVR to produce a combined RF output that
can be connected to an RF distributor for viewing on multiple TVS at the
property.
Step 3: The final step is to re-tune all the TVs to discover and view the video images
as digital TV channels. These channels are identified by their LCN number.

6. Cascading MOD200s (Using multiple modulators)
On larger commercial or retail installs such as bars, shopping centres and hotels you could
connect multiple units together to enable a number of devices to be viewed as separate digital
TV channels. This could be used to distribute sports channels around a pub or information
channels to hotel rooms. Up to five MOD200s can be connected using the method shown
below.
Example of combining two modulated channels with an aerial output for distribution
Step 1: Connect the DVR (or other video equipment) to the HDMI input on the
MOD200.
Step 2: The MOD200 merges the TV aerial signal via the RF input with the
modulated HDMI signal from the DVR to produce a combined RF output that
can be connected to the RF in on the second MOD200 that will combine the
HDMI signal from the Sky box. The RF out from the second MOD200 then
connects to the RF distributor for viewing on multiple TVS at the property.
Step 3: When introducing a second MOD200, you will need to change the LCN and
Channel Number (RF Frequency) in this and subsequent MOD200s cascaded,
so they are uniquely identified.
Step 4: The final step is to re-tune all the TVs to discover and view the video images
as digital TV channels. These channels are identified by their LCN number.

7. Installation when using a Masthead Amplifier
Although the MOD200 has a built-in combiner you may encounter problems where a
“masthead” amplifier powered remotely up the coaxial cable is being used, as the MOD200
internal combiner will not pass this power. We recommend that you use an external DC
combiner such as the AER190 which will pass DC power to the “Masthead amplifier”. If the
“Masthead” amplifier is being powered locally (to the amplifier) then the AER190 will not be
necessary. If the amplifier has its own up the coax PSU then this can be inserted between the
amplifier and the RF IN of the first MOD200.
Example of combining multiple MOD200s with an aerial output for distribution using
an AER190 DC Combiner when a Masthead Amplifier is being used.
Step 1: Connect the DVR (or other video equipment) to the HDMI input on the
MOD200. Fit the 75 Ohm Terminator supplied to the MOD200 RF in.
Step 2: The MOD200 merges the TV aerial signal via the RF input with the
modulated HDMI signal from the DVR to produce a combined RF output that
can be connected to the RF in on the second MOD200 that will combine the
HDMI signal from the Sky box. The RF out from the second MOD200 then
connects to the AER190 DC Combiner, combining that and the TV aerial
input, then into the RF distributor for viewing on multiple TVS.
Step 3: When introducing a second MOD200, you will need to change the LCN and
Channel Number (RF Frequency) in this and subsequent MOD200s cascaded,
so they are uniquely identified.
Step 4: The final step is to re-tune all the TVs to discover and view the video images
as digital TV channels. The channels will be identified by their LCN number.

9. Menu settings that may require change
The MOD200 has been designed for use in the UK. Therefore the standard default parameters
are those for the UK and will only need changing as per details below. They are highlighted
in bold and asterisked in the menu structure chart above and also listed below:
Service Name: The default is AlienDVR. This name is displayed as a reference name
on the TV and may require changing. For instance if the service is not
for connecting an Alien DVR HDMI input but for a Sky box. This is
for display information only.
Provider Name: The default is AlienDVR. This could be the company installing or
supplying the equipment or contact telephone number and is only for
information purposes.
LCN: Logical Channel Number. The default setting is 800. If you are using
more than one MOD200 e.g cascading two or more MOD200s, then
each additional unit will need a different LCN. Example call them 801,
802 etc.
Frequency: The default setting is CH60 786.00 MHz. This setting may clash with
the channels used locally in the area. Also when cascading two or
more MOD200s, then each additional unit will need a different channel
number e.g CH61, CH62 dependent on channels not used in the area
installed.
RF Level Adj: The RF Level adjustment is set by default to -30dB. This normally
works okay when you are inputting a strong HDMI signal. However if
longer runs are involved you may need to reduce this setting.
Change Password: The unit is set by default to 0000 and therefore does not need a
password to enter the menu. Just press OK. Use the menu option to set
if required.
The above parameters will need changing when you are cascading multiple MOD200 units
and or the default channel 60 clashes with an identical channel used locally in your area.

10. Using the Menu
As the MOD200 is built for UK use and default menus use UK settings, in many instances
there will be no requirement to change menu parameters. As explained previously there are a
few settings that will need changing if you are utilising multiple MOD200 units i.e cascading
units or when the default channel 60 is already being used.
The following takes you through the menu structure for making these specific changes only.
Advanced menu options can be found later in the menu 11.2 Advanced Settings.
10.1 Changing Basic Menu Parameters
When the modulator is first connected to power it will display
Initial ….
Please Wait …..
If you have no input signal connected it will display Keyboard Locked
NO SIGNAL IN
else it will display Enter Password
0000
If no password has been set, click on OK button else enter the correct password
The MOD200 will then display Network Setting the first menu section. Click on the right
arrow button to move to the next menu heading called CH&Enc Settings then click OK to
update this section parameters. The first parameter in this section is Service Name.
CH&Enc
Service Name:
Press the OK button if you are changing the Service Name and the default name first letter,
will start flashing. Pressing the UP or DOWN arrow key will change the character to alpha
upper case format, followed by numbers, followed by alpha lower case.
This may be necessary if you are cascading MOD200s so you can identify the HDMI input
connected. The UP arrow goes forward through this character selection and the DOWN
arrow goes backwards. Use the RIGHT arrow button to move to the next character. Then
press the OK button to select the full name. This name will be displayed on the TV screen.
Now click the RIGHT arrow again to move to the Provider Name.
Provider Name:
Press the OK button if you are changing the Provider Name and the default name first letter,
will start flashing. Pressing the UP or DOWN arrow key will change the character to alpha
upper case format, followed by numbers, followed by alpha lower case.
This may be necessary if you are cascading MOD200s so you can identify the installer or
contact telephone number. The UP arrow goes forward through this character selection and
the DOWN arrow goes backwards. Use the RIGHT arrow button to move to the next
character. Then press the OK button to select the full name. This name is for information
only. Now click the RIGHT arrow again twice move to the LCN (Logical Channel Number).
Page 11
MOD200 HD Modulator XMOD200
Email: support @ kovert.com 11
LCN (Logical Channel Number):
Press the OK button if you are changing the LCN.
The LCN must be unique if you are cascading MOD200s. Use the RIGHT arrow key to
select the digit to be changed. Then use the UP or DOWN arrow buttons to select the
required digit. Use the RIGHT arrow key to select the next digit to be changed. Then use the
UP or DOWN arrow buttons to select the required digit. Then press the OK button to select
the required number string. Then click on the MENU button and using the RIGHT arrow
button select RF Setting then click OK to update this section parameters. The first
parameter in this section is Frequency.
RF Setting
Frequency:
Set the channel and frequency band required for the output signal. Check that the selected
channel is not already being used by a current television distribution channel in either your
area, or if your TV is already using this channel. This will need changing if you are using
cascaded MOB200s as each MOB200 must be on a different channel and frequency. Note
that the frequency is automatically configured using the Bandwidth setting which by default
is set to 8MHz. So when the default is set on the first MOB200 to CH60 @ 786.00MHz when
you change the channel to CH61 the device will automatically add 8MHz to the CH60 setting
giving a frequency of 794.00MHz. To change the channel and frequency click on the OK
button to edit the setting and use the UP or DOWN button to increase or decrease the channel
number. You will see that the frequency setting will increase or decrease by 8MHz as the
channel number changes. Then click on the OK button to set the new values. To move down
the menu press the RIGHT arrow button.
RF Level Adj:
The MOD200 RF Level Adjustment is set by default to -30dB. The range for adjustment is
0dB ~ -30dB. This sets the level of RF amplification output but it is best to start at a very low
level so that amplification is balanced across the devices connected and signals do not swamp
the resultant receiving device/s. To change the RF Level Adj setting move down to the
setting using the RIGHT arrow button and then click on OK to edit the setting. If you click
the DOWN arrow button the -30dB will reduce to -29dB, then -28dB and so on, but if you
press the UP arrow key it will increase the setting to 00dB, then -01dB, then -02dB and so
on. To accept the new setting click OK to stop the value flashing.
Load Default?
If you wish to return to manufacturer’s settings select Load Default? with RIGHT arrow
button and then click on OK. You will now see Yes or No flashing. Ensure the correct one is
highlighted and click on OK. The MOD200 will now be defaulted following save.
New Password
Although there is no need to set a password the default is 0000. If you select New Password
with RIGHT arrow button and then click OK the first 0 will be flashing. Use the UP arrow
button to advance numbers from 0~9 and after setting the first number use the RIGHT arrow
button to move to the next number. Complete the number which can be 0000 ~ 9999 and
select OK button.

Save Settings
Once a parameter has been successfully changed the menu category will have an asterisk *
attached. If you return to the menu by clicking MENU button and then click MENU again to
close the menu, you will see the following message displayed: Apply Setting?
Yes No
With the YES flashing click on OK and you see the message
Processing Wait a moment …. And return to Network Setting menu for a few seconds
and then when unit times out, returns to Keyboard Locked display.
10.2 Changing Advanced Menu Parameters
If you need to change other menu settings, which should not be necessary in the UK, these
are described in the menu structure in section 8. Navigating the Menu System.

11. Troubleshooting Options and HDMI Pass-Thru
11.1 Compatibility
The MOD200 converts an HDMI signal into a digital RF signal for distribution to TVs
containing HD digital tuners. Note that the MOD200 outputs MPEG-4 and not all TV's
support this as some are MPEG-2.
11.2 HDMI Resolution
As HDMI TVs can be either 720P HD Ready or 1080P Full HD, the first step is to check that
the DVR resolution input matches that of the TV. So if the TV is 720P HD Ready then the
DVR resolution must also be set to 720P. The MOD200 will output the same resolution as
input. Resolve this first before continuing.
11.3 Installation method
In order to undertake the installation of the MOD200 it is recommended to start by just
connecting the DVR direct to the MOD200 and the MOD200 via the RF out to one TV.
Then re-tune the TV. This will prove that the MOD200 is working correctly and one TV
proves that the setup used is correct.
Now connect the main TV aerial feed from the roof, to the MOD200 RF IN feed. When this
stage works okay, take the RF OUT feed into the RF distribution amplifier and from that into
the single TV. If that works okay add extra TVs.
Note that if the aerial has a Masthead amplifier please refer to “Section 7. Installation when
using a Masthead Amplifier.”
11.4 HDMI Pass-Thru
The MOD200 incorporates an HDMI Pass-Thru option so that when using the Alien DVR
HDMI output into the MOD200, you still have the option for an HDMI feed for other
functionality.
