INSTALLING MULTIPLE UNITS
To install multiple units on the same coax network, make sure to
CHANGE
the
Frequencies, Major/Minor, and Short Name of each Module
BEFORE
you connect
them to the same coax network, so there will be no Channel Conflicts. By default, each
unit will be set the same.
Please Test each unit directly connected to a Test TV first
with a short piece of coax
BEFORE
making it a permanent installation such as a Rack mount to make
troubleshooting easier. Once you have all your
units’
setup test again with a test TV
first before combining the units with your coax network.
If you have other modulators or Digital signals you must find a harmony between the
RF levels and Frequency’s that are available such
as ATSC (Over the Air Antenna)
signal. Please refer to your other modulators settings to find the frequencies the
populated and set your unit to a different set. Please see combining ATSC/QAM
signals in our manual below for more information about combining with other Digital
Signals from Providers
To change the Frequencies of each module, press enter button the unit to enter the
menu. Navigate using the keys to FREQ. Press enter and use the navigation keys to
change the numbers. The frequency is in Kilohertz. So 783Mhzs would be 783000 kHz
on the unit. Once you have set the Frequency press enter and then move on to
changing the Major/Minor channel as well as the short name if you wish. Once you
have set all your settings press ESCAPE. This will prompt you to save your changes.
Use the navigation keys to Highlight Yes and press Enter. The unit will now go back to
the main screen and restart the encoder. Once the unit saves the settings you will see
“transmitting,” and a Solid Blue LED on the “ON
-
AIR.”
Write down these values or channel numbers, or put a sticker on each unit with the
newly assigned frequency and channel Number so it will be easy to troubleshoot the
unit in future without the need to reset it or dismantle everything. Depending on your
setup it’s
suggested
to use an active splitter or combiner with more than 6 units, 40+
TV’s or using multiple splitters(each splitter will lower the DB level 5
-10dbs depending
on the quality) to ensure you get a clear signal to all your TV’s no matter the distance.
If your system works without one then it is not necessary. Again this is a Suggestion
and not required for operation of your devices.
