Pro Video InstrumentsINSTALLING MULTIPLE UNITSTo 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 unitdirectly connected to a Test TV first with a short piece of coax before making it a permanentinstallation such as a rack mount to make troubleshooting easier. Once you have all your unit’s setuptest 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 andFrequency’s that are available such as ATSC (Over the Air Antenna) signal. Please refer to your othermodulators settings to find the frequencies the populated and set your unit to a different set. Pleasesee combining ATSC/QAM signals in our manual below for more information about combining withother Digital Signals from ProvidersTo change the Frequencies of each module, press enter button the unit to enter the menu. Navigateusing the keys to FREQ. Press enter and use the navigation keys to change the numbers. Thefrequency is in Kilohertz. So 783Mhzs would be 783000 kHz on the unit. Once you have set theFrequency, press Enter, then move on to changing the Major/Minor channel as well as the short nameif you wish. Once you have set all your settings press ESCAPE. This will prompt you to save yourchanges. Use the navigation keys to Highlight Yes and press Enter. The unit will now go back to themain screen and restart the encoder. Once the unit saves the settings you will see “transmitting,” anda Solid Blue LED on the “ON-AIR.”Write down these values or channel numbers, or put a sticker on each unit with the newly assignedfrequency and channel Number so it will be easy to troubleshoot the unit in future without the needto reset it or dismantle everything. Depending on your setup it’s suggested to use an active splitter orcombiner with more than 6 units, 40 TVs or using multiple splitters (each splitter will lower the DBlevel 5-10dbs depending on the quality) to ensure you get a clear signal to all your TVs no matter thedistance. If your system works without one then it is not necessary. Again, this is a suggestion and notrequired for the operation of your devices.VeCOAX Compact RF Series Modulator Manual13
Pro Video InstrumentsCOMBINING SERVICE PROVIDERS SIGNALS OR ATSC WITH YOURDEVICEFor Combining ATSC (Over the Air channels) you must find the frequencies that are used by your localstations. This information can usually be found online by searching for, “(insert your local area) ATSCfrequency chart.” This will give you a nice table that shows all the Frequencies used in your area. Findthe ones that are not used and write those down. Set your device(s) to those unused frequencies. Testusing your Test TV.For combining with Cable Service provider, the same rules apply. You can contact the local serviceprovider of your basic cable to find the frequencies that they use and find the ones that are availablefor you to use. If you wish to inject into a Digital Cable Converter box or STB(set-top box) most of thetime the service provider will include a channel you may broadcast onto or some providers require aspecific PID’s to be set which can be set in the ADVANCED MENU in order for the Set Top box to beable to read the channel.AUDIO ENCODING SETTINGSThe unit has three standards of Audio Encoding. Depending on your local and supported format perTV you can set the following: AC3 – 2.1 Dolby Digital Audio US/Canada Standard forBroadcasting MPEG – MPEG 2 Layer II used in DVB-T EU Standard. ACC - Advanced Audio Coding or MPEG-4. Used in some ATSCbroadcasts and ISDBT format. Supported by Most TVsworldwide.VeCOAX Compact RF Series Modulator Manual14
