NOTE: BEFORE INSTALLATION
Please test each unit UNMOUNTED ON A TEST BENCH with your Test TV before installing your units to
ensure you are receiving the Test Pattern signal. Then Program your unit. If installing Multiple units,
make sure each unit has its own frequency it's broadcasting on as well as its own Major/Minor.
This makes troubleshooting easier.
To test your unit, simply connect your TV with a short piece of Coax cable to the RF out of the Unit. No
HDMI needs to be connected for this test.
Scan for channels on the connected TV. Depending on your supported TV standards, scan for digital
channels.
After the scan is complete, you can tune to channel 1.1, and the test pattern will be visible.
By default, our unit is set to QAM (J.83B Cable) mode. This can be changed by referring to our WEB
INTERFACE CONFIGURATION GUIDE on Page 6.

•RF ATTENUATION: Built-in digital Attenuator to lower the RF output level. The default setting
is 0 dB, which is full strength. The higher the number, the lower the signal strength.
•MIXER MODE: Used for combability in QAM for older TV’s that still use ATSC 1.0 format. By
default, we are in the max combability mode for all TVs. if you have issues finding the TV or
the channel is found but the screen is black and only audio plays switch to Alternate mode.
•FIXED EDID: Auto is the default mode which allows any HDMI source to feed into the unit to
pass its set resolution. If you have issues where your HDMI source is not being detected by the
unit then set this option to the desired resolution supported by your HDMI source, e.g. 1080,
1080i, 720p. This sends a command to the HDMI source that the only support resolution is the
valve set in this option. This forces the resolution to be stuck in the set value and may not
change.

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 unit 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 unit’s 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
Frequencies that are available such as ATSC (Over the Air Antenna) signal. Check the operating
frequencies of the other signals (i.e. other modulators, OTA channels, etc.), and be sure to set these
units to other valid frequencies.
Depending on your setup we recommend for you to use an active splitter or combiner with more than
6 units, 40+ TVs or using multiple splitters (each splitter will lower the DB level 5-10dbs depending on

Pro Video Instruments
VeCOAX Network Compact HDMI RF Modulator Manual
10
the quality) to ensure you get a clear signal to all your TVs no matter the distance. If your system
works without one then it is not necessary.
COMBINING SERVICE PROVIDERS SIGNALS OR ATSC WITH YOUR
DEVICE
For Combining ATSC (Over the Air channels) you must find the frequencies that are used by your local
stations. This information can usually be found online by searching for, “(insert your local area) ATSC
frequency chart.” This typically shows all the Frequencies used in your area. Find the ones that are not
used and write those down. Set your device(s) to those unused frequencies. Test using your Test TV.
For combining with Cable Service provider, the same rules apply. You can contact the local service
provider of your basic cable to find the frequencies that they use and find the ones that are available
for you to use. If you wish to inject into a Digital Cable Converter box or STB(set-top box) most of the
time the service provider will include a channel you may broadcast onto or some providers require a
specific PID’s to be set which can be set in the ADVANCED OPTIONS MENU in order for the Set Top
box to be able to read the channel.
AUDIO ENCODING SETTINGS
The unit has three standards of Audio Encoding. Depending on your local and supported format per
TV you can set the following:
•AC3 –2.1 Dolby Digital Audio US/Canada Standard for Broadcasting
•MPEG –MPEG 2 Layer II used in DVB-T EU Standard.
•ACC - Advanced Audio Coding or MPEG-4. Used in some ATSC broadcasts and ISDBT format.
Supported by Most TVs worldwide.

TROUBLESHOOTING
NO VIDEO
Check for the TEST PATTERN using a test TV, using the unit’s basic setup with default settings.
1. Connect the unit to TV via coax cable. DO NOT connect the HDMI source.
2. Run channel scan on TV (Auto or Cable). After the channel scan, the TV will find the default
channel (1.1).
3. Tune the TV to default channel. TV will show a test pattern ("No Valid Video Input.")
Check for TEST PATTERN using intended channel settings.
1. On the unit’s web interface, set signal standard, Frequency (channel), Major & Minor Channel
numbers to what you wish to use.
2. Confirm that the Frequency is not being used by any other equipment and the Major/Minor
channel number being used is unique.
3. Run channel scan on TV. TV will find the programmed channel.
4. Tune to the programmed channel. TV will show a test pattern ("No Valid Video Input.")
If no TEST PATTERN...
-Check coax cable connection between TV and unit. Test with a different cable if possible.
-Check the TV scan method. Make sure TV is set to scan for the signal type (STANDARD) set on
the unit’s menu. (ATSC corresponds to Over the Air, J83B is QAM Digital cable, etc.) FOR
DEFAULT SETTINGS: set TV to scan for Auto or Cable.
-In rare cases, some TVs may not be able to display the test pattern. Rule this out by connecting
a "dumb" HDMI signal source (e.g. DVD player), then scan for channels on the TV.
-Test with another TV to rule out TV issue if possible.
If TEST PATTERN works but there is NO VIDEO from intended source…
-Check HDMI cable connection between source and unit. Disconnect HDMI source and
reconnect it to establish a new HDMI handshake. Test with a different cable if possible.
-Check resolution settings on the source. Recommended setting is 1080p FIXED or 720p FIXED. If
the source is a computer, set Display to “Extended mode” or “Extend these displays” and set to
1920x1080 or 1280x720.
-In the web interface, go to Advanced Options > Fixed EDID setting, and change from Auto to
match the fixed resolution setting on the source. For instance, if the source is set to 1080p
Fixed, change Fixed EDID to 1080p.
-Test with a different source (e.g. DVD player) if possible
-If possible, test with a different TV with a different make/model.
-Use default settings on the unit. (To reset to default settings, press and hold the “RST” button
for 15 seconds while the unit is powered on.)

AUDIO IS NOT IN SYNC WITH VIDEO
-This may occur if the audio output goes separately to a sound system before the video goes
through the unit. You can purchase an audio delayer to sync the audio before it goes into your
sound system or take the audio feed directly from the output of a TV tuned to the channel.
-To fix, adjust the Audio Delay settings on the affected TV. (This varies from TV to TV, see your
TV documentation for more info.)
UNIT WON’T POWER ON
-Check the connection between the power supply and the unit. The cable screws securely into
the DC jack on the side of the unit.
-Check the connector, cable, and power supply to make sure there is no damage.
-Check that you are using the original power supply for your model.
-Test using a different power supply for this model, if one is available.
-Test with a different known working outlet.
-Ensure that all the nuts on the connector are secure and not loose.
LOSING OTHER CHANNELS WHEN CONNECTING UNIT TO EXISTING COAX NETWORK
-There may be a channel conflict. Check the unit’s Frequency and Major/Minor settings and
make sure they do not match any other equipment in the network.
-The unit’s signal output may oversaturate other signals on the network. To attenuate the signal
from the unit, in the menu go to Advanced Options > RF Attenuator, then change from 0db, in
5db to 10db increments, and retest. Also, consider amplifying the other signals in the network
to achieve ideal balance.
NOT ALL OF MY TVS PICK UP THE CHANNEL(S) IN A NETWORK WITH MULTIPLE TVS
-There may be a channel conflict. Check the unit’s Frequency and Major/Minor settings and
make sure they do not match any other equipment in the network.
-There may be signal loss on the coax network between the unit and the affected TVs. To check
for this, remove the unit from the network and connect it directly to the affected TV. Then,
rescan for channels.
-If the above test works, add an amplifier to your network before the affected TVs.
MY TV DOESN’T ACCEPT DIGITAL SIGNAL (ANALOG ONLY)
-Many older TVs (sold before 2009) only accept analog cable or over-the-air signals. These TVs
will require a digital converter box. Typically, these are sold as Digital to Analog converter boxes
or set-top boxes.
-If using a converter box, set the STANDARD on the unit’s menu to match the type of converter
box. (For Over-the-Air, set the unit to ATSC. For Cable, set the unit to J83B.)

ON AIR LED LIGHT IS BLINKING OR OFF (POWER LIGHT IS ON)
-Check resolution settings on the source. Recommended setting is 1080p FIXED or 720p FIXED. If
the source is a computer, set the display to “Extended mode” or “Extend these displays” and set
to 1920x1080 or 1280x720.
-On the unit, go to Advanced Options> Fixed EDID setting, and change from Auto to match the
fixed resolution setting on the source. For instance, if the source is set to 1080p Fixed, change
Fixed EDID to 1080p.
F.A.Q –FREQUENTLY ASKED QUESTIONS
INSTALLING MULTIPLE UNITS? –
Please see page 9 “Installing Multiple Units” Each unit MUST have its own frequency and major channel
number.
QUESTIONS ABOUT THE DIFFERENT STANDARDS? -
This refers to the broadcast standard of the RF output. North American standards are J.83B (digital
QAM Cable) and ATSC (digital over-the-air antenna). International broadcast standards supported
include DVB-T, DVB-C, ISDBT, and DTMB. Be sure to use a standard that is compatible with your TV and
region.
WHAT IS THE ADVANCED OPTIONS MENU? –
The Advanced Options Menu allows adjustments of PSIP and other tweaks such as the Units RF strength.
See page 7.
TRYING TO MIX SIGNAL WITH OTHER MODULATORS? –
Please ensure you don’t set our unit on the same frequency as your other modulators as well as
balancing the RF level. If you broadcast our unit on the same frequency as your other modulators it will
cancel each other out or cause unwanted results on your TV image such as two channels split on one
screen. Please see Page 10 for more information.
MIXING OVER THE AIR ATSC SIGNALS WITH OUR UNIT?
Please see page 10 for more information.
MORE THAN TWO UNITS ONLY PICKING UP A FEW CHANNELS AND NOT ALL?
Ensure that each unit has its own Frequency, Major, Minor, and Channel Name.

Pro Video Instruments
VeCOAX Network Compact HDMI RF Modulator Manual

If you have multiple units connected with a splitter or coax combiner, please check the signal coming
from the combiner directly plugged into a TV and scan for channels. You should be able to pick up all the
channels. If not, we might need to amplify the signal. Coax has a lot of variables to account for, so we
always need to start from the source and work our way up. Sometimes cheap splitters or combiners can
introduce harmonics that create noise causing the TV to skip a channel because it’s too dirty of a signal
to pick up. It is rare but happens from time to time with cheaper coax combining equipment.
BALANCING SIGNAL - SIGNAL NOT REACHING ALL THE TVS
This could be that the signal strength isn’t enough to reach all your TV sets. For example, if you have 12
TVs in a chain and the last 3 won’t pick up your channel, then you can buy an inexpensive coax amplifier
from online and add it to the coax line on the unit to boost the signal to reach the last 3 TV sets.
Please note in some cases after amplification of the signal the first few TVs might start to see digital
artifacts or signal issues. This is due to the Signal becoming stronger for the first few TVs and as the
signal travels down the coax cable it slowly becomes attenuated which results in the other TVs not
having this issue. To combat this, please add an inline digital attenuator, or use the Advanced Options >
RF Attenuator option.
WHAT IS EDID?
Extended Display Identification Data (EDID) is a metadata format for display devices to describe their
capabilities to a video source (e.g. graphics card or set-top box). It is the Basic HDMI language used for
device to communicate their supported resolution as well as audio formats. When you plug let’s say a 4k
Blu-ray player into your TV and your TV only supports 1080P. The TV will communicate this with the Blu-
ray and the Blu-ray responds by setting its resolution automatically to 1080P and not 4k.
CHANGING THE CHANNEL ON MY SET TOP BOX RECEIVER CAUSES ME TO LOSE THE
CHANNEL FOR 15-45 SECONDS BEFORE DISPLAYING AGAIN.
Please ensure that your HDMI source is set to a Fixed 1080i/p or 720P and only one resolution is
selected. If you are still having issues, please try using our advance menu > Fixed EDID > 1080 or 720,
depending on the supported resolution from your HDMI source.
WHAT DOES MAJOR AND MINOR DO?
Major and Minor are used as a reference number for your TV to understand. When you tune to channel
10.1 the tuner goes to the frequency you have set on the unit. When a TV scans it looks for the
Frequency first and then sees the attached VCT (virtual channel table) data attached to that channel.
This then overwrites the Physical channel number as shown in the frequency chart (783.00mhz is
physical channel 122) and stores the channel with the assigned Major/Minor you have set on the unit.
WHAT IS THE DIFFERENCE BETWEEN FREQUENCY CHANNEL LISTED ON THE CHARTS VERSUS
THE MAJOR MINOR CHANNEL NUMBER?

Pro Video Instruments
VeCOAX Network Compact HDMI RF Modulator Manual
17
The frequency listed on the charts is what is called the Physical channel number. When no VCT (virtual
channel table) is assigned, the Tuner defaults to the Physical channel number. (For example,
783.000mhz QAM is channel 122.) When VCT is enabled and a Major/minor is set on the unit, the TV will
overwrite its normal programming and use the Assigned number such as 10.1 or 1.1 which is the default
on the unit. Most modern TVs won’t accept or save a channel without VCT so by default we can not
disable VCT to ensure the max combability with all TVs. If you wish to use the same Channel number as
the Physical channel number, then set the Major/Minor to match. For example, 195.000Mhz QAM is
physical channel 10. So, we set the Major/Minor to 10.1. Each digital cable channel must have a Major
and Minor. So, all Channels will display its Major and Minor number 10.1, 11.1, 12.1, 13.1 etc.
