You can reset the device from the front LCD panel. Press the middle button on the Petit that looks like a box with 3 lines in it. The first time you press it, it will show ATSC or J83b. Press it again and it will show DHON or DHOFF. On the third time, you press the button it will say ASR. When you get to the ASR button press the down arrow to execute the factory reset. The process should only take 30-60 seconds and you'll be back up and running. If you have any further questions please don't hesitate to contact me.
Do you have any more information of what the application necessitates besides HDMI? Do you they require certain resolution or audio capability? Is the latency or size of a unit an issue? We have a plethora of units that can fit the information you provided. The Petit would seem fine, or the AC3-CMOD, we also have multi-channel units like the Thunder-4... All can take HDMI and output to RF

2) The modulator should be able to feed all of the TV's. I would think you'd want to put it near the other Comcast gear. But it does it's 2 blocks away? Is there another headend room or electronics closet closer to the facility you can put the equipment in? In either case you can use the RF Petit, or you can use something like the Thunder-4 for multiple HDMI inputs. All you need is a coax combiner, to get the feed from Comcast and our units together. You also should find out which channels are being unused by Comcast so you can put the QAM channels on open frequencies.
3) Yes you can put it on channel 2; any RF combiner from 5-970mhz will work. I assume you will need QAM 256
Hello, that's great news. Happy to hear the install went well.
2) Yes, we totally get that. They just so happen to be countless helpful documents on the product page, which can be downloaded, and also a bunch of instructional videos on how to do that. The box is pretty small and we just put in the install manual; all other docs and helpful tips tricks and extended installation docs we leave up on the website. Perhaps we should add a note in the units box that those are available via the web

I would like to find a device that: |
- connects to the cable system at a 50 bed assisted living facility to show content on a certain tv channel |
- would like to connect a laptop to the 'device' and broadcast whatever is showing on the laptop to a tv channel on all tvs |
- would like to have a dvd/vhs player connect to the 'device' and broadcast to all tvs |
broadcast video and sound to all tvs |
How many HDMI sources do you have total?
|
i figured i could buy a splitter if needed. Also a computer with dvd player and cut out the vhs
|
So just one HDMI source?
|
yes
|
this is what currently use = DVISn Nano Encoder – RF Out
|
The DVISn (Nano) encoder/multiplexer with RF output is the most cost-effective and smallest form factor solution within the DVIS line of products for inserting locally generated content into an MDU, hotel or commercial property in digital format. It is ideal for applications requiring a low-cost, basic solution for SD MPEG-2 encoding and QAM-based distribution or insertion of locally generated content into a coax network. Extremely compact and wall mountable, the DVISn device fits into virtually any space and includes fully integrated audio/video encoding, multiplexing and QAM modulation. |
We can add this HDMI "Channel" to an assigned number not being used by your current CATV system, and any TV set to that channel wil be able to get the TV
|
so it should be easy to swap devices ?
|
Yes very much so
|
we can even preconfigure the device to your current settings so when you get it, you just have to plug it in
|
do use third party to come on site ?
|
or I should be able to handle ?
|
You should be able to hook up a few cables
|
we will set it up like your current unit, all we need to know is which channel you're currently sending video on
|
dont recall - but i find out when time comes
|
so its matter of ordering via thor website and you config and ship and i plug in - done?
|
correct
|
just send us an email after you order with the information we need, and we'll do the rest
|
this is the least expensive transmitter we offer
|
We have two compact optical RX options
|
RF over Fiber equipment only works on singlemode fiber. hopefully thats what you have installed. If you have multimode, nothing in the world will work.
|
That's bad news, because I'm afraid the cable is multi-mode.
|
You can not put RF on multimode fiber. flat out doesn't work.
|
How can I tell what type of cable has been installed?
|
single mode cable is usually yellow
|
MM is usually orange
|
Ours is orange. OK, and thanks for the input. Time to think about a Plan B, which would involve replacing the RG-6 with a better grade coaxial cable. What would you recommend?
|
RG 6 is the standard most people go with.
|
You can go up to RG11
|
but realistically at 700ft you'll need Amps regardless
|
We're getting way too much signal attenuation over a run of that length.
|
Might be an easy solution if you just have the one run giving you issues. Then again if you think your cable is damaged, installed poorly, thus giving you too much attenuation then replace it with RG 11 and throw on a DA
|
technically speaking you shouldn't even be able to get a signal on the other side
|
900MHz
|
20.1dB |
6.0dB |
5.4dB |
So in this table RG 6 versus RG 11 is only .6db of loss difference per 100ft
|
I would get an amp, don't worry about the cable
|
It's just that single long run. The rest of the CATV distribution system uses amps.
|
if its RG59 then replace the coax, if its RG6 then leave it
|
our amp is +30 db so you'll replace about 500ft of cable with one unit
|
Tx
|
Does the amp go at the transmitting end or the receiving? Or in the middle?
|
depends on how much power you're reading at the transmission site, if its high, then go middle, if its low at the outset, then go transmission then middle
|
get an RF meter and check the power at multiple points and see where you are
|
you don't want to overdrive the signal to high and then go too low, you'll degrade the quality that way
|
Are you recommending a specific amplifier?
|
ours never have issues
|
The RG-6 is in the ceiling. To stall an amp at a half-way point would require an electrical outlet that's not there.
|

There are some other was to deal with the HDMI real-time distribution
1) HDMI over Ethernet, this is also a very convenient day and not
noticeable delay
https://thorbroadcast.com/product/4k-hdmi-over-ip-ethenet-cat6-rj45-extender-300feet-with-8230.html
2) HDMI over fiber
https://thorbroadcast.com/product/hdmi-fiber-extender-with-ir.html
3)SDI over fiber
https://thorbroadcast.com/product/1-sdi-hdsdi-over-fiber-mini-extender.html
We have a lot of options for Qam Modulators. We have 8 Channel HDMI input modulators https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/239 They are a great value for price per channel. Terrific HD picture. We also have individual units like the RF PETIT that can be mounted in Chassis as well https://thorbroadcast.com/product/petit-hdmi-rf-modulator-chassis-system-for-1-12-units.html/254 How many channels are you looking to do out of the 60? Or do you need all 60 replaced?
I have a couple questions about your RF modulator
|
I am looking to use an RF modulator to distribute video to 5 TV's we have outside in our service drive at our car dealership. I will need to split 1 to 5 and those 5 displays are about 150 feet away from the source. What splitter should I use?
|
Also, do y'all have dealers around Dallas, TX where I could go purchase your products?
|
Any splitter should work fine
|
We do have integrators in Texas, but resellers are online mostly
|
Ok, thank you. Thats what I needed!
|
No probelm
|
problem
|
Do you think just a regular splitter or an amplified splitter?
|
depends on the coax run
|
and the particular modulator you're looking at
|
Petit HDMI RF Modulator. Then about 150 ft run to the splitter and then short runs to the display. At most 30 ft.
|
I think you should be fine
|
Ok cool. Thank you.
|
standard splitter for 45-900mhz will be okay
|
satelite dish splitters go 1ghz to 2.4ghz
|
a regular old splitter is very inexpensive
|
First, please forgive my lack of "tech" terminology regarding your manuals.
|
I have a Thor digital TV tuner (H-STB-QAM-ATSC) and a Thor Modulator (H-HDMI-RF-PETIT). How do I tell the modulator to switch from coax (antenna input) to HDMI (DVD player) input? |
Hello
|
The modulator outputs a signal via RF from the HDMI source
|
so it needs to be on a vacant channel, if your antenna feed has channels 2-40 then put our modulator on channel 41
|
I will give that a try. Any vacant channel? I believe my antenna receives channels up to 58. Also, what channel should the Tuner be on or doesn't it matter?
|
the tuner can be set to the channel you want to watch
|
okay then set the modulator to 60
|
after that you need to rescan the STB for AIR
|
so it picks up your antenna, and also make sure the modulator is set to ATSC, not qam
|
Thanks. I will try that. Hopefully all will work fine. If not, I'll beg for more help!
|
you can also call tech support if you get stuck again, 1800-521-8467 ext 2 and they will help you resolve the issue
|
I can't call, because our cell phone doesn't get a signal at this location. I set the modulator to channel 65 and did a tuner rescan, with no results. Channel 65 does not show up on the tuner.
|
is the modulator set for ATSC?
|
and you're doing a scan for AIR on the STB
|
I need help with the terminology, please. How do I determine these 2 settings?
|
Using those 3 buttons you can setup the following:
|
1) Change the channel number |
2) Press HOME 1 time: changes the CABLE QAM (J83b) to AIR ATSC modulation (vice versa) |
3) Press HOME 2 times: changes DHCP ON or OFF |
4) Press HOME 3 times: Reset to default configuration (factory reset) |
https://thorbroadcast.com/ is sharing a file with you. h-hdmi-rf-petit-quick-connection-instructions1.pdf - (Size:2.82 MB) |
This is the manual for the modulator
|
so if you click the menu button on the front of the unit and it reads J83B then that is QAM, you need to change that to ATSC which is terrestrial antenna signal
|
QAM is Cable and ATSC is Antenna essentially, those are the two standards we use in North America
|
So we just need to get everything on the same standard, if you have an antenna on your house, then we need the modulator and STB decoder box to also be setup for Antenna, which is ATSC
|
The modulator offers 3 digital readout: J836, dHOF and ASr. Am I to use the ASr setting when scanning?
|
no stick on J83B which is north american QAM, press the down when its highlighted and it should switch to ATSC
|
press up on J83B to switch, then DOWN to SAVE
|
ASR will reset the unit back to factory settings, so don't play with that
|
Got it!! Thanks so much. So now if I replace the DVD player HDMI with a ROKU HDMI all should work well, yes? Again, thanks.
|
Yes that HDCP will work, you can find more specs on the product here
However this is not a 4k resolution product, so your dish hopper would
be better suited if you set it up for 1080i or 1080p/60
We do have 4k Resolution HDMI modulator, H-4K-UHD-QAM-IP
The encoders in an MPEG-2 system have a delay by nature. The encoder
takes in an uncompressed video or audio signal and applies various
techniques to reduce the data rate, so it can be sent as a modulated
TV channel.
The decoder, or TV tuner, also has some delay as it processes the
encoded data and reconstructs the original signal.
This process takes time and there is nothing that can be done to
eliminate the delay completely.
However, the delay should not be greater than 0.8-1s.
If there is a delay greater than 1s, it is likely that the delay is
coming from something other than the encoding and modulation process.
To test the delay caused by the modulator alone, you can send a clock
signal from a PC to the modulator and to a TV.
Take a picture of the PC screen and the TV next to it, and you will
see that the modulator delay should not be more than 1s.
It's possible that the delay is coming from the ATEM Mini Pro Extreme
or a combination of the ATEM Mini Pro Extreme and the modulator.
this is link to the Timer video you cosul use for testing:
https://www.youtube.com/watch?v=9cQT4urTlXM
There are different professional and commercial modulators available
that have different chipsets. They can encode and modulate at about
0.3-0.5s, for example,
the H-2ADHD-QAM-IPLL
(https://thorbroadcast.com/product/2-hdmi-ypbpr-hd-digital-tv-modulator-qam-atsc-dvb-t-8230.html).
The Petit modulator is capable of generating a single physical cable channel based on the frequency chart/channel table.
https://thorbroadcast.com/upload/files/220/catv-qam-channel-center-frequency.pdf
It doesn't have a transport stream multiplexer built into it, it cannot multiplex two programs on a single channel.
You can, however, place these programs on two separate physical channels. For example:
CH4 - 69MHz
CH5 - 79MHz
You can then assign VCT virtual channel numbers, such as 4.1 for the first program and 4.2 for the second program.
This way, the TV will scan and display visual channels, regardless of the fact that they are being transmitted on physical channels 4 and 5.
Please let me know if this explanation is clear.
If you require the ability to multiplex two or more programs on a single frequency, we do have other multi-channel modulators available.:
