BATC Forum

Hello,
I start with Portsdown 2019.
I also use a REF Union Minitiouner Pro but it does not work with my Portsdown 2019.
My question is: is the CRF Minitiouner Pro compatible or not with the latest version of Portsdown 2019?
Thank you. Merci

Hi

Are you trying to use the REF Union Minitiouner Pro with the Portsdown as a receiver? If so, I do not know why it does not work as I do not have one to test with. The receiver in the Portsdown is only tested with the BATC Version 2 MiniTiouner hardware. If someone could give me a REF Union Minitiouner Pro I would be able to test it with Portsdown (and possibly fix any problems).

Or are you saying that the REF Union Minitiouner Pro cannot receive transmissions from the Portsdown 2019?

I tried with a MiniTiouner Pro V2 and there's no voltage on the F socket by default - the RT5047A 13v/18v/22kHz chip needs to be turned on.

Looking at the schematic, the RT5047A is turned on with a high on AC4 from the FT2232H (EN_LNB). Low / high from SEL_LNB on AC7 controls 13v / 18v. The 22kHz waveform to the RT5047A comes from the NIM, so would have to be turned on there.

There seems to be only a single RT5047A on the Pro, whereas the Pro V2 has a second one to control the other F socket. For this one, EN_LNB is on AD5 and SEL_LNB is on AD4.

The F socket on the NIM that we normally use, the upper one furthest away from the pins, has its voltage feed on pin 2 on the NIM, marked LNB_A2 and is referred to as LNB2 on the Pro V2 schematic.

bonjour,

The different translations from French to English and from English to French (to read your answers) have modified my question a bit and make it difficult to understand your answers ....
I use Minitiouner Pro V2 from the REF Union (F6DZP) and I have no video reception via Porstdown 2019. I use the top F plug (A for Minitiouner).
no one else tested?

Salut

Utilisez-vous le satellite ou la réception terrestre? Le récepteur Portsdown ne contrôle pas la tension d’un LNB satellite. Ca peut être le problème.

bonjour,
it was for the qo-100 satellite.
I think I will continue to use my Minitiouner Pro V2 (R.E.F) as before, without using Portsdown...

Dear sir:
Is it true that the Porstdown does not handle the LNB voltage (18V) of the Minitouner pro 2? How do I connect the Minitouner to the Raspi? For any free USB of the raspi? Or do I connect it to the computer directly? Are there instructions on how to use the Minitouner with the Porstdown?

Hello
I use the pro 2 from REF wiith the Portsdown. It works very well
On menu 1 you will see RX select this.
Then you will see the config button the lnb volts can be selected from the displayed buttons.
There is also the option to select input a or input b.

Terry

Hi Jabi

Just connect the Tuner directly to the USB port on the Raspberry Pi. As Terry says, the latest Portsdown version (Buster 2020 version 202006070) supports the LNB voltage switching.

Select the RX Menu, set the frequency and SR, then select VLC.
