Hi All.

I am new in the forum.

I want do build an USB tuner using Minitioune and FT2232H minimodule.

Question:

Is is possible to use the DNBU24513IST Tuner? (STV6110A and STV0903B )

If yes , do you have the pinout information? Is it the same as DNBU10711IST NIMtuner?

In this old post, the DNBU24513IST was metioned as a possible solution to work with Minitioune:

https://forum.batc.org.uk/viewtopic.php ... t=20#p9015

List of NIM that would be good:
Samsung
- DNBU10512IST ( utilisé aussi par ModuleNIM de l'AP-IPbox 9000HD) 3 unités en test à la maison
- DNBU10711IST ( 1 acheté sur Ebay utilisé sur proto MiniTioune, 10 autres arrivent dans 1 ou 2 jours)
- DNBU24513IST ( utilisé aussi par ModuleNIM de l'AZbox Premium HD+)
- DNBU10512ISA (?)

Thank you very much!!

Regards

Joe

Yes it will work with Minitioune.
It seems similar to the Samsung NIM I have used for my first MiniTiouner prototype
I have already used
- DNBU10512IST (2x "F connectors")
- DNBU10711IST (1x "F connector")

The connector must be the same but take care, between Horizontal and vertical model, the 2 lines of pins are inverted.

Hi Jean Pierre!

I am sending attached the tunner model that i want to use.

Do you have the pinout information for this tuner?

Thank you again

Hi

I will try this configuration pinout for DNBU24513IST using the TMBU24112lMB1 pinout as a reference but changing the voltages from pins 3,5,10 and 11

I am not sure about the voltages..

The FTDI2232 and minitioune test is ok.. now i only need the tuner working...

some ideias or suggestions?

Thank you!!

Joe

Hello,

Finally I have found one of this NIM in my stock:


I have found all pins, but not number 9

pin 1 LNB A ( tested 0 ohm between the pin and the upper Fplug)
Pin 2 LNB B ( test 0 ohm between the pin and the lower Fplug)
pin 3 5v voltage for the preamp transistor ( 5v )
pin 4 GND ( tested)
pin 5 3.3v voltage for the ZIF tuner STV6110
pin 6 GND ( tested)
pin 7 GND ( tested)
pin 8 GND ( tested)
pin 9 ? chip select ?

pin 10 3.3v for demod STV0903
pin 11 1v for demod STV0903 NOT 1.1V !!!
pin 12 Diseqc1 (22 KHz in?)
pin 13 Diseqc2 (22 KHz out?)
pin 14 Reset
pin 15 D0
pin 16 D1
pin 17 D2
pin 18 D3
pin 19 D4
pin 20 D5
pin 21 D6
pin 22 D7
pin 23 BCLK (clock)
pin 24 SYNC
pin 25 VALID
pin 26 ERROR
pin 27 SDA

Hi Jean Pierre!

Very good news

THANK YOU !!

Hello all

I did my first test using the DNBU24513IST with Minitioune.. it works !! (Tested with V0.8 version)

And the results are very good.. good image, fast lock.. even using Low SR.
I tested using 77ks , 444ks , and FTA channel from satellite with 28888ks.. all worked fine.

For the transmitter i used the Raspberry pi 3 with RPIDATV and Ugly mode output.

Jean, your Minitioune software is very good.. Congratulations!!

Attached some pictures of my setup and results.

Thank you!

Regards

Joe
