Working my satfinder link. I'am not have EPM7128 CPLD Thanks Lizar66,

Working my satfinder link.

Check how accurately the finder measures the voltage (Setting -> Profi -> uLNB). Compare this measurement with real value. If there are differences, check the voltage divider R30/R31. Check it out with and without LNB.

I'am not have EPM7128 CPLD

An average of $ 3. I could send and already programmed, but our prices are not interesting, plus shipment ... For understanding our changing currency $ 1 = 27uah

Hi Lizard66,

Thank you for help. How much EPM7128 CPLD+Shipping.???

[PROFESOR]

Hi Lizard66,

My sat finder without uLNB Voltage 3.17V, With uLNB Voltage 3.20V

My sat finder without uLNB Voltage 3.17V, With uLNB Voltage 3.20V

It is very close to the range boundary. Make sure that these measurements are the same as the measuring instrument readings. If the voltage is outside the range 3,15-3,6V controller deems it an emergency and off the tuner and LNB. It is necessary to make, a real voltage measurements with an accuracy of +/- 0.1V, using R30/R31. In your case, R31 (2k71) must be greater or R30 must be less.

Tomorrow I'll get a parcel from Moldova and know how much it will cost to Turkey

Thanks Lizard66,

I'am change R31 2k7 Resistor value. R31 New value 2K8, uLNB Voltage measured 3.3Vdc Vp 13.0V Vh 18.0 fine work.

Now OK!

Lizard66,

What is, I2C - SW and xPSK Function.??

Тоже из этой оперы, только у PROFESSOR вольтаж был меньше, а у меня больше. Заменил два резистора (как на фото выше). Был 2.702 (0.125в) поставил 2.697 (0.25в) и заменил 24.12ком на 24.26ком (0.125в). Теперь по 3.3 вроде нормально (сам цвиркун показывает 3.27-3.30).

Hi yankiuzb,

R30 and R31 Resistor between measured, potantiel divider voltage value 0.33Vdc * 10 =3.30 Vdc.

Применение прецизионных резисторов решает эту проблему автоматически, ну а за неимением таковых приходится покупать жменю обычных и подбирать подходящие по номиналу.

What is, I2C - SW

Then we say the controller which of the additional equipment connected.
"Mag" - magnetometr (compas) lsm303
"TSr" - TS-Reader epm7128

and xPSK Function.??

This menu is for debugging, you can see the contents of the registers of the demodulator. Over time, I will remove.
