motor problem

[Demby]

How do I test the voltage out of my Twinhan pci card? I bought a dish, motor and twinhan 102G card, and the motor won't work at all. No shorts or open circuits. I want to test voltage out of card, and also want to attach a separate supply to the motor to test it.

It's almost always a driver issue. If you want to test voltage get a piece of coax with an "F" connector on one end and then the open braid and center conductor on the other end. Use a multimeter and you will get either 13volts for horizontal polarity and 17 volts for vertical polarity I believe. A card has enough power to drive a motor no problem at all. If you can use your card to watch video on the sat your on and it switches from V to H okay chances are nothing wrong with card.

When I first got my card (ss2) I couldn't get the motor to work either and it turned out I didn't have the latest drivers. Once I loaded new drivers she took off like a shot.

I am ashamed to ask, but the center wire is positive right? I am going to wire some gel cells I have together and make a eighteen volt supply to use up on the roof. I got the latest drivers from twinhan and have installed and tested voltage at the card-- 4 volts!! No change ever. got to be a bad card. I've only got a 350 watt supply in my pc, but that should not effect open circuit voltage at the card. Thanks for the reply to this begginner. Chris

Make sure in the program you are using that you have enabled the voltage out... and just double check you have connected to the correct output of the card and not the pass through connector. The card does not output voltage untill you start your DVB program. Just hooking up a battery to the cable will not turn the motor. There is a constant voltage going to the motor in and then to the LNBF. You need the control signal to tell the motor to turn. From the card you have going to the motor the power for the motor and LNBF (LNBF is controlled by the voltage level) and the control signal for the motor. On the same cable traveling in the opposite direction you have the signal from the LNBF. (all on the same cable) With the 1020a card you can hear the relay click when the card starts up. I do not know if the 102G also has a relay or not.

The motor I have has manual buttons on it, so I hooked a power supply to it today and was able to move the dish just fine. Also, I used a little cheap satellite finder and fine tuned my dish. The meter was showing that I could get good signals, so I know the motor and lnb work. Then I took my computer apart and switched PCI slots that the twinhan was in. Now the card is running the motor just fine--but I am not getting any sat signals! By the way, yesterday I hooked this card up to my dishnet dish, which I know is pointed righ and works, and got no signal. Any more ideas? I really appreciate all the help.

Check your settings for the LNBF. For the dish network it should be LO 11250 (circular polarity LNBF), for a standard Linear LNBF it should be 10750. With these two types of LNBF's the LNBF does not use the 22KHz signal. However, the 22KHz signal can be used to control switches between your receiver and the LNBF. If you have a universal then LO-1 9750 22KHz off and LO-2 10600 22KHz on. With this type of LNBF, the 22KHz signal controls the band of the LNBF.

Thanks to everyone for the suggestions. In the end, it's obvious the card is no good.
I set the LNB as Larry1 suggested and a complete scan east to west showed no variation in signal at all. 65% signal with no quality at all. The card is on it's way back to the e-bay seller in California. I attempted contact with him three times with no response. It has a paypal buyer guarantee, so I know I'll get my $ back. Bought a new card from Sadoun. It comes in tommorrow. That's all, goodnight.

damage card

A damage card(works OK with horizontal polarization and no signal with Vertical), I sepouse is because the card do not send the voltage(11-14V) to LNB.
I would like to know wish part in the circuit can be damage, can any body help me with some schematic, or any help....

I had used the card in another PC, same softwares and same Card,

Twinhan1020A card

sorry for my english...

I'll buy all broken Twinhan cards that still get detected by windows but show no signal. PM me if you are interested.

Caution , only connect or dis-conect the coax from Cerds , receivers or LNB / LNBF with the power off .

Be aware , as you go from east to west , sweeping the sky , the elevation constantly changed . The only time signal strength means anything is when you tweek the dish direction , elevation or tweek something on the LNB / LNBF and tweek for max signal strength .

On DVB , signal strength alone does not get a picture .

I will relate how I was able to fine my first FTA sat - AMC 4 . It is at 101 degrees , same position at DTV's main sat .

I strapped a DTV LNBF on my 30" dish , took an old DTV receiver & TV outside & hooked everything up . Then tweeked untill I hot the barker channel , 100 , on DTV .

Took the DTV LNBF off & installed a linear Ku LNBF . Hooked this up to the sat card , did a little tweeking and bam , there was AMC 4 .

May be better to start out FTA with the dish stationary . Get some experience before you start messing with the motor .

Installing & tweeking a motor is a whole other discussion . PM me if I can help .
