Thread: Two DVB-S cards one motor how to let the other card to move the motor?

Now one question why this invacom has 4 outputs (two linear, two circular) are this ones copies of each one, in other words are this inputs receiving the whole range of frequencies?


now about using a STB for moving the motor, the problem here is that when the card will tell the receiver to move?

Using the diplexer according to pendragon in this scenario I must be very carefull that both cards don't try to move the motor right?


guapoharry not sure about Digicipher II on Circular but Tubos DVB-S yes they are.

1. Yes, the Invacom outputs are each the complete freq range. 2 separate linear outputs and 2 separate circular outputs.

2. Yes, you don't want both cards to be trying to access the motor.

3. I think that DC-II remark was partly tongue in cheek, but I have on occasion picked up an ITC DC-II transponder with the linear lnbf on the skywalker.

You can command an STB to turn the motor using its Remote. PC card tuners won't turn it in this scenario, and neither will control the STB. Invacom has 4 independent LNBFs packaged in a common plastic case.

When using the Diplexers, since each of your PC cards will power 2 (out of 4) independent LNBs, you may get by without putting any of your cards in Standby when switching channels. But both cards will scan in most scenarios the same sat, unless you setup your motorized dish as on my avatar.

Do you watch now channels from both cards in 2 separate windows? Using what Sat. Viewer package?
When turning motor via one card, you may need to first put in Standby mode another one, but try it and share your finding.

Well basically what I want is to tune channels and if this channel are located in another satellite then the Diseqc command should move the dish to that desired satellite.

So using a STB will make me change first the channel on the PCI dvb card and then tell the STB to move the satellite
