I have a D9900 DCM with several DVBS reception cards in it (DCM-DRD-4SAT4CI). Each of these cards has 4 satellite cable ports in it. My intention is to use it to receive TV from the Astra satellites located at 28.2deg East, as listed on this page: http://en.kingofsat.net/pos-28.2E.php.
All of these transponders have vertical or horizontal polarization, and my understanding is that this means the LNC requires a polarization voltage (13v or 18v). To provide this on the D9900 config UI, it seems I have to enable LNC 'bias' on each port.
My problem is that it will only allow me to enable bias on ports 1 & 2 on each card, which means I can't get ports 3 & 4 to lock onto a transponder.
Does anyone know if there is any way to configure ports 3 & 4 to receive TV from these Astra satellites?
