Quick guide for tbs6909_v6
If you are using quad LNB, you can directly connect the 4 cables to the 4 ports of TBS6909.
If you want to lock TPs, the Tuner will automatically select an appropriate input. For example
(Notes: adapter0 ~ adapter 7 are the 8 tuners of tbs6909):
-lock VH frequency to adapter0, adapter1, adapter2, adapter3 and adapter4, then the driver will
create virtual and dynamic links between those 5 adapters of the Linux kernel and 5 of the
demodulator cores of TBS6909 will route them all to Input1. That means in this case 5 of the TBS
6909 demodulator cores will take the signal from the tuner attached to the Input1.
- lock HL frequency to adapter5, then the 6th demodulator core of TBS6909 will be virtually and
dynamically connected to adapter5 by the driver and the core itself will take signal from the
tuner attached to Input2
- lock HH frequency to adapter6 and adapter7, then the rest 2 demodulator cores of TBS6909 will
be virtually and dynamically connected respectively to adapter6 and adapter7 by the driver and
the cores itself will take signal from the tuner attached to Input3
In some case multiswitch have more than one satellite input, need to choose the satellite first, then you
can use this mode . It will be selected satellite by sending Diseqc command.
In this mode, if input 0 to input 3 has at least an active input then all tuners can get lock, for example:
If we have a VH signal connected to input 1 come from satellite B, use dvblast to scan the channel:
dvblast –f 12538000 –s 41250000 –v 13 –a 0 –S 2
it means that the VH port is choose satellite B, the other 7 tuners all can get the satellite B VH signal.
If we have a HL signal connected to input 2 come from satellite A, use dvblast to scan the channel:
dvblast –f 11080000 –s 43200000 –v 18 –m psk_8 –a 3 –S 1
it means that the HL is choose satellite A, the other 7 tuners all can get the satellite A HL signal.
If you have four kinds active signal connected to correct 4 inputs, then you can get all VL, VH, HL, HH signal.
