quick guide for tbs6909
www.tbsdtv.com
Mode 1:
If you are using quattro LNB, you have 4 cables (V/L,V/H,H/L,H/H), connect the right one to
TBS6909 like the above picture ( input 0- input 3 should be connected to V/L,V/H,H/L,H/H
respectively).
Mode 2:
If you are using quad LNB, you can directly connect the 4 cables to the 4 ports of TBS6909.
Mode 3:
If you are using C band or Ku band single, then two inputs are enough, you just need to connect
the cables to input 0 and input 2.
When you are using TBS6909, TBS6909 has 8 Tuners&Demodulators, but it only has 4 inputs,
because it has a multiswitch inside, defining 4 inputs to receive 4 single polarity
signals(Input0=VL; Input 1=VH;Input 2=HL;Input3=HH).
If you want to lock a 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
When you lock DVB-S2 TPs, you need to set the modulation, but this setting is not necessary for
DVB-S. Some examples as below:
For dvblast:
dvblast -f 10988000 -s 41250000 -v 13 -m psk_8 -a 0
For mumudvb config:
#DVB-S
#The DVB card number
card=2
freq=12648
srate=29500
pol=V
