Dear Customer,
Thanks for using TBS6909, TBS6909 is a powerful DVB-S/S2 octa tuner card, and there is some
information you need to know before using.
There are three ways of signal input for TBS6909, which are shown as the picture below:

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

coderate=auto
common_port=1234
autoconfiguration=full
modulation =8PSK
For Tvheadend:
Set the “Delivery System”to DVBS2 and Modulation.
If you want to use DiSEqC with TBS6909, you need to change the mode to normal mode, one
input for two tuners, two tuner use the same satellite, you can do it like this:
Create text file "/etc/modprobe.d/tbs.conf" with line:
options tbs_pcie-dvb tbs6909_mode=0
