4.4.1. DISEQC command for locking satellite signals.
TBS6508 DVB-S2/S mode, one input is used for 2 tuners , which are divided into four
groups for better understanding.
group 1 (tuner 0 & 1)
group 2 (tuner 2 & 3)
group 3 (tuner 4 & 5)
group 4 (tuner 6 & 7)
Each group has a master tuner and a slave tuner, they use the same Diseqc together,
but only the master tuner can issue the Diseqc , the second slave tuner can’t send
command to Diseqc.
So, if you need to use Diseqc , you make pay attention to the order here, only after
the master tuner in each group sent command to the Diseqc and locked the program
first , the second tuner can lock programs.
