Spectral Inversion
There are four supported modes of spectral inversion:
•
On – forces the tuner to stay with spectral inversion. The tuner will not check for
spectral inversion automatically
•
Off – forces the tuner to stay without spectral inversion. The tuner will not check for
spectral inversion automatically
•
On Both – tries spectral inversion first and then attempts to automatically check
spectral inversion periodically – Recommended Default Configuration
•
Off Both – tries non-spectral inversion first and then attempts to automatically check
spectral inversion periodically
LNB 22 KHz Tone
Enables or disables the LNB 22 KHz tone to the LNB for remote LNB and switch control.
Pilot
Enables or disables the Pilot for DVB-S2 mode of operation only.
Roll Off
The expected filter roll off of the carrier the receiver should be looking at. This parameter only works for
DVB-S2 mode, since DVB-S mode uses a fixed roll off of 35%.
The valid roll offs in DVB-S2 modes are:
•
20%
•
25%
•
35%
DiSEqC
Enables sending and receiving DiSEqC commands as are supported in DiSEqC mode 1.2. The valid
configuration settings for DiSEqC mode are:
•
Off
•
Mode A
•
Mode B
•
Mode C
•
Mode D
Switch
Enables or disables the ability to switch to a backup carrier. If set to disabled, the CMR-6000 will not
attempt to switch to a backup carrier.
Switch Time
The number of seconds the unit should wait before attempting to locate the backup carrier. Setting the
switch time to a setting of 0 (zero) causes the backup frequency to be disabled.
