2.5.12. ioctl FE_ENABLE_HIGH_LNB_VOLTAGE

2.5.12.1. Name

FE_ENABLE_HIGH_LNB_VOLTAGE - Select output DC level between normal LNBf voltages or higher LNBf - voltages.

2.5.12.2. Synopsis

int ioctl(int fd, FE_ENABLE_HIGH_LNB_VOLTAGE, unsigned int high)

2.5.12.3. Arguments

fd

File descriptor returned by open().

high

Valid flags:

• 0 - normal 13V and 18V.
• >0 - enables slightly higher voltages instead of 13/18V, in order to compensate for long antenna cables.

2.5.12.4. Description

Select output DC level between normal LNBf voltages or higher LNBf voltages between 0 (normal) or a value grater than 0 for higher voltages.

2.5.12.5. Return Value

On success 0 is returned, on error -1 and the errno variable is set appropriately. The generic error codes are described at the Generic Error Codes chapter.
