Each configuration is identified by a unique satellite_id. + * + * In order to make things as easy as possible for users, there are a set of + * defaults hardcoded into the library covering the majority of LNB types. When + * these are used, the standard back-compatable sequence defined in the DISEQC + * standard will be used - this will suffice for _most_ situations. + * + * UNIVERSAL - Europe, 10800 to 11800 MHz and 11600 to 12700 Mhz, Dual LO, loband 9750, hiband 10600 MHz. + * DBS - Expressvu, North America, 12200 to 12700 MHz, Single LO, 11250 MHz. + * STANDARD - 10945 to 11450 Mhz, Single LO, 10000Mhz. + * ENHANCED - Astra, 10700 to 11700 MHz, Single LO, 9750MHz. + * C-BAND - Big Dish, 3700 to 4200 MHz, Single LO, 5150Mhz. + * C-MULTI - Big Dish - Multipoint LNBf, 3700 to 4200 MHz, Dual LO, H:5150MHz, V:5750MHz. + * + * However, for the power user with a more complex setup, these simple defaults + * are not enough. Therefore, it is also possible to define additional SEC + * configurations in an external configuration file. This file consists of multiple + * entries in the following format: + * + * [sec] + * name=<sec_id> + * switch-frequency=<switching frequency (SLOF)> + * lof-lo-v=<low band + V + frequency> + * lof-lo-h=<low band + H + frequency> + * lof-lo-l=<low band + L + frequency> + * lof-lo-r=<low band + R + frequency> + * lof-hi-v=<high band + V + frequency> + * lof-hi-h=<high band + H + frequency> + * lof-hi-l=<high band + L + frequency> + * lof-hi-r=<high band + R + frequency> + * config-type=<none|power|standard|advanced> + * cmd-lo-v=<sec sequence> + * cmd-lo-h=<sec sequence> + * cmd-lo-r=<sec sequence> + * cmd-lo-l=<sec sequence> + * cmd-hi-v=<sec sequence> + * cmd-hi-h=<sec sequence> + * cmd-hi-r=<sec sequence> + * cmd-hi-l=<sec sequence> + * + * The sec_id is whatever unique value you wish. If it is the same as one of the hardcoded defaults, the configuration + * details from the file will be used instead of the hardcoded ones. + * The switch-frequency (or SLOF) indicates the point seperating low band frequencies from high band frequencies. + * Set this value to 0 if there is only one frequency band. + * The lof-lo-v is the frequency adjustment for V + low band (i.e. less than SLOF), or is used if switch-frequency==0. + * The lof-lo-h is the frequency adjustment for H + low band (i.e. less than SLOF), or is used if switch-frequency==0. + * The lof-lo-l is the frequency adjustment for L + low band (i.e. less than SLOF), or is used if switch-frequency==0. + * The lof-lo-r is the frequency adjustment for R + low band (i.e. less than SLOF), or is used if switch-frequency==0. + * The lof-hi-v is the frequency adjustment for V + high band (unused if switch-frequency==0). + * The lof-hi-h is the frequency adjustment for H + high band (unused if switch-frequency==0). + * The lof-hi-l is the frequency adjustment for L + high band (unused if switch-frequency==0). + * The lof-hi-r is the frequency adjustment for R + high band (unused if switch-frequency==0). + * + * config-type indicates the desired type of SEC command to use, it may be: + * none - No SEC commands will be issued (frequency adjustment will still be performed). + * power - Only the SEC power is turned on. + * standard - The standard DISEQC back compatable sequence will be issued. + * advanced - The DISEQC sequence described in the appropriate sec cmd string will be used. + * + * The cmd-<lo|hi>-<v|h|l|r> describes the SEC cmd string to use in advanced mode for each of the possible combinations of + * frequency band and polarisation.
