RO uint64
When a statistic has the output type uint64, the received data can be converted to variable double
type with the following C code:
unsigned long long StatisticData;
DtmResult Result = DtmReadInt64(DtmAddr, CategoryNr,
SettingNr, Index, &StatisticData);
double Statistic = double(StatisticData) / pow(2.0, 64.0);
4.5.8 DiSEqC send and receive options
The manageable items in category 0x93 can be used to send and receive DiSEqC message to/from
LNB’s, switches or motors. DiSEqC messages can contain as much data as required.
