May I assume that 0x10 is the I2C address?

According to the datasheet, 0x0c means:
- pulsed current limiting
- max. LNB current: 650mA [1]
- tone controlled by DSQIN pin [2]
- LLC 0V
- VSEL 18V
- Chip enabled

0x04 is the same, except
- VSEL 13V

[1] Did you check the specs of your card whether it can supply
    550mA or 650 mA current at the LNB input?
    If there is no information, it might be better to limit the current
    to 550mA. -> Set bit 6.
[2] Could someone please tell me whether DSQIN or EXTM are used on the
    Nexus 2.3? On the older cards DiSEqC was done by the av7111.
