LNB Start.
Writing a one to this bit initiates an LNB signaling sequence. This bit is automatically
cleared to zero when the sequence is complete.
Note: Not available in manual LNB mode.
LNB DC Voltage Selection.
0 = 13 V (default)
1 = 18 V
Continuous Tone Selection.
0 = Normal operation (default)
1 = Send continuous tone
Note: Not available in manual LNB mode.
Tone Burst Selection.
0 = Unmodulated tone burst (default)
1 = Modulated tone burst
Note: For use in automatic LNB mode only. Use a 1-byte DiSEqC message for tone burst
More Messages.
0 = Normal operation (default)
1 = Indicates more DiSEqC messages to be sent
This bit is automatically cleared to zero when the sequence is complete.
Note: For use in automatic LNB mode only.
Message Length.
000 = No message (default)
001 = One byte
010 = Two bytes
011 = Three bytes
100 = Four bytes
101 = Five bytes
110 = Six bytes
111 = Longer than six bytes.
Notes:
