This switcher allows the signal reception from four independent Universal LNBs
(coming from 4 different satellites) on a single receiver.
As it is possible to observe in the attached scheme, there are "OPTION" and
"POSITION" switchers in cascade. In order to switch it, will be necessary to send
an OPTION command and later a POSITION command that yields, therefore, a
total of 4 possibilities.
Note: the manufacturers usually assure the compatibility with the Tone-burst
commands (SAT A/B) so that the second stage can be switched as much using a
«POSITION A/B» command as using a «SAT A/B» command. This allows us then
to use the switcher like a Tone-burst type with 2 inputs and 1 output.
With the HD
incorporates a specific «OPT / POS»command:

These switchers are transparent to the LNB's (13V, 18V, 22 kHz) switching
commands. Then, once the satellite is chosen by means of the SAT command,
the corresponding LNB can be used in a normal way. (see Universal LNB).
