Note
DISEQC
TM
(DIGITAL SATELLITE EQUIPMENT CONTROL)
The DiSEqC
TM
system is used to control systems with extended
control functions. DiSEqC
TM
uses a serial, bi-directional transmission
process with a master and one or multiple slaves. The data bits are
generated with pulse width modulation of the already existent 22 kHz
carrier and are superimposed with 600 mV
SS
of the LNB remote
feeding voltage. The digital code words are composed of 8 data
bits and one additional parity bit for the recognition of transmission
errors. Multiple code words form one DiSEqC
TM
command. Code
words are entered in hex code:
The MSK 125 can send signals based on DiSEqC
TM
1.0 but cannot
receive them.
