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.
