DiSEqC (Digital Satellite Equipment Control)
The DiSEqC system is used to control systems with extended control
facilities. DiSEqC uses serial, bidirectional transmission with one master
and one or more slaves. The data bits are formed by modulation of the
pulse width of the available 22 kHz carrier and are superimposed with
600 mV
ss
of the LNB remote voltage. The digital code words are made up
of 8 data bits and one additional parity bit to detect transmission errors.
Several code words form a DiSEqC command. Input of the code words is
in hexidecimal code.

The MSK 24 can also transmit signals to DiSEqC 1.0 but it cannot
receive them.
