V-SEC (Vario-Satellite Equipment Control)
V-SEC provides unidirectional communication between satellite receivers
and peripheral components in a satellite receiving system and serves to
control intelligent multiswitches with several inputs, coaxial relays or
rotation systems.
V-SEC uses 8-bit data transfer by pulse width modulation of the 22 kHz
carrier frequency. There is 8-bit data transfer from the test receiver to the
peripheral equipment through the existing coaxial cable. The V-SEC
control signals are assigned to the components by destination addresses.
After output of the V-SEC data, standard signals of 14 V/18 V and 0/60
Hz/22 kHz are still available. Input of the code word is in hexadecimal
code..
