[QUOTE="Captain Jack, post: 1154473, member: 243342"] This is from my archives.... ---------------- Hello, I try the same thing as you, i.e. motorizing the dish from a PACE MSS 1000. As you, i posted a question about signal and protocol on AV2. I analysed the pin 12 on AV2 and extracted this information : Each time you change program, you get a serial transmission of 9 bits coded as this : Pulse of 3us(5 V) followed a delay of 64us for a "0" and 86us for a "1". The stream is organized as follow D0, D1, D2, D3, D4, D5, D6, D7, SAT D[0:7] : number (binary order) of the selected satellit (for 1 to 63) SAT equal 0 if you disabled the option "positionner pol.") equal 1 for Horizontal polarisation (if option enabled) equal 1 " Vertical " " " " When you force the receiver to stand by, all the bits are "1" Beware of the state of the pin 8 : If pin 8 = 0 at power on, the receiver will output the satellit number on pin 12 If pin 8 = 1 (12 V) at power on, the reciever will send a stream like this : 200 ms at 1, 30 ms at 0, 10 ms at 1, 10 ms at 0 and then 60 ms at 1. This bitstream is used for downloading configuration between receivers. [/QUOTE]
