i need some help here ...
i want to have an antenna tracker and i found a code for arduino but the problem i have is, that the code needs rssi ( signal strength ) input from two different video receivers and i already have an expensive diversity receiver ( 2 antennas ) which has a special tracker port for an expensive antenna tracker. this tracker port puts out different information, amongst others the rssi signal i need for the cheap tracker.
this is the stuff the tracker port puts out , i copied it from another document, the guy who posted it doesnt seem that sure but noone corrected him yet
My discovery of "Tracking link output".
Please correct me if you have other information.
Tracker Link output:
Yellow (Video) - Video output
White (Audio L) - ???
Red (Audio R) - RS232 TTL Telemetry output
Sends 6 byte message with frequency: ~30Hz (probably related to video frame rate)
Message example (HEX):
AA 03 75 79 96 55
AA - Sync byte
03,04 - ??
RSSI 2 Bytes 75 - Channel1 79 - Channel2, ~12 - maximum signal, ~79 - no signal
96 - Power voltage 11v-8F 12v-9B 10v-7F
55 - end of message
and this is a link to the software i wanted to use for my arduino trackerhttp://www.michael-heck.net/bilder/diversityrc305/rssi.pde
can anyone please help me , or at least show me, how i can get my rssi1 and rssi2 values from the tracker port?
unfortunately i do not know how to do that
