Hi. Hwo has ecpiriance wth rs 485 ptz control camera by arduino. I use max485 adapter and scetch seems ok - oscilograms seem ok for A and B. But camera not react to FF 01 00 20 00 00 21 and
FF 01 00 40 00 00 41 .
Wich nuances may be there ? Any advise ?
Posting a link to the datasheet/technical manual might make more helpers interested.
Asking for hands on experince limits the numbers.
You should tell us which Arduino you are using and provide a drawing - hand drawn and photographed is fine - showing how you have connected your Arduino to the RS485 module and the PTZ head.
Also show us your sketch.
Those commands look like they may be using the Pelco protocol?
Yes - this is Pelco-d. I tryed nano and mega and different scetches and two tipe rs485 to TTL converters. Also just send codes manual from serial manitor - and I see that contact A and B oscilogram is present when I send comand- Now I thing that address or bout rate is not default - is it posibal to check default settings of camera by arduino - maybe some scan scetch ?
See above.
