I did not understand, you say that there are other dip in the head? There are 4 more dip in the base for the protocol, but nothing else in the head

@ Horizon I had already tried to reverse the data of 485, but no operation I confirm that the Siemens console keyboard works well (the console has only Siemens protocol)

I tried with two Korean dvr but does not work I'm sure you can connect to a DVR different from Siemens, where wrong?

No, but il problem is con Siemens my tests are on the bench in the laboratory with 50 cm PTZ wired No external contro, only PTZ command from DVR I wrote that I used the siemens console keyboard only needs to verify that the PTZ speedDome Siemens CCDA1435 worked well with PTZ command. But I have to command it only with the DVR 4NSYS

I had already first time tried in off and on position I had already written... I do not know what else to try

Yes is correct I tried with and without resistance This is DVR connector: This is Speed dome connector with DVR work fine This is Siemens CCDA1435 Speed Dome camera connector that does not work with DVR I exhaustive ?

Tnx Fiona my English is very little, but you were right, that's correct This: http://www.4nsys.com/Default0.asp Dvr with pelcoD speed-dome work fine, but not work with siemens speed-dome although protocol, connection is correct

Connection is RS485 This speeddome work in Siemens proprietary protocol with keyboard Siemens CKA4820, ok. I have to work speed dome (changing protocol from Siemens to Pelco-P) only with DVR 4NSYS using RS485 serial connection, no use keyboard consolle, only DVR PTZ command. But also the parameters (DVR and SpeeDome) are correct and equal not work

Thanks for your response. Ok for what concerns the control console in the Pelco dome. But why not work the dome instead Siemens CCDA1435-DN is able to use the protocol PelcoP as DVR that should command it? Speed, protocol, connection and id are correct, because it does not work?

Hi to all I have a speed-dome Siemens CCDA1435-DN and a console Siemens CKA4820, no problem if used together. How i do to connect and PTZ control the speed-dome Siemens CCDA1435-DN to a DVR 4NSYS with the protocol PelcoD or P and the same speed (9600) i can not make it work, i tried different protocols and speeds but nothing to do The second question, is possible use the console Siemens CKA4820 with a camera PelcoD?
