PTZ programming

Are you using Pelco 'D' or 'P' protocol?

ACK data is there to return responses to the control to let it know that the camera is accepting commands properly and responding to them. It can also be used to simply confirm that the control codes were sent properly - for example, an incorrect code sent to the camera might not generate an ACK, whereas a properly formed command would return a specific ACK; your controller or software can view this to confirm that communication is happening.

I would expect any documentation on the protocol you're using would explain the ACK codes. A Pelco SDK would probably be helpful. There's a bit of info here as well:

I have never used daynapel. D86 series. Did you mean DynaPel? There are too many variables and not enough information to assist you. You aren't saying what you are using to control the PTZ or how it is wired. Pelco has more than one protocol.. If this is some custom built gear you have then you might ask the guys at Sennetech about it.

Thank you very much for ur prompt response!

I am using Pelco D protocol/RS432. Can any one send me the query commands for PTZ?

PTZ is Dynapel D interceptor.

RS432???

Dynapel won't provide them?

Pelco can... under the Tech Tips section of their website, the following document, "How to Obtain and Use Pelco Protocols": ftp://
