PTZ programming

[Naresh850]

Hello Sir,

I would like to program the PTZ camera which is daynapel D86 series.

I successfully control the PTZ camera with Pan left/right, tilt up/
down, zoom in/out with pelco protocol. But I cant understand the
acknowlegement data from PTZ.

I would like to interpret acknowledgement data from PTZ. I haven't
understand protocol for acknowledge data from PTZ.

Could anybody help me in this regard to understand what PTZ
acknowledge?

what is acknowledge data tells us?

Thanks in advance for your commnets.

Regards,
Naresh

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: http://www.codeproject.com/KB/cs/PelcoPDinC.aspx

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.

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

"Requests for one or more of these protocol documents should be made via
