samsung shc-750 pc control

[brandx99 0]

Hi there,

I have a samsung sch-750 analog camera that I would like to control from a PC. The manual is not very clear on what protocol the camera is using. Also, it kind of contradict itself about if its using rs-485 or rs-232. I've joined some screenshot attachments from the manual.

 

The manual specify the RS-485 configuration(parity,data bit ect...) and then remote pinout seems to be for rs232 because of the TX and RX(see first image). RS-485 pinout is usually a+ b- not TX RX.

To had to the confusion, in the specs , it say : RS-232C -> Built-in(see second image). Lastly, they provide a table with different command without specifying the protocol(see third image). I've checked on the web and does not look like pelco-D protocol.

 

So my questions are:

-Should I connect the camera to a rs-232 or rs-485  usb dongle?

-Could tell me what protocol is being used (pelco-D , pelco-P ect...) if you recognize it?

 

Thanks for your help.
