    PTZ and RS-232C

    Thank you scottj. I don't recieve the unit yet but as I ask the supplier they don't know about VISCA cable and I think it is because most of IP camera users will mostly use proprietary PTZ control via camera's web interface. And if it is include I don't think it is long enough for my use. The distance I need is about 10 meters and I wonder what type of cable and connector/converter should I use. The only information I can search on the web is how to convert RS-232 to RS-485 but I can't find any info about how to connect RS-232 to RS-232 itself. I can only find RS-232 to RJ45 but it has 8 wire out but the camera accept only 3 wires. Can I just match RX, TX, and GND wire and ignore the rest or I should need another converter?

    PTZ and RS-232C

    It is a sony SNC-RZ25P, a PTZ IP camera that also has analog output and connect to my geovision dvr system. The camera only has RS-232C interface but not RS-485 and I have no idea how to connect it. Another question is that, the camera use VISCA protocol, what type of PTZ should I set in geovision? Many thanks.
  3. I have a PTZ camera and it's only has RS-232C interface. How can I connect my PC's com port to camera's RS-232C port (9 wires from com port but only 3 slot on camera ie. Rx, Tx, and Ground)? Do I need another kind of converter?
