I have seen serial adapters for sale but need like a wire interface rather than a plug as im not using a pc based DVR Ryan This is what we would do. Bring the PTZ onto the bench and connect it to the DVR to confirm you have PTZ operation. Purchase a pair of 232 to 485 convertors and wire them into the cable circuit so that you have DVR to 232>485 then wire to 485>232 then PTZ and check that this works. Then install the radio into the circuit replacing the wire between the convertors and check for operation. Only then install on site.
