pilotos 0 Posted May 29, 2014 Hello , my camera is a Hikvision analog , and i bought a USB to rs485 adapter in order to have access to the cameras OSD menu from my laptop.....I have installed the drivers (Prolific) the Comm Port is number 4 , baud rate at 9600 , and select Pelco D protocol.... From the adapter i connect T-/A and T-/B to the cameras D+ D- accordingly , and nothing else......the camera is set as a Pelco D , baud rate 9600.... I am using a software PTZ Controll in order to access the OSD menu , and i select RS 485/422 , Pelco D etc........... ...........but the osd menu doesn't appear on screen......I am not sure if i have done the wiring connections correct so i am attaching 2 photos and i would really appreciate your guidance into this.....it seems that there is not communication............ Thanks Nikolas. Share this post Link to post Share on other sites
gb5102 0 Posted May 30, 2014 have you tried to reverse the polarity of the RS485 connection? try swapping the D+ and D- wires also on most cams using Pelco-D you would use Preset 95 to enter the OSD Share this post Link to post Share on other sites
