k1lla 0 Posted November 17, 2006 I am using a pc based DVR using K-World card. I currently can control the PTZ speed dome using a RS-232/RS 485 adapter with Pelco D protocol. I have just purchased a Pelco CC1400HZ16-2 (built-in lens has a maximum zoom ratio of 128x). Will it be possible to control the zoom lens from the DVR or the PC on this new Pelco. I thought I saw some software from Pelco which will allow me to control it from the PC which would be fine, but how would I connect this? Is it possible to control 2 different cameras if one is rs422 and one is rs485? Share this post Link to post Share on other sites
