u2_storm 0 Posted September 11, 2015 Hello, I have an existing Mark Mercer dome (D150/D250 I'm not actually sure!) It's currently running though it's 7 presets and just keeps repeating.... The new DVR I've installed has the standard RS485 controller so Pelco-D/P etc Could anyone point me in the right direction at all? I'm looking at getting a USB>RS485 controller so that I can at least set it up via my laptop but I can't even do that yet! Many thanks! Share this post Link to post Share on other sites
sam10693 0 Posted September 24, 2015 Hi mate Depends on te age of the camera, exact model number would be useful also the type of camera block can help to identify weather it will or not. The older domes only did mercer 485 not pelco. Even the newer apex and vertex domes had lite and pro versions, the latter being the one that supported pelco. Hope this helps Sam Share this post Link to post Share on other sites
