keeny Posted February 11, 2009 Share Posted February 11, 2009 Hi, i;ve got a cm6800 pelco matrix controlling pelco leagcy recievers via rs422 D protocol. I know the matrix will control upto 16 units but when i conect upto 8 or 9 units i start to lose control over some of the camera's. Pelco say that i should have around 3.6vdc on the line which i have from the matrix, but the recievers are putting out 4.6vdc. Has anybody else encounted this problem. Thanks Link to comment Share on other sites More sharing options...

Thanks I've got a pelco 6800 matrix but via coaxitron and 2 wire 485 D via a distribution unit via a digital sentry remotely. If you can get 7 with no problem surely its a line length issue. Pelco Code distribution unit and split it., Link to comment Share on other sites More sharing options...
