zhtway 0 Posted June 15, 2012 Hello, My work have G3 AutoDome EnviroDome & Specto DVR-16TH. G3 has RS-232 (TXD, RXD, Gnd) and Spectro has RS-485 (D+, D-, Gnd). How could I match up TXD to D+ or other way? Picture can be viewed through BNC from Dome but control didn't work. What are the default baud rate, priority..values..for G3? What protocol does G3 use? Thanks zhtway Share this post Link to post Share on other sites
