justmejustme 0 Posted July 27, 2010 Hello, I have recently aquired a second hand gv250 card with 4 bnc but only 2 of the 4 port seem to work. I saw there is some software limitation... can I do a firmware update to use all4 channels or I just got screwed ...? thank you. Share this post Link to post Share on other sites
rory 0 Posted July 27, 2010 its probably the 2-channel card - GV-250-2 The other 2 ports will never work if that is the case. Share this post Link to post Share on other sites
