Mhakala 0 Posted November 27, 2011 I have a set of Costar 2500h cameras one is a 2500h and the rest are 2500hx. I do notice that the 2500h has switches SW1 for the termination, but the 2500hx models have an additional set of switches next to SW1 switches. What do these do? the documentian i have have seen does not tell me what these are for? Share this post Link to post Share on other sites
