nikey22 0 Posted November 15, 2018 @tomcctv This DVR has a 9-pin RS 232 port on the back. Can we use this with a null modem cable to connect it directly to a computer for telnet access? (console access) for example if there is a need to update firmware a different way? I noticed in your other post you mentioned that all newer DVRs don't have telnet function anymore, I haven't tried yet with this model. Share this post Link to post Share on other sites

nikey22 0 Posted November 16, 2018 quick question: If you install a firmware with date: 080601, can you return to firmware date: 171229 if you wanted to? In other words can you go back to an older firmware; will it allow it? thanks. Share this post Link to post Share on other sites
