shawndang 0 Posted February 20, 2014 I am trying to get text overlay to work with sam4s cash register and a dahua 16ch hybrid 960h dvr. I would like to use serial interface. I am open to using network sniffing as well. I know that the register is sending out text thru rs232 cause I tested it with VSI Pro. I need help with setting the text overlay on the dvr side and its settings. Share this post Link to post Share on other sites
