DiAngelo 0 Posted March 7, 2016 Who can help me with the serial pin layout from a DH-NVR2104-P? I Think it is where i placed the arrow and the numbers 1 - 4 Thanks Share this post Link to post Share on other sites
brebenac 0 Posted March 14, 2016 That kind of serial port has GND, Vcc, Tx and Rx. Considering you have a multimeter at hand, you can easy find the GND and the Vcc. And you're left with only 2 possibilities for the Tx and Rx. Good Luck! Share this post Link to post Share on other sites
