Thank you very much for your quick response,
I haven't been able to get connected at all with UART when turning on the NVR once UART is connected to TTL device the the serial monitor I only get error device can not connected and drop the serial connection with the UART adapter
However when I turn the NVR on whilst connected to UART the pc plays the sound as if to say a device has been connected/disconnected then the error appears.
I wonder if the UART pins are incorrect ? Used a multimeter to check and according to the images and my testing I have the correct tx and Rx and gnd pins so I'm stumped
Any guidance on checking UART connection to the main board would be appreciated. Thank you
I'll also try and get some images tonight of my connections
Thank you again
