So I just need a UART device to connect to it. I looked around and I had both a BeagleBone and a Raspberry Pi near me with UART. So I grabbed the BeagleBone and pulled the front panel USB cable off the NVR (this used the same connector as the UART connector), in the process I broke the connector (it was glued in place) but that was fine. I plugged it in, use the voltmeter and checked the voltages with respect to ground (the chassis), the rear most wire was 5V (power), the front most was 0V (ground), and the middle two were 3-ish.
