Help with UART Pins of DS415+ (1 reply)

I need the pinout for the DS415+ UART port.

I need to know the GND, TX, RX, and 3.3V pins, assuming I'm looking directly at the connector. The row of 3 pins closest to the motherboard is row 1 and the other row is row 2.

I've looked on several websites, but I can't find the exact pinout for the 415+, and Synology frequently changes this pinout from model to model.

Can anyone help me?
