Sounds familiar. Most of Synology ARM-based NAS have this layout:

2 4 6 
1 3 5
^

1 3.3V 
2 GND 
4 TX 
6 RX

With Synology ARM-based NAS, they use the same layout above consistently.

So you should look for the pin 1 marking. It's either a rectangle or an arrorw ^ pointing to pin 1. And then orient yourself whether it is facing in for facing out from the motherboard.

Help with UART Pins of DS415+

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?
