Synology Serial Console
My old Synology DS918+ is powered off and collecting dust. I figured I should be able to install mainline linux on it and turn it into a shell server with a lot of disk.
iFixIt documents how to take the plastic shell off in order to get access to the system board itself. Basically, unscrew the two screws at the corners in the back of the unit, and slide the main (disk cage) forward. You can then pull the metal disk cage and system board apart. It's really easy.
Modders Inc also has a good post of which components are used. What caught my eye is in this picture the 6-pin, unlabeled connector on the bottom right of the system board.
The pin order thanks to sharpen mask on that image above is:
5 3 1
6 4 2
Thanks to "darrend", he correctly mapped out part of the pins:
Pins
1 3.3V
2 GND
4 TX
6 RX
For the serial connection via picocom/minicom, you want: 115200 8N1. You are then greeted with the boot messages:
