The ReadyNAS Pro 6 has an serial port at RS232 level.

First tried to connect with an USB to TTL adapter. No luck. After some more reading and searching on the internet i just tried to connect with an USB to RS232 adapter. With positive results!

Counting from the USB ports:

• 1 – GND  (pin 5 on RS232 / DB9 adapter)
• 2 – TX (RX / pin 2 on RS232 / DB9 adapter)
• 3 – RX (TX / pin 3 on RS232 / DB9 adapter)

1. Use PuTTY or Minicom and configure it with: 9600n8.
2. Hookup an USB keyboard to the ReadyNAS. (i use an usb port on the backside)
3. Power On the ReadyNAS, see PuTTY of Minicom showing the device booting up ! 🙂 (printscreen follows)
4. With the USB keyboard you can hit F3 and enter the BIOS.
5. Screen information will by sent to PuTTY or Minicom.

Note, there is also an VGA pin header on the main board. I will try that later, because i have to order some parts. (SUB-D 15 female for an flatcable, and an 16 pin flatcable connector)
