Connecting to the serial port
|

=============================
|
||||
|
||||
If you don't need a serial console you can ignore this section. If you're
|
||||
using a KBL NUC and you need a serial console, you'll need to prepare
|
||||
an RS232 cable to connect to the KBL NUC serial port header, as shown
|
||||
below:

||||
If you don't need a serial console you can ignore this section.
|
||||
|
||||
Neither the APL or KBL NUCs present an external serial port interface.
|
||||
However, the KBL NUC does have a serail port header you can
|
||||
expose with a serial DB9 header cable. You can build this cable yourself,
|
||||
referring to the `KBL NUC product specification
