SETUP INSTRUCTIONS
Standalone w/Display and Keyboard/Mouse
In this configuration, the board works more like a PC, totally free from any connection to a PC as
shown in Figure 7. It allows you to create your code to make the board do whatever you need it to
do. It will however require certain common PC accessories. These accessories and instructions are
described in the following section
Figure 8 - Desktop Configuration
Additionally an Ethernet cable can be connected for network access.

12
X15 QUICK START GUIDE
PLUG IN YOUR CABLES
ETHERNET
There are two ports on the Ethernet connector on X15. Plug
cable into either port. Notice the orientation of cable
insertion between the two ports in Figure 8.
Figure 9 - ETHERNET PORTS
HDMI
Plug in HMDI cable into P11 HDMI connector on the top edge
of the X15 board.
Figure 10 –HDMI PORT
ESATA
Plug in eSATA cable as shown in Figure 10.
Figure 11 –eSATA PORT

13
X15 QUICK START GUIDE
KEYBOARD AND MOUSE
To avoid using up multiple USB ports a Wireless keyboard and
mouse combination is preferred. The transceiver can be
installed in either USB port including P6 eSATA connector.
Figure 12 –Keyboard Transmitter
AUDIO
To playback and record audio, insert speaker cable into Audio
OUT jack of the X15 and an audio source into the Audio IN
jack.
Figure 13 –AUDIO JACKS
MICRO SD CARD
On the bottom edge of the X15 board, on the bottom side is
the micro SD card cage. I booting from SD card the micro SD
card is inserted as shown in Figure 12 with the top side facing
up. Change boot settings on J3-J4-J6 as shown in the next
section.

BOOT STRAPPING
J3, J4 and J6 can be strapped with Shunts for different booting options.
See Figure 15 for details.

PLUG IN POWER
Once all the needed cables are inserted, plug in the DC power
adapter into the P1 jack. This is a 2.5mm center contact and
requires a supply that comes with a 2.5mm jack or an adapter
to 2.5mm. See Table 1 for more info.
Figure 18 –DC IN JACK P1
POWER LEDS
Once the power plug is inserted in P1, the Power LED D41 will
light up.
Figure 19 –DC 12V LED
TURN ON HD MONITOR
Once power is connected, turn on HDMI monitor. Change
input to the HDMI port the X15 is connected to.

TURN ON X15 POWER
Though power is plugged in and the terminal is connected
there will be no activity observed on the terminal. LED D41
will glow.
To turn ON the X15 main power press the blue momentary
switch S1. This will cause LED D3 to glow showing that the
board power is ON.
Figure 21 –POWER LEDs
BOOTING
At this point the software present in eMMC
will start to boot and activity can be seen on
the terminal.

USER LEDS
During the botting process the user may notice that the user
LEDs will blink.

TESTING
DEBUG:
The Serial debug port on the processor is UART3 via a single 1x6 pin header. In order to use the interface a USB to
TTL adapter will be required. The header is compatible with the one provided by FTDI and can be purchased from
various sources. Signals supported are TX and RX. None of the handshake signals are supported. On the PC you will
see activity that will take you to login prompt.
Figure 25 - Terminal activity on the Tera Term
A few seconds after the board power is turned on, the image in eMMC will boot and the Debian desktop will soon
show up on the HDMI monitor.

ETHERNET
Assuming the Ethernet cable is connected to one of the ENET ports on the EPD-X15 a quick test can be performed
by pointing the mouse to the bottom left corner of the Desktop and clicking the Debian menu logo. From here
point to Internet Chromium Browser.
Figure 27 - Open Web Browser
The browser window will open and if there is an internet connection, the browser will go to the homepage.
Figure 28 - Browser opens to the home page
The second Ethernet port can be similarly tested by moving the cable from ENET0 to ENET1. See Figure 3
