= Tips, Tricks, Caveats =

FEL mode
The Emergency button on the right side triggers the FEL mode. The corresponding USB OTG is available on the extension board connector J4 and has the following pin out:
 * 1) VBUS
 * DM
 * DP
 * 1) USB-ID
 * 2) GND

LVDS-Display
Is connected over LVDS pins PD12-PD21 on LCD2 connector.

Device disassembly
Remove the back 4 screws. There is a hole on the bottom back housing were a screw driver could be placed to open it.

Locating the UART0 (J6)
There is a not assembled connector J6 marked on the right extension board which is connected to UART0 and has the following pin out:
 * 1) GND
 * TX
 * 1) VCC
 * RX

Locating the UART3/4 (CON2)
The connector CON2 has 2 RS485 UARTs connected.
 * 1) DBEL
 * 2) GND
 * 3) UART3-A
 * 4) UART3-B
 * 5) UART4-A
 * 6) UART4-B
