2.2.4.4 Power Supply Connector
The board has the following power supply connector:
• External Power Supply – the board is powered through a 12-19 V DC connector on the back
panel. The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter) and
2.5 mm/ID (inner diameter) plug, where the inner contact is +19 (±10%) V DC and the shell is
GND. The maximum current rating is 3 A.
NOTE
External power voltage, 12-19 V DC, is dependent on the type of power adapter used.
