Differential pair works as serial differential receive/transmit data lines.
5V/SB5V
5V supply for external devices. SB5V is supplied during power-down to allow
wakeup on USB device activity. Protected by 1.0A current limiting circuit for each
USB port.
6.4 DC Power Jack Connector (Vin Ext.)
The DC Power Jack Connector (Vin Ext.) connector must be used to supply the board with +9V~+24V. Maximum
allowed current is 5A.
Warning: Hot Plugging power supply is not supported. Hot plugging might damage the board.
Notes:To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
