RJ45 Ethernet connector
The Ethernet port is auto-sensing and self-configuring (auto-MDI/MDIX) to
allow connection to either a crossover or straight-through connector.
Power supply Jack connector 12 V
The product can be powered by any 12VDC power supply (minimum 1A). It
handles polarity inversions.
Power supply Molex connector 5/12 V
The product can be powered by an ATX 12V power supply (mini 1A)
If necessary, it could be also powered by 5V (mini 2.5A). To allow this, you
need to move R6/R26 resistors towards R5/R25 positions. WARNING : In this
case the product is neither short-current protected nor polarity protected.
WARNING : The product must be powered by only one source. Do not
use both power connectors together.
C-Key connector (J9)
You can plug a C-Key (removable memory).
The "flat" side of the C-Key must match the
"flat" drawing on the board
(see red lines on the picture)
