Setting the Board ID

If you install two or more boards on one personal computer, assign a different ID value to each of the
boards to distinguish them.
The board IDs can be set from 0 - Fh to identify up to sixteen boards.
If only one board is used, the original factory setting (Board ID = 0) should be used.
Setting Procedure
To set the board ID, use the rotary switch on the board. Turn the SW1 using, for example, a standard
screwdriver, to set the arrow to the board ID.

Setting the Supply Voltage

Some PCI bus slots on the PC may supply power only at 3.3 V, where 5 V power is not available. In that
case, change the supply voltage of the board before use.
Setting method
To set the PCI bus slot supply voltage, use the on-board jumper.
When 5 V power is supplied, set the JP1 to the 2-3 connected state (factory default). If 5 V power is not
supplied, set the JP1 to the 1-2 connected state.
