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 knob to set the board ID as shown
below.

Setting the Terminating Registor
You can select whether to insert a terminator (terminal resistor) in the differential input section.
Select whether to insert the terminator depending on the system to be used.
Setup Method
To select whether to insert the terminator, use the DIP switches (SMC-4DL-PCI : SW2 and SW3,
SMC-8DL-PCI : SW2 - SW5) on the board.
Set SW2 and SW3 according to the figure shown below.
