Setting of MAC address

On LAN and TCP/IP, this circuit card can have the following addresses and ports.

MAC Address: 000032250xxxH (48 bits)

TCP Port Numbers: 16 port numbers of 1024 ~ 1039

The last 12 bits of MAC address must be set by switches SW0 and SW1 before starting up this circuit card.

(Ex.)

When MAC address is to be set to 000032250123H:

By dividing 12 bits into 4-bit units (refer to the table on the right side), and set the switches as shown below.

		SW0			SW1
ON	1 2 3 4 5 6 7 8		ON	1 2 3 4 5 6 7 8
3		2	1		0
