Note: Node address 0 is used for messaging between nodes and must not be used.

A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch 1 is the Least Significant Bit and switch 8 is the Most Significant Bit. The switches have the following decimal values: switch 1=1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128. Turn off the switches and add the values of the off switches to obtain the correct node address. (On=0, Off=1)

Note: This jumper can be enabled for systems with a faster I/O bus requiring the NIC to "latch" a memory address and the transfer width and preserve them until the NIC can complete thememory transfer. In other words if your system has a faster than average (>8MHz) I/O bus speed you might need to enable this option.
