Notes: 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)

BLOCK DECODE

16KB

Pins 1 & 2 Closed

 

128KB

Pins 2 & 3 Closed

Note:A 16-bit VGA adapter typically decodes base memory in 128KB blocks. If you are installing the NIC in a system with such a card, you many need to set the NIC block decode size to 128KB. If you set the block decode size to 128K all other adapters in the system must also utilize 128KB decode.
