The eight switch positions are laid out as illustrated below:

3.6.1 Node Address

The first six switch segments of the DIP switch (with respect to the SW2 circuit board
marking) are used to set the IoG node address. The node address is determined by the
mathematical sum of the bit values of all switches that are in the "ON" position. As an
example, in the illustration above, the "2", "4", and "8" bit value switches are in the
"ON" position, therefore the node address for the IoG would be
The available node address range is 1 through 63.
