Communication Node
When multiple Spirit systems are being used together on an RS-422 serial
communication link, each system must have a unique identification
number (node number) to identify itself to the network. To set the
communication node number for the Spirit system, scroll down to the Set
Communication Node selection on the maintenance screen and press
ENT. The communication node selection screen will be displayed as
shown. Press F3 to scroll through the available node numbers. When
using an Inova torch height control system with the Spirit, the
communication node feature must be disabled. To disable the
communication node, press F3 until “disabled” is displayed in the node
number selection box. When the desired selection is highlighted, press
ENT.
