Choose desired source module for the relay output number (1-3) being config- ured.

The list of modules will depend on the in- stalled modules.

e.System DIO

Selecting “System DIO module…” from the “System & Network I/O Module Con- trols” menu (Figure 3-25) provides sub- menus for setting up the output configurations of the DIO signals. The DIO board is comprised of 8 digital inputs and 24 digital outputs. Functions of sup- ported analyzer modules can be attached to each input and a signal to each output. Further detailed information about the DIO board is contained in its own manual.

If there is no DIO module installed in the analyzer, a corresponding message will be displayed instead of the menu.
