When the {FAST I/O} softkey is pressed on the Main Diagnostics Menu
screen, the Fast I/O screen appears. “FAST I/O” appears at the top to
identify the screen, along with the “SETUP MODE” message indicating
that the control is in setup diagnostics mode.
Figure 15A.15 shows an example of the Fast I/O screen.

OUT 09 11 13 15
The screen shows connector CN17F, which is the Fast I/O connector
number. It is followed by the four input terminals (01, 03, 05, and 07) and
the four output terminals (09, 11, 13, and 15).
If an input or output is “ON”, its terminal number appears in inverse video.
This is a real time display, and its response is limited only by delays in
screen updates.
Pressing the exit softkey (up arrow) at any time displays the Main
Diagnostics Menu screen.
