The device number of the selected MTB Panel I/O device appears under
the “MTB PANEL I/O” heading. This will be a decimal number from 00
to 03.
This screen displays the input and output pin assignments that correspond
to the input and output connectors on the MTB Panel I/O module.
If an input or output pin is “ON”, it appears in inverse video. This is a real
time display, and its response is limited only by delays in screen updates.
The following abbreviated symbols may appear:
PW = power connection
GD = ground connection
If more than one MTB Panel I/O device is on the I/O Ring, a diagnostics
screen for each of these devices can be displayed. To display a diagnostics
screen for the next MTB panel I/O device on the ring, press and hold the
[SHIFT] key and press the [DOWN-ARROW] key.
Pressing the exit softkey (up arrow) at any time displays the Ring I/O
Menu screen.
