LED 1 to LED 8/13:

These green LED’s indicate the signal status of the RS-422/485, RS-232, and LTC

channels. Selectable modes accommodate signal presence indication of input data,
output data, or both. Selectable modes of signal status indication are described in
section 4.2.3 of this manual. LED designations are as follows:

The 7707DT-GPIO provides additional status indicator modes, where LED1 through
LED8 describe the states of the respective GPI or GPO channels.

CONTROL:

This yellow LED is no longer considered by recent code versions, and if installed,
should be disregarded by the user.

4.2.

CARD-EDGE DISPLAY AND CONTROLS

Additional signal and status monitoring is provided via the 4-digit dot-matrix display located at the card-
edge. The card-edge pushbutton and toggle-switch are used to navigate through the display menu. Figure
4-2 provides a quick reference to the display menu structure.

Pressing the pushbutton advances the display to the next menu level. The toggle-switch may then be used
to move up or down through selections of that menu level. Select

BACK

to return to the previous menu

level.

If a specific menu selection has a configuration value associated with it, then this may be changed using
the toggle switch. Pressing the pushbutton will apply the displayed value and return you to the previous
menu level.

The most recent user selection will be maintained in non-volatile memory in the event of power loss to the
module.
