GUIDE TO INSTALLATION AND OPERATION
12 | DAP-1781
3 Local control using the Densité frame control panel
Push the SELECT button on DAP-1781 card edge (see Section 1.6) to assign the local control panel to
operate the DAP-1781. Use the control panel buttons to navigate through the menu, as described below.
All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all
interaction between the cards and the outside world. There are no operating controls located on the cards
themselves. The controller supports remote operation via its Ethernet ports, and local operation using its
integrated control panel.
The local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed can
be accessed by opening the front door of the frame.
The panel consists of a display unit capable of
displaying two lines of text, each 16 characters in
length, and five pushbuttons.
The panel is assigned to operate any card in the
frame by pushing the SELECT button on the front
edge of that card.
• Pushing the CONTROLLER button on the
control panel selects the Controller card itself.
• The STATUS LED on the selected card flashes yellow
The local control panel displays a menu that can be navigated using the four pushbuttons located beneath
the display. The functionality of the pushbuttons is as follows:
[CTRL]
Selects the controller card for status monitoring and adjustment
[+] [–]
Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button
once enables modification of the value using the [+] and [–] buttons; a second push confirms the
new value
[ESC]
Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC]
causes the parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC]
does not exit the menu system. To exit, re-push the [SELECT] button for the card being
controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the
selected card’s STATUS LED reverts to its normal operating mode.
3.1 Status LED and Report
The status monitor LED is located on the front card-edge of the DAP-1781, and is visible through the front
access door of the DENSITÉ frame.
This multi-color LED indicates module status by color, and by flashing/steady illumination, according to the
following chart. The state flashing red is the highest error level; the green state represents no error.
The chart also indicates fault reporting for this card on the DENSITÉ frame’s serial and GPI interfaces.
