PRIMARY DISPLAY SYSTEM -ACCEPT, REJECT AND CANCEL SWITCH INTERFACE
General
The ACCEPT/REJECT/CANCEL switches on the captain’s and first officer’s glareshields give the flight crew control of uplink and downlink messages. The OPAS panel data concentrator units (PDCUs) receive requests as analog discretes and process them.

PRIMARY DISPLAY SYSTEM -CAPTAIN DISPLAY SWITCHING PANEL INTERFACES
General
An inboard display (INBOARD DSPL) selector and a heading reference (HDG REF) switch send analog discretes to the OPAS panel data concentrator units (PDCUs). The inboard display selector gives the flight crew control of the inboard display format. The heading reference switch gives the flight crew control of the compass heading reference on both the captain’s and first officer’s displays.

PRIMARY DISPLAY SYSTEM -INSTRUMENT SOURCE SELECT PANELS INTERFACE
General
The captain’s and first officer’s instrument source select panels (ISSPs) send analog discretes to the OPAS panel data concentrator units (PDCUs) to process. Each ISSP switch gives onside flight crew control for an alternate source display.
The PDS has automatic control when the ISSP switches are in the normal position.

PRIMARY DISPLAY SYSTEM -CURSOR CONTROL DEVICE INTERFACES
General
The cursor control devise (CCD) gets grounds from the panel data concentrator units. The grounds turn on lights to indicate which display the operator selected.

PRIMARY DISPLAY SYSTEM -DISPLAY SELECT PANEL INTERFACES
General
The display select panel (DSP) receives analog discrete data from the overhead panel ARINC 629 system (OPAS). The DSP sends analog discrete data to OPAS.
Inputs
The DSP receives a ground analog discrete from each OPAS panel data concentrator unit (PDCU). The DSP receives power from -2.7 to 5 vac.
Outputs
The DSP sends an analog discrete(s) to each OPAS PDCU when you make a mode and/or a display request.

PRIMARY DISPLAY SYSTEM -CENTER DISPLAY CONTROL PANEL INTERFACES
General
The center display control panel receives analog discretes from and sends analog discretes to OPAS.
Inputs
OPAS sends two analog discrete grounds to the center display control panel.
Outputs
The center display control panel sends an analog discrete when the DSPL CTRL switch is in the AUTO and ALTN position to OPAS.
The center display control panel also sends an analog discrete to OPAS when the operator uses the event record switch.
