AIE Audio Insert/Extract Boards

Enova Digital Media Switchers - Hardware Reference Manual
Setting the DIP Switches
IMPORTANT:
When an AIE connector is set to insert audio, audio on the corresponding video signal will always be
replaced with the input from the AIE connector. When the AIE connector does not have a valid audio signal to insert, "no
signal" is the input that will be inserted – resulting in no sound.
The individual AIE connectors on the AIE Board must have their DIP switches set according to how the audio for each
connector is to be used in the system.
Each board has two DIP switches per AIE connector with the corresponding AIE connector number displayed vertically
between the switches, labeled "Channel Setting"(FIG. 91):
The DIP switch on the left is used for enabling or disabling the extract/insert functionality. The DIP switch on the right can
be set to either "extract audio from" or "insert audio onto" the signal routed on numerically corresponding standard input
or output connectors.
NOTE:
Write down the setting for each connector before reinstalling the AIE Board into the Enova DGX enclosure. This will
make verifying correct audio switching (see page 182) easier.
IMPORTANT:
When disabling extraction/insertion functionality for connectors on the AIE board, use the DIP switch settings
"Disable/Extract"; do not use the settings "Disable/Insert."
Enable/Disable DIP Switches
Located on the left (see blue rectangle in FIG. 91).
To enable, flip left. Enable must be selected for the insert/extract function to work.
To disable, flip right. Disable turns off the insert/extract function for that port.
Extract/Insert DIP Switches
Located on the right (see red rectangle in FIG. 91).
To extract audio, flip left. The AIE connector will pull the embedded audio signal off the corresponding standard
input or output connector’s signal (the embedded audio remains intact on the HDMI signal).
To insert audio, flip right. The AIE connector will insert the connected audio signal onto the corresponding standard
input or output connector’s signal.
NOTE:
When shipped from the factory, the DIP switches are set to "Enable" and "Extract."
Reinstalling an AIE Board
CAUTION:
AIE Boards have an EMI (Electromagnetic Interference) gasket along one edge of the faceplate. Handle
boards carefully to avoid dislodging or damaging the gasket on the board being handled and the gasket on the
adjacent board or blank plate.
CAUTION:
Do not try to install an AIE Board in any of the standard input or output board slots. (Standard board slots are
indicated by the numbers on the numbering plate that is above the slots on an Enova DGX 3200 and between the input
and output slots on an Enova DGX 800/1600/6400.) An AIE Board can only be installed in an I/O expansion board slot.
1.
Enova DGX 3200
– With the board’s extractor handle in the extended (unlocked) position, line up the board’s edges
on the board guides that are along the top and bottom of the expansion slot.
- or -
Enova DGX 800/1600 /6400
– With the board’s extractor handle in the extended (unlocked) position, line up the
board’s edges on the board guides that are along the left and right of the expansion slot. Note that boards on the
input side have guides at the top of the slot and that guides for boards on the output side are at the bottom of the
slot due to their reversed orientation in the enclosure.
