Enova DGX Audio Insert/Extract Boards

Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Reinstalling an AIE Board
To reinstall an AIE Board:
1.
Enova DGX 32
– 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 AIE slot.
Or
Enova DGX 8/16 /64
– 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 AIE 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. (For placement of AIE boards in the Enova DGX 64, see page 18).
2.
Begin pushing the AIE Board into the AIE slot until the extractor handle starts to engage the metal extractor plate
(the extractor handle moves into its folded position).
When the extractor handle starts to lift, flip the handle toward the center of the board until it snaps into its folded
(locked) position, which firmly seats the board.
3.
Insert and tighten the screw (removed previously) that holds the board in place.
4.
Enova DGX 32 only
– When wiring is complete and functionality is checked, replace the connector numbering
plate that was removed previously.
5.
Re-apply power to the enclosure.
Important:
If for any reason an I/O expansion board slot is left empty, be sure to attach a blank plate to cover
the empty slot prior to re-applying power to the enclosure.
Enova DGX 64 Only - AIE Board Numbering Overlays
The Enova DGX 64 can hold up to eight AIE Boards (four on the upper rear of the enclosure and four on the lower rear).
The AIE Boards in the upper slots work in conjunction with the Input Boards; the AIE Boards in the lower slots work in
conjunction with the Output Boards.
Because all AIE boards are numbered 1 through 16, overlays are provided to simplify AIE connector wiring on the
Enova DGX 64. The overlays provided include: two each for the faceplates for connectors 1-16, 17-32, 33-48, and
49-64. The numbers on the overlays (when installed per the instructions below) directly correlate to the input and output
connectors.
Important:
The orientation of the AIE Boards in the right AIE slots places the lowest connector number
for these boards on the far right (e.g., the overlay for the board in the top right slot will read left-to-right as
48 though 33).
Note:
The audio connectors will need to be removed before applying the overlays.
To apply overlays to AIE Board faceplates:
1.
Check the numbering on the overlay to determine which board it applies to (see numbering in FIG. 76 on the next
page).
2.
Peel the backing off the overlay and discard the backing.
Tip:
For Step 3, start at the screw end and work across to the extractor handle end.
Caution:
The AIE Board has an EMI (Electromagnetic Interference) gasket along one edge of the faceplate.
Handle the boards carefully to avoid dislodging or damaging the gasket on the board being installed 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 32 and between the input and output slots on an Enova DGX 8/16/64.) An AIE Board can only
be installed in an I/O expansion board slot.
