Physical Installation OEM DragonFly Board Model Kit
The OEM DragonFly Board Kit differs from the chassis model tremendously. The chassis
model is modular and is recommended for most applications. The Board model should be
used only when the DragonFly needed to be embedded in the system because of space or
when there is no other choice. There are two main reasons for this:
1)
The RF sections must be isolated from each other for the unit to work correctly.
2)
The high density of the part placement and the size constraints of the boards do
not make it conducive to easy design implementation.
Installation and Design Instructions
NOTES: Refer to the .stp files for exact measurements.
1)
Design installation locations
a.
The boards are stacked upon one another using a specifically design ledge
and a board to board connector.
b.
The DF cavity design should follow the .stp files with regards to the RF
isolation, RF Board screw placements, the ledge and screw placements for
the encoder board, and the cover.
c.
Using CAD design tools
–
design the chassis or the cavity placement for the
DF according to the .stp files.
d.
The Wi-Fi antenna must not be covered by metal if you are using this
method for configuration
2)
Install the RF Board
a.
Install the heatsink pad on Analog Devices IC as shown in the figure below.
b.
Place the RF board in the cavity with the RF isolation on the bottom
c.
Fasten to cavity using the 11 M1 screws provided in the kit.
3)
Install the Encoder board.
a.
Stack the encoder board on top of the RF board to align the board-to-board
connectors
b.
Gently push the boards together so the edges push to the ledge and the
board-to-board connector fully engages.
c.
The Encoder board is held in place by the lid.
4)
Lid Placement
a.
Gently place the lid on top, compressing the encoder board down.
b.
Fasten the lid in place using the 8 0-80 screws provided.
5)
Place the thermal pad to align the through-holes with pattern in the DragonFly.
6)
Make or purchase cables need to run DragonFly. Cable that may need to be made:
a.
Power and RS 232 serial cable
