Connecting the EMS31 Evaluation Module to the DSB75
To properly connect the EMS31 evaluation module and all accessories to the DSB75 please
complete the steps listed below. The complete setup with the evaluation module mounted onto
the AH6-DSB75 Adapter and the AH6-DSB75 Adapter connected to the DSB75 is shown in
•
Ensure that all jumpers and slide switches on the DSB75 are set to their default positions
as shown in
and in
.
•
Attach the 80-pin header of the AH6-DSB75 Adapter to the 2x40-pin connector (X101/
X202) located on the DSB75. Take gentle care that all pins are aligned correctly, then press
down evenly on the adapter until it is firmly seated.
•
Remove the knurled nuts from the AH6-DSB75 Adapter.
•
Mount the EMS31 evaluation module onto the 80-pin board-to-board connector X120 of the
AH6-DSB75 Adapter.
•
Fasten the knurled nuts to secure the module to the AH6-DSB75 Adapter.
•
Use the small antenna cables to connect the U.FL RF connector for the main antenna on
the EMS31 evaluation module to the U.FL-R SMT connector on the AH6-DSB75 Adapter:
- for main antenna connect to X391.
•
Screw the external antenna to the appropriate SMA connectors on the AH6-DSB75
Adapter:
- Main antenna to X390
•
Insert the SIM card into the card reader located at the AH6-DSB75 Adapter.
Note: Do not use the SIM card reader of the DSB75 Support Board.
