2.2 Installing the Hardware

To properly connect the HC15 module and all accessories to the DSB75 Support Board follow these

steps:

• Check that all switches of the DSB75 Support Board are set as described in Chapter 5. See also

Figure 4 which shows an exploded view of all parts.

• Connect the one end of the mini antenna cable to the Hirose U.FL connector located on the mod-

ule's top side.

• Mount the HC15 module upside down onto the 50-pin board-to-board connector of the adapter

board. Use the supplied M2 screws and nuts to screw the module to the adapter board.

• Attach the adapter board to the 80-pin header located on the DSB75. Take gentle care that all pins

are aligned correctly, then press down evenly on the adapter board until it is firmly seated. Use the

supplied M3 screw and bolt to secure the adapter board to the DSB75 Support Board.

• Connect the other end of the mini antenna cable to the the Hirose U.FL connector of the DSB75.

• Screw the external antenna (MiniMag) into the SMA connector on the DSB75. To improve the

antenna performance use the metal plate for grounding. The external antenna should be positioned

in the center of the metal plate.

• Connect the Western plug of the handset to the Western jack on the DSB75.

• Connect the power cables to the red (BATT+) and black (Ground) connectors of the DSB75.

• Plug the USB cable to the computer's USB port and to the USB port of the DSB75. Press the IGT

key of the DSB75 to switch on the HC15 module. Start your Windows XP computer.

• See Section 2.3 to continue.
