Developer Board and Interfaces Description

• An RF cable with an MMCX connector is connected to the external antenna connector. Connect the RF cable’s MMCX
connector to the MMCX connector of the g20 by pushing it in until it clicks. This connects the g20 to the antenna.
3.3.2 USB Driver
If you are using a g20 with a USB driver, you must set the USB jumper (P300), located next to the USB connector, in order to
indicate that the g20 and not the Developer Board is providing the USB driver.
Connect the USB jumper (P300) between pins 1 and 2.
For more information on the USB jumper, refer to “Configuration” on page 14.
3.3.3 External Connectors
Place the cover back on the Developer Board and connect the following external connectors.
3.3.3.1 Power Supply
Make sure the Developer Board power switch is off before connecting the power supply.
Figure 9. Developer Board Power Switch and Adapter Connector
Connect the power adapter to the Developer Board adapter connector (J230), which is labeled Power on the cover of the Devel-
oper Board. Plug the adapter into a wall outlet.
3.3.3.2 PC Connection
USB and RS232 serial interfaces are available for PC communications. If a PC connection is required, connect either a RS232
cable with a male D-type connector to the RS232-1 labeled UART1 connector (J350), or a USB cable with a B-type connector
to the USB labeled connector (J300).
The g20 Developer’s Kit includes the necessary RS232 and USB cables.
3.3.3.3 Audio Devices
Connect the headset, which includes a headphone and a microphone. You can instead connect the speaker and microphone,
which are optional accessories.
Note
The g20 Developer Board can also be powered by an external DC power supply or battery cell. These options are
described in “Configuration” on page 14.
