Hot swap from USB powered mode to battery powered mode is bounded by presentbattery voltage level. It is recommended to apply hot swap only if a battery is fully charged.Figure 11: Battery charge status LED4.2 GNSS RF inputThe C099-F9P board should be used with the antenna supplied with the kit. If another active antennais used, be aware that the RF input has a bias output designed to supply 3.3 V DC with a 70 mAmaximum current load. A DC block is advisable if the board is connected to a signal distributionscheme or GNSS simulator to prevent any potential shorting of the antenna bias.Figure 12: GNSS antenna connectorWhen using the supplied antenna it is advisable to use the ground plane provided. Otherwise ensurethat there is an adequate ground plane, e.g. by mounting in the center of a metallic car roof.Figure 13: The supplied GNSS multi-band antennaRed battery charge LEDSMA GNSS antenna connector
