Figure 6 shows the minimum configuration for NMEA outputs and commands sent

via an RS232 interface based on the GPS/GLONASS module A5100-A using a

passive antenna and with backup voltage on V_BAK. Before removing Vcc, it is

highly recommended to put A5100-A into hibernation mode either by ON_OFF pin or

software command

. Otherwise, high current drain will die out the backup battery in a short period of

time.

Figure 6: Minimum configuration A5100-A with Vbak

Remarks:

• External antenna input impedance is 50 Ω. Match as close as possible.

• A battery back-up circuit for the RTC (Real Time Clock) should be considered

(see chapter: “10.6 Battery Back-up”)
