8.1.5 Analog Input (PIN6/PIN14)

8.1.5.1 Example – Detecting External Power Voltage
Input range: 0–6V
Voltage caculation formula: Input voltage = (AD x 6)/1024
0x0377=>887(decimal)=>(887 x 6)/1024 = 5.1972 V (Voltage)
0x02FB=>763(decimal)=>(763 x 6)/1024 = 4.4707 V (Voltage)

8.2 Installing GPS and GSM Antennas

GSM antenna
Connect the GSM antenna to the SMA connector which is labeled "GSM". The GSM antenna is non-directional, so you can hide
it in any place of a vehicle.
Connect the GPS antenna to the connector which is labeled "GPS". It is recommended that the antenna is facing up to the sky
and the antenna side with words is downwards. Secure the antenna by using double sided tapes.
Note: Do not install the GPS antenna at a place with metal.
