2. Get Started
2.1. Open the Case
Open the Case
Insert the triangular-pry-opener into the gapof the case asshown above,and push the
opener upuntil the case is unsnapped.
2.2. Close the Case
Close the Case
Place the cover onthe bottom inthe position asshown inthe figure above.Slide the cover
against the direction ofthearrow until it snaps.

2.3. Install a SIM Card
Open the case and ensure the unit is not powered (unplug the 16Pin cable and switch the
internal battery to the OFF position). Slide the holder right to open the SIM card holder.
Insert the SIM card into the holder as shown below with the gold-colored contact area facing
down. Take care to align the cut mark. Close the SIM card holder. Close the case.
SIM Card Installation
2.4. Install the Internal Backup Battery
Backup Battery Installation
NxtG-V has an internal backup Li-ion battery.

2.5. Switch on the Backup Battery
To use the NxtG-V backup battery, the switch must be in the ONposition. The switch on
the case and the ON/OFF position are shown below.
Switch and ON/OFF Position
Note:
1. The switch must bein the “OFF” position when the NxtG-V isshipped on an aircraft.
2. When the switch isin the “OFF” position, the battery cannot becharged or discharged.
2.6. Install the External GPSAntenna
There isa SMA GPS antenna connector on NxtG-V. The NxtG-V will automatically detect
and use an external antenna when connected.

2.7. Power Connection
PWR (PIN11)/GND (PIN6) is the power input pin. The input voltage range for this device is
from 8V to 32V. The device is designed to be installed in vehicles that operate on 12V or 24V
systems without the need for external transformers.
Typical Power Connection

2.8. Ignition Detection
Electrical Characteristics ofIgnition Detection
Logical status Electrical characteristics
Active 5.0V to 32V
Inactive 0V to 3V or open
Typical Ignition Detection
IGN (Pin3) is used for ignition detection. Itisstrongly recommended toconnect this pin to
ignition key “RUN” position as shown above.
An alternative toconnecting to the ignition switch isto find a non-permanent power source
that is only available when the vehicle isrunning,for example, the power source for the FM
radio.
IGN signal can beconfigured tostart transmitting information tothe backend server when
ignition ison,and enter the power saving mode when ignition is off.
2.9. Digital Inputs
There are three general purpose digital inputs onNxtG-V.They are all negative triggers.
Electrical Characteristics of the Digital Inputs
Logical status Electrical characteristics
Active 0V to 0.6V
Inactive Open
The following diagram shows the recommended connection of a digital input.

Typical Digital Input Connection
2.10. Analog Inputs
There are two analog inputs onNxtG-V,and the analog input voltage range is from0to
16V. The following diagram shows the recommended connection.
Typical Analog Input Connection
Note:
PIN 15 is a multifunction pin: it can be configured as a digital input or an analog input.

2.11. Digital Outputs
There are three digital outputs onNxtG-V.All are of open drain type and the maximum
drain current is 150 mA. Each output has the built-inover current PTC resettable fuse.
Digital Output Internal Drive Circuit

Typical Connection with Relay

Typical Connecon with LED
Note:
1. OUT1 will latch the output state during reset.
2. Many modern relays come with a flyback diode pre-installed internal to the relay itself. If
the relay has this diode, ensure the relay polarity is properly connected. If this diode is not
internal, it should be added externally. A common diode such as a 1N4004 will work in most
circumstances.
2.12.Device Status LED
