1. Introduction
The GV50LTA is a powerful GPS locator designed for vehicle or asset tracking. It has superior
receiver sensitivity, fast TTFF (Time to First Fix) and supports Dual-Band 4G-LTE B4&B13
Band, and its location can be monitored in real time or periodically tracked by a backend
server or other specified terminals. The GV50LTA has multiple input/output interfaces that
can be used for monitoring or controlling external devices. Based on the integrated @Track
protocol, the GV50LTA can communicate with a backend server through the 4G-LTE network
over which it transfer reports of emergency, geo-fence boundary crossings, low backup
battery or scheduled GPS position as well as many other useful functions. Users can also use
GV50LTA to monitor the status of a vehicle and control the vehicle by its external relay
output. System Integrators can easily set up their tracking systems based on the
full-featured @Track protocol.

2.3. LED Description
GV50LTA has two status LEDs which are CELL LED (Blue color) and GPS LED (Green color).
Table 4: LED Description
Note:
1. Fast flashing is about 500ms ON / 1sec OFF.
2. Slow flashing is about 500ms ON / 15sec OFF.
2.4. Power Connection
VIN(PIN3)/GND (PIN7) are the power input pins. 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/24V
vehicle without the need for external transformers.

2.5. Ignition Detection
IGN (Pin4) is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RUN” position as shown below.
An alternative to connecting to the ignition switch is to find a non-permanent power source that
is only available when the vehicle is running. For example, the power source for the FM radio.
IGN signal can be configured to start transmitting information to backend server when ignition is
on, and enter power saving mode when ignition is off.
Table 5: Electrical Characteristics of Ignition Detection
Figure 4: Typical Ignition Detection
OUT1/IN1 (PIN5) is a digital Output/Input connection on GV50LTA. It is of open drain type
and the maximum drain current is 150mA. The OUT1/IN1 (PIN5) can be used as a digital
Output and a (negative trigger) digital Input.

3.5. Install a SIM Card
Open the SIM case and ensure the unit is not powered (unplug the 7Pin cable 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 orange colour. Take care to align the cut mark. Then close the case.
Figure 3. SIM Card Installation
3.6. Switch on the Backup Battery
To use the GV50LTA backup battery, the switch must be in the ON position. The switch on the
case and the ON/OFF position are shown below.
Figure 4. Switch and ON/OFF Position
Note:
1. The switch must be in the “OFF” position when the GV50LTA is shipped on an aircraft.
2. When the switch is in the “OFF” position, the battery cannot be charged or discharged and
cannot be turned on.

GV50LTA isn’t registered to
the ISP.
Please register the GV50LTA
again and make sure the device
gets the correct MDN.
The signal is too weak;
GV50LTA can’t be
registered to the network.
Please move GV50LTA into
places with good LTE coverage.
Messages can’t be
reported to the backend
server by LTE.
The IP address or port of

GV50LTA if charger is
connected.
Disconnect charger, and try
again.
GV50LTA can’t get
successful GPS fixing.
The GPS signal is weak.
