GV300 User manual 1. Introduction The GV300 is a powerful GPS locator designed for vehicle or asset tracking. It has superior receiver sensitivity, fast TTFF (Time to First Fix) and supports Quad-Band GSM frequencies 850/900/1800/1900, its location can be monitored in real time or be periodically tracked by a backend server or other specified terminals. The GV300 has multiple input/output interfaces that can be used for monitoring or controlling external devices.

GV300 User manual 3. Getting Started 3.1. Opening the Case Figure 3. Opening the Case Insert the triangular-pry-opener into the gap of the case as shown below, push the opener up until the case unsnapped. 3.2. Closing the Case Figure 4. Closing the Case Place the cover on the bottom in the position as shown in the following figure. Slide the cover against the direction of the arrow until it snapped.
GV300 User manual 3.3. Installing a SIM Card Open the case and ensure the unit is not powered (unplug the 16Pin cable and switch the internal battery to off position). Slide the holder right to open the SIM card. Insert the SIM card into the holder as shown below with the gold-colored contact area facing down taking care to align the cut mark. Close the SIM card holder. Close the case. Figure 5. SIM Card Installation 3.4. Installing the Internal Backup Battery Figure 6.
GV300 User manual 3.5. Switch ON the Backup Battery To use the GV300 backup battery, the switch must be at the ON position. Switch on the case and ON/OFF position are shown below. Figure 7. Switch and ON/OFF position Note: The switch must be on the “OFF” position when shipped on an aircraft. 3.6. Installing the External GPS Antenna (Optional) There is a SMA GPS antenna connector on GV300. The GV300 will automatically detect and use an external antenna when connected.
GV300 User manual Figure 8. GPS Antenna of GV300 3.6.1. GPS Antenna Specification Table 5: GPS Antenna Specification GPS antenna: Frequency: 1575.42MHz Bandwidth: >5MHz Beam width: >120 deg Supply voltage: 2.7V-3.3V Polarization: RHCP Gain: Passive: 0dBi min Active: 15dB Impedance: 50Ω VSWR: <2 Noise figure: <3 3.7. Power Connection PWR (PIN12) / GND (PIN6) are the power input pins. The input voltage range for this device is from 8V to 32V.
GV300 User manual 3.8. Ignition Detection Table 7: Electrical Characteristics of Ignition Detection Logical State Electrical State Active 5.0V to 32V Inactive 0V to 3V or Open Figure 10. Typical Ignition Detection IGN (Pin3)is used for ignition detection. It is strongly recommended to connect this pin to ignition key “RUN” position as shown up. 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.
GV300 User manual Figure 11. Typical Digital Input Connection 3.10. Analog Inputs There are two analog inputs on GV300, the analog input voltage range is from 0 to 2.8V. The following diagram shows the recommended connection. Figure 12. Typical Analog Input Connection Note: PIN 15 is an multifunction pin: it can be configured as a digital input or an analog input.
GV300 User manual 3.11. Digital Outputs There are three digital outputs on GV300. All are of open drain type and the maximum drain current is 150 mA. Each output has the built-in over current and recovery PTC fuse Figure 13. Digital Output Internal Drive Circuit Table 7: Electrical Characteristics of Ddigital Outputs Logical State Electrical Characteristics Enable <1.5V @150mA Disable Open drain Figure 14.
GV300 User manual Figure 15. Typical Connection with LED Note: 1 - OUT1 will latch the output state during reset. 2- All outputs are internally pulled up to PWR pin by a diode. So no external flyback diode is needed when the output is connected to an inductive load. 3.12. Device Status LED Figure 16.
GV300 User manual Table 8: Definition of Device status and LED LED Device status LED status GSM (note1) Device is searching GSM network Fast flashing (Note3) Device has registered to GSM network. Slow flashing (Note4) SIM card needs pin code to unlock. ON GPS chip is powered off OFF GPS sends no data or data format error. Slow flashing GPS chip is searching GPS info. Fast flashing GPS chip has gotten GPS info. ON No external power and internal battery voltage is lower than 3.35V.
