1. Introduction
The GV200 is a powerful GPS Locator designed for vehicle tracking or asserts tracking. With superior receiving sensitivity, fast TTFF (Time to First Fix) and Quad-Band GSM frequencies
850/900/1800/1900, its location can be monitored in real time or periodically tracked by a backend server or other specified terminals. The GV200 has multiple input/output interfaces which can be used for monitoring or controlling external devices. Based on the integrated
@Track protocol, the GV200 can communicate with a backend server through the
GPRS/GSM network to transfer reports of Emergency, Geo-fence boundary crossings, Lower
Battery or scheduled GPS position along with many other useful functions. Users can also use
GV200 to monitor the status of a vehicle and control the vehicle with its onboard relay output.
System Integrators can easily setup their tracking systems based on the full-featured @Track protocol.

3.3.3. 5V Output
PIN 19 is named as VOUT which can drive a controlled 5V output for user. Please note that if user wants to drive a 5V output, GV200 must be supplied by external power. In default, 5V output is disabled, user can use AT commend to enabled 5V output. The max drive current of
VOUT is 0.25A. Queclink device will reboot. Please note that reboot do not change any firmware parameter. Confidential

3.3.6. Ignition Control
DOUT1/2/3 can be used to control ignition key. They are Open-Drain type with no internal pull-up resistor which also be used to control a relay. It means that the user has to connect a pull-up resistor or a relay coil between the DOUT1/2/3 pin and any positive voltage (32V max.) to generate a correct output. The DOUT1/2/3 pin can drive a continuous current of
0.2A.

3.3.9. Digital Input with Interrupt
DIN2 and DIN3 are digital inputs which have interrupt. DIN2 is negative trigger and DIN3 is positive trigger.
The example connections are same as showed in chapter 3.3.7.
DIN2 is also recommended to support panic button function and the connection is showed as follow.

3.3.10. Analog Input
3.3.10.1. Resistance-type Sensor
The PIN 3/5/7 are used for analog to digital converter. GV200 can support different type sensors such as resistance-type and capacitance-type due to the differences between the three seconds, which means the burst on voltage input may not be detected.
Confidential
AIN1 (PIN 3) is designed to support some resistance-type sensors and there is an internal pull-up resistor (100K Ohm) on its channel. Due to the internal pull-up resistor, user can connect resistance-type sensors directly between analog inputs and AGND. The follow figure is the example connection of AIN1 with NTC resistor. The recommended value of NTC resistor is 100K@25℃.

Capacitance-type Sensor
AIN2 (PIN 5) and AIN3 (PIN 7) are designed to support capacitance-type sensors. In default
GV200 only support capacitance-type sensors which voltage range is 0 ~ 2.7V. If user wants to use the capacitance-type sensors which voltage range is out of 0 ~ 2.7V, a level transfer board must be used between capacitance-type sensors and GV200. The follow figure is the

If the digital output is used to drive a relay, a catch diode is showed across the relay coil, this is necessary to prevent damage to the digital output when the relay is turned off. Many modern relays come with this diode pre-installed internal to the relay itself. If the relay has this diode, insure the proper relay polarity connected is used. If this diode is not internal, it should be added externally. A common diode such as a 1N4004 will work in most

3.5. Audio Interface
There is a differential output for speaker and a signal-ended microphone on GV200. Please note that the PIN 1 is analog ground and should not be used as a power ground. GV200 has an audio amplifier internally, so it can drive a louder speaker directly. It is recommended to connect an 8 Ohm speaker to speaker interface, and an electret microphone is also recommended.

Please note there are some recommendations about microphone:
1: Use an electret microphone with a sensitivity of -42±3dB/Pa @ 2V（not less than -44±3dB） and impedance of 2.2kΩ.
2: Two filter capacitors (10pF (0603) and 33pF (0603)) are recommended to build into microphone by vendor. These two capacitors could largely suppress coupling TDD noise from RF interference.
3: MIC /AGND should be a couple of differential traces, not be close to power supply signals.

3.6. UART Interface
There are two UART interfaces on GV200 which are named as UART1 and UART2. UART1 is used for configuration and firmware downloading. UART2 is used to communicate with external devices like CAN Bus module and RFID reader. PIN 13 is a control signal which is named as data terminal ready (DTR). When the GV200 is sleeping, a high level on DTR will wake up UARTs of GV200.
Please note the UART interfaces are all RS232 level. For RS232 level, valid signals are plus or minus 3V to 15V and the -3V to +3V is not a valid level. 3V to 15V correspond with logic
0 of TTL level, -3V to -15V correspond with logic 1.
