1. Introduction
The GV200G 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 GV200G has multiple
input/output interfaces which can be used for monitoring or controlling external devices.
Based on the integrated @Track protocol, the GV200G 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 GV200G to monitor the status of a vehicle and control the
vehicle with its external relay output. System Integrators can easily setup their tracking
systems based on the full-featured @Track protocol.

Please install the power like following.
Figure 6: Example of power connection
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, GV200G must be supplied by external power. In def ault , 5V
output is disabled, user can use AT commend to enabled 5V output. The max drive current of
VOUT is 0.25A.

3.3.5. Ignition Detect
The PIN 14 is DIN1 (Positive trigger). Its electrical conditions are:
Table 8: Electrical conditions of ignition detect
Logical State Electrical State
Active 5.0V to 32V
Inactive 0V to 3V or Open
It is strongly recommended to connect this pin to ignition key to support the power saving
function when the vehicle is off.
Figure 8: Ignition detection
Another easy way is to connect PIN14 to a power output in the fuse box of the vehicle which
is only enabled after the vehicle is ignition on. For example: the power output for radio FM.
3.3.6. Ignition Control
DOUT1/2/3/4 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 DOUT1/2/3/4 pin and any posi tive volta ge (32V
max.) to generate a correct output. The DOUT1/2/3/4 pin can drive a continuous current of
0.2A.

3.3.8. Digital Input without Interrupt
The DIN1 and DIN4 are digital inputs which do not have interrupt. DIN1 is positive trigger
and DIN4 is negative trigger. The sample rate for this digital input is 2 to 24 se conds. Please
note the high sample rate will also result in high power consumption.

3.3.9. Digital Input with Interrupt
DIN2 and DIN3 are digital inputs which have interrupt. DIN2 is negative t ri gge r 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.
Figure 12: Example connection of panic button
3.3.10. Analog Input
The PIN 3/5/7 are used for analog to digital converter. GV200G can support different type
sensors such as resistance-type and capacitance-type due to the differences between the three
analog inputs. Please note it is an average value based on the sample rate from 2 to 24
seconds, which means the burst on voltage input may not be detected.
3.3.10.1. Resistance-type Sensor
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
GV200G 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 GV200G. The follow
figure is the example connection of AIN2/3 with capacitance-type sensors.

User also can connect a power source directly to AIN2/3, the voltage limitation is same as

3.5. Audio Interface
There is a differential output for speaker and a signal-ended microphone on GV200G. Please
note that the PIN 1 is analog ground and should not be used as a power ground. GV200G 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 GV200G 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 GV200G is sle epi ng, a hi gh le ve l on
DTR will wake up UARTs of GV200G.
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.
