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.

3.3.6. 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.

3.3.10. Analog Input
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
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℃.

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
example connection of AIN2/3 with capacitance-type sensors.

Figure 16: The example connection to drive a relay
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
circumstances.
3.3.12. Digital Output with Built-in Relay
The build in relay output is Open-Drain type with no internal pull-up resistor. It means that
the user has to connect a pull-up resistor to any positive voltage to generate a correct output.
The switch capacity of the relay contact is 60W, and the max current is 2A.

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.
The example connections of UART1 with female DB-9 and UART2 with external devices are
showed as follow.
