To support a wide range of hardware applications, the AU7 is equipped with a large number of inputs and
outputs.
6 Digital Inputs (IN0, IN1, IN2, IN3, IN4 and IN5): IN0, IN1 and IN4 are positive triggers (Triggering
Voltage Range: 3.7 ~ 40V). IN0 is dedicated to ACC (Ignition). IN2, IN3, and IN5 are negative triggers
(Triggering Voltage Range 0 ~ 0.8V). These triggers can be used in the following application areas:
engine detection, car door open/close detection, and Panic Button in case of any emergency.
3 Digital Outputs (OUT1, OUT2, and OUT3): They are normally used for engine or ignition
immobilization. Please refer to our AU7 Quick Start Guide for details on how to set up relays for these
applications. These digital outputs are open collector type. When in the “ON” state, these outputs are
grounded (GND). When in the “OFF” state, it forms an open circuit. Note: Please do not connect a
positive voltage any output pin!!!
2 Analog Inputs (AN1 and AN2): Each input is usually connected to an external temperature sensor or
fuel level senor. The voltage range of AN1 is 0 ~ 40V 12-bits resolution. The voltage range of AN2 is 0 ~
5V 12-bits resolution.
1 Digital Output/Analog Input (OUT4/AN3): This port may be configured as a digital output or analog
input through the AT$IOCG command. The voltage range of AN3 is 0 ~ 40V 12-bits resolution. Refer to
the AT$IOCG command reference section for details. Note: Please do not connect a positive voltage
to an output pin!!!
1-Wire: it uses a single wire to transmit both data and power. You may use 1-Wireto connect up to
five devices, for instance, one iButtonand four temperature sensors.

SIM PIN Error
Note: In the case of SIM PIN Error, the device will check the AT$SPIN every 10 minutes and try to
access the SIM again. The PIN will be validated 3 times and if it fails the last attempt, including the first
inserting time, the SIM card will be locked. Once the SIM is locked, you need to contact your GSM
carrier for the PUK in order to unlock the SIM card using your cell phone.

When installing the AU7 onto a vehicle, please make sure that the XYZ-position of the device follows the
exact same directions as shown below. The G-Sensor operates in such a way in order to detect harsh driving
events. The forces in each axis are used to determine the status of harsh driving events. If the following
installation is not practicable, it is advised to use the GPS for detecting harsh driving as an alternative.
1. Note: When installing the device, the vehicle should be parked on a horizontal place (not tilted).
Then, the device should be installed parallel to the vehicle body and fixed with a mounting
bracket or double-sided adhesive to ensure that the G-Sensor works properly.
2. Note: It is strongly recommended that an automobile technician is required to be involved for the
above installation.

In this section, we are going to demonstrate how to do firmware upgrade on the AU7 via the serial connection.
Before doing the upgrade, connect the serial cable between the JST XHP-4 output connector and the serial
communication port (e.g. COM1 or COM2) on your PC. You may use a USB to serial port converter in case
your PC doesn’t have any COM port.

Command Description
The 16-pin female power I/O cable has a dark green wire which can be used to identify this unique
configurable I/O port. This port can be configured or queried through the AT$IOCG command. It is
recommended to disconnect the I/O connection prior to changing the I/O characteristic in order to avoid any
damage to the I/O port.
