Product Overview
The AT110 is a highly featured vehicle tracking device, housed in a sturdy aluminium enclosure
with external GNSS/GSM/UMTS antennas. The AT110 incorporates the very latest technology,
including the latest Cortex M3 ARM processor, ublox SARA-U2 penta-band 3G (GSM/UMTS)
communication module and ublox EVA-M8M GNSS, supporting GPS, GALILEO, GLONASS &
BeiDou navigation systems. The AT110 operates from an external voltage source in the range 5
to 50V and has an internal 950mAh back-up battery which allows operation for approx. 10 hours
in continuous mode, or 10 days in low-power mode. Basic 3 wire (power and ignition)
connections are made using a simple 3 way connector and cable assembly. More advanced
features are available by using the 36 way data connector.

Hardware Description
Dimensions
SIM installation
Note: fitting the SIM will trigger the AT110 to power up.
The AT110 must be fitted with a SIM card (micro SIM, format 3FF) to allow access to a
GSM/GPRS/UMTS network services. The SIM card is installed in a small slot in the side of the
AT110. Correct orientation of the SIM card is essential for correct operation. Push the SIM card
into the slot until the edge is flush with the AT110 case. To remove the SIM card, simply push it
again, and it will spring out. SIM PIN must be disabled.
Power requirements
The AT110 operates from a DC Voltage between 5 and 50 Volts. We recommend that a
permanent power source is used to supply the AT110. If current drain is of concern, please refer
to the power management section for options to minimise vehicle battery drain when stationary
for long periods.
Fuse Recommendations
Typical current drain is 25mA @ 13.8VDC and 14mA @ 27.6VDC, although maximum peak
current can be around 500mA for very short periods. The AT110 is supplied with a 1.0m power
cable, which is fitted with 1A fuses in the power feeds and ignition sense wires.
Back-up Battery
The AT110 operates from the external voltage source, with an internal back-up battery to allow
continuous operation for short periods without external power. The device will maintain the
battery charge level and seamlessly switch to battery power if the external voltage source fails or
fall outside of the permitted range. Note that the operating temperature range of the AT110 is
reduced when the battery option is fitted (see Specifications section). Please also note the
handling precautions for lithium polymer batteries as outlined in the AT110 Installation Guide.
Powering up your AT110
Fitting the SIM acts as the on/off switch. Your AT110 will power up as soon as the SIM is
inserted.
LED Indicators
The AT110 has 2 external status LEDs, which indicate GPS/GNSS status and GSM/UMTS network
status, as per the description below:
GPS/GNSS STATUS (GREEN):
ON CONTINUOUSLY device is powered-up and is searching for first location fix
FAST DOUBLE FLASH good fix received, typically 1Hz flash (once per second)
OFF device currently has no location fix
GSM/UMTS STATUS (BLUE):
OFF no network service
100mS ON / 2S OFF Registered on home network 2G service
DOUBLE 50mS ON / 2 SEC OFF Registered on home network 3G service
DOUBLE 100mS ON / 2 SEC OFF Registered on roaming network 2G service
50mS ON / 50mS OFF Registered on roaming network 3G service
ON CONSTANTLY device is currently transmitting data on home network
800mS ON / 200mS OFF device is currently transmitting data on roaming network
Interconnections
For basic installations, the 3 wires provided on the standard power cable are all that is
necessary, these provide power and ignition input (digital 1) using a 3 way cable which mates
with the 3 way power header on the AT110 device.

Digital Inputs
Digital inputs 1 to 4 are normally low and can be connected directly to 12/24V vehicle circuits.
Digital inputs 5 and 6 are normally high, for use in pull-down applications. Simply switch to GND
to activate these inputs.
Note: damage may be caused to the AT110 device if a voltage source is applied to digital inputs
5 and 6.
Digital Outputs
The AT110 is capable of switching 5 different loads using digital outputs 1–5, implemented with
MOSFET low-side switches. These must be used to switch the GND side of the load.
Digital outputs 1-5 are capable of handling loads of up to 30V, 0.5A maximum. The digital
output switches are protected by internal fuses, rated at 0.63A. The fuses are not userreplaceable, and are not covered by warranty, hence any replacements are chargeable. An
external fuse, rated at 0.5A will avoid internal damage to the AT110 device.
Analogue to Digital Converter (ADC) Inputs
ADC1 can be used to measure analogue voltages up to 5.0V maximum
ADC2 can be used to measure analogue voltages up to 15.0V maximum
External scaling can be used to measure higher voltages if necessary.
Integrated Accelerometer(s)
The AT110 has a built in 3 axis MEMS accelerometer that operates in the range ±2g and is used
to measure driver behaviour (acceleration and braking) during normal driving conditions.
The accelerometer also allows the AT110 to wake from sleep on movement, with configurable
thresholds. Please refer to the MEMS parameter and Power Management section for more
details.
1-wire / iButton / Temperature Probe Interface
This can be used with iButton devices for the purpose of driver ID, or with DS18B20 temperature
probes. Please refer to the appropriate application notes for more details of how to use these
features
CANBus
The AT110has integrated CANBus. Please refer to CANBus and FMS Application Notes for details
of supported protocols and features.
IMPORTANT NOTE: The CANBus pins are ESD protected to 15kV, but can only withstand
a continuous voltage of 12V maximum. These pins must not be used for any other
application to avoid damage to the device.
5-50V, 4.5V and 3.3V Outputs
These are reserved for use with external devices, all are fused at 250mA (non-resetting). The
3.3V regulated output can be used as a reference voltage for external temperature sensors and
used with the ADC1 input.

AT110-STD (Standard) Kit Contents
Our AT110 standard kit is supplied with a CB110 power / ignition cable and an AE001 combined
GSM-GPS antenna.
CB110 Power / Ignition Cable
This 3-way fused cable is used to connect a permanent voltage source (i.e. power), ground and
an ignition-switched voltage source (i.e. ignition sense) to the AT110 device. The CB001 is fitted
with our standard 4-way power / ignition connector, which mates with a matching connector on
the CB243 cable.
AE001 Combined GSM / GNSS Antenna
The standard AT110 kit includes an AE001 combo antenna, for mounting beneath the vehicle
dashboard, adhesive side down:
Alternatively, we can offer the AE003 glass-mount combo antenna, which is designed for
mounting inside the vehicle windscreen, adhesive side up:
CB113 Plug-and-Play Cable
The 30-way AT110 cable is terminated to suit the CB001 power / ignition cable (above), and also
allows easy connection of our optional accessories. Note that each accessory is fitted with a
unique connector, which matches only one of the available CB113 connectors, hence preventing
incorrect termination. The following optional accessories are available from Astra Telematics and
supported by direct connection to the CB113 cable:
• IB001 iButton driver ID probe
• CB242 OBD cable
• CB002 FMS cable
• CC001 contactless CANBus adapter
• BZ001 buzzer
• CR001 RFID/NFC card reader
• CR002 MIFARE card reader
• TP001 1-wire temperature sensor
• DB001 driver behaviour indicator
