SKU: SU-1200

The SU-1200 takes vehicle tracking to the next level!

Simply Unified has used the latest 4G Cat-M1/NBIoT modem, the SU-1200 tracking device has several inputs and outputs providing a quality solution for virtually any application.

Both our GPS and Mobile antennas are internal, therefore reducing the risk of tamper—an internal back-up battery to provide alerts and tracking operations even when the external powered lost.

Optional Satellite Connectivity

Add the Iridium Edge device to your SU-1200 to provide Global Coverage (additional fees and charges apply)

Full Description


Snap-Clip ABS Plastic Housing
Made of sturdy UV resistant plastic the housing clips together for easy assembly, and has 2 convenient mounting tabs.

Dimensions: 125mm x 65mm x 30mm
Weight: 250 grams

Operating Temperature

On external power
-20°C to +60°C

Below 0°C the standard internal back-up battery’s ability to deliver sufficient power to operate the cellular modem is reduced. Below 0°C and above +45°C the internal back-up battery will not be charged as a safety precaution due to dangers associated with charging batteries at extreme temperatures.


24 pin connector, A harness is supplied as standard with the SU-1200

Input Voltage:

8V to 45V DC (max)

Operating Current:

Up to 200mA peak (excludes switched power outputs)

Sleep Current:


Internal Back-Up Battery

1100mAh Li-Po Internal Back up battery.

Allows for an external power removed alert, and the device to continue tracking for some time should there be a power cut.

Self-resetting fuse

The SU-1200 passes stringent automotive power “load dump” tests to ensure that it will continue to operate in the harshest electrical systems. A built-in self-resetting fuse makes installation easy and safe.

Flash Memory

Normally data is sent to the server immediately, but if the device is out of range, there is space to ensure no data is lost – for many weeks of driving!

3-axis accelerometer

Allows the device to detect harsh driving events, and to go to ‘sleep’ when not moving, resulting in extremely low standby current

Bluetooth 5.0

The SU-1200 is equipped with a Bluetooth v5 module, enabling it to communicate with Bluetooth tags and sensors. Such tags can be placed on low-value assets to provide their position when in range of the SU-1200.

Sensors, e.g. temperature/tyre pressure can relay information to the SU-1200, which will upload the data to the server. Contact DM for sensor support

Sim Size:

Micro (3FF) size cellular SIM card

4G Modem:

uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands. These new low-power networks are specifically designed for IoT applications, providing great battery life

Supported LTE bands:

1*, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26*, 28 (*roaming bands)

Optional Satelite Connectivity:

Iridium Edge (additional fees and charges apply)

GPS and Cellular Antenna

Internal GPS and cellular antennas tuned by RF laboratories for optimal performance. Having the antennas inside the housing makes for very simple and quick installation

Concurrent GPS and GLONASS Tracking

72 channel high sensitivity receiver

-169dBM industry-leading tracking performance

Low noise GPS Amplifier

GPS signals get boosted by a special low-noise amplifier (LNA). This allows operation where other units will fail to receive the GPS signal.

1 x Ignition Digital Input
0-48V DC, 5V on/off threshold

6 x Digital Inputs
6 x Digital Inputs with configurable pull-up/pull-down
0-48V DC input range

2 x Digital Outputs
2 x Switched Ground Digital Outputs, easily wired up to switch external lights, relays, buzzers etc. Can be used to immobilise a vehicle. 500mA max.

1 x Analogue Input
1 x 0-30V analogue input, with auto-ranging

Internal Buzzer

Audible alert without requiring the installation of an external buzzer. Can be used for speeding alerts, harsh driving alerts, reminders to swipe RFID tags, error conditions, input feedback and other events.

2 x Switched Power Out

The SU-1200 can provide power to external peripherals allowing for easy installation and doing away with the need for additional external power supplies.

Outputs are either 5V (external power connected)
or Vbatt (no external power)

Maximum current: 400mA

Driver Identification

Driver ID via RFID reader or iButton

The SU-1200 gets updated from the server with lists of Drivers that are allowed to drive the vehicle.

Supported Driver ID interfaces:

RS232, Wiegand, TTL, iButton

3rd Party readers which output one of the above formats can be integrated into the SU-1200 FW to enable current site cards/passes to be used.

Can be used to connect and Iridium Edge Module for out of cellular coverage.

Allows for support of other Driver ID card readers (requires integration work)

The diagnostic LED makes it easy to see if the device is operating correctly.

Flexible Logging Parameters

The SU-1200 trip logging is flexible and can be configured to log based on a variety of parameters including:

Elapsed time, Distance travelled, Change in a heading, Change in speed, On Stationary, Accelerometer events (harsh driving)

Accident and Rollover Detection

The SU-1200 uses the built-in accelerometer to detect high G impacts such as accidents and rollovers and reports these events to the server for emergency alerting.

Harsh Driving

The SU-1200 automatically calibrates its built-in three-axis accelerometer and uses this to detect harsh driving events:

  • Excessive acceleration
  • Harsh braking

Cornering at speed

These events are logged in the SU-1200 along with additional event statistics that allow back-end server platforms to perform sophisticated driver profiling and scoring.

Accident Data

The SU-1200 keeps a second-by-second “black box” recording of valuable GPS and accelerometer data for a two-hour window. This data can be automatically uploaded to the server when an accident is detected, or it can be requested manually.


The SU-1200 can hold hundreds of geo-fences that can be downloaded to it from the server. The SU-1200 can use this geo-fence information to:

Implement arrival and departure alerts

Implement speeding zones with audible warning alerts

Implement “No-go” and “Keep-out” areas

Automatically control outputs, e.g. to switch on warning lights when inside a special area.

Ignition Detection


The SU-1200 can determine a trip has started based upon:

Wired Ignition input (voltage on/off)

Emulated Ignition (GPS movement)

Run Detect (Voltage Increases)

Bluetooth Firmware

The SU-1200 continuously scans for Bluetooth devices. DM products include the Guppy Bluetooth and SensorNode Bluetooth.


The SU-1200 intelligently maintains a list of devices in range and reports the list to the server on the following conditions:

Tag found (comes into range)

Tag lost (goes out of range)

Periodic list update

Accident Data

The SU-5100 keeps a second-by-second “BlackBox” recording of valuable GPS and accelerometer data for a two-hour window. This data can be automatically uploaded to the server when an accident is detected, or it can be requested manually.

Driver Identification

The SU-1200 supports several ways to identify a driver:

RFID reader and a card or keyfob

Five-digit keypad to enter a PIN code

Console with built-in RFID reader

iButton 1-wire reader

Driver Identification

The SU-1200 can be updated from the server with lists of Drivers that are allowed to drive the vehicle that it is installed in. When a driver or operator registers on the SU-1200 it will check the Driver List to see if that person is authorised to drive the vehicle. The list also includes information about the driver such as whether they can perform supervisor functions.
