Accelerometer
The Micronet SmartHub Underdash OBC provides an Accelerometer, Compass and Gyroscope module.
The accelerometer is an electromechanical device used to measure acceleration forces. Such forces may
be static like the continuous force of gravity or, as is the case with many mobile devices, dynamic to
sense movement or vibrations.
Acceleration is the measurement of the change in velocity or speed divided by time. For example, a car
accelerating from a standstill to 60 mph in six seconds is determined to have an acceleration of 10 mph
per second (60 divided by 6).
Wiggle Sensor
The Micronet SmartHub Underdash OBC provides automatic Power-up trigger to turn on the device when
sensing movement of the vehicle or closing the vehicle door.
SAE J1939 CANBus
The SmartHub Underdash OBC provides two SAE J1939 CANBus ports that enable the connection of a
variety of vehicle peripherals, such as the vehicle's computer, vehicle's sensors and so on.
Single Wire CANBus
The Micronet SmartHub Underdash provides a single wire CANBus port through its main cable.
SAE J1708
The SmartHub Underdash OBC provides SAE J1708 port. The SAE J1708 is a standard used for serial
communications between ECUs on a heavy-duty vehicle and between a computer and the vehicle. With
respect to Open System Interconnection model (OSI), J1708 defines the physical layer.

Overview
The SmartHub Underdash power comes directly from the vehicle's 12V/24V DC battery and provides
intelligent power management options that reduce drain on the vehicle’s battery.
Super Capacitors
The SmartHub Underdash has a super capacitor inside to:
Provide power backup if the main power source is disconnected.
Provide power backup during an ignition event (vehicle start up).
The SmartHub Underdash automatically manages power and super capacitor charging. The
operation time of the SmartHub Underdash while powered by the internal super capacitor is
dependent on the peripherals and applications being used. Nevertheless, the estimated time of
continued operation for standard applications is ~20 seconds.
The super capacitor will take approximately 20 minutes to charge when the device is first powered
on by the battery. After 20 minutes, the super capacitor should be fully charged and will provide up
to 20 seconds of backup power to the device.
When power is initially connected to the SmartHub Underdash, charging on the super capacitor
starts. The SmartHub Underdash may not power up immediate as the systems is waiting for the
super capacitor to reach a predetermined value. This initial charging could take up to 1min before
the power LED turns on. Power may be connected to the SmartHub Underdash at any time.

Electrical Installation Procedure
1. Prepare the wiring for power and all other required peripherals in the vehicle, for connection to the
SmartHub Underdash main harness cable.
2. Connect the main harness cable 20 pins and 50 pins Molex connectors to the SmartHub Underdash
connectors inside the cable compartment.
3. The power signals from the main harness cable should be connect to the vehicle's power line
protected by a 10A fuse. An inline 3A "Slow Blow" fuse (with fuse holder for HHC/HHD blade-type
fuses) should be add to the main power cable.
4. To power on the SmartHub Underdash turn on the ignition switch or to hit the SmartHub Underdash, the
wiggle sensor will turn on the device.

FCC Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions (1)this device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
