Trombetta Gyro-Compensated Inclinometer

Description

The gyro-compensated inclinometer, referred to as ‘the device’, transmit its relative angle over a CAN network. This
device offers advantages over standard MEMS inclinometers by helping to filter out sources of inaccuracy, such as
vibration and shock of an operating vehicle.

General Operation

At power up, the device will detect the baud rate of the CAN network. It does this by cycling through the available
baud rates until it sees communication on the bus. Note: the device requires two active fixed baud rate devices
communicating on the bus to detect the baud rate.

Once the baud rate is detected, the device will begin transmitting the angle of each of the sensors. These messages
are transmitted continuously on the CAN bus. Each sensor transmits from its own customizable source addresses.
Sensor 1 is assigned address 0xE2 by default. Sensor 2 is assigned address 0xE3 by default. The average reading
between sensors 1 and 2, called the compensated sensor data, is transmitted under address 0xEA by default.
When the device has power, the green ‘PWR’ LED will turn on.

When the device is communicating on the CAN bus, the red ‘CAN’ LED will flash. If the unit has lost communication
to the CAN bus, the red indicator LED will stay on.
Operational Variants

There are different variants of this device. These device’s vary on which mode they can operate in. The available
modes are:

• Dual-Axis Mode
• Single-Axis Mode
