Page 3: Introduction
Up to four different variables can be chosen to be displayed, one at a time. The display receives data and power via a CAN bus running at up to 1 Mbit/second, with the factory default at 500kbit/sec. Alteration of either the bit... -
Page 4: Can Network Topology
CAN BUS CAN NETWORK TOPOLOGY The CAN bus is structured as a linear network, with short stubs branching from 'T' connectors on the main bus backbone to each device. The CAN bus data lines must be terminated at each end of the main bus with 120 ohm resistors between the CAN-H and CAN-L signals. -

1 Mbit/second, and comes programmed from the factory with a CAN base address that will allow it to work without problems with other Tritium devices. Currently, modifying the data rate or CAN base address requires reprogramming the microcontroller, although hardware support is provided to allow updates over the CAN bus in the future. -
Page 6: Mounting
The LCD display is based around a Texas Instruments (TI) MSP430 16-bit embedded low-power microcontroller, operating from a clock derived from a multiplied 32.768kHz watch crystal as default. CAN bus support is provided via a Microchip MCP2515 CAN controller and TI SN65HVD234 CAN transceiver. The display is not isolated from the CAN network. -
