CANvu 350

The CANvu CAN bus display range now includes a new fully sunlight viewable 3.8" color display. The CANvu is the next generation of compact, highly flexible, rugged CAN bus displays from Veethree.

MotoHawk Library for CANvu

Customers have requested a display that is more functional than the small, inexpensive MiniView gauges, while not requiring as steep a learning curve or software investment as developing a full custom application for the CANtrak or CANvu displays. The CCDM tool for the CANtrak displays fits this bill, but experience with New Eagle and its clients using it has suggested that it is simply too buggy and finicky to be a workable solution. A number of customers currently have experience with the MiniView gauges which are configured through a MotoHawk library. Therefore, it was decided to create a MotoHawk library and corresponding display-side software for the CANvu displays from Veethree Instruments.

The MotoHawk Library comprises several MotoHawk blocks that allow a user to easily configure the following 5 screens on a CANvu display:

One single gauge screen (mapped to Button 1)
Two quad gauge screens (mapped to Button 2 and 3)
One Text screen (faults) (mapped to Button 4)
One strip chart screen (mapped to Button 5)

Here are some screenshots to demonstrate the MotoHawk CANvu Library Blocks and Screens

CANvu VEM 400N

[[Image:CANvu400.JPG|right] CANvu MH Library CANvu 400N is a next generation CAN bus display. It is highly sealed and provides tough, flexible instruments ready to face the challenges of harsh environments. CANvu 400N has a brightness rating of 400 NIT for indirect sunlight. The Veethree Engine Monitor (VEM) software displays transmitted J1939 engine and transmission data and active alarms where supported. The VEM application software runs on the CANvu robust industrial graphical displays. The VEM offers user selectable icon based display layouts and includes a comprehensive multi language text based fault warning and acknowledgement system.

Features include:

Color Display - Indirect Sunlight Readable
J1929/Tier 4, 3.8 inch display for indirect sunlight
QVGA graphical high resolution 320 x 240 color display
Max brightness of 400 NIT on the unit
Fully sealed to IP67 using molded in 12 way Deutsch connector
4 serial comm ports: CAN bus, RS232, USB and RS485
Screens can be “locked” to prevent changes
Optional Service Interval Timer Alarm
Data is available in several formats and measurement units

CANvu J1939 Engine Monitor

The Veethree Engine Monitor (VEM) is a J1939-compatible engine / transmission display.

The VEM is a user-configurable application software that creates graphical instrument clusters to display parameters and alarms. Providing users with a timesaving solution for introducing equipment incorporating higher degrees of electronic display and control.

There is an omission in the datasheet in section 5.4 about choosing which data to display. The instructions to do so are listed below.

The left little square shows what can be displayed on the quad screen layout.
The right little square shows what can be displayed on the single gauge screen.
If the little square is red, then that item is not available.
If it is black then that item will not be shown, but can be edited and changed to white which means it will be shown.
The text if it is red means, that is the item you are editing with the button keys on the bottom.
CAN signals must be present to be shown or edited.
