Each message can be enabled/disabled by clicking in the appropriate cell and selecting
from the dropdown menu. The message Identifier is also changed by clicking in the cell.
The identifier number should be defined in either hexadecimal or decimal format. Decimal
values can be entered as normal. Hexadecimal values should have a letter “h” appended.
The Data rate
can be set using the dropdown list that appears after clicking in each data
rate cell. When a message’s data rate changes or it is enabled or disabled, the caption at the
bottom of the window displaying messages per second
updates to reflect the new settings.
The Enabled checkbox quickly enables and disables all messages.
The
Status
tab lists all status messages, which are sent one after another in a repeating
loop. Although 80 messages are shown in the list, 100 are actually used internally. If the
data rate is set to 100 Hz, a status message will be sent every 10 ms. Some messages are
transmitted more frequently than others because they appear in the list more than once. At
a data rate of 100 Hz, each message in the Status tab will be transmitted on the CAN bus
once per second.
The Prefix and Suffix boxes can be used to quickly add alpha-numeric strings to the
beginning and end of all message names, while the Identifier offset box allows users to
quickly apply an offset to all CAN IDs. These tools are useful when IDs conflict with other
equipment and changes need to be made to many channels.
Positive and negative integer values can be entered into the Identifier offset box in both
decimal and hexadecimal formats. Data entered in hexadecimal format should end with an “h”.
To remove the offset, type 0 in the identifier offset box.
The Enabled checkbox quickly enables and disables all status messages.
The Message name, Signal name and Units can be edited in the table. Changes made using
NAVconfig are independent of the DBC file, and will not affect it or be saved.
