The Enable all button quickly enables all messages. The Disable all button disables all
messages.
On RT4000 systems the default set of CAN messages may overload the CAN bus
(depending on how many slip points are used and whether local co-ordinates are
configured). It may be necessary to reduce the number of messages that are output on an
RT4000 system.
The Status tab (Figure 31) 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 Postfix boxes can be used to quickly add alpha-numeric strings to the
beginning or end of all status message names. By clearing the prefix or postfix, and then
clicking the Apply button, the original name will be restored.
The Identifier offset box allows users to quickly apply a blanket offset to identifiers.
This is useful when IDs conflict with other equipment. 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 a “h”. To remove the offset,
type 0 in the identifier offset box and click Apply.
The Select all button quickly enables all status messages. The Clear all button disables
all status messages. Messages shown in grey are not included in the CAN DBC file.
