The user can either choose a fixed test message, define an entire message
content, or define data sequences. The fixed simulation message is
selected with the SIMULATE TEST_MESSAGE command in the
advanced level.
There is a predefined fixed test message for each message type. If a fixed
test message is selected, one of the messages in the following section is
transmitted depending on the selected message type. The data values in
the messages are as shown in the following section. The frames of the
messages are not fixed but depend on the current configuration.
When changing the predefined, fixed test message type, first turn the
simulation off by giving the SIMULATE OFF command in the
advanced level and then change the message type (with the SET
MESSAGE TYPE number command). Turn the simulation on again by
giving the SIMULATE TEST_MESSAGE command.
When changing the user defined data sequences, first turn the simulation
off by giving the SIMULATE OFF command on the advanced level and
then change the message type (with the SET MESSAGE TYPE number
command). Turn the sequence simulation on again by giving the
SIMULATE SEQUENCE command.
Message 3 (Status message) has no simulation message. Message 3
(Status message), Message 5 (FD12 MSG2), and Message 6 (FD12
MSG7) are not supported by simulation sequences.
