4.8.13 ISO Trip Header
DataLINE provides the user with an interface to view/
modify current settings of the ISO trip header through
the ISO Trip Header screen.
The ISO Trip Header screen is displayed when the
user clicks on the “ISO Trip Header” button in the “Trip
Functions” Group Box on the System Tools screen.
F9 function - Provides the user with a shortcut for man-
ually triggering the refresh operation. Before sending
modified parameter values, the user must ensure that a
successful connection is established with the controller.
If the connection is established with the DataCORDER,
the current contents of the ISO Trip Header from the
DataCORDER will be displayed in each field. If the
connection is not established with the DataCORDER,
all fields on the screen will be displayed as “Xs.” If at
any time during the display of the ISO Trip Header
screen the connection is not established or is lost, the
user is alerted to the status of the connection.
After modifying the values and ensuring a successful
connection has been made with the DataCORDER,
click on the “Send” button to send the modified param-
eter values.
The maximum allowed length of the ISO Trip Header is
128 characters. If the user tries to refresh the screen or
close the utility without sending the changes made on
the screen to the DataCORDER, the user is alerted
with a message.
