Special Messages give commands to the terminal. They may be
called up using either a value trigger (the message number) or a bit
trigger, just like other messages. See Page 4–5 for a list of Special
Messages.
The Special Messages dialog is used only when:
•
one or more Special Messages need to be defined as a bit trigger.
•
the Special Messages Set Time/Date or Set Brightness will be
used, and needs to have its read tags assigned.
•
the Special Messages Get Time/Date or Test Battery will be used,
and needs to have its write tags assigned.
To assign a bit trigger to a Special Message
1. Select Special Messages on the Application menu to bring up the
Special Messages dialog:
2. Select the Bit Trigger Enable box for the special message.
3. Use the Bit Number spin control to assign an address to the bit
trigger.
4. When all special messages are edited, select OK to return to the
Message Editor Table View.
Important: Bit triggers cannot be used when the terminal is
controlled by an ASCII Triggering Device.
