Output Channel0
The Output Channel0 does the following tasks:
• Sets the length in the module's output tag to the number of characters to
be sent.
• Copies the data from the STRING (OutData0) to the module's output
tag.
• If CN0 = 0, manually triggers the Tx Transaction ID in the 1769-ASCII
Module's output tag. This tells it that you have some data for it to send.
