Output Channel1
The Output Channel1 does the following tasks:
• Sets the length in the module's output tag to the number of characters to
be sent.
• Copies data from the STRING (OutData1) to the module's output tag.
• If CN0 = 1, manually triggers the Tx Transaction ID in the module's
output tag. This tells it that you have some data for it to send.
