TTL Port CONTROL WITH BrightAuthor

How to setup the TTL Port (initial state)

1. Select 'File'' (Main panel)

    2. Select 'Presentation Properties'

        3.Select 'Interactive'

4. Select 'Edit'

    5. Select Preferences

          6. Select Interactive.

Set the settings for the TTL Port as shown:

Note: Some HMS Boards run at 19,200 baud, some run at 38,400 baud.  Refer to the specification sheet for the correct settings for a specific board.

How to Send TTL data during 'Play':

During 'play' if you want to send TTL bytes (like when a video or slide plays), then select the image or the event (like timer), right click and select 'Edit'.  
Select 'Add Command' (see picture below) and add the command 'Serial Send-Bytes, comma separated'. Set the two bytes that you want to send to Port1 and Port2 on the HMS board.

Note: On the main BrightAuthor 'pain', with 'Interactive' previously selected you will see the 'event' 'Serial Input'.  Use this event to respond to a byte from the HMS board.  Do not try to set the port values there (baud and so on), as the parameters that you set won't be applied.

Note: The term 'On' means 'Logic 1' or 'High', and the term 'Off' means 'Logic 0' (zero) or 'Low'.
