5.6 Miscellaneous Option Cards
The Edit window allows the configuration of the following settings:
Signature Control : Signature Control controls when messages will be broadcast in
response to events on the Event Input (J2) port when events are enabled and the card is in
"broadcast" mode. (Events are still queued even if they are not broadcast, and are trans-
mitted once the signature control conditions permit.) For more information on Signature Con-
trol, see "Signature Control" on page 201.
Format : Selects the format of the message to be outputted. Refer to "ASCII Time Code
Data Formats" on page 464 for a description of all of the available formats.
The Event Broadcast card only supports two formats (Event Broadcast Format 0 and Event
Broadcast Format 1), and only supports the output of one message per event. If format is
set to "None", no messages will be queued in the Message Buffer.

selections are as follows:

Broadcast —Event Messages are automatically broadcast when they are created by
an event. If a new event happens while an older message is being broadcast, the

has finished, the next message out of the queue will be broadcast.
Request —Event Messages are only broadcast in response to a Request Character.
New messages will be queued in a "First-in, First-out" manner.
