The single Evertz encoder is on the receive side of the VBI Bridge. Starting with 8084 and 8084AD
firmware dated R010621, the receiving encoder can perform other captioning functions as well as re-
encode data as a VBI Bridge. This allows the user to insert new XDS, V-Chip, WebTV or other data,
and manipulate the re-insertion of the pre-existing data on a stream-by-stream basis.
The serial port on the Hubcap is fixed at 9600 baud, 8-bits data, 1 stop bit, no parity. The user must
ensure that the caption encoder is also configured to 9600 baud. Other serial port settings in the Evertz
encoder are changed automatically when the user selects CC Receive operation.
