BBG-1022-2FS Function Menu List and Descriptions
(continued)
Allows use of a sync byte from device receiver back to sending source to
synchronize communication between device receive and sending source
as follows:
• Disabled: No special synchronization.
• Field Number at SOF: The device sends a single byte telling
sending source when start of field 1 or field 2 is occurring.
• Ack on Insertion: Device sends a single byte back to sending
source when data has been inserted.
Where data is being extracted from input video, sets the data to be sent
as follows:
• Payload Only: Sends payload only (for example, for closed
captioning this would be only the ASCII character string
representing the CC content).
• Full Anc Data Packet: Sends the entire packet, including payload,
DID, SDID, and any handling or marking characters.
Allows communication between device transmit and receiving
destinations to regulate data receive as follows:
• No Flow Control: Data is transmitted without buffering or checking
to see if data is being transmitted faster than it can be received.
• XON / XOFF: The device UART Rx will acknowledge from the
receiving system whether it can or cannot accept data at current bit
rate.
• Hold Break: Device, if receiving notification from the receiving
system that it is close to not being able to accept new data, tells the
device to hold. Device releases this hold when the receiving system
removes the break command, indicating destination is now ready
again to accept new data.
For both Rx and Tx, sets UART for bit rate and parity as follows:
• Bit Rate: Sets Tx/Rx bit rate from 1 of 5 speeds ranging from 9600
to 230400 Baud.
• Parity: Sets device Rx to expect odd or even parity from incoming
data, and sets device Tx to generate a parity bit to satisfy selected
parity. Where parity is set, incoming data not conforming to parity
selection is rejected.
