COM Port Setup sub-tab provides insertion/extraction
controls, and comm rules and status displays where serial
comm is used for insertion and/or extraction.
Note:
•
COM 1 and COM 2 are independently available for ANC Tx/Rx and have identical controls. Therefore, only the COM
1 controls are described here.
•
Controls provided here allow highly detailed setup of serial communications. Control settings must be carefully
considered and set appropriately to correspond to both sending and receiving systems. Incorrectly set controls may
result in loss of ANC serial comm.
•
COM 1 and COM 2 are multi-function interfaces and must be set for ANC Data Extractor for port(s) is to be used here.
Set the port function as described in COM Routing in COMM Ports Setup Controls (p. 3-66).
• Rx/Tx Status Display
Shows either no data received/sent, or where transfer is present shows
data rate (in kbit/sec).
• Insertion Mode Control
Where data is being inserted (received), sets the insertion as follows:
• Insert Any Data Received: Insert all received data with no regard
for packet size.
• Fixed Length Packet: Sets receive to wait and accumulate
n-number of packet bytes (as set using Insertion Fixed Packet
Size control) before inserting data.
• Break-Defined Packet: Device receiver looks for character-defined
break from source being received to define breaks.
• Insertion Flow Control
Allows communication between receive and sending source to regulate
data receive as follows:
• No Flow Control: Data is received without buffering or checking to
see if data is being received faster than it can be inserted.
• XON / XOFF: The device UART Tx will tell the sending source
whether it can or cannot accept data at current bit rate.
• Hold Break: Device, if close to not being able to accept new data,
tells the sending source to hold, and releases this hold when the
device is again able to accept new data.
• Insertion Sync Byte Control
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.
• Extraction Mode Control
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.
