COMM Ports Setup Controls

•
Note:
COM 1 and COM 2 sub-tabs provide independent controls for COM1 and COM2. 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. 3-59).
• COM Mode (Protocol)
• COM Port Tx Routing Function
• Rx/Tx Status Display
• Insertion Mode Control
• Insertion Flow Control

BBG-1022-2FS Function Menu List and Descriptions
Provides controls for setting up the two COMM (serial)
ports for LTC or ANC functions, and setting comm
protocol for each port.
Selects serial comm protocol for the respective port as RS-232 or
RS-485.
Note: Protocol choices should consider the payload to be carried.
Typically, LTC is sent or received using only RS-485 serial
protocol.
Selects port function for the respective port as LTC Encoder input or
output, or ANC Data Extractor / Audio (SMPTE 337) non-PCM input
or output.
Shows either no data received/sent, or where transfer is present shows
data rate (in kbit/sec).
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.
Allows communication between device 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.
