COMM Ports Setup Controls
Provides controls for setting up the two COMM (serial)
ports for LTC or ANC functions, and setting comm
protocol for each port.
Note:
This tab has identical independent controls for COM 1 and COM 2. Therefore, only the COM 1 controls are described
here.
• COM Mode (Protocol)
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.
• COM Port Tx Routing Function
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.
• 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: Card receiver looks for character-defined
break from source being received to define breaks.
• Insertion Flow Control
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 card UART Tx will tell the sending source
whether it can or cannot accept data at current bit rate.
• Hold Break: Card, if close to not being able to accept new data,
tells the sending source to hold, and releases this hold when the
card is again able to accept new data.
