4.7.2 Data A - RS232 Menu
Table 4.19 shows the options for the Data A – RS232 Menu options.
NOTE…
If RS232 data is turned on it is not possible to turn Ethernet data on.
Table 4.19: Data A - RS232 Menu Options
Selected Item Options Description
Off
On(Wegener) If On (Wegener) is selected, the stream is identified in the PMT as a
component of type 0xC1 with no descriptors.
Wegener ASYNC data are transmitted as private stream 2 type data. This
stream conforms to ISO13818. The adaptation field is used to add stuffing
bytes if needed to complete a TS packet. Stuffing bytes are set to a value of
0xFF. Payload data bytes follow the packet length field and do not include a
CRC field.
On(Motorola) If On (Motorola) is selected, the stream is identified in the PMT as a
component of type 0xC0 with no descriptors. The RS232 data is encapsulated
directly into the full 184 payload bytes of the transport packets (i.e. no PES
layer).
The RS-232 data-stream is expected to contain complete DCIIText packets.
These packets must be preceded by the sequence (0x7F, 0xFE, 0x7F, 0Xfe)
followed by 2-bytes which contain the length of the DCIIText packet. Once this
sequence is detected, the option Locked Motorola indicates Yes.
On(DVB) This is the format specified by DVB
On(Tandberg) This is a proprietary format
Encoding:
Switches the RS-232
asynchronous data channel On or
Off.
If Ethernet data is turned on it is not possible to turn RS232 data on.
1200 1200 Baud rate.
2400 2400 Baud rate.
4800 4800 Baud rate.
9600 9600 Baud rate.
19200 19200 Baud rate.
Baud Rate:
Sets the baud rate of the RS-232
asynchronous data channel.
38400 38400 Baud rate.
RS232 PID:
Enter or update data PIDs.
PIDs 32 to 8191 are
available for use. To be DVB compliant, PIDs below 32 are reserved. In the event of a clash, one
of the PIDs will be changed by the Encoder’s internal checking algorithm.
Component Tag:
Defines the optional component tag
to be assigned to this data stream.
Send immediately This option is only available in Tandberg mode.
Whenever data is available at the RS232 port it is sent in the output transport
stream. This can result in wasted bandwidth due to low packet occupancy.
Also results in a higher packet rate which may cause some receivers to
overflow.
Buffer Data:
Wait 1 Second Data is buffered until enough has arrived to fill a transport packet or 1 second
elapses, whichever occurs first.
