Selected Option
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 optionj Locked Motorola
indicates Yes.
On(DVB)
This is the format specified by DVB
On(Tandberg)
This is a proprietary format
NOTE…
If Ethernet data is turned on it shall not be possible to turn RS232 data on.
Baud Rate Option
This option enables the baud rate of the RS-232 asynchronous data
channel to be set.

RS232 PID Option
This option is used for entering or updating data PIDs. To be DVB
compliant, PIDs below 32 are reserved. Therefore PIDs 32 to 8191 are
available for use. In the event of a clash, one of the PIDs will be changed
by the Encoder’s internal checking algorithm.
Component Tag Option
This item defines the optional component tag to be assigned to this data
stream.
Buffer Data Option
Send immediately: Whenever data is available at the RS232 port it is sent
in the output transport stream.
