In this mode, data received by an encoder is transported to the decoder, along with video
and audio, as part of the source stream. Data transport in this mode is unidirectional and is
capable of being recorded and played back by the VNM Recorder and VNR 100 devices.
Two types of data are supported:
•
Serial RS-232 data
•
Serial UDP data
Serial data transports are connected from encoder to decoder devices and are
unidirectional. As with the video and audio streams, serial data streams can use either
unicast or multicast transports. It is recommended that all stream types use the same
transport.
NOTE:
Serial RS-232 data transport also requires configuration of the corresponding
VND 250 device (see Display tab on page 59).
Serial RS-232 data transport
Serial RS-232 data that originates from an external source is transported alongside the
video stream. The external RS-232 device is connected to the RS-232 pass-through
connector on the VNE 250.
NOTE: The transport of serial RS-232 data also requires the correct configuration of
the VNM 250 serial port and the serial RS-232 port parameters (see Peripherals on
page 42).
To enable transport of serial RS-232 data, select the
Serial Enable
option.
Serial UDP data transport
UDP data that originates from an external source is transported alongside the video stream.
The external data source must set the destination IP address of the data packets to be the
same as the IP address of the encoder that is used for transport.
To enable UDP data transport, on the VNE 250 encoder, select the
UDP Enable
option and
configure the UDP port number to match the destination port number that has been set by
the external data source.
Streams — multicast enable
Select the
Multicast Enable
check box if RTP multicast source streaming is required.
Otherwise, ensure the box is deselected, to enable RTP unicast.
If
Multicast Enable
is selected, a dialog
opens asking for a multicast address (see the
figure to the right). This should be obtained from
your network administrator.
Streams — New Export Stream
The
New Export Stream
button can be used to configure streaming between devices that
are controlled by different system controllers. The VNM Enterprise Controller fully supports
this feature and Extron recommends that it be used as the system controller if this function
is required.
