VBrick Systems VB4000, VB6000, VB5000 manual WM Configuration

WM Configuration

Destination	• Dedicated. When Passthrough State is set as Initiator and the
	Destination is Dedicated, the VBrick appliance (whose serial port is
	the destination of this COM port) can be configured and identified
	using either an IP address or a host name.
	• Slot1 MetaData. If Meta Data is enabled on the Encoder > Video
	page, the appliance captures incoming data from the serial port and
	inserts it into the stream as metadata. In a typical application, a
	GPS receiver connected to a VBrick can insert ASCII strings
	representing map coordinates into a stream. This information is
	saved and sent as metadata with the video. To view the metadata
	strings in Windows Media player you must enable display of
	captions (Play > Captions and Subtitles). This feature is disabled
	when the appliance is in Edit mode.
	The data is inserted when it reaches the maximum number of
	characters (245 for WM) or when the Idle Timeout (see below)
	between characters is reached. Note that a four-character TEXT
	command and a trailing space are auto-inserted before any
	metadata. The Media Player recognizes the TEXT command and
	displays the metadata. This feature works for all passthrough port
	baud rates but can only accept continuous serial data at rates up to
	9600 baud; at higher rates there must be some idle time between
	metadata strings.
	• Slot2 MetaData. Same as above except the serial port data is
	inserted as metadata in the video stream from the Slot2 encoder.
Baud Rate	Rate of Passthrough port. Rate can be set to the following (Default =
	9600): 110, 300, 600, 1200, 2400, 3600, 4800, 7200, 9600, 14400,
	19200, 28800, 38400, 57600, 115200.
Stop Bits	Number of stop bits for Passthrough port (1 or 2).
Parity	None, Even, Odd.
RTS Control	Force OFF, Force ON or Automatic. If automatic, the control will be
	on when Passthrough is active.
	Note: DTR and RTS are not available for COM2. Under no conditions
	are RTS or DTR controls passed through end-to-end. All control
	handling is local.
DTR Control	Force OFF, Force ON or Automatic. If automatic, the control will be
	ON when Passthrough is active. See note above.
Operational State	Describes the current status of a Passthrough connection, including
	error conditions, if any. Refer to the Status: Network Status > Codec
	on page 94 for more information. This will display Active if in
	Passthrough mode.
Idle Time out	5–2000 milliseconds. Default = 500. The interval between characters at
	which metadata is inserted into the stream.
