Wegener Communications 4600 manual Invalid VBI Data Fmt, Invalid Video Format, IP Address Conflict

	UNITY 4600 USER’S MANUAL
	Table 4.1: Alarm and Warning Descriptions
LCD Alarm or Warning	Meaning / Possible Cause
Message
Invalid COMPEL Hdr	Invalid COMPEL header detected in incoming COMPEL messages. This will
	cause the unit to immediately attempt automatic recovery to a backup preset.
	The IRD is not set up for connection to this COMPEL system.
Invalid VBI Data Fmt	VBI data found in PID or video user data in unrecognized or unsupported format
	(protocol).
Invalid Video Format	Video format in requested program is not supported.
IP Address Conflict	LAN detected but cannot use because of IP address conflict.
KMS Stream Lost	KMS stream lost after initially detected in this transport stream. There could be
	an uplink problem. See also "No KMS stream" indication.
Lost COMPEL PID	Data traffic at designated packet ID (PID) for COMPEL has been lost for more
	than two minutes. See "No COMPEL" indication.
Lost VBI Data FN LM	VBI data for field N, line M has disappeared. If any is expected, contact network
(N=field number;	TOC.
M=line number)
Low RF Level	There is carrier lock, but the RF signal level is too low.
New PAT with Changes	The version number on the Program Allocation table has changed and a new
	program lineup has been submitted. Changes have been made on uplink
	transport mux.
New PMT with Changes	The version number on one or more of the Program Map Tables has changed
	with a new PID lineup submitted. Changes have been made on uplink transport
	mux.
No ASI Stream	Corrupt or missing input ASI stream. Only applicable if ASI input is available and
	selected. Check connection and source.
No Audio for Port N	No "free" otherwise-unassigned audio can be allocated to wildcard-assigned
(N=audio port number)	port N. There may be fewer audio PES streams than installed audio ports. If so,
	explicitly assign a desired language descriptor to this audio port.
No Carrier Lock	Carrier lock cannot (or has not) been acquired and maintained. Check that
	requested settings are correct. Check RF level indication and RF connection.
	For new installations, check antenna pointing and polarization.
No COMPEL	®
	Data traffic is detected at designated packet ID (PID) for COMPEL . However,
	no valid COMPEL messages have been detected during the last two minutes.
	There may be no connection to the network. If required to maintain a
	connection, the unit will eventually attempt an automatic recovery to a backup
	preset. To debug, check that the COMPEL system at the uplink is functional and
	that the data connection to inserter (such as UMX5010) is good. Also check for
	fault indications or functional problems at UMX5010.
No COMPEL PID	No traffic detected at designated packet ID (PID) for COMPEL, so no
	connection is made to the network. The COMPEL PID setting in the unit may be
	incorrect. Also see "No COMPEL indication".
