Wegener Communications 4600 manual Changes have been made on uplink transport mux

			Unity 4600 User’s Manual
	LCD Alarm or Warning		Meaning / Possible Cause
	Message
	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
	(N=audio port number)		wildcard-assigned 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".
	No Def for mapping		ASI transport output bears no program content because an
			Output Definition Table has not been loaded from the
			network. Contact network TOC.
	No DHCP server found		IRD is required to get IP settings from DHCP server but none
			are detected on the LAN.
	No genlock sync		IRD supports and has genlock option installed and enabled,
			but no video reference sync is detected.
	No ID Tag found		No carrier ID tags in COMPEL→ stream. Set IRD not to
			expect ID tags or check uplink UMX5010.
	No KMS stream		No KMS stream detected since transport stream acquisition.
			Unit will not be authorized if not connected to the KMS
			stream. Check that KMS PID is set correctly in unit. If okay,
			check the uplink.
	No LAN detected		No Ethernet LAN connection. Check LEDs on rear and check
			other devices on the LAN.
