Unity 4600 User’s Manual
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
(N=audio port number)
No "free" otherwise-unassigned audio can be allocated to
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.
