LCD Alarm or Warning

Meaning / Possible Cause

Message

 

 

 

 

 

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.

 

 

 

 

No PAT

No Program Allocation Table detected in input carrier (or terrestrial interface).

 

Check that legal ISO transport is available from uplink mux. Often, this

 

indication may appear when the connection between the uplink transport mux

 

and the DVB modulator is lost.

 

 

 

No PCR

No Program Clock Reference found, either in video or stand-alone PID. Check

 

uplink mux or that program's encoder.

 

 

No PMT

No Program Map Table found for a program listed in PAT. This could be a fault

 

in the uplink mux.

 

 

 

 

No RF Signal

No carrier lock with low RF signal power indication. There may be a

 

disconnected RF signal. Check connection and check that LNB has DC power.

 

 

No SDT Entry

No Service Descriptor Table, or the table is corrupt or missing proper entries.

 

Uplink mux may not support this DVB feature or may have fault.

 

 

No Valid Software

No valid application software available in either the primary or backup flash

 

positions. Unit will need service.

 

 

 

No VBI Data FN LM

VBI data not found in video user data or PID for Field N line M If any is

(N=field number;

expected, contact network TOC.

M=line number)

 

 

 

 

 

PAT Disappeared

Formerly valid Program Allocation Table ceases to be received or becomes

 

corrupt. See "No PAT" indication.

 

 

PAT Version Changed

Version number in Program Allocation Table has changed but no change to

 

program lineup.

 

 

 

 

PCR Disappeared

Formerly valid Program Clock Reference ceases to be received or becomes

 

corrupt. See "No PCR" indication.

 

 

PCR Jitter

Excessive jitter in Program Clock Reference values. This may degrade timing

 

of output video signals. Check uplink encoder for that program.
