frequency (for domestic C-band satellites, this is 5150 minus the downlink frequency in MHz). To rule out (2), try connecting the RF cable to another RF port and select that port (or use RF Switch Bypass to force that other port). To rule out (3), try using another IRD.

2.If the first alarm message is “No Carrier Lock”, verify the RF Feed Port, Carrier Frequency, Data Rate, FEC Ratio, and ID Tag (if Tags are in use) settings. Also verify that the LNB LO frequency setting (in the IRD) is correct for the selected RF feed port.

3.If the alarm message is “RF signal overload”, then reduce the carrier power entering the Unity 4600. Either add in-line attenuation (a splitter will do) or remove line amplification in the RF circuit between the LNB and the IRD.

The Unity 4600 may not be authorized for the network’s Conditional Access. If the AUTH LED is OFF and the alarm message, "Unauthorized for CA” appears, contact your network provider to gain authorization in its Conditional Access database.

Missing an audio, video, or ASI output while others are okay

LEDS: ALARM or WARNING ON

Check the front-panel display for alarm or warning messages. Table 4.1: Alarm and Warning Descriptions on page 53 describes Unity 4600 alarm and warning messages. If the message definitions are too technical to help debug the problem, report the messages to your network provider.

LEDS: ALARM and WARNING OFF

If no alarms or warnings are shown, suspect a bad connection or mis-programming of the Unity 4600:

1.If audio or video are missing, check at the front-panel monitor jacks. If okay on the front monitors, check the signal connections from the rear of the unit to the destination. If an audio is missing from the rear panel outputs and cannot be detected at the front-panel monitors, check that a valid audio stream is selected for that port and that the network provider has supplied non-quiet programming on that audio.

2.If the ASI output is missing, check the signal connections from the rear of the unit to the destination. If okay, check with the network provider to verify what Program Mapping (Release 2 or later) may be in effect.

4.3 Alarms and Warnings

The alarm and warning system is intended to alert the local user of a present or impending loss of services. Table 4.1 below lists many (but not all) of the possible alarm and warning messages that the Unity 4600 may display. For problems you cannot resolve on your own, please contact Wegener Customer Service (see Chapter 5), and be prepared to describe your signal setup, Unity 4600 configuration, and any displayed alarm and warning messages.

Alarms

An alarm is asserted when the unit is unable (or presumed to be unable) to perform a required function or deliver required services.

Warnings

A warning is asserted when an alarm condition is imminent or to indicate other conditions requiring user attention.
