Understanding the Status Field 

This field is permanently displayed and gives the user instant status on 
the four receivers within the central receiver. 

The alarms have the following meaning: 

 

Alarm 

Meaning for Receiver X (1 to 4) 

Demod Lock 

Green = demodulation is occurring 

Red = No demodulation (signal too weak, or tuned to incorrect 
frequency) 

Reception 

Green = signal received with zero packet errors 

Red = No reception 

Decoder Lock 

Green = video and audio decoders operating fully 

Red = video and audio decoders not operating (if this is occurring 
while reception is green, indicates that the service is scrambled or 
that the service names do not match) 

 

Using the Control Field 

The Central Receiver controller is structured around 7 main ‘Tabs’.  
These ‘Tabs’ logically divide the function of the unit and are entitled. 

 

Tab 

Meaning / Use 

Global 

Describes parameters specific to the entire central receiver, such as:  
software version numbers, quad split control and IP parameters. 

Streamer 

Contains parameters that control the Netstream option, such as 
streaming bitrate and IP parameters. 

Rebroadcast 

Contains parameters that control the Rebroadcast option, such as 
microwave output parameters and selection of which services 
should be rebroadcast. 

Receiver 1 

Contains parameters that are specific to receiver 1, such as 
frequency, encryption key and RF status. 

Receiver 2 

Contains parameters that are specific to receiver 2, such as 
frequency, encryption key and RF status. 

Receiver 3 

Contains parameters that are specific to receiver 3, such as 
frequency, encryption key and RF status. 

Receiver 4 

Contains parameters that are specific to receiver 4, such as 
frequency, encryption key and RF status. 

 

The Global Tab 

The global tab describes parameters specific to the entire central receiver.  These 
parameters are shown below.
