Polarization (NSUN Only) 
The Polarization settings are only relevant when the Redundancy Chain includes a 
Polarization switch.  In the case where a Polarization Switch is not present, the 
Polarization settings are not displayed.  Polarization must be set for the Backup 
Converter before the selection is made available for the Primary Converters.  
When the Polarization switch is installed, the only Polarization selections available for 
the Backup Converter are “VER” for vertical and “HOR” for horizontal.  When the Backup 
Converter detects the Polarization switch it reads the switch indicators and displays the 
current switch position.  Once detected in the system, the Polarization switch cannot be 
set to “N/A” (not applicable).  When there is no Polarization switch installed “N/A” for not 
applicable is displayed.  
 
To select the Polarization: 

• 

Press the left or right arrow key to select the Polarization field on the display. 

• 

Use the arrow keys to toggle between the “VER” vertical or “HOR” horizontal. 

• 

Press “ENTER” to set the displayed Polarization. 

• 

When the polarization of the converter in Standby is changed, the Polarization 
Switch is set to the new polarization. 

 
NSU-Converter Serial Link Subscreen 
 
The NSU-Converter serial link for each chain position can be enabled or disabled from a 
subscreen of the Converter Settings Subscreen. 

 

 

To enable or disable NSU-Converter Serial Link option  of a converter: 

• 

From the Chain Redundancy Status screen, press the left or right arrow key until 
cursor is just left of the desired chain position in the bottom line of the display.  

• 

Press “ENTER” to access the Converter Settings Subscreen. 

• 

Press the left or right arrow once (

→

) and press “ENTER”.  To access the NSU-

Converter Serial Link Subscreen.  The screen will appear as shown above.  The 
Address, Baud Rate and Parity are fixed, not customer adjustable, and are 
displayed for set-up information purposes only.  If the NSU-Converter Serial Link is 
disabled, the Address, Baud Rate and Parity will not be displayed. 

• 

Press the up or down arrow keys to toggle the Converter Remote Control between 
“ENABLED” and “DISABLED”. 

• 

Press “ENTER” to set the Converter Remote Control setting.
