4.2.4.  Displaying the Equalization Strength 

To display the Equalization strength, press the toggle switch one or more times until the 

EQ

 message is 

shown on the display.  After one second the applied equalization strength will be shown represented as a 
percentage of the maximum equalizer capability. (100% is equivalent to 300m of Belden 1694 cable) 
 

EQ 

 

0% to 100% 
LOS 

 

0% to 100%

 

Indicates applied equalization.  

LOS:

 

Indicates that no valid input signal is present. 

 

4.2.5.  Displaying the Video Standard 

The 7707VAT series modules detect the Video standard of the input signal and display this on the four-
digit card edge display.  The following list describes possible displays and their meaning. 
 

VSTD 

 

N270 
P270 
LSV 
EDH

 

 

N270:

 

SMPTE 259M-C, 270 Mb/s 4:2:2 Component 525 line 

P270:

 

SMPTE 259M-C, 270 Mb/s 4:2:2 Component 625 line 

LSV:

 

Indicates that no valid video signal is present on the input.  This 
message overrides the normal video standard message. 

EDH:

 

Indicates that there is an EDH error.  This message overrides 
the normal video standard message. 

 
On the 7707VAT or 7707VAT-U, when you are displaying one of the Video Standard messages, pressing 
and holding the pushbutton for 3 seconds will turn off the card edge EDH error indication.  The display will 
show 

EDH

 momentarily to indicate that EDH local reporting has been turned off and then the normal video 

standard message will be displayed. This does not affect the monitoring of EDH errors and reporting 
through SNMP over the VistaLink

®

 interface.  Pressing and holding the pushbutton for 3 seconds will turn 

on the card edge EDH error indication.  The display will show 

EDH

 momentarily to indicate that EDH local 

reporting has been turned on. 
 
On the 7707VAT-A4, the 

EDH

 menu item is used to turn off the card edge EDH error indication.  See 

section 5.5. 
 

4.2.6.  Displaying the Audio Sample Rate (7707VAT and 7707VAT-U only) 

The 7707VAT and 7707VAT-U detect the Audio sample rate of the audio on the AES inputs and displays 
this on the four-digit card edge display.  For brevity sake, only 

AS1

 will be discussed in the manual. 

 

A1S 

 

LSA2 
32K 
44K 
48K 
LSA1 
LSA2

 

 

32K

 

AES Audio with 32 kHz sample rate is being received and output 

44K

 

AES Audio with 44.1 kHz sample rate is being received and 
output 

48K

 

AES Audio with 48 kHz sample rate is being received and output 

LSA1

 

Indicates that no valid AES1 signal is being received. This 
message overrides the normal audio sample rate message. 

LSA2

 

Indicates that no valid AES2 signal is being received. This 
message overrides the normal audio sample rate message.
