 +Once logged in, telnet to the card in the correct slot (slot 1 to 6) in the case of the HEVC card it's normally slot 1 (if it's a single card)

 +To see the SMPTE-352 Link Numbers, enter the following command: 
 +\\  
 +    video status 
 +     
 +    The output will be similar to the following: 
 +     
 +    SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 1) 
 +    SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 2) 
 +    SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 3) 
 +    UHD input remapping: none 
 +    Video set to 2160p (interleaved format) at 59.94 frames/s 
 +    Video source is SDI (video locked) 
 +    Action on video loss is freeze frame without ident text 
 +    Front panel video monitor source is output 0 to NARA 
 +\\  
 +We can see in the above example that the SMPTE-352 link numbers are 0-0, 1-1, 2-2 and 3-3, so they are in the correct order. For this reason the line <color red>UHD input remapping</color> is set to <color red>none</color>, as no remapping is required. 
 +\\  
 +\\  
 +In the next example, the 3G-SDI inputs have been connected in an incorrect order: 
 +\\  
 +    SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 1) 
 +    SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 3) 
 +    SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 2) 
 +    UHD input remapping: SDI 0 -> UHD 0, SDI 1 -> UHD 1, SDI 2 -> UHD 3, SDI 3 -> UHD 2 
 +    Video set to 2160p (interleaved format) at 59.94 frames/s 
 +    Video source is SDI (video locked) 
 +    Action on video loss is freeze frame without ident text 
 +    Front panel video monitor source is output 0 to NARA 
 +\\  
 +Here we can see that the SMPTE-352 order is 0,1,3,2. So the last two inputs are swapped. Although the AVP HEVC card can cope with this, and the encode will look fine (because the SMPTE-352 link numbers are present) we can see that the <color red>UHD input remapping</color> is now reporting <color red>SDI 0 -> UHD 0, SDI 1 -> UHD 1, SDI 2 -> UHD 3, SDI 3 -> UHD 2</color> to let us know that the AVP is dealing with a mis-plugged input. 
 +\\  
 +\\  
 +I tested this in Quad mode (the AJA Ki Pro allows you to select either Sqare or 2SI output) and got the following: 
 +\\  
 +    SDI input 0 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    SDI input 1 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    SDI input 2 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    SDI input 3 locked to 1080p at 59.94 frames/s (SMPTE-352 link number 0) 
 +    UHD input remapping: none 
 +    Video set to 2160p (interleaved format) at 59.94 frames/s 
 +    Video source is SDI (video locked) 
 +    Action on video loss is freeze frame without ident text 
 +    Front panel video monitor source is output 0 to NARA 
 +\\  
 +Here we can see that there are no SMPTE-352 Link numbers present, so perhaps SMPTE-352 Link numbers are only part of the interleaved specification.
